My kid made this meme and asked me to share it on Mastodon. I think you might need to be a Kerbal Space Program nerd to understand it. #Kerbal#KerbalSpaseProgram#SpaceNerd
Here is a photo of the RS-25 "SSME" (Space Shuttle Main Engine) for no reason... because no reason is ever required.
It's bloody magnificent (oh, and WAY greener than anything #SpaceX is using)
#AltText: An RS-25 rocket engine mounted on a test stand (I think), firing downwards. There is a gorgeous, angular blue shock diamond at the bottom of the picture, and an eerie blue glow emanating form the rocket bell. Absolutely breathtaking for this #SpaceNerd.
