What happened to the 2nd stage of the Delta IV launcher
What happened to the 2nd stage of the Delta IV launcher ? It managed to circularise its orbit, but used more fuel. What normally happens to 2nd stages of GPS launcher rockets (deorbit themselves ?) ? What did this one do after separation from the GPS satellite ? - Rod57 (talk) 09:52, 21 July 2020 (UTC)
