Topic: Liquid Hydrogen
Green Run is a demanding series of eight tests and nearly 30 firsts: first loading of the propellant tanks, first flow through the propellant feed systems, first firing of all four engines, and first exposure of the stage to the vibrations and temperatures of launch. ![]() The Space Launch System (SLS) rocket is completing the Green Run test for the rocket’s core stage, shown installed on the top left side of the B-2 Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. For Green Run, the team is completing a series of eight tests culminating with Test 8, a full-up hot fire test that lasts eight minutes. Flames from the test will exit out of the yellow flame bucket shown here on the north side of the test stand. (NASA/Stennis) «Read the rest of this article» Sections: Technology | No Comments
NASA’s Artemis Lunar Program moves full speed ahead
Through America’s Moon to Mars exploration approach, Artemis gained bipartisan support this year among members of Congress, the U.S aerospace industry, as well as with international partners, including Canada, Australia, and Japan, and member states of the European Space Agency. «Read the rest of this article» Sections: Technology | No Comments
NASA to test World’s Largest Rocket Fuel Tank
Earlier this year, a NASA and Boeing test team subjected a test version of the Space Launch System (SLS) liquid hydrogen tank to a series of 37 tests that simulate liftoff and flight stresses by using large hydraulic pistons to push and pull on the test tank with millions of pounds of force. ![]() Engineers are preparing to push a test article identical to the world’s largest rocket fuel tank beyond its design limits and find its breaking point during upcoming tests at NASA’s Marshall Space Flight Center in Huntsville, Alabama. This will be the largest-ever controlled test-to-failure of a NASA rocket stage fuel tank. (NASA/MSFC) «Read the rest of this article» Sections: Technology | No Comments
NASA to order additional SLS Rocket Stages for Future Artemis Missions
The agency intends to work with Boeing, the current lead contractor for the core stages of the rockets that will fly on the first two Artemis missions, for the production of SLS rockets through the next decade. ![]() NASA finished assembling the main structural components for the Space Launch System (SLS) rocket core stage on Sept. 19. Engineers at NASA’s Michoud Assembly Facility in New Orleans fully integrated the last piece of the 212-foot-tall core stage by adding the engine section to the rest of the previously assembled structure.

NASA assembles final section of Space Launch System Rocket Stage
Engineers at the agency’s Michoud Assembly Facility in New Orleans connected the last of the five sections of the Space Launch System (SLS) rocket core stage on September 19th. The stage will produce 2 million pounds of thrust to send Artemis I, the first flight of SLS and NASA’s Orion spacecraft to the Moon. ![]() NASA finished assembling the main structural components for the Space Launch System (SLS) rocket core stage on Sept. 19.

NASA’s race back to the Moon helped along by Michigan
Futuramic, a company with factories in Detroit and Warren, is one of more than 78 Michigan companies and 3,200 businesses across 50 states supporting NASA’s return to the Moon by supplying parts for the agency’s new deep space rocket, Space Launch System (SLS), the Orion spacecraft and Exploration Ground Systems. Through NASA’s Artemis program, the agency will embark on a series of increasingly complex missions to establish a presence at the Moon for decades to come and learn the skills needed to send astronauts to Mars. ![]() Technicians prepare the passive roller tool built by Futuramic in Warren, Michigan, to transport the massive liquid hydrogen fuel tank for NASA’s new deep space rocket, the Space Launch System (SLS), so that it can be joined to the top part of the core stage. The tool is enabling the construction of the rocket’s core stage that will be provide 2 million pounds of thrust to launch the Artemis-1 mission beyond the Moon.

NASA’s Plans for traveling to the Moon Coming TogetherNASA Headquarters
Building on progress in 2018, most of the major manufacturing for the first mission is complete, and this year, teams will focus on final assembly, integration, and testing, as well as early work for future missions. «Read the rest of this article» Sections: Technology | No Comments
NASA to test Space Launch System’s Largest Fuel TankWritten by Tracy McMahan
The stand is critical for ensuring SLS’s liquid hydrogen tank can withstand the extreme forces of launch and ascent on its first flight, and later on the second flight, which will carry up to four astronauts in the Orion spacecraft on a journey around the moon, into the deep-space proving ground for the technology needed for the journey to Mars. ![]() Robert Bobo, left, and Mike Nichols talk beneath the 221-foot-tall Test Stand 4693, the largest of two new Space Launch System test stands at NASA’s Marshall Space Flight Center in Huntsville, Alabama. Bobo manages SLS structural strength testing, and Nichols is lead test engineer for the SLS liquid hydrogen tank, which the stand will subject to the forces it must endure during launch and flight.

NASA Building Space Launch System’s Core Stage Piece by PieceNASA’s Marshall Space Flight Center
Why is NASA building the world’s most powerful rocket? Because SLS is ready to support both near-term missions in the proving ground around the moon starting in 2018, while at the same time being capable of carrying the very large hardware like landers, habitats and other supplies and equipment needed to explore Mars and other deep space destinations in the 2030s and beyond. ![]() Engineers just completed welding the liquid hydrogen tank that will provide fuel for the first SLS flight in 2018. The tank measures more than 130 feet tall, comprises almost two-thirds of the core stage and holds 537,000 gallons of liquid hydrogen — which is cooled to minus 423 degrees Fahrenheit.
