Why would any be saved? They can't be reused for anything. Any thoughts of saving anything is a child's fantasy. It has no grounding in reality.

Where is this millions of dollars of cost to deorbit coming from that you keep talking about?

Detach the module. Fire thrusters to slow the module down. It falls to earth. That's how deorbiting works.

It would be better to deorbit it while it's still in relatively decent condition, then wait for something to go wrong and potentially have an uncontrolled re-entry and landing on some city.

Is gateway actually being built?

On steam? Can you make basic gifs like this to download and share, with the free version or is premium needed?

Elon seems to be more of a figurehead now. Walks around running his mouth and spending money. While his executives are the ones really running the business.

The success of the Falcon 9 launches is on the personnel actually doing the work, not musk.

How does one make something like this?

Yeah but that tripled time is still faster than anybody else.

Read some of the reviews for working at spacex from former employees. Talking about being worked around the clock.

Elon has stated before if they're going to be successful in their goals then they need to work like there's an asteroid headed towards earth and the only way to stop it is this rocket.

It took NASA over a decade to build SLS which was basically just recycled Apollo. SpaceX is designing an entirely new launch system.

Once again the alien carnival goer misses his chance to score by failing to win his date the giant stuffed teddy bear.

The ball in a sheet cloth is a nice two dimensional model.

But I like this example as a three dimensional model.

Imagine a 3 dimensional grid of bungie cords so you have bungie cords going up and down, left and right, towards you and away, such that the bungie cords are connected at equal segments and the space between the bungie cords forms a cube.

Now grab several bungie cords close to each other and pull them close and tie them together. The bungie segments closest to those segments get warped and stretched out of position while bungie segments further away are relatively unaffected.

In space the spots where the bungies are tied together represent massive objects like stars and planets. And the amount of warping/stretching represents the gravity well around that object.

Much of the time it took for life to form was because the planet was still forming. It was highly volcanically active and was being constantly bombarded with cosmic debris as it was clearing its orbital path. All of that would be a significant hindrance to complex life evolving. As the planet settled and orbital impacts waned then life evolved.

But consider that the moons of Jupiter and Saturn are already formed and have been for some time, and have already cleared their orbital paths. I would imagine the time to evolve life would be much shorter than it was for us. Especially if the time between now in then is full of us sending probes and robots that are contaminated with earths biological materials. All they need is the right conditions.

Sun will become a red giant in about 5 billion years, expanding in size to swallow Mercury, Venus and Earth.

As a red giant, Jupiter and Saturn will fall in the habitable zone so several moons could grow new life.

It'll be a red giant for a billion years.

Then the sun's core will collapse into a white dwarf and the outer shells of the sun will be thrown off creating a planetary nebula that will likely destroy most of the planets.

He's built and testing actual rockets. That's more than anybody else has done.

Well he is currently the only one actually making an effort to go to mars. So logically the topic of going to Mars should include him.

These would be great for locations where you know people aren't going to screw with it. Such as in large businesses or government facilities. They could be used to deliver food or documents or mail or tools.

Consider say you have to send your device to IT for repair. In a huge company campus it could be 40 min round trip just to drop off your laptop. You create a ticket, IT dispatches the bot with your new laptop, which shows up at your office. You take out the new laptop, put in the old laptop and it drives off back to IT.

It was never going to work out in public. Too many people who can screw with it, or other ways it can go wrong.
