NASA and Boeing to try again after canceled SLS hot-fire test


The agency said Friday night that NASA made another attempt to test its massive space launch system rocket the following month.

The rocket’s 212-foot-long core stage will try to fire four of its engines for eight minutes at NASA’s Stennis Space Center in Mississippi. The effort is the last milestone “Green Run” test before Bee’s rocket is flown to Florida for its launch toward the moon.

All four of the rocket’s Aerojet Rocketdyne RS-25 engines ignited for the first time earlier this month. But what was the intention of the eight-minute exam, it only lasted a little over a minute – a much shorter runtime than the engineers to advance to Florida. The SLS core has been in development for a decade, and consistently late and over budget.

“Conducting a second warm-fire test will allow the team to repeat operations from the first hot-fire test and obtain data on how the core stage and engine perform over the long term that simulate more activities during the rocket’s launch and climb. Is, ”NASA said. In a blog post late Friday night.

NASA is targeting November for the first launch of SLS, but the agency’s inspector general and the country’s largest monitoring agency, the Government Accountability Office, say it is unlikely. Instead, he indicated that the projection was likely to slip in 2022. NASA remains publicly optimistic.

“It is still possible to launch Artemis I with this test in February this year,” NASA spokesman Catherine Noble told The ledge.
