And the people inside it are so tiny!

 

I'll admit, until Eric Berger retweeted it with the comment "With people, for scale." my brain could not process that those were people inside of it o_0

 

The plot thickens:

Wow, gives you a sense of the scale and interior dimensions.

 

It took me a minute as well. I kept trying to reconcile the people blobs with parts of a Raptor engine.

 

Skylab Habitable volume: 361 cubic meters

Starship Pressurized volume: approximately 825 m3

The picture doesn’t do it justice. Skylab was built off the third stage of the Saturn V (as noted between the lines.



Starship, if successful, is an absolute game changer.

What a shitshow

 

A single starship is just under the interior volume of the ENTIRE iss. This is it though. Elon has said that there won't likely be a larger rocket, going to stick to 150 tons like jets have. So if anything larger is built it will likely be built and stay in space.

 

Payload + launch vehicle vs fuel has a pretty hard cap I guess unless there’s a drastic change in efficiency.

He said building the vehicle was easy, it was the infrastructure to support that vehicle that becomes difficult iirc. The crane to lift a larger rocket for example would not only have to get taller, it would get much wider as well.

Efficiency wise there is a TON of potential. Right now Starship is predicted to be about 75% more expensive than an airliner, but with more than 4,000 tons of fuel single digits in efficiency increases could allow it to quickly catch up, and as is shown in a previous post where they're already gaining 45 tons of thrust per engine, they're working on it before they've even proven the rocket will fly.

 

Boeing has some competition!!! This module has been nothing but problems from the beginning.

 

The Russians have a bit of history with these things...

It's a good read, almost in the non-fiction space horror genre.
