Look up Bussard ramjets to get an idea of what might be required.

Put in more normal terms, if you marked out a random cubic meter of empty universe, there’s a 2 out of 3 chance you would have no atoms in it.
Seems like it would be a waste of energy...

What gas? It's near non-existence in the vacuum of space

Do you think they’ll make it?

And SpaceX is far from alone is missing targets. ULA is behind on Vulcan, Blue Origin is way behind on New Glenn and BE-4, Boeing is exceedingly late on Starliner service.
It's almost like rockets are hard or something and one hiccup in hardware development puts everything back.

There was confusion once a while back. This time it moved and a lot of it is missing, presumed as used. They were 2 different events

She doesn't have full control. She is the Chief Operating Officer.
Elon still is Chief Technology Officer and CEO, he owns SpaceX. At the end of the day she answers directly to Musk.

A successful static fire needs all pre burners and turbines working. A spin prime is just a test of those components. No real need to wait it out if you are confident with your engine start parameters. They’ve done the spin prime and static fire quite a few times both on vehicle and at mcgregor. Now it’s time to light the candle.

She is simply the head of the starship program. She tends to be moved into position during the transition from R&D to application. It’s not her first rodeo.

Right, also you could see them moving. Not all of them, like one while the other were dim. Then as you said they would reappear forming a triangle

I think you're saying: each of the lights would disappear and reappear in a different position, and those positions formed a triangle.
Is that right?

They were going bright and fading. Then when they appeared again they’d be in a triangle. Then one of them would go really bright then all dimmed again or fade and when they appear they were in another triangle. And so on. Sorry I can’t explain it better

The chances of gathering enough meaningful particles would be not worth the effort. However, we now know that water is notably common on other celestial bodies. So we can gather resources from there and convert the water into hydrogen and oxygen molecules.
