I used to do this all the time as a kid. The moon, Mars, the moons of Saturn, etc. I would like on the grass or if the full moon light was coming through my bedroom window, I would bask in it, imagining I was walking on the moon.
Saturn was the best, I don’t know which moon I was on, but looking up you could see the rings.
It’s good to see scientists catching up. I think they’ll find a lot of nice things in imagining going to Mars, like you don’t need space suits and it goes a lot faster.
Going to Mars, I wonder why NASA doesn’t make it a one-way trip? The crew could be selected from astronauts with looming- or dooming- cancer issues. In my eyes, they’d all be heroes, and should be granted a “stasis pod” on Mars.
