For the Green Run hot fire test on Jan. 16, NASA set out to acquire test data to support 23 detailed verification objectives. To satisfy the objectives, hot fire test data is used in combination with analysis and testing that has already been completed. These detailed verification objectives are used to certify the design of …
The Space Launch System (SLS) rocket Green Run team has reviewed extensive data and completed preliminary inspections that show the rocket’s hardware is in excellent condition after the Green Run test that ignited all the engines at 5:27 p.m. EST at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. After analyzing initial data, the …
Teams from NASA’s Space Launch System (SLS) Program conducted a hot fire of the Artemis I core stage on Jan. 16 at NASA’s Stennis Space Center. All four RS-25 engines ignited successfully, but the test was stopped early after about a minute. At this point, the test was fully automated. During the firing, the onboard …
The hot fire is underway for the Space Launch System (SLS) rocket core stage at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. Engine ignition began at approximately six tenths of a second before T-0, beginning with Engine 1, then Engines 3, 4, and 2 ignited in sequence a few hundredths of a second apart. The test is expected to last about 8 minutes and will include three different power …
The test conductor polled the team and has approved the decision to proceed with the terminal countdown that includes the final 10 minutes before the hot fire. During the terminal countdown, the team is executing the autonomous launch sequence that simulates the countdown for the Artemis I launch. The test transitions from ground control to on-board software control of the core stage and so the test is fully automated starting at T-30 seconds. Key milestones during the …
The teams are now targeting a hot fire test for NASA’s Space Launch System (SLS) rocket core stage within an hour. The team has completed a successful pressurization demonstration and is evaluating the data to ensure they are ready to proceed. Live coverage is underway on NASA Television and the agency’s website. Teams began the …
Countdown is continuing for the hot fire test of the core stage for NASA’s Space Launch System (SLS) rocket. The test is targeted for as early as 4 p.m. EST and is expected to last about 8 minutes to simulate launch and ascent of the SLS to orbit. NASA Television coverage has begun. Watch live: http://www.nasa.gov/live …
Teams are progressing through the countdown and running approximately an hour ahead of schedule. The test is targeted for as early as 4 p.m. EST. Live coverage will begin earlier at 3:20 p.m. on NASA Television and the agency’s website. Learn more about Green Run, and check back at this blog for updates on the SLS core stage hot fire test.
Engineers have completed tanking for the hot fire test of NASA’s Space Launch System (SLS) rocket core stage at NASA’s Stennis Space Center, and the countdown is proceeding normally. The liquid hydrogen tank holds 537,000 gallons of liquid hydrogen, cooled to minus 423 degrees Fahrenheit. The liquid oxygen tank holds 196,000 gallons of liquid oxygen, cooled to minus 297 degrees Fahrenheit. The cryogenic fuel …
NASA marked another milestone on the path toward the launch of Artemis I on Saturday, as engineers moved the Orion spacecraft out of the Neil Armstrong Operations & Checkout Building on its way to the Multi-Payload Processing Facility (MPPF) at the agency’s Kennedy Space Center in Florida, where the spacecraft will be fueled for its …
