The #Rocketdyne RS-25 or #SSME was upgraded to the RS-25D, capable of 104% of the original #thrust.
The #RS25 is being modified into the RS-25E, and expendable version for the Space Launch System.
Rocketdyne’s experience with the SSME led them to create the expendable RS-68 for the Delta IV launch vehicle, though it was not suited for SLS due to the large solid rocket boosters on the #SLS #rocket.

After #NASA retired the #Space #Shuttle in 2011, they planned to send the #Orbiters to museums. To get them ready, NASA removed the #SSME #rocket #engines and replaced them with replicas and decontaminated the parts of the Orbiter that held toxic fuel for in-space maneuvering, then be put on the Shuttle Carrier Aircraft.

In this #photograph, #Atlantis (closer on the left) and #Endeavour (on the right) have been brought nose-to-nose for #photographers and #journalists to tell the story of the Shuttle’s #retirement.

On this flight Endeavour delivered the Alpha Magnetic Spectrometer-02 to the ISS.
This was Endeavour’s final flight, and in this image it’s being towed to an #Orbiter Processing Facility to be serviced and readied for museum display. The focus is on the Shuttle’s aft “#boattail” section with the 3 #SSME’s and 2 #AJ10-190 orbital manuring #Engines
