Test is step before first unmanned launch later this year, in push to land humans on the moon again by 2024
Nasa’s Boeing-built deep space exploration rocket, Space Launch System (SLS), is set to fire its behemoth core stage for the first time on Saturday, a crucial test for a years-delayed US government project facing mounting pressure from emerging private sector technology.
The SLS hot fire test, expected to begin at 5pm CST Saturday at Nasa’s Stennis Space Center in Mississippi, will cap a nearly year-long “Green Run” test campaign to validate the rocket’s design.
