SpaceX won‘t reach Mars on their own money. You‘ll have to pay either way.

They're building a craft capable of it, regardless. It is their F9 replacement. We can debate if they will succeed (I hope they do), but they've already stated that they are funding it regardless via commercial launches. ULA and Bigelow pitched a lunar station concept, but said the taxpayers had to pony up 2.3 B$, first. They have no model to build it first, then seek customers, nor does Boeing. If SpaceX can demonstrate BFS closer to home over multiple missions, then yeah, they will likely give NASA a crack at BFS for Mars.

throttle it down to 5%

Unlike in ksp, engines can't throttle arbitrarily low.

Yes! My favorite spaceship!  Radioactive tsunamis are the only downside.

@illectro 

The BFR would have to be delayed 12 years in order for Boeing to win.

Yeah, exactly.

Of course having Boeing do it requires that all of us have a walletectomy every April.

There are far, far worse things I can think of, some in the works, that I could be spending my tax money on, but I'm not allowed to talk about that on these forums.

Some of the money does go to SpaceX, thankfully.

Boeing might be able to beat SpaceX to Mars... Or they might not ever get to Mars. It's irresponsible for Muilenburg to make this claim because he's not in charge of the funding necessary to make it happen.

Best,

He didn't make a "claim" so much as a statement of conviction:

Quote

“I’m convinced that the first person to step foot on Mars will arrive there riding on a Boeing rocket,” he said, according to Bloomberg.

Notice how the tweet doesn't put the claim in quotes.

Yep, it's called the Aldebaran.

Wet mass 50,000 tonnes. Single nuclear-thermal engine.

Someone should clue them in that a “web site” need not cram the entire flarping thing onto a single page.  <_<

Fascinating info, tho. I’m given to wonder if there’s a parallel universe somewhere where that stuff actually exists. 

And everyone lives underground. Way, way underground.

That's his thing. It is tedious trying to find stuff though.

But separating it better would be quote hard I think

They apparently have their mass fraction numbers screwed up. With today's modern turbopumps you would not need a nozzle quite so large.

For a horizontal take-off rocket design to be taken seriously it would need to be a Mach capable design. That space craft does not appear to be able to generate enough lift to take off from water or survive a low altitude MACH speed.

@tater Oh, I didn't think that had been done already! Now let's hope for someone to actually take them to space...

Any funny ideas for licence plates?
