It's possible. Soyuz and other crafts arent shielded nearly as well as the rest of the ISS, which is heavily shielded. And they're constantly being bombarded with objects.
To put into perspective, the LDEF was put into orbit in 1984 and recovered in 1990. They found over 5000 large impacts and 30,000 small ones.

Nuclear rockets won't "ignite" until they're in a nuclear safe orbit, and it will be on a escape trajectory away from Earth. And a large rocket as you propose likely won't be able to have any prolonged operation in LEO, it would be above where the majority of debris is.
All of this ignores the simple fact that this isn't a video game, you don't just drive around picking up trash. You can use it to send trash away once you collect it, but it's not even remotely a good proposal on how to collect it.

Uh, theyre not saying that. Their eventual goal is 95%. That means they only have to shed about a ton off, but none of that will really lower the part count much-which is there first goal(which suceeded). They made a rocket with 100x fewer parts than others and you're calling it a failure. Lol

Reply to comment by RedshiftWarp in So from what I understand Sagittarius a is in the Center of Milky Way. If any planets orbit this black hole would there be time dilation? by EarthInteresting9781
It's not really.Were orbiting the center of mass of the whole galaxy, Sagittarius A* just happens to be near there, but if it was to disappear not much would happen out this far.
Sagittarius A* is about 4 million solar masses, but there's possibly about 65 billion solar masses in other stars, then about a trillion solar masses or more in dark matter. We orbit around the center of mass of all of it, and so does the black hole which only makes up about 0.0004% of the total mass(though it could be located right at the barycenter?idk).

It's impossible to 100% 3D print one. Alot of that weight is in things like electrical cables, computer components, rubbers, and fasteners and fittings.
That 85-90% is all the main component mass. That's impressive.

How is the object going in a desired location. The chances of it's trajectory being exactly where we want it to be is unlikely. But even so, we manage to hitch a ride. Oumuamua at it's perihelion was doing 87km/s, but climbing away from the Sun slows it down. From what I see it will average about 26km/s. At that speed it will take 15,000> years to leave the solar system, and about 50,000 years to reach the nearest star.
As crazy as it sounds, it's not fast enough.

They call it a dry/wet moon, smiling moon, or Cheshire Cat Moon, and many other names in different cultures https://en.wikipedia.org/wiki/Wet_moon
Simple answer, due to the tilt of the Planet changing the angle of the Sun as we orbit around it and the angle of the orbit of the Moon around Earth, the angle of the "line" of light changes. Depending on where you are, that line of light goes from almost vertical to more horizontal.

Reply to comment by deluchas15 in NASA's Curiosity rover spots "sun rays" on Mars for the first time by CBSnews
They don't affect Mars, they are an effect of Mars' atmosphere at sunset.
On Earth we have a lot of images of sun rays, light coming through clouds being visible in the air. But Mars only has a few cameras on it, so the chances of seeing sun rays is much less- it finally happened.
But it's not just about looks, it helps researchers better understand things such as Mars' atmospher or weather.

It's one image, with the Supernova's galaxy appearing in it 3 times, at 3 different moments in time. The duration was estimated using scans from Hubble last year. Believing it to be a type Ia supernova (which all have the same luminosity) allowed them to plug the numbers and figure out the precise "prescription" of the lens that galaxy in the foreground is creating. JWST confirmed it's a type Ia supernova, which means their numbers are accurate.
Lensing is pretty well understood and they have amazing software to help them out.

Who cares how Musk words it. It's literally the 1 lunar lander lawsuit, and 1 letter filed to the FCC(along side many others from other telecoms).
Musk has more lawsuits, and more public letters to the FCC against other companies than anyone.

Lapulapu's forces being 1500+ is a extremely heavy overexaggeration, the censuses from that century show it would only be a small fraction of that number.
And he wasnt stupid for thinking he could win; a small armored force defeating a large force of indigenous tribes isn't that rare, if anything this should have been an easy victory. Lapulapu was just a better tactician, or more so Magellan was a poor tactician.

L4/5 isn't stable for larger object. If Theia collected enough mass it would nudge itself out without the help of other bodies of mass. Being about 10% Earth's mass in the Sun-Earth L4/5 points I believe.

That's just a theoryfrom Hancock and his ilk , even your own article says as much.
However, those claims of Gobekli Tepe's connection to the night sky have been largely rejected by the main team actual excavating the temple.

Shooting a gun with a typical hold would send you into a constant multi axis spin as well. Seeing as the forces are being applied off your center of mass. It's not like you would just fly backwards.

Effects of radiation. While exposure rates are higher on the ISS than the ground, the rate in space, the Moon, or Mars is much higher. It's also much different than we can test on Earth.
If we plan know sending humans farther than LEO than we Need to study this. But if their argument is we shouldn't send people, then there's really no answer as to why the program is a necessity.imo

It's not Chinese satellites that make the Doom reports, It's the first stage of their Long March rockets. They launch them up there without any means of a controlled de-orbit.
They're almost 50,000lbs, this old US satellite is only 5,400 lbs. Big difference.

It's a lot of added weight. The solar array is a thin film that gets fanned out. To add a whiper brush would add a lot of weight, and would need different design array that is rigid enough to be brushed.

They don't often notice the strikes inside, the station takes MMOD hits daily.
Just looking at some data- SpaceX dragon 1, missions CRS-1 - CRS-17 spent a total of 410 days exposed at ISS. In those days it collected a total of 246 MMOD impacts. That's an impact on average every 40hrs.Or even worse, the MPLMs in 10 missions with almost 70 exposed days collected 398 impacts. Some of which completely penetrated the hull.
