Description

Finally, the last SLS design I have to upload. This is the Space Launch System Block 2 with he Earth Departure Stage rather than the Exploration Upper stage that is actually being developed, I call it the 2B. Thanks to the EDS and advanced SRBs it can put very heavy payloads into deep space and over 130 tons to LEO. The EDS is essentially any upper stage powered by the notorious J-2X engine. NASA has been working on the J-2X for decades but the engine is insanely complicated and a lot harder to develop than anticipated. It was one of the main reasons the Ares V and I would have taken so long to fly. Eventually this is what led NASA to pursuing the much simpler EUS which relied on the proven and still active RL-10, which was originally designed for the Lunex Program. The interesting thing is that the J-2X and EDS were never cancelled but rather put on hold. It is most likely the project could start up again in the late 2020s or mid 2030s when heavy Mars payloads are required.

I also included a lunar lander so you can use the EDS as it was intended. It’s original purpose was to ferry landers to lunar orbit. You can launch crew separately from my SLS Block 0 or any other crewed vehicle. The design isn’t based on any real vehicle but is supposed to be a modernized FLO lunar lander.

Just like my Super Detailed Saturn V, this vehicle is as accurate as possible but detailed is used very loosely since a lot of information is missing since it wasn’t perused by NASA.

Controls:

1- toggle lander fuel cells
2- toggle descent stage
3- activate ascent stage

Development time was about 1 ½ hours.

A stock rocket called Detailed SLS Block 2B + lunar lander. Built with 167 of the finest parts, its root part is fairingSize3.

Built in the VAB in KSP version 1.8.1.
