The RS-25 just did a 600 second test. I doubt Raptor could match it. I think RS-25 could probably burn even longer. Perhaps converted to methalox with Raptors used for landing?

A lunar elevator is perhaps the most doable. This object is the nearest asteroid that sticks around. Now I think asteroid mining might best be done by coaxing an asteroid’s mass into cables and drawing them out for ease of transport. Now I think two elevators might be better. Imagine two...

And his family has to use a Go Fund Me? “Safe Is Not An Option” Mr. Simberg? The man in a coma is Francisco Cabada-say his name: View: https://m.youtube.com/watch?v=rga4gjPhECo&feature=emb_logo

We also saw “rays” of ejecta in action.

A docking adapter was left behind: https://en.m.wikipedia.org/wiki/Hubble_Space_Telescope#/media/File%3ASoft_Capture_Mechanism_installed_on_Hubble_(illustration).jpg One Crew Dragon could shove it…but for a repair, a cargo dragon minus its capsule with a cage-deal in its place with equipment...

I don’t think most people would care if Shostak had squiggles on a graph…I’m sorry to say.

Now, I once heard it said the universe’s energy budget is close to zero somehow. A black hole gives infinite compression…and perhaps is enough to bud off another universe. I guess that means the multiverse is diesel…

You mean warp ship? Perhaps The closest thing to the Enterprise was this Shuttle-C type concept here—see Figure https://www.aiaa.org/docs/default-source/uploadedfiles/about-aiaa/history-and-heritage/shuttlevariationsfinalaiaa.pdf?sfvrsn=b8875e90_0 If people will stop trying to kill it, SLS...

Well, if we ever get a real warp ship…it will have to be ring shaped. Matt Jeffries actually drew one very early on. He was on to something

I want to see Sea Dragon fly

I think that is India’s
