The LDPE (Long Duration Propulsive ESPA) is based on a Northrop Grumman payload adapter used to help attach the upper stage to the main satellite in addition to hosting a few slots for other smallsats. However, the entire system is powered by the ESPAStar satellite bus, which is in charge of power consumption and distribution as well as ...

This was true both for satellites and space probes intended to be left in space for a long time, as well as any object designed to return to Earth such as human-carrying space capsules or the sample return canisters of space matter collection missions like Stardust (1999–2006) [11] or Hayabusa (2005–2010).
SHERPA is a commercial satellite dispenser developed by Andrews Space, a subsidiary of Spaceflight Industries, [1] and was unveiled in 2012. The maiden flight was on 3 December 2018 on a Falcon 9 Block 5 rocket, and it consisted of two separate unpropelled variants of the dispenser.
The Starship is planned to replace all existing SpaceX launch and space vehicles after the mid-2020s: Falcon 9, Falcon Heavy and the Dragon spacecraft, aimed initially at the Earth-orbit launch market but with capability to support long-duration spaceflight in the cislunar and Mars mission environments. [161] Both stages will be fully reusable.
SuperDraco is a hypergolic propellant rocket engine designed and built by SpaceX.It is part of the SpaceX Draco family of rocket engines. A redundant array of eight SuperDraco engines provides fault-tolerant propulsion for use as a launch escape system for the SpaceX Dragon 2, a passenger-carrying space capsule.
For rockets and space vehicles, propellants usually take up 2/3 or more of their total mass. Large upper-stage rocket engines generally use a cryogenic fuel like liquid hydrogen and liquid oxygen (LOX) as an oxidizer because of the large specific impulse possible, but must carefully consider a problem called "boil off," or the evaporation of the cryogenic propellant.
The EDO pallet mounted in the back of Columbia ' s payload bay. The Extended Duration Orbiter Cryogenic kit (EDO-pallet or CRYO) was a 15-foot-diameter (4.6 m) equipment assembly which attached vertically to the payload bay rear bulkhead of an orbiter, and allowed the orbiter to support a flight of up to 16 days duration.
