SLS Booster Fired up to Test Improved Design for Future Artemis Missions

NASA engineers successfully completed a 24-inch diameter subscale solid rocket test on Dec. 2, 2021, at NASA’s Marshall Space Flight Center in Huntsville, Alabama, in the East Test Area. The sub-scale motor produced 76,400 pounds of thrust during the hot fire test. This test was the first of two tests supporting the Booster Obsolescence and Life Extension (BOLE) development effort that includes a new motor design for upcoming Artemis missions after Artemis VIII. This 334-inch motor was the longest subscale motor tested to date.

Artemis IV Liquid Oxygen Tank Aft Barrel Moves to Next Phase of Production

Move crews at NASA’s Michoud Assembly Facility lift the aft liquid oxygen tank (LOX) barrel out of the Vertical Weld Center (VWC) for its next phase of production. The aft barrel will eventually be mated with the forward barrel and the forward and aft domes to form the LOX tank, which will be used in the Space Launch System’s (SLS) Artemis IV mission. The LOX tank holds 196,000 gallons of super-cooled liquid oxygen to help fuel four RS-25 engines. The SLS core stage is made up of five unique elements: the forward skirt, liquid oxygen tank, intertank, liquid hydrogen tank, and the engine section. The liquid oxygen hardware, along with the liquid hydrogen tank will provide propellant to the four RS-25 engines to produce more than two million pounds of thrust to help launch NASA’s Orion spacecraft, astronauts, and supplies beyond Earth’s orbit to the Moon. Together with its four RS-25 engines, the rocket’s massive 212-foot-tall core stage — the largest stage NASA has ever built — and its twin solid rocket boosters will produce 8.8 million pounds of thrust to send NASA’s Orion spacecraft, astronauts, and supplies beyond Earth’s orbit to the Moon and, ultimately, Mars. Offering more payload mass, volume capability and energy to speed missions through space, the SLS rocket, along with NASA’s Gateway in lunar orbit, the Human Landing System, and Orion spacecraft, is part of NASA’s backbone for deep space exploration and the Artemis lunar program. No other rocket is capable of carrying astronauts in Orion around the Moon in a single mission. Photographed on Tuesday, May 10, 2022.

NASA, Northrop Grumman to Test Fire Future Artemis Booster Motor
NASA and Northrop Grumman will perform a full-scale static test of a  Space Launch System (SLS) solid rocket booster motor at Northrop Grumman’s Promontory, Utah, test facility July 21. Engineers will fire the booster during the demonstration, called the Flight Support Booster 2 test, to evaluate materials and processes to improve boosters for future Artemis missions.


“The current SLS boosters for the first eight Artemis missions are using a robust mix of new avionics and substantial heritage hardware from the Space Shuttle Program,” said Bruce Tiller, SLS Booster Program manager. “This particular ground test will demonstrate some new materials, a completely new steering system, and a new way to ignite the motor.  Data from this test will improve our booster design for future missions that take us farther into deep space than ever before.”


For the test, one booster is affixed in a horizontal test stand and fired for approximately two minutes, the same amount of time and at the same power level as it would be fired during launch. On launch day, a pair of solid rocket boosters in a vertical position attached to the core stage of the SLS rocket supply more than 75% of the total thrust for the first two minutes of flight. Northrop Grumman is the lead contractor for the SLS solid rocket boosters.


NASA and Northrop Grumman experts will discuss the Flight Support Booster 2 test during a Facebook Live on the Space Launch System rocket’s Facebook page, as well as on NASA’s Marshall Space Flight Center YouTube channel, beginning at 2:55 p.m. EDT.  During the test, anyone can submit questions on Twitter, Facebook, and YouTube using the hashtag #AskNASA. Julia Khodabandeh, motor team lead for SLS boosters at NASA’s Marshall Space Flight Center in Huntsville, Alabama, and Jessica Rose, chemical engineer for SLS boosters at Northrop Grumman, will answer questions.

NASA and Northrop Grumman, the Space Launch System (SLS) booster lead contractor, will conduct the full-scale Flight Support Booster-2 (FSB-2) test in Promontory, Utah, on July 21 to support future flights of NASA’s mega Moon rocket. The SLS uses two, five-segment solid rocket boosters to help launch NASA’s Artemis missions to the Moon. A single solid rocket booster motor will fire during the FSB-2 test and evaluate improvements and new materials in the boosters for missions beyond Artemis III. Through Artemis missions, NASA will land the first woman and the first person of color on the Moon, paving the way for a long-term lunar presence and serving as a steppingstone to send astronauts to Mars.


The FSB-2 test builds off the Flight Support Booster-1 test conducted in September 2020 and will demonstrate a newly qualified motor initiation system and qualify a new ablative lining to protect the booster nozzle. This test will also provide information for the development of the next generation booster obsolescence and life extension booster that will support Artemis IX and beyond.


Through Artemis missions, NASA will land the first woman and the first person of color on the Moon, paving the way for a long-term, sustainable lunar presence and serving as a steppingstone for future astronaut missions to Mars.

Philip toured MAF and interviewed SLS Boeing folk, so here's an article from him, extensive as usual. Photos are his, but he took A LOT. Will be a full dump in L2 later. Epic to see MAF in this detail after the last major MAF photo dump during Shuttle.

NASA Telescope, Moon Rocket Named TIME Inventions of 2022

NASA’s James Webb Space Telescope and Space Launch System (SLS) rocket were named 2022 TIME Inventions of the Year. NASA led the international Webb partnership with ESA (European Space Agency) and CSA (Canadian Space Agency). The agency’s SLS rocket, the world’s most powerful rocket, is designed to send humans to the Moon on Artemis missions for the benefit of humanity. TIME made the announcement Thursday, Nov. 10.

“We designed the Webb observatory to see the first lights that turned on in our universe.  When I saw the first images released, I was struck with awe, wonder, and the satisfaction of knowing that whatever is out there, Webb will see it,” said Mike Menzel, NASA mission systems engineer for Webb at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. TIME named Webb a Best Invention in the “Design” category.

The SLS rocket is planned to launch on its first flight test for the Artemis I mission, Wednesday, Nov. 16, to send an uncrewed Orion spacecraft around the Moon and back to Earth to thoroughly test systems before missions with astronauts. SLS is the only rocket capable of launching humans in Orion along with their supplies to the Moon and beyond. TIME named SLS a Best Invention in the “Experimental” category.

“We will demonstrate the capability of the Space Launch System Moon rocket, the largest rocket NASA has built since the Saturn V, on the Artemis I mission,” said John Honeycutt, SLS program manager at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “The heavy-lift rocket’s innovative design allows it to evolve and become even more powerful so that it can carry both astronauts and large cargos on increasingly more complex missions to the Moon and Mars.”

Launched Dec. 25, 2021, from French Guiana, the Webb telescope has already been uncovering previously unseen views and hidden secrets of the universe. Webb has seen early galaxies, provided a new look at planets in our own solar system, and peered through dusty clouds to see stars forming, such as in the Pillars of Creation.

NASA Headquarters, Washington oversees the Webb telescope mission. NASA Goddard manages Webb for the agency and oversees work on the mission performed by the Space Telescope Science Institute, Northrop Grumman, and other mission partners. In addition to Goddard, several NASA centers contributed to the project, including the agency’s Johnson Space Center in Houston, Jet Propulsion Laboratory in southern California, Marshall Space Flight Center in Huntsville, Alabama, Ames Research Center in California’s Silicon Valley, and others.

With its unprecedented power and capabilities, the SLS rocket provides the foundation for NASA’s Artemis missions to the Moon. SLS makes it possible to launch the Orion spacecraft, which is built in partnership with ESA, on missions to the Moon that will provide the knowledge for humans to travel to Mars. SLS is built with a combination of proven systems and innovative manufacturing. To fulfill America’s future needs for deep space missions, SLS will evolve into increasingly more powerful configurations.

SLS is America’s rocket and more than 1,000 companies in 45 states contributed to the rocket managed by Marshall, which oversees the work by lead contractors Boeing, Notrthrop Grumman, Aerojet Rocketdyne and other companies. Currently, NASA and its industry partners are in the process of building rockets for four more Artemis missions. All NASA Centers have played a role in the Artemis missions, which are launching a new era of human deep space exploration.

"Zietsman also confirmed that communication with the Core Stage was maintained throughout the anticipated flight envelope, including the beginning phases of its planned, destructive reentry near the Hawaiian islands for safe disposal in the Pacific Ocean."

Do we have a map or know the more or less precise location of re-entry?

NASA Advances Artemis Moon Rocket Production for Future Missions



As the SLS program transitions from rocket development efforts to operations, NASA and Boeing evaluated how to improve upon the time required to produce each core stage and best use space at Michoud.


 “We’re making progress developing, manufacturing, and assembling elements for future Artemis missions,” said Jim Free, associate administrator for the Exploration Systems Development Mission Directorate. “Our collective workforce across NASA centers and industry partners plays a key role in accomplishing NASA’s long-term plans for exploring the Moon.”


Beginning with production for Artemis III, NASA and Boeing will use Michoud, where the SLS core stages are currently manufactured, to produce and outfit the core stage elements, and available space at Kennedy for final assembly and integration. This opportunity provides for multiple mission elements to be manufactured and outfitted at the same time and for the workforce at Michoud to begin building the rocket’s exploration upper stage, which will enable SLS to send even heavier and larger cargo to the Moon on the same missions with astronauts beginning with Artemis IV.


All five major core stage structures will be manufactured at Michoud using current robotic welding tools and fixtures and complete all thermal protection system spray applications at Michoud. There, the forward skirt, the intertank, liquid oxygen tank, and the liquid hydrogen will continue to be outfitted and joined to form the upper part of the core stage. Upon completion, these structures, which comprise the top four-fifths of the 212-foot-tall stage, will be shipped to Kennedy’s Vehicle Assembly Building (VAB) where they will be joined and vertically integrated in High Bay 2.


Once the engine section structure is manufactured, it will be transported to Kennedy’s Space Station Processing Facility for outfitting in the facility. When the engine section is completely outfitted, it and the stage’s four RS-25 engines will be moved to the VAB’s High Bay 2 for integration with the rest of the core stage, where technicians can more easily move it for stacking and assembly operations.


Four of five major core stage parts for Artemis II have been joined, and teams are outfitting the last part, the engine section, and will soon connect it and the RS-25 engines to complete the stage at Michoud. The Artemis II stage is scheduled to be completed and delivered to Kennedy in 2023. The engine section for the Artemis III SLS core stage is expected to arrive at Kennedy in mid-December.


With Artemis, NASA will land the first woman and the first person of color on the lunar surface and establish long-term exploration at the Moon in preparation for human missions to Mars. SLS and NASA’s Orion spacecraft, along with the commercial human landing system and the Gateway in orbit around the Moon, are NASA’s backbone for deep space exploration.

[...]

Do I even ... understand this correctly? They currently have an up-and-running core stage assembly line in Michoud, and the plan is to start taking sub-assemblies off that line and ship them to Kennedy, where (presumably duplicate) tooling will be used for final assembly? And this is better somehow?

Ahhh, here it is.  I knew this news (which I heard about via NSF retweet of Gavin) had to be posted here in NSF's forums already, I just couldn't find it.  Over in the HSF-to-Moon section there are threads for the Artemis 3 Orion and for the Artemis 3 Service Module, but none for Artemis 3 SLS / Core Stage.  Shouldn't there be, or does all Artemis 3 SLS / Core Stage content go into this thread here?  If so, can you link to this thread here in the first post of those two Artemis 3 threads?  I'm just trying to think of a way to help others find this thread, as it took me over 10 minutes, including site-limited googling.

Aaaanyway, I have a similar comment about this news, but will take it to the discussion thread. https://forum.nasaspaceflight.com/index.php?topic=57014.900
