SpaceX Discussion Thread


Recommended Posts

Still weirded out by Bridestine... i haven’t seen anything yet that makes me feel like his official statement was anything other than a tasteless attempt to steer the limelight back to NASA’s programs, which when compared to SpaceX seem embarrassingly poor bang for buck and excruciatingly slow

I haven't been following too closely, but has the chutes ever been a point of issue for D2 (guess now D3)? According to these reports, it sounds like they found some serious flaw.

They have worked (recovered every Dragon, including the Crew Dragon test to ISS), but they have some issues they are not pleased with. Think it appeared with the change from 3 to 4 chutes, some line tangling.

Way overkill, they are also designed as semi submersible so they can drop the cargo deck below the water to pick up stuff. 
You want large but simple oldish ship, tanker, bulk or container. You could add wings on it if needed, this let you get away with an much smaller ship, 100 ton is nothing for ship loads after all. 
Use an old tank as the rumba robot for falcon 9 drone ships. Guess some engineering tank designs would work. Down the line you might want to pick up multiple first stages before returning.

They're ideal, for their low deck in relation to their center of mass, for a big honkin booster.

Again 100 ton is not heavy in shipping, its lightweight. As an bulk cargo is oversize but still two M1 tanks are heavier, 4 trucks might be heavier.

Yeah, but lots of deck means lots of structure underneath it

What a waste of time that was. Just more of Bridestine using SpaceX’s popularity as a soapbox for his tiring rhetoric imo. 

I thought that was a pretty good talk. Shows that the two agencies are on good terms, we got some new info (parachutes, NASA further acknowledging Starship, some good Q&A questions, some new schedule targets) etc.

When Bridestine was selected to head NASA for the Trump administration, he was a climate change denier, continuing the trend of "worst possible picks" in the administration.

Fortunately NASA was able to convince him, in about 2 days.

So we've discussed a lot about how orbital refuelling allows starship to take some pretty incredible payloads beyond LEO. 150t to TLI is over three times Saturn's previous record.

I've just seen it suggested that orbital transhipment of cargo could allow a single starship to take 750t through TLI on a full propellant load.

That's insane! :o

The problem is that you are still limited in how much you can lift and the size of the cargo bay giving this an limited utility. That is unless you make an in space only version of it with no nose for lifting space stations from LEO. 

But its no problem if main payload is an 3rd stage you fill up in orbit together with the starship. Burn, release 3rd stage an its payload who continues the burn. You probably need an 4th stage here to.

If the payload is a methalox third stage performing a one way delivery to the lunar surface, that's in the region of 380t landed.
