The SLS would propel the Orion into an initial orbit, upon which the spacecraft will immediately separate, and then perform a retrofire that will allow the Orion CM to splashdown in the Pacific Ocean off the U.S. West Coast, or make a ground landing at either Edwards Air Force Base in California or White Sands Space Harbor in New Mexico
The Delta Cryogenic Second Stage ( DCSS) is a family of cryogenic rocket stages used on the Delta III and Delta IV rockets, and on the Space Launch System Block 1. The stage consists of a cylindrical liquid hydrogen (LH 2) tank structurally separated from an oblate spheroid liquid oxygen (LOX) tank. The LH 2 tank cylinder carries payload launch ...
On 18 May 1998, the two squadrons merged into the 2nd SLS. The merged squadron was responsible for all launch operations at Vandenberg AFB.
