Related Facts:-

  • On 17 January 2021; NASA conducted a hot fire test of the core stage for the agency’s Space Launch System (SLS) rocket.
  • It should be known that SLS will be used to launch the Artemis I mission to the Moon this year.
  • The hot fire is the final test of the Green Run series of Space (SLS) rocket of NASA.
  • The test plan called for the rocket’s four RS-25 engines to fire for a little more than eight minutes, it is the same amount of time it will take to send the rocket to space following launch.
  • The team successfully completed the countdown on the B-2 test stand at NASA’s John C Stennis Space Center in Mississippi; the rocket’s all four RS-25 engines simultaneously ignited.
  • All gone well in the initial moments, but the engines shut down by the computer a little more than one minute into the hot fire.
  • Teams are assessing the data to determine what caused the early shutdown, and will determine a path forward.
  • In this test, the 212-foot core stage generated 1.6 million pounds of thrust,
  • The hot fire test included loading 733,000 pounds of liquid oxygen and liquid hydrogen – mirroring the launch countdown procedure – and igniting the engines.
  • According to NASA’s Administrator Jim Bridenstine this test was an important step forward to ensure that the core stage of the SLS rocket is ready for the Artemis I mission, and to carry crew on future missions.
  • Although the engines did not fire for the full duration, the team successfully worked through the countdown, ignited the engines, and gained valuable data to inform our path forward.
  • Mr. Bridenstine stated that if the issue turns out to be minimal, its possible another hot fire isn’t needed.
