BAY ST. LOUIS, Miss. (NASA PR) — NASA conducted a hot fire Saturday of the core stage for the agency’s Space Launch System (SLS) rocket that will launch the Artemis I mission to the Moon. The hot fire is the final test of the Green Run series.
BAY ST. LOUIS, Miss. (NASA PR) — NASA is targeting a two-hour test window that opens at 5 p.m. EST Saturday, Jan. 16, for the hot fire test of NASA’s Space Launch System (SLS) rocket core stage at the agency’s Stennis Space Center near Bay St. Louis, Mississippi. Live coverage will begin at 4:20 p.m. on NASA Television and the agency’s website, followed by a post-test briefing approximately two hours after the test concludes.
The hot fire is the eighth and final test of the Green Run series to ensure the core stage of the SLS rocket is ready to launch Artemis missions to the Moon, beginning with Artemis I. The core stage includes the liquid hydrogen tank and liquid oxygen tank, four RS-25 engines, and the computers, electronics, and avionics that serve as the “brains” of the rocket. During the test, engineers will power up all the core stage systems, load more than 700,000 gallons of cryogenic, or supercold, propellant into the tanks, and fire all four engines at the same time to simulate the stage’s operation during launch, generating 1.6 million pounds of thrust.
The first in a series of increasingly complex missions, Artemis I will test the SLS rocket and Orion spacecraft as an integrated system ahead of crewed flights to the Moon. Under the Artemis program, NASA is working to land the first woman and the next man on the Moon in 2024.

BAY St. Louis, Miss. (NASA PR) — NASA is targeting the final test in the Green Run series, the hot fire, for as early as Jan.17. The hot fire is the culmination of the Green Run test series, an eight-part test campaign that gradually brings the core stage of the Space Launch System (SLS) — the deep space rocket that will power the agency’s next-generation human Moon missions — to life for the first time.
PROMONTORY, Utah (NASA PR) — NASA will broadcast a Space Launch System (SLS) rocket full-scale booster test at 2:40 p.m. EDT Wednesday, Sept. 2, on NASA Television and the agency’s website, followed by a media teleconference.
WASHINGTON (NASA PR) — With 2020 more than half way through, NASA is gearing up for a busy rest of the year and 2021.
Following the recent successful launch of a Mars rover and safely bringing home astronauts from low-Earth orbit aboard a new commercial spacecraft, NASA is looking forward to more exploration firsts now through 2021.
EL SEGUNDO, Calif., July 20, 2020 (Aerojet Rocketdyne PR) — Aerojet Rocketdyne recently completed all of its propulsion hardware for the first crewed flight of NASA’s Space Launch System (SLS) rocket and Orion spacecraft.
The engines and motors, which Aerojet Rocketdyne produces at its major space operations sites across the country, will support NASA’s Artemis II mission. The Artemis II mission is the second flight of SLS and Orion and the first to send an astronaut crew to fly around the Moon.
SACRAMENTO, Calif. (NASA PR) — NASA has awarded a contract to Aerojet Rocketdyne of Sacramento, California, to manufacture 18 additional Space Launch System (SLS) RS-25 rocket engines to support Artemis missions to the Moon.
The follow-on contract to produce 18 engines is valued at $1.79 billion. This includes labor to build and test the engines, produce tooling and support SLS flights powered by the engines. This modifies the initial contract awarded in November 2015 to recertify and produce six new RS-25 engines and brings the total contract value to almost $3.5 billion with a period of performance through Sept. 30, 2029, and a total of 24 engines to support as many as six additional SLS flights.
The latest audit of NASA’s troubled Space Launch System (SLS) finds the program is now even more behind schedule and over budget than previously thought, with the space agency failing to fully account to Congress for almost $6 billion in program costs.
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.
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.
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.
WASHINGTON, DC (NASA PR) — The public is invited to join NASA Administrator Jim Bridenstine at 9:40 a.m. EDT Friday, Oct. 25, for an update on the agency’s Artemis program and the critical role international partnerships have in returning astronauts to the Moon and going on to Mars.
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.
BAY ST. LOUIS, Miss. (NASA PR) — NASA cleared a milestone in preparation for Green Run testing of its Space Launch System (SLS) core stage with an Aug. 23/24 lift and installation of the core stage pathfinder simulator onto the B-2 Test Stand at Stennis Space Center near Bay St. Louis, Miss.
The lift and installation of the core stage pathfinder – a size and weight replica of the SLS core stage – is helping teams at Stennis prepare for the Green Run test series.
Video Caption: NASA is a step closer to returning astronauts to the Moon in the next five years following this successful “hot fire” test of flight engine No. 2062 on the A-1 Test Stand at Stennis Space Center in Mississippi. This April 4, 2019 test caps more than four years of testing for the RS-25 engines that will help power the first four missions of the Space Launch System rockets. It also concludes a 51-month test series that demonstrated RS-25 engines can perform at the higher power level needed to launch the super heavy-lift SLS rocket.
