This is going to require a lot of plumbing

[kunok]

Diferents engines for sea level and for vacuum?

[RedKraken]

ITS 1950t prop + 150t dry

ITS tanker 2500t + 90t dry

6 vac + 3 atmos raptor config

450t to mars

115 day transit on average down to 80 maybe less

No, just different nozzle configuration if i understood it right.

[RedKraken]

Yeah, that, but why? Its a lot of extra weight

[RedKraken]

$100k  + luggage.... i travel light

Different atmospheric pressures require different nozzle shapes for optimal Isp. Check the KSP engines, they all have different vacuum and sea level Isps, and some are better for vacuum, others for sea level

I guess their analysis suggest that the performance gains offset the extra mass.

By the way, keep the comments coming. I can't open videos on my work computer and my data plan is over for the month, you're my eyes and ears

Steal underpants... yeah!!!

[RedKraken]

too heavy ... use carbon fibre

[legoclone09]

Profit.

 

Oh my god, it's insane. SEVENTEEN METERS.

$140000/ton.

Insanity.

Musk is a god.

Say what you want about SpaceX, but their evolution from an upstart company to one of major players in space industry in little more than a decade is awe inspiring.

[tater]

He's doing history of spacex right now.

[StarStreak2109]

Well he definitely has ambition!

[Steel]

Holy ambition Batman!

4 years for an experimental flight!

Nobody denies that, but we can also don't trust the rest of the plans of elon.

Seriously this time I didn't feel convincing at all.

[Scotius]

Well, apparently Elon intends to push Fed-Ex out of business. And take their place with packages sent to every place on Earth with rockets

[RedKraken]

45min SSTO postal deliver to anywhere on earth ..... just need ear protection and a safety bunker

im thinking very small rockets would be better for this <100t

"Guys i need you to build a really small BFR"

"....u mean a SFR?"

"yes"

Woah!

[kunok]

He doesn't really know how the rocket will get to the launchpad
