Title: EM-1/Artemis 1 Orion Service Module updates
Post by: RocketDoc on 05/12/2014 07:13 pm
Is there any information about the dimensions of the Orion Service Module?? I am trying to make a 1\12 scale model of the system, for my collection, and I have only found a length, that says it is 15.8 feet long. This is a start, but, it does not give diameters of the inner cylinder and solar cell panels...etc... Can you help???

Thank you so very much!!!

The ESM design is substantially different to ATV. ESM is designed for a completely different mission. See attached file, with the provisos that:
- as Jim said, ESM has not completed its design reviews. In fact, it is currently undergoing PDR.
- The formal industry proposal for the complete development (Phase C/D in ESA jargon) has not yet been submitted, so the technical baseline is still a bit fuzzy.
- the attached information is about 1 year old.
- with any luck, ESA might release more info after the Phase C/D contract is awarded.

Ok, Thanks for the info so far, I have managed to get the basic dimensions I need for the SM. Now, finding dimensions for the LAS are rather vague. I know it is 36" in diameter, but, I do not know the length of the powered portion, the escape jettison, the nose cone etc... I need a bit more details , so I can make an accurate scale model of that subsystem, along with my complete model.

Thanks again for all of your help. When I get this completed, I will take some pictures and upload them here. I may offer detailed plans sometime later, depending how they turn out.

Thanks Millions folks for your help!!!

This is only a mock up for eft 1, build by nasa/LM. It is not a SM at all, as DIV/Orion is making all the propulsion, no life support, etc.

"A working service module is not required for this test so instead NASA contractor Lockheed Martin built an adapter derived from the structural design of the service module to attach the Orion test model to its launcher."

ATV technology for the new Orion space capsule:
390 million euro contract secures expertise of German aerospace industry

The Russian cargo and drive module "Zarya" - German for "Sunrise" - began on 20 November 1998, the construction of the International Space Station. The ISS is now the largest and most complex research laboratory in space, a unique and
unique test environment for scientific and technological experiments in weightlessness.

Germany is about 40 percent of the development and operating costs largest European ISS partners. The ATV (Automated Transfer Vehicle) is the European supply vehicle for the ISS. All five are in ATV "Airbus Defence and Space"
been built in Bremen. The last room of this series freighter docked on August 12, 2014, the ISS, to leave the space station in February 2015 and then burn up in the Earth's atmosphere. But the developed technologies for the ATV
are not lost. They flow in the European Service Module ESM for the new US space capsule Orion, which is to explore space beyond low-Earth orbit and the ISS.

"NASA speaks to us with this offer from a great confidence We ask the ESM for the first time a critical component for future NASA missions -. And indeed for manned and unmanned missions," said Dr. Rolf Densing, ESA's Director of Programmes
in the space management of the Deutsches Zentrum für Luft- und Raumfahrt (DLR). Thus, the technical know-how in Germany remain not only maintained, but could even be expanded. "This is for us a clear option for the future. The ESM is
a meaningful continuation of the begun with the ISS cooperation with new accents ", so Densing on. In addition to scientific experiments could at longer exploration missions, technologies such as life-support systems are tested
- For planetary scientists to interesting new research areas and objectives could open for the astronautical space also.

With the development and construction of the service module for the Orion capsule, the European Space Agency ESA has commissioned the aerospace company "Airbus Defence and Space" on Nov. 17, 2014. The contract for 390 million Euros have, Thomas Reiter,
ESA Director of Human Spaceflight and Operations, and Bart Reijnen, head of Orbital Systems and Space Exploration at "Airbus Defence and Space" in Bremen, in the presence of Brigitte Zypries, Parliamentary State Secretary, Federal Ministry of Economics
and coordinator for the aerospace, signed in Berlin. The service module for propulsion, power supply, thermal control, and storage essential supplies such as water and oxygen for the American capsule
responsible.

The first flight of the Orion space capsule with the European service module is planned for 2017/2018. It is an unmanned flight to the moon and back. If the NASA exercise the option for a second ESM, should the second mission from 2020/2021
control a previously captured asteroid with astronauts on board and bring back specimens. After the release of system designs for the service module in May 2014. Now the detailed definition phase has begun, the first hardware is built.

Orion and the European Service Module

The US space capsule Orion is designed for manned missions to the moon, asteroids and for missions in the depths of space. Developed for NASA and builds "Lockheed Martin Space Systems" the space capsule for four or
more astronauts. For the drive and the energy supply and storage of important supplies such as water and oxygen to the care based on ATV technology European Service Module ESM. Together form the capsule and the Orion
ESM the multifunction spacecraft MPCV (Multi Purpose Crew Vehicle). On December 4, 2014, a first suborbital test flight of an unmanned Orion capsule on a US Delta IV Heavy rocket is planned - with a dummy service module.
Using the ESM, the MPCV could the international space station ISS fly.

MEDIA ADVISORY M15-116

NASA Invites Media to Orion Spacecraft Parachute Test in Arizona
 
NASA is inviting media to attend a test of the Orion spacecraft’s parachutes on Wednesday, Aug. 26 at the U.S. Army’s Yuma Proving Ground in Arizona. An engineering model of the spacecraft will drop from an airplane 35,000 feet up to evaluate how it fares when the parachute system does not perform as expected.

During the test, Orion engineers will carry out a scenario in which one of the spacecraft’s two drogue parachutes and one of its three main parachutes fail. This high-risk assessment is the penultimate drop test of the scheduled engineering evaluations leading up to next year’s tests to qualify the parachute system for crewed flights.

Media will have the opportunity to interview Orion engineers, see the model up close and view the test from the drop zone. To attend, media must contact Rachel Kraft at [email protected] by noon EDT Wednesday, Aug. 12.

Orion’s parachutes, critical to the safe return of the spacecraft to Earth, performed flawlessly during the spacecraft’s uncrewed flight test in December 2014, helping slow the capsule from its high-speed re-entry through Earth’s atmosphere from approximately 20,000 mph to about 20 mph when the spacecraft splashed down in the Pacific Ocean.

The Orion spacecraft is built to take humans farther than they’ve ever gone before, including to an asteroid and Mars. The spacecraft will serve as the exploration vehicle that carrier crews to space, provides emergency abort capabilities, sustains the crew during space travel, and provides safe re-entry from deep space. Orion will launch on NASA’s new heavy-lift rocket, the Space Launch System.

Official ESA reporting (via ESA Bulletin) on ESM progress over the past two years is below.
These official reports are very scarce on detail. No images provided.


August 2013 (ESA Bulletin 155)
The contract proposal for Phase-B2 of the MPCV European
Service Module (ESM) was approved until close of the
PDR. The full contract proposal will be presented at the
end of 2013. The ESM system PDR will be conducted at the
beginning of November.


November 2013 (ESA Bulletin 156)
The PDR began in September. The PDR board will be
conducted in November. The updated MPCV-ESM contract
proposal will be presented in November. The second
financial slice of the MPCV-ESM project will be part of the
third Financial Binding Commitment to be approved at the
Ministerial Council in 2014. Technical exchanges were made
with NASA to identify concrete options for the extension of
the cooperation in Transportation Systems for Exploration
beyond the initial MPCV-ESM contribution, as foreseen by
the barter for the ISS Common Systems Operations Costs
(CSOC) compensation.


February 2014 (ESA Bulletin 157)
The PDR was postponed to May in order to give more time
to design trade-offs and to address the excess mass issue in
more detail. A new PDR schedule was agreed with all parties
and all milestones of this plan have been met. The mass was
reduced close to the requirement. The impact of the PDR delay
overall will be minimised by starting Phase-C/D activities
that do not depend on the system PDR. A fully consolidated
MPCV-level schedule will be agreed after the system PDR.


May 2014 (ESA Bulletin 158)
Recovery measures were implemented to get back on
track for FM1 shipment date of March 2017. The mass
non-compliance has been improved, and the remaining
over mass is considered manageable. Savings have been
identified with a new concept of a bellow water tank.
Deletion of a Command (and) Monitoring Unit should
allow a further saving. Clarification on Thermal Control
System mass increase and assessment of an alternative
radiator layout is under way. The MPCV mission data for
the ESM design and verification were baselined. The Crew
Module Adapter SM mechanical interface design was
agreed. The MPCV PDR is scheduled for 15 May with all
intermediate milestones achieved.


August 2014 (ESA Bulletin 159)
The PDR for the Multi-Purpose Crew Vehicle European
Service Module (MPCV-ESM) was held on 15 May. ESA and
NASA board members endorsed the project to proceed to
the CDR. The industrial Phase-C/D proposal was received
and the review started.


November 2014 (ESA Bulletin 160)
The system PDR for the MPCV-ESM was closed. Authorisation
to negotiate the Phase-C/D contract was granted after the
third Tender Evaluation Board on 25 August. Phase-C/D
contract negotiation is almost complete, with agreement
found on all major issues. NASA agreed to the ESM delivery
date of 29 January 2017.


1st Quarter 2015 (ESA Bulletin 161)
The industrial Phase-C/D contract between ESA and Airbus
was signed in November. Most sub-system PDRs took place,
with the last one to be concluded in April. NASA’s Orion
Exploration Test Flight 5 December 2014 was successful. The
next major milestone is the ESM system CDR in December (2015).


2nd Quarter 2015 (ESA Bulletin 162)
Almost all subsystem PDRs have been concluded, and several
important design changes on system level were agreed
with NASA. Among those changes is the manufacturing
of a second Structural Test Assembly that will recover the
schedule delay caused by other NASA change requests.
Manufacturing of equipment breadboards has made
progress and no issues were discovered. The schedule is still
very challenging.

Interesting to note from the EM-1 integrated mission milestones summary is that no less than three major  elements are on the critical path:
- Crew Module
- European Service Module
- Core Stage

On a further note: I'm getting messages that ESM CDR possibly will be delayed, by as much as several months into early 2016, on account of STA testing at the contractor's has run into some problems.

NASA-Furnished Propulsion Slows Orion ESM Work At Airbus


Amy Svitak Frank Morring, Jr.

Wed, 2015-11-18 04:00

Work on a European service module (ESM) that will fly on NASA’s Orion crew capsule has slowed, due in part to the integration of a NASA-furnished propulsion system that flew on the space shuttle. The ESM development, underway at Airbus Defense and Space in Bremen, Germany, is facing challenges on several fronts: Finding background documentation at NASA necessary to qualify the customer-supplied propulsion systems, which date to the shuttle era; sharing the documentation with Airbus ...

NASA TV to Air Event Marking Arrival of Test Orion Powerhouse

NASA Television will broadcast an event marking the arrival of a full-size test version of the service module provided by the European Space Agency (ESA) for NASA’s Orion spacecraft at 12:30 p.m. EST on Monday, Nov. 30 at the agency’s Plum Brook Station in Sandusky, Ohio.

Event participants will be:
•Jim Free, director of NASA’s Glenn Research Center in Cleveland
•Greg Williams, deputy associate administrator for Human Exploration and Operations at NASA Headquarters in Washington
•Mark Kirasich, manager for the Orion Program at the agency’s Johnson Space Center in Houston
•Mike Hawes, program manager for Orion at Lockheed Martin
•Nico Dettmann, development department head at ESA
•Oliver Juckenhoefel, vice president and head of the European Service Module program at Airbus Defence and Space

A brief question-and-answer session will take place during the event with media on site and by phone. Media that wish to ask questions on the phone must email their name, media affiliation and phone number to Jan Wittry at [email protected] by noon EST on Fri., Nov. 27. The public also can ask questions during the briefing on social media using #AskNASA.

The Orion spacecraft is being developed to help send astronauts to deep space destinations, such as an asteroid placed in lunar orbit and Mars. It will launch on the agency’s Space Launch System rocket. ESA, along with its contractor Airbus Defence and Space, is providing the service module for Orion’s next mission, a partnership that will bring international cooperation to the journey to Mars. The service module will supply power and propulsion to the Orion spacecraft for Exploration Mission-1.

ESA and Airbus also provided the structural representation of the service module so that NASA may conduct rigorous tests to ensure the module can withstand the trip to space. The multi-month test campaign will take place at Plum Brook’s Space Power Facility. Plum Brook is home to some of the largest testing structures in the world, including one of the world’s largest vacuum chamber, the world's most powerful spacecraft acoustic test chamber, and the world's highest capacity and most powerful spacecraft vibration table.

Here's a zinger:

Since the OSM is designed for deep-space missions, what is its expected consumables base? I would suspect it would be designed to be dormant for months on end, but isn't that an ageing challenge when months turn to years? Would its consumables be refuelable? Would the SM have repair options? There's only so much talk to fix something while in deep space well away from home.

I might be asking questions with no answer since Orion's missions aren't lined up, nor are the official specs defined yet, if I read correctly up-thread. There's also the matter of crew habitation and fuels from there.

Excellent.  Okay, here's two questions to request offhand:

1) Does ESA have a specific date when the service module for the Orion of EM-1 shall be built and ready?
2) Is the delta-v budget capability for Orion's service module still roughly 1.4 km/s or has that changed?

Interesting information bit: The pressure regulation for the fuel tanks will be done electronically (the Airbus guy said that, when asked what new technology will be used). Typically these pressure regulators are mechanically. The pressure difference acts on a piston which in turn acts on a valve (both parts are typically integrated into each other). Mechanically working regulators are very robust (close to no parts in it). But they change their regulation behaviour (dynamics) based on current pressure.

An electronic pressure regulators might allow to use more He (as the regulator will be stable even at low pressures). I wonder if they plan do depressurize the system in some conditions (e.g. when docked to a habitat, or for diagnostics reason).

Doesn't appear to be reading from a script. Very good speech by the lawmaker. Clearly a Plum Brook fan.
side note re: Marcy Kaptur

Seeing Ms. Kaptur as the US Representative whose district encompasses Plum Brook was a surprise, until I re-familiarized myself with Ohio's congressional redistricting after the 2010 census.

Wow!

First, she's held this congressional seat since 1983.

When I was a student at the University of Toledo (I haven't found an on-line map of the Congressional districts resulting from the 1980 census), I'm sure her district was more centrally located on Toledo.

(Ohio has lost 5 Congressional seats since the 1990 census.)

Secondly, now the 9th District stretches along the shores of Lake Erie, and not into the hinterlands, all the way from the western city limits of Toledo into central Cleveland!

Unlike some other amphibians, "gerrymanders" are thriving here in the USA!

I know this is short notice, but I will be attending the event today and if anyone has any questions for me to ask, let me know.

Excellent.  Okay, here's two questions to request offhand:

1) Does ESA have a specific date when the service module for the Orion of EM-1 shall be built and ready?
2) Is the delta-v budget capability for Orion's service module still roughly 1.4 km/s or has that changed?


1) I asked this during our meet & greet before the event.  The current schedule has the the service module arriving to Kennedy Space Center in January of 2017.  During the facility tour it was brought up again and one of the Engineers from the Glenn Research station said that the current plan is to integrate Orion and the service module at KSC before shipping to the Space Power Facility for testing starting in March-April via the Super Guppy cargo plane.


2) I asked a couple people, and they couldn't get a good answer from anyone.  I tried asking Mr. Dettmann, but the European reporters had him tied up even after our tour started.  I'll follow up and see if I can find out.

Plum Brook Welcomes Orion’s Powerhouse

Published on Nov 30, 2015
An event on Nov. 30 at NASA’s Plum Brook Station facility in Sandusky, Ohio marked the arrival of a full-size test version of the service module provided by the European Space Agency (ESA) for NASA’s Orion spacecraft. The module will supply the spacecraft’s power, in-space propulsion and air and water for astronauts onboard Orion, which is being developed to help send humans to deep space destinations, such as an asteroid placed in lunar orbit and Mars. A rigorous test campaign will be conducted at Plum Brook to ensure the module can withstand the trip to space.

I only see evidence to the contrary. For example the fact that the Apollo CM/SM was a lot more expensive than Gemini, in fact almost as expensive as the Saturn V. Or the fact that NASA organized commercial crew for access to LEO instead of using Orion.

Sure NASA could organize a competition for a BEO capsule, but I'm sure Lockheed would win easily due to the headstart they have.

The service module was outsourced to the ESA because NASA had priced itself out of the ability to build it themselves.

Orion is big and heavy because it goes to the Moon and back. A Dragon modified for that purpose would be equally big and heavy.

There was no competition for a BEO capsule, only for LEO. The fact that Lockheed did not even bid with a stripped-down Orion only confirms my suspicion that its difficult to make a BEO capsule into a competitive LEO capsule and vice versa.

Orion was built heavy on purpose but it wasn't actually necessary. NASA wanted a capsule that could be used in space for 3 weeks without a habitat. It's also larger than it needs to be which means that it can't be lifted by an Atlas V.

Let's not forget that NASA is not monolithic in thought, and that NASA was originally pursuing a completely different design for Orion when Lockheed Martin was awarded the contract for a delta-winged vehicle.  Michael Griffin then took over as NASA Administrator and after he implemented the Exploration Systems Architecture Study Orion was changed to what we have now - which is a design that Griffin developed as part of a study for the Planetary Society.

So no, NASA did not originally want a capsule.  And what we have today is what one person in NASA, Michael Griffin, really thought NASA should have.  We'll never know which was the better choice, but we need to remember how we got to where we are today.

You make the mistake of assuming that SpaceX would, under equal requirements, come up with the same behemoth vehicle that NASA forced onto LockMart. You completely ignore the fact that SpaceX has a tendency to do things a tad different from the rest of the aerospace industry.

The lunar Dragon from the Evolvable Lunar Architecture by the way is almost as heavy as Orion, all things included, and can only keep a crew of 4 alive for 14 days (not that I trust the study, but its the only one I know of).

http://www.space.com/1088-florida-hopes-host-cev-construction.html

As I recall, that Delta Winged Body was an initial proposal from LMCO and not the one they actually sent in.  In a similar fashion, NG/Boeing released a Soyuz Like vehicle as their product.  (Note:  At the time I worked for NG in an LMCO building on a battle simulation program.)

At the time, I asked the POC given on the NG blurb if there was any information available.  I did it from my LMCO e-mail, which made him suspicious, so I told him what my situation was and switched to my NG address.  essentially he said it was a deception plan.

When I watched the announcement, there was, again, no real difference to the casual eye between NG and LMCO, except the solar panels.  NG were long and rectangular and LMCOs were Compact and circular/stop sign shaped.  They both appeared to be the same size.

After the contract was awarded, NASA went to the incredible shrinking SM as they tried to make the program work.

Mind you, this is recollection on my part and I  no longer have the various released drawings of the various iterations, so I may be completely wrong.

- Orion and Lunar Dragon cannot be compared as apples-to-apples: Orion does not carry it's LAS all the way to lunar orbit. That add's quite a bit of mass to Dragon.

Have you even bothered to read that study properly?
- If you had you would have noticed that LLO insertion is not done by Dragon's LAS engines but by the still-attached Falcon 9 second stage.
- LLO departure (aka Trans Earth Injection) is done by Dragon's LAS engines using propellants being drawn from a second attached trunk.
- The propellants stored in the Dragon service module (Dragon's own, internal propellant supply) is exclusively reserved for LAS duties and Earth propulsive landing. So my point, that Dragon carries it's LAS systems (including the needed propellants) all the way to the moon and back to Earth again, stands. It also means that comparing lunar Orion and lunar Dragon on weight alone is not apples-to-apples.

Fair enough, sustract ~1.4t of fuel for landing and an additional ~0.5t from the trunk. Doesn't change the big picture. You have a less capable vehicle weighting ~3t less than Orion.

I'm still waiting for a technical argument why a lunar Dragon/CST-100 should be less heavy given equal requirements.

This is incorrect. Once launch is successful, what would have been used for LAS (all of it) is split up between mission propulsion needs (orbit/trajectory adjustment and attitude) and propulsive landing. There is no separate propellant supply for the Draco thrusters.

Reserved for LAS duties during launch. The added trunk is left behind when a launch escape is required. The added trunk also is not there when a propulsive landing is performed. That's what was meant with the propellants in the Dragon service section being reserved (as in: set aside) for LAS or propulsive landing duties.
Only propellants from the added trunk are used for the TEI burn.

It does not matter if this not actually the case. What matters is what assumptions are made in the study.

Then the assumptions are wrong, and the study is questionable. How can propellant be reserved for LAS duties when the launch has already happened?

Launch escape requires ~300m/s. Landing 200m/s according to the study and deorbiting probably ~100m/s. It does add up.

Yes, *I* know it adds up. The Dragon 2 propellant is either used for LAS *OR* in-space/deorbit + landing. I'm merely correcting the impression that once in space, a portion of the propellant remains set aside for LAS, which is not true.

Inside a rocket’s belly
 

An unusual view of a spacecraft – looking from below, directly into the thruster nozzles. This is a test version of ESA’s service module for NASA’s Orion spacecraft that will send astronauts further into space than ever before.
 
The European Service Module provides electricity, water, oxygen and nitrogen, and thermal control as well as propelling the spacecraft.
 
The large cone is the spacecraft’s main engine, the same model that was used on the Space Shuttle for orbital manoeuvres. The surrounding red cones are auxiliary thrusters. The engines will provide almost 30 kN of thrust, only one-tenth that of a Jumbo Jet engine, but enough to manoeuvre in space. More thrusters are carried on the module’s sides.
 
This structural test model is used for testing purposes before installing the real thing. It is as close to the flight version as possible while keeping costs and development time manageable. The structure and weight are the same, while mass equivalents stand in for electronics boxes not needed for the series of tests.
 
The model was installed under a test version of the Crew Module Adapter, and sits on the Spacecraft Adapter that will attach Orion to its launch vehicle. This is the first time the European hardware has been physically connected to NASA’s elements.
 
The service module will be shaken at NASA’s Plum Brook station in Sandusky, Ohio, USA, to recreate the vibrations of launch, as well as being subjected to acoustic and shock environments.

Propulsion Module arrives in Stockholm
Posted on 18 Feb 2016

Another important part of the service module for the Orion spacecraft is getting ready for testing. The Propulsion Qualification Module will ensure that Orion’s thrusters and fuel system work, used to orient the spacecraft and send it back to Earth.

OHB Sweden and Airbus DS will do the final integration of this part of the spacecraft test module in Stockholm, Sweden. The pictures show the distinctive fuel tanks that will hold mixed oxides of nitrogen (MON) and monomethyl hydrazine (MMH) – two tanks for each propellant. The tanks were built in Bremen and delivered to Sweden to be put in the Propulsion Qualification Module.

The qualification module will be shipped to NASA's White Sands test facility in the USA this summer with the engines being fired up for firsts in September.

Meanwhile in Switzerland RUAG, delivered the Solar Array Drive Electronics unit is now available for testing. The qualification model Solar Array is also complete, built by Airbus DS in The Netherlands.

ESA’s Service Module is a true collaboration involving companies from all over Europe with Airbus DS as main contractor.

Orion Test Hardware in Position for Solar Array Test
Last Updated February 25, 2016 - Kelly Heidman

Engineers and technicians at NASA Glenn's Plum Brook Station in Sandusky, Ohio, are preparing for the first major test in the campaign to verify the structural integrity of Orion’s service module for Exploration Mission-1, the spacecraft’s first flight atop the agency’s Space Launch System (SLS) rocket. Orion’s service module, which will power and propel the vehicle and supply it with air and water, is being provided by ESA and built by Airbus Defence and Space. The solar array wing deployment test will verify that the qualification model wing unfurls as expected. On Saturday, Feb. 20, an international team of engineers and technicians lifted and tilted the service module test article -- which includes structural representations of the service module, crew module adapter, and spacecraft adapter -- to a 90 degree angle to position it for the deployment test of one of Orion’s four solar arrays. The next step in preparation for the test is attaching the solar array before the Feb. 29 deployment test. This is the first in a series of crucial tests to verify the service module’s structural integrity and ability to withstand the dynamic launch environment atop the SLS rocket.

Not even close. Remember, what you are seeing here are the structural test articles of the ESM and the solar arrays. They will be in all kinds of test for the next year. By that time the actual flight hardware will have arrived in the USA for yet another round of testing, lasting nearly 10 months. NASA and ESA will be lucky if the complete Orion (CM + CMA + ESM) are ready for EM-1 in late 2018. But right now the planning is cutting it extremely tight.

Testing solar array
1 Mar 2016 - julien

On 29 February a test model of Orion’s solar array was unfolded at NASA’s Plum Brook Station test facility in Sandusky, Ohio to check everything works as expected. The solar panels were made by Airbus Defence and Space in the Netherlands for the ESA module that will supply power and life support for up to four astronauts.

Each wing stretches more than 7 m, folded inside the Space Launch Systems rocket that will launch the spacecraft on its first unmanned mission in 2018. Orion sports four wings of three panels with 1242 cells per panel to provide 11.1 kW of power – enough to run two typical European households. The distinctive X-wings are an evolution and improvement of ESA’s Automated Transfer Vehicle.

The test was passed with flying colours as the 260 kg array unfurled into its flight configuration. The stresses of flying to the Moon and beyond – and back again – mean the array is designed to bend up to 60º forward and backward, much like a bird in flight.

“That broad movement meant we had to design the wing with thickened solar panels and reinforced hinges and beams, which required extensive testing,” says Arnaud de Jong, head of the Airbus Defence and Space Solar Array team in Leiden, the Netherlands.  The wing tips are expected to deflect more than a metre. A camera on each wing tip, looking back at the spacecraft, will closely monitor the movement.

Further tests will look at how the solar array handles acoustic shocks, vibrations and other shock tests in the following months.

Orion [SM] update March-April
Posted on 26 Apr 2016 by julien

In February we reported on Orion spacecraft’s propulsion test qualification model main elements arriving in Sweden for assembling – time for an update. Although the Propulsion Qualification Module (PQM) will not go to space the model serves an important role in development: ensuring everything works as planned.

The model has four stainless-steel tanks 2000 litres each with walls 1 cm thick. The tanks will hold the propellants at a pressure of 25 bar with a total capacity of nine tonnes . Other elemenst of the PQM  include two high-pressure helium tanks; pressure-control systems; the sensing and command system with drive electronics; the propellant lines with shut-off valves; filters; and of course engines that will propel and orient Orion.

The engines that are part of the propulsion system include a US Space Shuttle engine as main engine, eight auxiliary thrusters and 12 smaller thrusters for the Reaction Control System, made by Airbus DS in  Lampoldshausen (Germany).

The integration of these parts for testing is taking place in Sweden with delivery planned for July/August 2016. The model will be tested in end 2016 or early 2017 including  firing the engines at White Sands Test Facility in New Mexico, USA.

Meanwhile the Solar Array Wing will start its acoustic testing to recreate the intense sounds and vibrations of launch in Plum Brook, USA, in April. The Exploration Mission-1 flight structure ­– the actual chassis that will be launched into space in 2018 – is scheduled to arrive end of April in Bremen, Germany as well.

From April 11 to June 16 an important Critical Design Review is happening a moment when any concerns about the spacecraft’s design are reviewed before fixing the design once and for all. A cutoff point in all spacecraft design, from this moment no more changes can easily be made…

Call for Media: Integration of Orion’s European Service Module

Contracted by ESA, Airbus Defence and Space is building the European Service Module for NASA’s Orion spacecraft. Integration of the module’s flight model for
Orion’s first deep-space  mission has begun at the company’s Bremen site, Germany, where media representatives are invited to attend a press briefing on 19 May.


ESA and Airbus are playing a major role in the next step in human spaceflight by developing the European Service Module for Orion, NASA’s next-generation exploration
spacecraft that will send astronauts on missions beyond the Moon. 

The module sits below the crew capsule, and provides propulsion, power, thermal control, water and air.

The first full Orion mission, Exploration Mission-1, will be an uncrewed flight more than 64 000 km beyond the Moon in 2018 to demonstrate the vehicle’s performance
before a crewed flight. 

Based on decisions from the ESA Ministerial Council meeting in November 2012, the European industrial team led by Airbus Defence and Space is developing and
building the European Service Module for Exploration Mission-1, drawing on extensive experience gained from building the five Automated Transfer Vehicle supply
ferries for the International Space Station.

What are those dark rectangular structures placed between the solar cells?

Correct. In the stowed configuration each array is supported by four posts sticking out of the ESM outher shell. A wire runs from each wire-end on the outermost panel of an array, through the holes in the center and inner panels into the support post. This is how the panels are held in their stowed configuration.
The support post contains a thermal knife that cuts the wire and releases the array. Springs in the array hinges do the actual work to deploy the arrays.
So, each array is secured for launch by four wires. It thus requires four thermal knifes to function perfectly for a single array to deploy, 16 thermal knifes for the full set of four solar arrays. Naturally, the thermal knifes are fully redundant. Each knife consists of actually two independantly powered thermal cutters. If one fails, the other will still be able to cut the wire.
On the flight arrays most of the black rectangular structures will actually be covered with photovoltaic cells. The single array shown on the images and footage of the deployment test is a structural model and holds only a handful of instrumented actual photovoltaic cells.
With regards to stowage and deployment these arrays for ESM are identical to the ones on ATV. They are better known as flatpack arrays and have been used on a good number of ESA and commercial satellites. With regards to the basic design the ESM solar arrays are largely standard.

I am guessing it is because I think there is only a contract to supply the ESM for just the first mission.  While unlikely, this does leave the option open for for it to be replaced down the road with an American version.  I suspect the ESM will continue to be supplied as needed for further missions once the details and timing of those get finalized.

Well, it's not like the service module can be re-used, it is totally an expendable piece of the Orion spacecraft.  So, yeah, either NASA needs to let a contract for an American firm to build service modules for future flights, or the ESM can't be a one-off...

The Orion Service Module design is based on ESA's Automated Transfer Vehicle (ATV) spacecraft, and is not a NASA design.

So since it's based on a European design, it's called the European Service Module.  No doubt if it was NASA designed and U.S. built, it would just be called the "Service Module".

I disagree. Arrays which can be canted during engine boosts are pretty non standard (see Orion EM-1 youtube video).
I was talking about the solar arrays themselves. The canting feature is in a separate system known as the solar array drive assembly. It's the set of hinge-motors that structurally connect the solar array to the main body of the ESM.
The hinge was always going to have a motor to allow the solar array to rotate through the long-axis of the deployed array. Now a second motorized hinge has been added to allow the solar array to also cant upwards and downwards.
But with regards to the solar arrays themselves: they are pretty much standard constructions. Only the solar cells attached to them differ in that they are suitable for deep-space use. Much like the ones on the Rosetta solar arrays.

Wrong assumption. Europe is not slapping the European title on to it. NASA did in fact.
Orion has a Service Module. That Service Module consist of four major components:

1. Crew Module Adaptor (CMA).
This is the 'cradle' that the CM is nesting in and forms the wide top part of the Service Module. This component is the structural 'bridge' between the CM and the ESM. It remains attached to the CM until just shortly before re-entry. The CMA is constructed in the USA.

2. European Service Module (ESM).
This is the Service Module component that attaches to the other end of the CMA. It provides the CM with electrical power, the gases and fluids for ECLSS, via an umbilical running thru and outside the CMA. It also provides (amongst others) attitude control, active thermal control, passive thermal control and propulsion for the entire Orion spacecraft. However, it is important to note that the ESM is only one (but rather important) component of the Service Module. It does NOT constitute the entire Service Module. The ESM is constructed in Europe. The main propulsion system is US-made however given that it consists of a re-purposed space shuttle OMS engine.

3. Spacecraft Adaptor (SA)
The backside of the ESM interfaces with the top-ring of the SA. The bottom-ring of the SA interfaces with the launch vehicle adaptor. The SA is one of two parts of the Service Module that is discarded during launch into orbit. Orion separates from the launch vehicle at the SA-ESM separation-plane, leaving the SA attached to the launcher. The SA is constructed in the USA.

4. Spacecraft Adaptor Jettisoned Panels (SAJP)
The SA, bottomside of the CMA and outside of the ESM are protected, during launch, from the effects of high-speed flight thru the lower part of Earth atmosphere. This is done by encapsulting the SA and ESM in a barrel-like construction. This barrel consists of three jettisonable panels. The panels interface at the top with the bottom-outer-ring of the CMA and they interface at the bottom with the bottom-ring of the SA. The SAJP are constructed in the USA.

So, as you can see, the ESM is only part of the entire Service Module for Orion. The component needed a name. NASA chose to name it the ESM because it is the only one of the four major components that is not produced in the USA, but in Europe in stead.

This is to differentiate the ESA-designed and -supplied module from the presumptive American Service Module that I'm guessing is supposed to fly from EM-3 onwards.

Under current negotiations EM-3 will fly with an ESM. There are currently no concrete plans to invest in "doing" an American Service Module (although LockMart really would have loved to have one..but that station has passed). My sources also states that the IP for the ESM will not be passed to NASA. ESA knows they are holding the golden eggs. ESM gives them a golden opportunity to stay "in" the US Exploration program. "In" as in participating in the planned missions. Not just with the ESM, but with crew participation as well. ESM is no longer about bartering for "just" continued participation in ISS.

There is only one little issue with your nice scenario : that the real decision makers, the ESA member states, go along. They are notorious for preferring development to recurring production. See ATV which died after the fifth copy.

No problem there IMO. The second ESM (for EM-2) is significantly more developed than the first one (for EM-1). Preliminary studies are already being performed into the capabilities required for the third one and beyond. Besides, one example (ATV) makes for lousy predictions.

You should not even remotely be surprised. Building and integrating your flight hardware BEFORE the CDR is "in the bag" is THE guarantee that things will get delayed. ESA and Airbus knew this and took the gamble anyway. So, it bit them in the behind. I'm surprised the delay is "only" three months.

Prior to the ATV, ESA had no experience with man-rated craft, so this was actually a really important development for them (which has served to generate knowledge useful for the ESV).

You mean in the same way SX had no man rated experience?

Both ATV and Dragon had to meet full human rating rules in order to berth with the ISS. While Spacelab flew in the payload bay of the Shuttle. While Dragon 2 looks like it's structure has diverged quite a lot from Dragon 1 I'd expect internally it's basic systems are close to identical.

The real thing

The European Service Module that will power NASA’s Orion spacecraft to the Moon and beyond is taking shape in the assembly hall at Airbus Defence and Space,  Bremen, Germany. The spacecraft module will provide propulsion, electricity, water, oxygen and nitrogen and thermal control.

Seen here is the primary structure that provides rigidity to the European Service Module much like the chassis of a car. It absorbs the vibrations and energy from launch while a secondary structure protects the module from micrometeoroids and space debris.

Assembly of the thousands of components needed to build the advanced spacecraft started on 19 May with the arrival of the primary structure that was shipped from Turin, Italy, by Thales Alenia Space. In 2018 this structure will be an element of the European Service Module that will be launched into space, as part of the Orion spacecraft, on its first mission to fly more than 64 000 km beyond the Moon and back.

In the background is a poster of ESA’s Automated Transfer Vehicle (ATV) that was also assembled in this hall in Bremen. Five ATVs flew to the International Space Station to deliver supplies and raise its orbit.  Developing ATV provided the experience necessary to develop the European Service Module in Europe.

And you are not likely to get a detailed answer soon. The SM for EM-1 is already different from the STA as a result of the recently completed CDR. For EM-2, the lessons learned from EM-1 will most likely be incorporated, but they will have to fly EM-1 first. It's not just lessons learned from building and integrating the (E)SM. Flight experience will likely account for additional modifications to the EM-2 flight model.

Except that when EM-1 will fly, the EM-2 ESM will most probably be in late assembly stage.
No room for design changes at that point, except for small local tweaks...

Hmm good point, but hard to say.  Considering EM-2 is scheduled for 2023, which is 5 years after EM-1, that's a lot of time.  I'd say the ESM is more likely to be in the early assembly stages, not late, in 2018...and that's assuming ESA doesn't delay assembly or NASA request changes.

I would assume the EM-1 ESM would prioritize propulsion and navigation, and the EM-2 ESM adds full life support on top of that going by bare essentials.  Aside from tweaking life support, wouldn't it be in NASA/ESA's best interests to keep the 2 modules as similar as possible to minimize R&D?

NASA officials have said that more funding could move the 2023 date to the left. But the question is, more funding compared to what? They can only be referring to the president's out-year funding profile which has a pretty low chance of being passed. There is no other document that they could be using to forecast funding. For instance, the PBR cuts SLS and Orion by 800 million over 2016 levels in 2017. Any chance of that cut actually happening? There is no cut in the house or senate bill and a continuing resolution will fund the programs at 2016 levels.

Don't agree. IMO, given that there is a three-to-five year gap between EM-1 and EM-2 it is much more likely that work on EM-2 has not even begun yet by the time EM-1 flies. Even at NASA's snails pace it does not take three years to build another flight vehicle and that particularly applies to the (E)SM. It is relatively simple compared to Crew Module.

Gearing up for Orion propulsion subsystem tests
Posted on 21 Sep 2016 by julien

Engineers are preparing for tests to qualify the propulsion subsystem, including the main engine, for Orion’s European-built service module that will propel the spacecraft during its flight in deep space.

They will test engineering units, fully representative of the engines that will equip the spacecraft that will fly with NASA’s Space Launch System rocket in late 2018.

The tests of the propulsion qualification model include tests of the engines, propellant feed systems, and propulsion control avionics. The tests will start at NASA’s White Sands Test Facility in New Mexico, USA, in spring 2017.

Orion’s service module main engine is a modified Orbital Manoeuvring System engine used before on the Space Shuttle that is being repurposed for use in the European service module.

The propulsion qualification model that will be used for testing will be shipped from Sweden to White Sands November 2016. It consists of two helium tanks (to pressurise the propellant tanks), propellant tanks, thrusters, piping, electronics, pressure control assemblies, a pressure regulation unit and propellant isolation equipment (valves).

Data from the testing at White Sands will verify the proper operation of the service module propulsion subsystem.

While the main engine and test facilities for the Propulsion Qualification Model are prepared for firing up, the main engine has been refurbished and tested at White Sands, and was shipped to NASA’s Johnson Space Center in Houston for vibration testing. The vibration testing is helping to ensure the engine can withstand the loads induced by the rocket during launch. After testing at the Johnson Space Center, the flight engine will be sent to Europe so ESA can integrate it into the Orion service module before delivery to NASA.

Orion and the European Service Module

Published on Apr 6, 2017

NASA’s Orion spacecraft will take astronauts to destinations at or beyond low Earth orbit. In January 2013, it was announced that ESA would provide the European Service Module (ESM) for Orion’s first uncrewed mission. Derived from ESA’s Automated Transfer Vehicle cargo spacecraft, the ESM will provide life support, propulsion and structural functions for Orion. In February 2017, a contract was signed for a second ESM to be used on Orion’s first crewed flight, which will carry astronauts beyond the Moon and back.

Set to be shipped to the USA around the New Year, ESA’s contribution to NASA’s Orion spacecraft is taking shape at Airbus in Bremen, Germany. This is no test article: the service module pictured here will fly into space by 2020, past the Moon and farther than any other human-rated spacecraft has ever flown before.

The service module will supply electricity, water, oxygen and nitrogen, propulsion and temperature control.

The blue circular frame is the support structure that holds the module as technicians work to get it ready. Yellow ties keep the 11 km of wiring in place as the thousands of components are installed and connected – the ties will be removed before flight. Behind the red support covers are the eight 490 N R-4D-11 thrusters, built by Aerojet.

Technicians are working in three shifts a day to assemble the components that are being shipped from all over Europe to complete this service module in just a few months’ time. In December it will be taken by road to Bremen airport and flown to NASA’s Kennedy Space Center in Florida to meet its crew capsule.

"1st successful test for @NASA_Orion's propulsion module. Hot firing test starts campaign at @NASA White Sands. Info: http://bit.ly/2fPYVw8"

https://orionesm.airbusdefenceandspace.com/blog/orion-propulsion-test/

"Hot firing test mark the start of the Orion test campaign at NASA White Sands

The Propulsion Qualification Module (PQM) is a test module for Orion’s mission critical propulsion system. Currently Airbus, ESA and NASA engineers run a test campaign  at the NASA test facility in White Sands (US, New Mexico). Although the PQM and its four propellant tanks will never see space, this is an important step in the development of the Orion programme. Complex systems must first be tested and qualified on Earth before being used as flight hardware in space. The challenge in manufacturing the test tanks was therefore to satisfy the numerous technical specifications, such as cleanliness, fuel compatibility and watertightness, that will also apply to the real propulsion system.

"It is an important milestone, a huge success for the whole team and it perfectly demonstrates our engineering competence. My congratulations to the team but let’s not forget that we still have more tests to come."

Bas Theelen, Orion Programme Manager, Airbus

The flight model will have 33 engines to provide thrust and to manoeuvre the spacecraft on all axes. The test module is equipped with less engines, among them a re-used engine which last flight occurred in 2011 with Space Shuttle Atlantis (OMS–E: Orbital Manoeuvre System Engine). “I am delighted to see these first successful hot firings” says Bas Theelen, Orion Programme Manager at Airbus Space Systems.The test campaign is expected to be terminated at the end of 2017 or the beginning of 2018."

European Service Module Structure

In a series of blog posts based on images taken at the Thales Alenia Space facility in Turin, Italy, we will now have a look at part of Orion’s structure.

This tank bulkhead made of aluminium forms the top platform of the second European Service Module – the one that will fly with astronauts. It is almost 5 metres in diameter.

These pictures show work on the top bulkhead that is located inside the Crew Module Adapter directly under the Crew Module Heat Shield of Orion’s second exploration mission

The bulkhead is a key part of the primary structure providing structural rigidity to the Orion spacecraft much like the chassis of a car. It absorbs the vibrations and energy from launch.

The round holes in the bulkhead allow for tanks to poke through. The four larger holes are for tanks that each hold 2000 l of propellant while the four smaller holes are for three oxygen tanks, and one nitrogen tank.

In the middle of the structure is a square opening for cabling, and helium tanks, more on this part in another blog entry tomorrow…

Orion’s European Service Module “Wall” Panels

In a series of blog posts based on images taken at Thales Alenia Space building facility in Turin, Italy, we will have a look at the vertical panels that form part of Orion’s European Service Module primary structure, these images show work on the second service module that will propel astronauts beyond the Moon and provide essentials such as water, air, electricity and power.

The black panels are prepared on a table before being installed into the Service Module vertically. They are made of a lightweight composite material known as carbon-fibre reinforced-plastic. The honeycomb structure provides rigidity while keeping weight down.

The large holes when installed keep the weight down even more but also allow the technicians and engineers access to the mass of meticulously laid cables to be installed – over 11 km in total! The silver circles are mounting points for equipment and cables. Most of these will be installed in Bremen, Germany, at the Airbus integration hall where the complete service module is assembled.

Inside the four panels two helium tanks will be installed that will be used to push propellant to Orion’s engines during its mission.

Brackets for holding the tank bulkheads (discussed in this blog post) are already attached to the bottom bulkhead and ready for installing the top bulkhead. In the photo below the engineers are standing in the hole that allows room for the propellant tanks.

These images show the beginnings of the spacecraft structure that will send human beings further from Earth than ever before – we will keep you updated in more blog posts.

Orion Service Module-2 Structure Complete

Wrapping up our blog entries on the frame of the second European Service module for Orion, these pictures show the completed internal structure for Flight Model-2. It will support up to four astronauts and send them further than any human being has ever been from Earth in a few years.

The pictures show the two circular tank bulkheads in place, bolted to the vertical panels. The top ring will attach to the Crew Module Adapter that connects the Orion capsule to the service module.

The pictures were taken at the Thales Alenia Space facility in Turin, Italy, in November 2017.

This structure can be seen as the chassis of the Orion spacecraft, providing structural rigidity while absorbing vibrations and energy from launch.

The holes are to save weight and accommodate future payloads. It will also hold all the other elements together such as the spacecraft’s thrusters, water tanks, fuel tanks, gas tanks, electronics and wires.
The top bulkhead is thicker as it handles more loads. Orion’s storage tanks are supported from the top bulkhead which distributes the forces from 9 tonnes of propellant between the European Service Module structure and NASA structures such as the Crew Module Adapter and the launcher fairing, while the lower platform “only” provides support to prevent the tanks from swinging.

European Service Module (ESM)

Shipment of ESM-1 to the US is scheduled not earlier than March 2018 with a risk of further delays mainly because of delayed supplier deliveries. There are no margins in the ESM schedule so any problems in manufacturing, integration and test activities on the critical path may result in further delay. The critical path is driven by the high-pressure gas valves delivery from a US supplier but several other pieces of equipment are just behind them. The functional test model was delivered and accepted in May by NASA/Lockheed Martin.

European Service Module (ESM)

Shipment of ESM-1 to the US is scheduled not earlier than March 2018 with a risk of further delays mainly because of delayed supplier deliveries. There are no margins in the ESM schedule so any problems in manufacturing, integration and test activities on the critical path may result in further delay. The critical path is driven by the high-pressure gas valves delivery from a US supplier but several other pieces of equipment are just behind them. The functional test model was delivered and accepted in May by NASA/Lockheed Martin.

Yessir. Classic recipe for a scheduling disaster notwithstanding the statement about risk control. The latter is really management-talk for "we can't control it but we are trying".

Also interesting to read that the critical path is driven by a US supplier whereas earlier reports had indicated it was European suppliers causing the delays.

Multi-Purpose Crew Vehicle/European Service Modules (ESMs)

Shipment of ESM1 to the US is scheduled for April 2018 despite issues with supplier deliveries. The propulsion qualification test campaign was interrupted by the damage of the test article (two reaction control thrusters). The anomaly is being investigated and a recovery plan developed. There is no impact to the FM integration activity schedule.

A challenge to the delivery of equipment for ESM2 by dates committed to by the subcontractor is being resolved. NASA moved the ESM2 on-dock at Kennedy Space Center to September 2019.

The Phase-A for the design upgrades began on 1 September. The design consolidation review is planned for early 2018.

Studies to inform the identification of the Complementary Barter and the potential ESA contributions to the NASA Deep Space Gateway are continuing.

The struts you see prominently on the picture are ground tools installed only for transportation and handling.
They are needed because the ESM structure is so mass optimized that it cannot hold itself together without the other surrounding flight structures (cone adapter, crew module adapter).

More specifically the crew module adapter (CMA) and the outer shell panels. The Spacecraft Adapter (SA), also known as the cone adapter, is not needed for structural integrity of the ESM in 1G.

European skeleton for Orion

The structure for Europe’s second service module for NASA’s Orion spacecraft arrived at the Airbus clean room in Bremen, Germany, on 28 April.

Technicians started working on installing over 12 km of cables, fuel, water and air tanks, computers, engines and everything else that is needed to support astronauts further from Earth than any human being has been before.

The European Service Module is a crucial element of Orion, providing support to the crew module that will house up to four astronauts. The crew will travel over one million kilometres in total.

Wing span

The last time the solar wings of the European Service Module that will power the Orion spacecraft were featured, they were on a shaker table. They were exposed to launch vibrations and intense acoustic excitation at ESA’s Technical Centre in the Netherlands, to ensure they can survive the loud and shaky ride into space.

Having successfully passed these tests at ESA’s Technical Centre, the wings moved on to an Airbus’ clean room in Leiden, the Netherlands, for deployment testing. The solar wings are folded for launch but need to unfold once the Orion spacecraft is in space to start converting solar rays into electricity.

The fully deployed wings imaged here passed those tests as well, deploying in under two minutes, well within the 5 minute requirement. With the flick of a switch, thermal knives were energized, cutting through restrain cables to release the hold-downs in pairs.

ESA’s contribution to the Orion spacecraft provides power, propulsion, water, and air.

The first mission will take Orion around the Moon without astronauts and is scheduled for a 2019 launch. The solar panels will be folded inside the rocket fairing. Once released from NASA’s Space Launch System rocket they will unfold and rotate towards the Sun to start delivering power.

The solar wings are headed next to Bremen, Germany, where the wings will be integrated with the European service module. From there the service module is set to ship to the USA this summer for further tests and integration with the crew module adaptor.

Service module-1 main engine installation
 

An engine of the US Space Shuttle Orbital Manoeuvre System (OMS-E) was married with ESA’s European Service Module in Bremen, Germany.
 
This engine will provide the main thrust during Orion’s journey to the moon. It is one of 33 engines that were installed already.
 
Besides the OMS-E there are 8 auxiliary thrusters and 24 attitude control thrusters. The engine flew on 19 US Space Shuttle missions and is now ready for its last mission.
 
With this assembly all engines are now integrated into the Orion-ESM. The photo shows teams from Airbus, ArianeGroup and NASA during the integration of the engine.

Next major step in the big general picture is:
MLI blankets and MMOD panels followed by solar array wing and antennas integration (Similar but with differences to ATV).
Later:
Testing and then if the forward and aft adaptors are installed they can encapsulate the SM because fuelling and gasses and water is via the bottom. Then Orion Mate and full encapsulation.

I'm glad for the progress.  Hopefully between EM-1 and EM-2 both NASA and ESA will figure out how to streamline the process a little, especially since the big point for EM-1 is to test fly Orion/SLS.

You forgot several major steps that will happen first:
1. Ship the integrated module to the USA
2. Undo a good number of integration steps (basically: take the ESM partially apart again)
3. Make several modifications requested by NASA
4. Test modded systems and do more tests.
5. Re-integrate the ESM

Then comes your list.

Much like closing the bonnet on a car, with the radiators in place technicians can no longer access the internals of the European service module, symbolically ending the assembly and integration of the module that will fly further into our Solar System than any other human-rated spacecraft has ever flown before.

Coming to America: Orion’s European Service Module Arrives for First Mission


NASA is inviting media to its Kennedy Space Center in Florida at 9 a.m. EST Friday, Nov. 16, for an event marking the arrival from Bremen, Germany, of the European Service Module – the powerhouse that will supply NASA’s Orion spacecraft with electricity, propulsion, thermal control, air and water.

NASA Administrator Jim Bridenstine and ESA (European Space Agency) Director General Jan Wörner, as well as other senior leaders from NASA and ESA will discuss with media the international cooperation needed to send humans to the Moon and Mars. The event will air live on NASA Television and the agency’s website.

Following remarks, media will have the opportunity to speak with subject matter experts and tour Kennedy facilities until approximately 12:30 p.m. to get a glimpse of the work underway to prepare for the first launch of Orion and NASA’s Space Launch System, including Exploration Ground Systems.

Applications for U.S. media credentialing must be received by Friday, Nov. 9. Foreign national media must apply by Wednesday, Oct. 31. To submit an accreditation request, visit:

https://media.ksc.nasa.gov/

Media accreditation questions may be directed to Kennedy’s newsroom at 321-867-2468.

For the first time, NASA will use a European-built system as a critical element to power an American spacecraft, extending the international cooperation of the International Space Station into deep space. The European Service Module is a unique collaboration across space agencies and industry including ESA’s prime contractor, Airbus, and 10 European countries. The completion of service module work in Europe and shipment to Kennedy signifies a major milestone toward NASA’s human deep space exploration missions to the Moon and beyond.

At Kennedy, the service module will undergo integration with the Orion crew module, built by prime contractor Lockheed Martin, in preparation for Exploration Mission-1– a flight test farther into space than any human spacecraft has ventured.

European Service Module ready for shipment to the US

After years of planning, development, building and integration, the European Service module that will power the Orion spacecraft on its journey into lunar space is ready to be shipped. In November the fully integrated, tested, and sealed European workhorse will leave Bremen on an Antonov cargo plane for Kennedy Space Center in Florida, USA where it will be integrated with the rest of the Orion spacecraft.

ESA’s European service module will provide power, water, air and electricity to NASA’s Orion exploration spacecraft that will eventually fly beyond the Moon with astronauts. The European Service Module is now complete for Orion’s first mission that will do a lunar flyby without astronauts to demonstrate the spacecraft’s capabilities.

Orion’s solar wings will be shipped separately, also from Bremen. In the USA the module will be stacked together with NASA’s Crew Module Adaptor and Crew Module, the first time the complete spacecraft will be on display.

More tests await the Orion spacecraft at NASA’s Plum Brook facility where it will be put in the world’s largest vacuum chamber to simulate spaceflight as well as being subjected to acoustic tests to simulate the intense vibrations Orion will endure when launched on the world’s largest rocket, NASA’s Space Launch Systems.

This is a proud moment for Europe. For the first time, NASA will use a European-built system as a critical element to power an American spacecraft, extending the international cooperation of the International Space Station into deep space.

Work is already under way on the second European Service Module. The structure is complete and over 11 km of cables are being meticulously placed in preparation for the computers and equipment that will keep astronauts alive and well for the second Orion mission called Exploration Mission-2.

Human spaceflight, some consider the ultimate test. There is only one chance to do it right, no room for error. To prepare for this challenge, we expose the system to the same environments as they would be exposed to in flight. This approach of ‘Test Like You Fly’ is critical to the safety and success of Orion. Come to learn about Orion and the testing campaign to prove out the safest system for human spaceflight.

A New Round of Propulsion Tests for Orion
Posted on 18 Dec 2018 by julien

Earlier this month the same type of engine that will power Orion’s first mission around the Moon was fired up again and put to further tests at NASA’s White Sands facility in New Mexico, USA with the Propulsion Qualification Model, a replica of the flight model’s propulsion subsystem.

The propulsion subsystems  must be tested and qualified on Earth before it is considered fit to fly. Its main engine, the so-called OMS-E, is a refurbishment from the Shuttle programme that last flew in 2011. The video shows the engine being put through its paces in vacuum to ensure it works without atmosphere and the interaction with the rest of the subsystem is as predicted. The engine tested is not the engine that will fly to space on Exploration Mission-1, that engine is already at NASA’s Kennedy Space Center ready to integrate with the European Service Module.

Three more firings were done on 4 and 5 December for so-called delta-qualifications. As the engine was designed and used for the Space Shuttle, engineers must ensure that the engine will work as needed on the Orion spacecraft that has different requirements and is being launched on a different rocket.

The focus on these firing tests is the interaction between the engines and the propulsion subsystem as well as the performance of the pressurisation function. The propellant for the Qualification Model is provided by four 2000-liter tanks with 1-cm thick walls containing mixed oxides of nitrogen (MON) as oxidiser and monomethyl hydrazine (MMH) as fuel. The tanks will hold the propellant at a pressure of 25 bar with a total capacity of nine tonnes. The pressurisation system features high-pressure Helium tanks to push propellant into the engines.

The Propulsion Qualification Model (PQM) is a replica of the propulsion subsystem and is crucial for ensuring that all engines and thrusters fire safely and accurately to get the spacecraft where it needs to go. The OSM-E engine is one of 21 engines divided into three classes on the PQM: the primary Orbital Maneuvering System Engine (OMS-E), eight secondary auxiliary thrusters, and 12 reaction control system (RCS) thrusters. The Orion spacecraft will have 33 engines in total, double the amount of RCS thrusters than are included in the PQM.

The test team consists of around thirty people from Airbus, ESA, Lockheed Martin and NASA.

Final pieces arrive to complete assembly of Orion spacecraft
Posted on 29 Mar 2019 by julien   

Last week saw the arrival of the Solar Array Wings at NASA’s Kennedy Space Center in Florida, USA, the last major parts from Europe to complete the integration of the European Service Module.

Orion will have four solar wings measuring 7 m in total. The solar wings were shipped from an Airbus facility in Leiden, The Netherlands by aircraft to Miami airport and on to the Kennedy Space Center.

Since our last update (http://blogs.esa.int/orion/2019/02/25/s-band-radio-solar-array-drive-and-sun-sensor-testing/) the European Service Module has undergone functional propulsion tests. The “functional” aspect means that the avionics and software were tested without actually firing up the engines. Thermal cycling test, including various functional tests, will start this week.

The nozzle of the main OMS-E engine is being installed at the end of March and its movement tested during the gimbal test a few weeks later. The Solar Array Wings will be installed around the same time.

With everything installed, the European Service Module and Crew Module Adapter will go for a direct-field acoustic testing (D-FAT) session where it will be subjected to the extreme noises of a simulated rocket launch. Every rocket that lifts a spacecraft into orbit produces vibrations and loud noise that will shake the spacecraft. The D-FAT is a more mobile version of the larger acoustic chambers that are used to check spacecraft will survive a launch. In essence the European Service Module will be surrounded by large speakers and technicians will turn up the volume to the sound levels that occur at launch. The Service Module Test Article already underwent this type of D-FAT test and the more traditional acoustic test in the chamber at NASA’s dedicated facility at Plumbrook in Ohio, USA, in 2016.

Second module in production in Bremen

As work continues at a fast pace in the USA, the second European Service Module is already being assembled in the Airbus integration hall in Bremen, Germany. The first parts of the Thermal Control System and Consumable Storage System are being installed, mainly the subassemblies and cold plates for the radiators. These parts will provide a safe and cozy temperature for the astronauts as well as air to breathe and water to drink.

In parallel the thruster frames are being installed for the Reaction Control System and the auxiliary thrusters. Besides its main engine the Orion spacecraft uses 24 smaller thrusters for attitude control grouped in six pods of four, as well as eight auxiliary thrusters.

White Sands

Over in New Mexico, USA, the Propulsion Qualification Model is gearing up for another series of thruster firing tests. This test model is used to ensure the engines fire as needed and test the system as they are “hot-fired”. The main engine and auxiliary engines (http://blogs.esa.int/orion/2018/12/18/a-new-round-of-propulsion-tests-for-orion/) have been tested and in April the Reaction Control Systems will be fired up.

From the GAO report.

The European Space Agency delivered the European service module later than planned when the Orion program set its schedule baseline, and program officials stated that some of the delays leading right up to delivery resulted from failures during propulsion system testing as well as redesign of some power system components.
