I am so happy Elon Musk exists today. The world is a much more interesting place to live in. I was outside the other night on a walk and all the sudden I see a 60 satellite Starlink fleet above me and it honestly brought me to tears. He has made science fiction real and has progressed all of humanity more than anyone else alive today IMO. I can't wait for the Elon hate replies.

> has progressed all of humanity more than anyone else alive today IMO Tim Berners-Lee is alive, for a simple but not maximal example of someone I think could reasonably be said to have advanced humanity more than Musk.

It's not like people had no idea about sharing stuff on the network before him, though. Tim Berners-Lee made the first web browser, but it was evolution of previous ideas and the third small step of a revolution, not a gamechanger by itself.

Anywhere on the globe in less than an hour... plus months of planning and days of preparing the launch vehicle. How fast can one "scramble" a Starship off the ground?

The cost is likely to fall in the 1%-3% range of that of a C-17. The War Department could buy 100-200 of them for the cost of 2 C-17 Globemaster IIIs. I would be interested to see if some form of portable, quickly constructed landing pad could be deployed, much like the mats used as runways during WWII.

Cost per what? Per flight?

DOD is already talking to SpaceX for rapid cargo transport applications. “A military team is working with SpaceX to flesh out the prospect of shipping routes that pass through space, the head of U.S. Transportation Command said Oct. 7.” “That group could demonstrate as early as 2021 whether quickly sending cargo around the globe via space is feasible, Army Gen. Stephen R. Lyons said.” “Think about moving the equivale…

US Military is used to training recruits to use high tech equipment, and had the pockets to buy hardware to sit around "just in case"

Squeezing 100 people into this thing for a multi-month journey continues to give me pause. It has smaller internal volume than the ISS, which has never had more than 9 people, and it was considered uncomfortably crowded when that happened.

Trips to Mars won't be 100 people. More than likely 30 or less. I'm imagining around 15-20 at most. https://youtu.be/Jed1tI_x-KM

Geez, I had no idea C-17s cost $200 million each. That's crazy.

"The cargo version can also be used for rapid point-to-point Earth transport." Why no one is talking about this. This will be game changer if can be done with bigger payload. There are models created earlier that using rocket technology/mechanism, LA-HK can be reached in 2 hours. This can have huge impact on avionics esp with trade.

Ask yourself -- what object would be so massive and heavy and yet needed with such immediacy that a company would be willing to pay millions -- perhaps beyond the cost of the object itself -- to ship in a sub-orbital manner? Large and critical infrastructure components like generators, large piping and ducts, etc. are already transported at a fraction of the cost by the likes of the AN-225 Mirya within a matter of ho…

I mean there's not _no_ market, but I agree it's specialized. I could see this capability making sense for high-value, time-sensitive construction projects, such as oil rigs or wind turbines.

Also, the "global" nature may lend itself to container ship salvage or search and rescue. Esp. if the Starship doesn't need to turn around immediately, I can see a market for that.

All of these seem like they will need special-purpose custom Starships operated by a non SpaceX entity.

I totally agree. I think the plans right now just aren't going to happen, a cycler probably makes the most sense

Yes. Here's Delta IV: https://www.ulalaunch.com/docs/default-source/rockets/delta-...

This looks like what I was expecting to see. The Users Guide from SpaceX looks more like a brochure.

To be fair, Delta IV had been flying for decades

Yup, they got a contract with the military to send weapons anyone on the globe.

> This week, the space exploration company signed a contract with the Pentagon to jointly develop a rocket that can deliver up to 80 tons of cargo and weaponry anywhere in the world in just one hour, Business Insider first reported.

100 people was for the ITS, an earlier concept with a 12 meter diameter. The 9 meter Starship would presumably hold fewer people.
