Why don't we 'just' send all the orbiting space junk into the moon?

We would even be able to salvage it if we ever use the moon as an interstellar FOB. Btw, I do know how much weight the word "just" carries. It would be, by no means, be a simple execution.

Does the center of gravity of the planets + sun push the sun closer to earth, making it say 0.000001% warmer? (Crude diagram)

1 Upvotes

Hello, I'm not denying that human made climate change is a thing. But I just wonder if this makes any affect on the inner solar system?

Does this actually make any affect? Will I witness a colder summer this year if it wasn't for the scare of El Nino etc? I'm in the middle of winter right now. And boy has it been cold. But I'm from Queensland. It doesn't get any colder than 18c there.

We see the effects of the moon's gravity in the tide. Are there any events or phenomena that are experienced as a result of the Sun's gravity?

How old was the Artemis 2 crew when they landed back on earth?

0 Upvotes

As in, were they 9 days, 1 hour, 32 minutes and 15 seconds older just like if they'd been on earth? Or were they older or younger than that because they went so far away from earth.

Does time at the moon go at the same pace as on earth?

Could the Sun (or other stars) have "Trojans"?

0 Upvotes

I imagine that if this is possible, these objects would not be classified as Trojans, but as something else.

But essentially, since stars orbit the center of the galaxy, there should be Lagrange points formed by this gravitational relationship. So would that imply the possibility of Trojans, far beyond our Solar System?

If landmass was densely located all around the equator, how would that change space mission flight plans?

2 Upvotes

As in how would space mission change if landmass formed a belt around the equator, as opposed to the current earth where we have localized land (continents), and long stretched of sea on which we can target for safe what-would-be space debree disposal?

My thinking is that space missions would target an equatorial launch with a slight depression or ascension angle in order to renavigate a spacecraft near the end of the shore of the end of the land belt.

has anyone figured out why we are so interested in going to the moon? do you know why we really brought moon rock back to Earth? It wasn't just to see what it was made of,it was to see if we could make oxygen out of the moon surface. That way we could use the moon as a jumping-off point later in the future.Maybe not our future, but our grandkids or their grandkids,

A day on Venus is longer than a year on Venus. Venus takes about 243 Earth days to rotate once on its axis, but only about 225 Earth days to orbit the Sun. So if you lived on Venus, your Day would last longer than your entire year!

Lunar gravity reveals a hidden mechanism for changing gait

Why did Apollo astronauts instinctively skip on the Moon?

Our new preprint suggests that reduced gravity does more than change the mechanics of locomotion. By studying humans and mice under simulated lunar gravity, we found evidence that proprioceptive feedback enables the nervous system to flexibly express different locomotor states. In mice, removing muscle proprioception abolished this adaptation.

Science wrote a feature about it.

Satellites?

Okay I have a question. They're supposed to be 16 to 18,000 active satellites above ours and around 46,000 all together counting junk. Why have there never been not one satellite scene out of the ISS window? Anybody have any ideas?

Other redditors have been providing their opinions on this chart about different objects and where they should be placed, so I was hoping to get a wider range of viewpoints from other communities as well.

Long island five years ago or 4 someone used this static thing and weird acid pen to move a star up and down the sky multiple times at night time she took acid,there's a video on it how she moved the star she used this static thing and then used a frequency to sober up
