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 …
Payloads Asian Herbs in Space: The crew preserved samples in a Minus Eighty-Degree Laboratory Freezer for ISS (MELFI) and closed out the Asian Herb 30-day plant growth experiment. Microgravity affects the growth of plants and understanding the nature of these changes is important for future missions that will rely on plants for food. Asian Herbs …
Countdown is continuing for the hot fire test of the core stage for NASA’s Space Launch System (SLS) rocket. The test is expected to start soon and 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 powered up the core stage’s avionics …
NASA Television coverage of the Space Launch System “Green Run” hot-fire engine test will begin at 3:45 p.m. EDT.
Engineers have completed tanking for the hot fire test of NASA’s Space Launch System (SLS) rocket core stage at the agency’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. After …
A day before Expedition 64 relocates the Soyuz MS-17 to another port on the International Space Station, the seven-person crew continued studies on the effects of microgravity on humans, plants, and materials, along with a couple outreach events. NASA astronaut Victor Glover took part in two media events, each accompanied by a different crewmate. First up, …
The test team conducted a pre-test briefing in the Test Control Center at the B test complex at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, and gave a “go” to proceed with testing and to fill the propellant tanks. Over the next several hours, the teams will monitor the systems and load more than 700,000 gallons of cryogenic, or supercooled, liquid oxygen and …
Payloads Antimicrobial Coatings (AC) Touch: Per standard procedure, the crew touched both the coated and uncoated coupons for this long-term investigation. Boeing Environment Responding Antimicrobial Coatings tests an antimicrobial coating on several different materials that represent high-touch surfaces. Some microbes change characteristics in microgravity, which could create new risks to crew health and spacecraft systems …
During NASA’s Green Run hot fire test, the team will be especially interested in several key operations when testing the Space Launch System (SLS) rocket core stage under conditions it may experience during a variety of deep space missions. Green Run, an end-to-end system test of the core stage with Artemis I flight hardware, will …
