Have they mentioned when EM-1 is scheduled?
Visual note that the arrays will be like ATV, as we know - but important to note. Not shown in this graphic.
Gerst is stepping carefully around a Q about his confidence in this ESA collaboration for Orion. A very odd answer.
Hmmm, Gerst just seemed to imply that EM-1 would be unmanned? Has this always been the case? Or perhaps I misunderstand.
They've had years and years on this vehicle, and it was too heavy for Ares 1. Now it's currently too heavy for EM-2 on SLS?
Quote from: Chris Bergin on 01/16/2013 04:18 pmThey've had years and years on this vehicle, and it was too heavy for Ares 1. Now it's currently too heavy for EM-2 on SLS?It's not too heavy for SLS, the primary problem is the parachute load, AFAIK.
Main engine (OME), and some other elements like network cards will be from NASA for integration.Still a bit shocked by Mark's almost defeatist answer on Orion mass. "Got to be aggressive. It's not easy."
ESA budget number questions at the moment.
More notes that they really are only concentrating on EM-1 and EM-2 - with spares for EM-2.No agreement with ESA with missions past EM-2.
Mass is a problem for EM2 but not for EM1?

in the video, Orion is not airlifted by a helicopter after splashdown. It is recovered in the bay of an amphibious Naval vessel. The astronauts have already disembarked to one of the boats or a helicopter, yes?How were the Apollo capsules recovered? If by helicopter, then perhaps Orion is too heavy to be airlifted?I vaguely recall a Roger Moore Bond film where a deep sea capsule, with a nice bed inside, is recovered by a ship in a similar fashion as this video.Oh, and is that another Orion capsule already in the bay? Or a stand to put the Orion on to for stowage?
Sadly, I think this announcement is a significant nail in the coffin of Orion. (not the first) I am doubtful that EM-1 will ever fly.

[EFT-1 Orion will] use doublers over the small cracks
At the start of the presentation, Mr. Gerstenmaier said that the Europeans would develop the first Service Module and portions of the second Service Module.Portions?
After having been around for the NASA moon missions as a youngster, I was hoping that this press event would be the opening salvo toward BEO exploration. Reading some of the reports as to the weight issue with Orion, I am deeply saddened. Of course, the space program is not about me or my dreams. Here's hoping that NASA can come up with something to remedy this situation.

Here's hoping that NASA can come up with something to remedy this situation.I don't know, but to me the weight issue doesn't seem like a big problem. EFT-1 will fly as scheduled as well as EM-1. EM-2 isn't scheduled until 2021, 7 years after the first test flight of EFT-1 which should provide most of the information they need to shed the excess weight. Just my opinion of course.
OK, so ESA will develop and build all of the EM-1 and EM-2 SMs, but portions of the EM-2 SM will be developed and built where left-over spare parts from the EM-1 SM aren't available. I think I've got that.
To push Orion through space, NASA will supply the ATV service module with an extra engine, none other than a recycled Space Shuttle thruster. This engine will supply around 26 kN of thrust in addition to eight smaller engines as backup. The smaller engines will supply a total of 490 N, enough to get Orion back to Earth.Attitude control will be done by yet more thrusters for which the design needs to be finalised, but think in terms of 20+ small engines working together.Although ATV’s solar panel configuration will remain, ESA will give them a significant upgrade. Slightly shorter but wider, Orion’s solar panels will use Gallium Arsenide technology and supply more electricity, up to 11 kW, or enough to power the energy needs of a typical household. These newer solar panels offer 30% efficiency converting solar energy; ATV’s current solar panels only manage around 17%.

Apollo was recovered the same way. Crew via helicopter, CM by crane onto the ship. CM was too heavy to be lifted by helicopter.

Yes, still a publicity invention to invoke Saturn V.BTW, that video (nice BTW) does highlight the incredible complexity of the parachute system... Here are the steps1) Drogues2) Bigger Drogues3) Tiny drogues to pull out...4) ... The main parachutes.Wow, four different drogue/chute systems!?!? At some point with that many systems you are just increasing the odds of a part failing instead of increasing robustness.

I find it strange that they keep insisting on rending Orion "upside down". (Yeah, I know, there is no "up" in space... but I'm thinking of the Astronaut orientation inside)
Guys,don't you think there is something missing in these models?The antennas! I do not think low gain antennas are sufficient for the data rates and distances that they will have.So I would think a combination of LGAs plus at leat one high gain antenna is needed.Any opinion?

That would not seem to be particularly worth mentioning, and, in any case, it really isn't NASA's business how ESA chooses to build the service modules as long as they meet specifications and schedule.
I understood that the agreement only covered EM-1 and a portion of EM-2 (because of the EM-1 left over parts that will be incorporated in EM-2).

SmithPosted: 16-Jan-2013Updated: 17-Jan-2013 12:00 AMNASA and the European Space Agency (ESA) provided more details today of their agreement for ESA to provide the service module for NASA's Orion spacecraft.<snip>Under this new agreement, ESA will compensate NASA for future common systems operating costs by using ATV hardware for the service module for one of NASA's Orion spacecraft. The service module provides electrical power, propulsion and storage for consumables. <snip>The agreement is for ESA to provide some of the service module systems for the 2017 flight. It will also provide spare parts. If the spare parts are not required, they will be used for the 2021 flight. That is the extent of the agreement at this point. NASA will be provided with the intellectual property to enable U.S. companies to build whatever systems are needed for Orion service modules after that.<snip>
The agreement can be renewed in exchange for ESA astronauts, etc.
Quote from: yg1968 on 01/19/2013 03:34 amThe agreement can be renewed in exchange for ESA astronauts, etc. Of course it can. But as the current agreement is only for two SM's, the "safety" of international cooperation ends after that. They can renew/extend the agreement but do not have to. ESA can bail out, no hard feelings. NASA can cancel Orion, no hard feelings. That's my point.
This is only the first step. Just wait, there will be more announcements like this.

I'm curious Clongton about your opinions regarding the ESA SM and the fact that NASA will be providing all of the fairings and other load bearing structures for it. NASA will also have, according to the presser, all the information from the SM should they want to create it themselves.

Meditating on SM-1 and portions of SM-2 just now, the obvious occurred to me: EM-1 and EM-2 are very different missions. In particular, EM-2 will have a crew and EM-1 won't and therefore SM-1 will not need to have functioning ECLSS-related equipment, whereas SM-2 will. So perhaps ESA will deliver SM-1 with a mass mock-up of the ECLSS stuff and SM-2 will have real ECLSS (and perhaps other mission-specific equipment) added by NASA?Just a thought.
For example if it fails to provide a required burn and the Orion spacecraft is stranded, and cannot return to Earth. Will ESA then be required to provide a second SM?

http://www.thespacereview.com/article/2222/1The benefits (and limitations) of space partnershipsby Jeff FoustMonday, January 21, 2013<snip>[The ESA/NASA service module] cooperation, though, has its limitations. One aspect not immediately clear from the agency announcements about the agreement is that it covers only one service module. That module will be flown on the EM-1 mission, the first Orion/SLS mission planned for launch in 2017. Production of service modules for later missions, including the first crewed Orion mission, EM-2 in 2021, remains undecided.ESA will provide spare parts for the EM-1 module that could be used for later missions, said NASA Orion program manager Mark Geyer. However, Gerstenmaier said no decision has been made on who will produce the service module for the EM-2 and later missions, raising the possibility that the component could revert back to NASA.“We really haven’t defined that at this point,” Gerstenmaier said. “We’re protected both ways.” That includes maintaining ownership of the relevant intellectual property regarding the service module so that NASA could manufacture future modules if needed. “We’ve really made no decisions about those future flights. We think it’s important to set this up on the first flight and then plan for that transition” for the second and future flights.<snip>

The only possible competition would be if the ATV-derived SM is only an interim design and, after EM-2, will be directly evaluated against the LM unit to see what will be the 'production' model used.
