Because if you launch something from Earth, you inherit the Earth's orbital speed around the Sun. At that point, whatever you launched will just continue to orbit the Sun. It takes less energy to accelerate to a solar system exit trajectory than it does to scrub off all of the excess velocity and end up on a trajectory that intersects the Sun.

Even the Stream version doesn't require Steam. You can just run the executable. A few folks over on Reddit claim they've given the game to their friends just by copying the files from an external drive.

Most of the Falcon 9 launches are for Starlink and are paid for by SpaceX themselves. How is that "the government subsidizing them"? If you want to argue that they're using money they got from NASA to fund those launches, is your plumber feeding their family from you subsidizing their life?

There's two main benefits: faster reuse and more payload to orbit.

A Falcon 9 landing on a drone ship needs to be transported back to shore. That's multiple days before the engineers even get their hands on it to prepare for the next flight. The design goal of Starship is to launch a Ship into orbit, return to the tower, be restacked, refuelled and launched again in the same day. Will they actually get it to the point where that's possible? Remains to be seen. Until now, they had no way to see what real stresses a Starship booster goes through in a flight. They're gonna rip this one apart down to the spacers in its bolts to examine it. With the flight and physical inspection data, they'll make what improvements they can to the already built boosters and design future boosters to be more resilient. SpaceX has, by now, a well proven track record of doing what others think is insane to even attempt. If anyone can launch the same rocket twice in a day, there's no one better to give it a try.

The increased payload comes from not having the mass of the landing legs. The Falcon's landing legs weigh several tons. Starship, being 3x the diameter and 10x the mass, would need titanic landing legs. That's a lot of tonnage you won't be taking to orbit. Catching on the tower means that all but a fraction of the landing hardware's mass isn't on the rocket itself. As an additional benefit, the landing hardware needs to be built only once. Every Falcon has its own landing legs, but every Starship they ever build could land on the one tower they have now. That won't be the case, they're planning to build multiple towers, but the sentiment remains the same.

Right now, the Earth is losing mass at about 55 000 tons per year. Yes, losing. About 100 000 tons of hydrogen and helium escapes the upper atmosphere, partially offset by roughly 45 000 tons of dust and meteorites getting scooped up along our orbit.

Considering this has been happening for millions of years, I think we're quite safe from affecting the Earth's mass and orbit within the span of even centuries.

But it's much more likely that the majority of material mined and processed in space will not be coming down to Earth. It's much better put to use in orbital construction, or shallower gravity wells like the Moon and Mars.

You're entirely right that getting to the rocks, and getting the mined stuff to where it's actually useful, are gonna be a problem. Maybe we'll finally get some nuclear thermal engines, cause the shite ISP of chemical rockets is really insufficient for these trips and ain't no one wanna wait on the gravity assists.

Fingers crossed this woman doesn't end up with a Zydrate addiction. It comes in a little glass vial, you know.

NASA has the measurements of all their astronauts and Dragon flight suits for Butch and Suni are already made.

Crew Dragon has been solely responsible for the US side of ISS rotations for four years, without incident. 8 successful missions, not counting the privately funded trips. Cargo Dragon has been doing resupply missions since 2012.

Yep. And if they fail to deliver on the lofty expectations they've created here, the backlash is going to be epic. I don't want to root for their downfall, but.... Imma stock up on popcorn.

A lot of that time, if not the vast majority, is likely performance testing. That's trivial to automate and can be run across 100+ systems simultaneously.
