Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA completed a full duration, 650-second hot fire of the RS-25 certification engine Nov. 29, continuing a critical test series to support future SLS (Space Launch System) missions to deep space as NASA explores the secrets of the universe for the benefit of all.

Danny Nowlin NASA completed a full duration, 650-second hot fire of the RS-25 certification engine Nov. 29, continuing a critical test series to support future SLS (Space Launch System) missions to deep space as NASA explores the secrets of the universe for the benefit of all. Danny Nowlin NASA conducted the third RS-25 engine hot fire in a critical 12-test certification series Nov. 29, demonstrating a key capability necessary for flight of the SLS (Space Launch System) rocket during Artemis missions to the Moon and beyond.
NASA is conducting the series of tests to certify new manufacturing processes for producing RS-25 engines for future deep space missions, beginning with Artemis V. Aerojet Rocketdyne, an L3Harris Technologies Company and lead engines contractor for the SLS rocket, is incorporating new manufacturing techniques and processes, such as 3D printing, in production of new RS-25 engines.
Crews gimbaled, or pivoted, the RS-25 engine around a central point during the almost 11-minute (650 seconds) hot fire on the Fred Haise Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. The gimbaling technique is used to control and stabilize SLS as it reaches orbit.
During the Nov. 29 test, operators also pushed the engine beyond any parameters it might experience during flight to provide a margin of operational safety. The 650-second test exceeded the 500 seconds RS-25 engines must operate to help power SLS to space. The RS-25 engine also was fired to 113% power level, exceeding the 111% level needed to lift SLS to orbit.
The ongoing series will stretch into 2024 as NASA continues its mission to return humans to the lunar surface to establish a long-term presence for scientific discovery and to prepare for human missions to Mars.
Four RS-25 engines fire simultaneously to generate a combined 1.6 million pounds of thrust at launch and 2 million pounds of thrust during ascent to help power each SLS flight. NASA and Aerojet Rocketdyne modified 16 holdover space shuttle main engines, all proven flightworthy at NASA Stennis, for Artemis missions I through IV.
Every new RS-25 engine that will help power SLS also will be tested at NASA Stennis. RS-25 tests at the site are conducted by a combined team of NASA, Aerojet Rocketdyne, and Syncom Space Services operators. Syncom Space Services is the prime contractor for Stennis facilities and operations.

NASA/Charles Beason Artemis II NASA astronauts Victor Glover, Reid Wiseman, and Christina Koch of NASA, and CSA (Canadian Space Agency) astronaut Jeremy Hansen signed the Orion stage adapter for the SLS (Space Launch System) rocket at NASA’s Marshall Space Flight Center in Huntsville, Alabama, Nov. 27. The hardware is the topmost portion of the SLS rocket that they will launch atop during Artemis II when the four astronauts inside NASA’s Orion spacecraft will venture around the Moon.

The Orion stage adapter is a small ring structure that connects NASA’s Orion spacecraft to the SLS rocket’s interim cryogenic propulsion stage and fully manufactured at Marshall. At five feet tall and weighing 1,800 pounds, the adapter is the smallest major element of the SLS rocket. During Artemis II, the adapter’s diaphragm will serve as a barrier to prevent gases created during launch from entering the spacecraft.
NASA is working to land the first woman and first person of color on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single mission. Through Artemis, NASA will explore more of the lunar surface than ever before and prepare for the next giant leap: sending astronauts to Mars.

(Oct. 4, 2023) — The Roscosmos Progress 84 cargo craft is pictured docked to the International Space Station’s Poisk module.NASA NASA will provide live launch and docking coverage of the Roscosmos Progress 86 cargo spacecraft carrying about three tons of food, fuel, and supplies for the Expedition 70 crew aboard the International Space Station.
The unpiloted spacecraft is scheduled to launch at 4:25 a.m. EST on Friday, Dec. 1 (2:25 p.m. Baikonur time), on a Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan.
NASA coverage will begin at 4 a.m. on the NASA+ streaming service via the web or the NASA app. Coverage also will air live on NASA Television, YouTube, and on the agency’s website. Learn how to stream NASA TV through a variety of platforms including social media.
The Progress spacecraft will be placed into a two-day, 34-orbit journey to the station, leading to an automatic docking to the Poisk module at 6:14 a.m. Sunday, Dec. 3. Coverage of rendezvous and docking will begin at 5:30 a.m. on NASA Television and the agency’s website.
The spacecraft will remain at the orbiting laboratory for approximately six months, then undock for a destructive but safe re-entry into Earth’s atmosphere to dispose of trash loaded by the crew.
The International Space Station is a convergence of science, technology, and human innovation that enables research not possible on Earth. For more than 23 years, NASA has supported a continuous U.S. human presence aboard the orbiting laboratory, through which humans have learned to live and work in space for extended periods of time. The space station is a springboard for the development of commercial destinations in space and a low Earth orbit economy, as well as NASA’s next great leaps in exploration, including Artemis missions to the Moon and eventually Mars.

Record-breaking NASA astronaut Frank Rubio provides the first Spanish-language video tour of humanity’s home in space – the International Space Station.
Rubio welcomes the public aboard the microgravity science laboratory in a behind-the-scenes look at living and working in space recorded during his 371-day mission aboard the space station, the longest single spaceflight in history by an American.
The station tour is available to watch on the agency’s NASA+ streaming platform, NASA app, NASA Television, YouTube, and the agency’s website.
Continuously inhabited for more than 23 years, the space station is a scientific platform where crew members conduct experiments across multiple disciplines of research, including Earth and space science, biology, human physiology, physical sciences, and technology demonstrations that could not be performed on Earth.
The crew living aboard the station are the hands of thousands of researchers on the ground conducting more than 3,300 experiments in microgravity. During his record-breaking mission, Rubio spent many hours contributing to scientific activities aboard the orbiting laboratory, conducting everything from human health studies to plant research.
Rubio returned to Earth in September, having completed approximately 5,936 orbits of the Earth and a journey of more than 157 million miles during his first spaceflight, roughly the equivalent of 328 trips to the Moon and back.
