First NASA Artemis Rocket Core Stage Loaded on Pegasus Barge

The first Artemis rocket stage is guided toward NASA’s Pegasus barge Jan. 8 ahead of its forthcoming journey to NASA’s Stennis Space Center near Bay St. Louis, Mississippi. Teams rolled out, or moved, the completed core stage for NASA’s Space Launch System (SLS) rocket from NASA’s Michoud Assembly Facility in New Orleans to the barge in preparation for the core stage Green Run test series. Pegasus, which was modified to ferry SLS rocket hardware, will transport the core stage more than 40 miles from Michoud to Stennis for the comprehensive core stage Green Run test series. Green Run, named for its testing of new, or green, hardware progressively, is the final test campaign ahead of the first Artemis launch. (Credits: NASA)

NEW ORLEANS (NASA PR) — The first Space Launch System (SLS) rocket core stage for NASA’s Artemis program completed manufacturing work at NASA’s Michoud Assembly Facility in New Orleans and was loaded onto the agency’s Pegasus barge on Jan. 8 for delivery to NASA’s Stennis Space Center near Bay St. Louis, Mississippi. With NASA Deputy Administrator Jim Morhard in attendance, NASA rolled out the core stage for the SLS rocket onto Pegasus in preparation for the Green Run test series, the final test campaign ahead of the agency’s first Artemis launch.

NEW ORLEANS (NASA PR) — Teams at NASA’s Michoud Assembly Facility in New Orleans moved the core stage, complete with all four RS-25 engines, for NASA’s Space Launch System (SLS) rocket to Building 110 for final shipping preparations on Jan. 1.

The SLS core stage includes state-of-the-art avionics, propulsion systems and two colossal propellant tanks that collectively hold 733,000 gallons of liquid oxygen and liquid hydrogen to power its four RS-25 engines.

The completed stage, which will provide more than 2 million pounds of thrust to help power the first Artemis mission to the Moon, will be shipped via the agency’s Pegasus barge from Michoud to NASA’s Stennis Space Center near Bay St. Louis, Mississippi, later this month.

Once at Stennis, the Artemis rocket stage will be loaded into the B-2 Test Stand for the core stage Green Run test series. The comprehensive test campaign will progressively bring the entire core stage, including its avionics and engines, to life for the first time to verify the stage is fit for flight ahead of the launch of Artemis I.

NASA is working to land the first woman and next man on the Moon by 2024. SLS is part of NASA’s backbone for deep space exploration, along with Orion and the Gateway in orbit around the Moon. SLS will be the most powerful rocket in the world and will send astronauts in the Orion spacecraft farther into space than ever before. No other rocket is capable of carrying astronauts in Orion around the Moon.

Artemis Program 2019 in Review

WASHINGTON (NASA PR) — Using a sustainable architecture and sophisticated hardware unlike any other, the first woman and the next man will set foot on the surface of the Moon by 2024. Artemis I, the first mission of our powerful Space Launch System (SLS) rocket and Orion spacecraft, is an important step in reaching that goal.

As we close out 2019 and look forward to 2020, here’s where we stand in the Artemis story — and what to expect in 2020.

NASA Faces Billions in Deferred Maintenance & Repairs

by Douglas Messier
Managing Editor

Although NASA has made some progress in repairing and rebuilding its aging infrastructure, the space agency faces a deferred maintenance backlog of $2.65 billion, according to a new report by the Office of Inspector General (IG).

NASA is one of the biggest managers of property in the federal government, with 5,000 buildings and structures in 14 states. More than 83 percent of the structures are beyond their original design life, the review found.

NASA Attaches First of 4 RS-25 Engines to Artemis I Rocket Stage

NEW ORLEANS (NASA PR) — Engineers and technicians at NASA’s Michoud Assembly Facility in New Orleans have structurally mated the first of four RS-25 engines to the core stage for NASA’s Space Launch System (SLS) rocket that will help power the first Artemis mission to the Moon.

Integration of the RS-25 engines to the recently completed core stage structure is a collaborative, multistep process for NASA and its partners Boeing, the core stage lead contractor, and Aerojet Rocketdyne, the RS-25 engines lead contractor. To complete the installation, the technicians will now integrate the propulsion and electrical systems. 

The installation process will be repeated for each of the four RS-25 engines. The four RS-25 engines used for Artemis I were delivered to Michoud from Aerojet Rocketdyne’s facility at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, in June.

The engines, located at the bottom of the core stage in a square pattern, are fueled by liquid hydrogen and liquid oxygen. During launch and flight, the four engines will fire nonstop for 8.5 minutes, emitting hot gases from each nozzle 13 times faster than the speed of sound. The completed core stage with all four engines attached will be the largest rocket stage NASA has built since the Saturn V stages for the Apollo Program.

NASA is working to land the first woman and next man on the Moon by 2024. SLS is part of NASA’s backbone for deep space exploration, along with Orion and the Gateway in orbit around the Moon. SLS is the only rocket that can send Orion, astronauts and supplies to the Moon on a single mission.

NASA Commits to Future Artemis Missions With More SLS Rocket Stages

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. Boeing technicians bolted the engine section to the stage’s liquid hydrogen propellant tank. (Credit: NASA/Steven Seipel)

WASHINGTON (NASA PR) — NASA has taken the next steps toward building Space Launch System (SLS) rocket core stages to support as many as 10 Artemis missions, including the mission that will carry the first woman and next man to the Moon by 2024.
