Wow. Imaginative question, and the stark answer is… “no.” Although there is stuff in space, it’s so sparse that it’s a vacuum. There’s no “pressure differentials” in the vacuum of space. We can’t actually “see” stuff moving apart in the universe, but we perceive it by the shifting of light, indicating to us that stuff... Continue Reading →
You think that’s fast? Think again. At it’s orbital distance, as you know by watching the moon itself, it takes about 28 days to orbit the earth. Very roughly speaking, the moon rises about an hour later each day. That’s why you can still see it. But you don’t believe this answer because you think... Continue Reading →
A paint chip traveling a relative speed of 34,000 mph chipped the glass on the ISS. Sometimes known debris causes them to move the station and for the astronauts to take shelter, but small stuff like paint chips are unpredictable. These are the main problems.
As Bobby Sherman has already pointed out, we have sent spacecraft to the surface of Venus and Mars. We’ve also sent people to our moon and a lander to Titan orbiting Saturn. We’ve retrieved photos from all these places. Here they are. First, our sister planet Venus (sister because it’s almost the same size as... Continue Reading →
Yes. That’s why I asked that question. Well, of course not! We are all different - unique beings. Minute differences in genetic makeup from birth, ancestry, gender, upbringing, chemical makeup of the brain, experiences and consciousness make us all have different minds and psyche.
Nope. Not-a-one. Of course, you didn’t say what “close to Earth” means, but even without that, we don’t know of any habitable exoplanets anywhere. We only know of exoplanets that might resemble the approximate size of our planet and within what we envision as the “Goldilocks” zone around a star. Of those, the nearest system seems to be...

In order for an orbit to be sustained it has to keep going around the planet, but if you put the orbit so low it slows down due to atmospheric drag, whether here on Earth or on Jupiter, the orbit will rapidly decay and the orbiting object will fall. If you want to put something... Continue Reading →
Great question. NASA does plan to go to an asteroid, grab a big bolder, and put it in orbit around the moon. After that they want to send astronauts there to explore it and bring back samples to Earth. As far as actually doing commercial mining on one of these things is pretty far off... Continue Reading →
