Do our ocean tides not completely depend on the moons gravity?

If they aren't looking at the sun, or anything lit by the sun, they can see stars just fine. Your surroundings just need to be dark enough to let your eyes become dark adjusted.

You don't actually need Earth blocking the sun for you, you just need to look away from the sun and anything lit by the sun.

If you have access to a camera with manual exposure settings, here's an experiment: Setup the exposure for a properly exposed, sun lit daytime photo.
Without touching the settings, take the camera outside at night, point it at the sky, and snap a photo. What do you think you'll capture?
The answer is: nothing. The stars are far too dim, compared to sunlight, to show up in the exposure at all. Most space photography is done in sunlight, of things that are sun lit. The cameras are set to properly exposed these sun lit things, and the lack of an atmosphere doesn't change the fact that the stars are just too dim to show up in the same exposure.

Elon isn't being completely honest or more likely is miscategorizing costs somewhere.
​
The NASA contract to develop F9 WAS 400M. That is a fact. The actual contract is more reputable than the words of a man known to exaggerate to absurd degree.

I walked too many football fields, and now I have acre feet.

Categorically false. Read my source.

AFSC has been at been at Peterson since 1982. If you read their mission it aligns with USSC. It only makes sense but having served 24 years I know that's not necessarily a consideration.

Acre-feet is an agricultural term so that's probably why you haven't heard of it. Feet of water is generally used to describe how much water a plant needs, acre-feet are how much water a crop needs (almonds need 4 acre-feet of water annually in California.)

400M from NASA alone, not counting their other sources of funding.

If you are an astronaut, can you see stars other than the sun?

This is the first time I’ve heard of acre-feet. Why can’t we just use OSI measurements like football fields?!

It’s been cloudy though…I wish I had a telescope that could see through clouds

And we have complete cloud cover as is the case during any astronomical event.

Now, let's take a moment to appreciate the wide dynamic range of the humen eye. Sure, if you look at the sun you will damage your eyes but it's still possible to see the contours of the sun, it's not a big white blur in that part of the sky.
And with that same "tool", we are able to clearly detect stars at night.
