NASA sets mid-January target for SLS hot fire test

January 6, 2021

NASA is moving forward with a crucial test-firing of the core stage of the first Space Launch System heavy-lift rocket as soon as Jan. 17 after engineers were satisfied with the results of a fueling test last month.

Final preparations began this weekend at NASA’s Stennis Space Center in Mississippi to load super-cold liquid hydrogen and liquid oxygen into the massive core stage of the Space Launch System heavy-lift rocket for the first time as soon as Monday.

Crucial first fueling test on tap for SLS core stage later this month

October 9, 2020

If all goes according to plan, engineers in southern Mississippi later this month will load cryogenic propellants into the core stage of a rocket NASA says will launch astronauts back to the moon, exposing its tankage and internal plumbing to extreme operating conditions hundreds of degrees below zero for the first time. The fueling test — a major milestone in its own right — is a precursor to a high-stakes eight-minute test-firing of the Space Launch System’s four shuttle-era main engines planned as soon as November.

First SLS core stage installed on test stand in Mississippi

Weeks after leaving its factory in New Orleans, the core stage for NASA’s first Space Launch System flight has been raised into a test stand at the Stennis Space Center to begin a series of checkouts culminating in an eight-minute engine-firing later this year.

NASA opts to go ahead with full-duration SLS core stage test-firing

July 27, 2019

After considering canceling a planned full-duration test-firing of the Space Launch System’s core stage in Mississippi ahead of the heavy-lift rocket’s first flight, NASA Administrator Jim Bridenstine announced this week that the agency will press ahead with the test next year, citing safety and reliability benefits for future astronauts riding on the launcher on missions to the moon.
