and thats not taking into account deliberate shooting down of sattelites with missiles, say if one nation was loosing a war badly and blamed the other side supplying weapons to their enemy....

Simply because we don't know how long perseverance would still be working to hand over the samples.

And it's not dropping them along a path. This is called a depot, it's one place where it is placing a bunch.

thats only if anti-satellite missiles arnt used, thats my biggest worry, not an accidental collision, but a series deliberate shoot downs of satellites from one side or another...

Say Some nation was badly loosing a war and wanted to threaten the west....

The second time around, his initials stand for "Jesus Fucking Khrist"

You would need millions of these to have an impact. Which would lead to added debris if these things collide with each other...

We can deorbit the big objects, that removes the largest source of new debris.

The Solwind ASAT Test was the F-15 launched ASAT to low LEO.

It produced debris that orbited for nearly two decades.

To add on to the other comment, these deposits are made in very carefully selected locations that would be used as a backup in case the main samples are unable to successfully be returned to earth. They'll get a little dusty, but with the way it works on Mars they will be able to sit perfectly sealed for many years before they'll be covered with enough dust to be hard to locate

Space Medal of Honor is the coolest name for an accolade of all time

You're right. An f-15 with our first ASM. Way back in the mid 80s.

Makes me wonder what kind of sophisticated ASM's we might have now. Or perhaps other anti satellite munitions.

Personally I'm hoping for big ass lasers, for obvious reasons.

Yep you're right. My B

Also, BYU? Hi neighbor.

I was at the Space Resiliency Forum in December, and the DoD is certainly taking it seriously…

Also some pretty brilliant folks around space seem to be taking it seriously: McKnight et al.

ESA

Even NASA is working on active debris remediation due to the issues caused by orbital debris

NASA ADRV

Sure, we could likely still launch to MEO and beyond just fine, but the ISS orbits at 400km. Orbital reef is set to orbit at 500km. We would completely lose sustained human presence in LEO for up to hundreds of years.

Decay by altitude

But I am sure the wiki explained all that to you.

F-15 actually

It was in 1986 weapons system test

You might be thinking of the F-15 that fired the missile. The missile actually had target-seeking capability so really the F-15 was mostly just an expensive missile launcher.

Oh my God yeah, someone call the pentagon, we've gotta be able to sell it to them with this description.

Getting from orbit to the moon is many magnitudes more difficult than getting from orbit back to earth.

If we were able to create such a vessel, bringing it back to earth would be so much more efficient.

The highest orbits are about 23,000 miles above our planet. With the moon being 238,900 miles away on average. And unfortunately we are nowhere near being able to design such a craft. Things in orbit are not just sitting at a consistent speed that we could vacuum up by moving slightly faster.

No no, you have it all wrong, the planets are all fixed to transparent spheres rotating around Earth, even the old greeks knew that!

Eh, there are other electric engine options that are better than ion engines, such as plasma engines or mass drivers. And if power isn't a limiting factor the ultimate in propellent efficiency is a photon rocket, aka a light bulb. No need to carry propellent, though you need 300 megawatts of photons to get a pathetic newton of thrust, so whatever reactor is powering it will need a shit ton of fuel. Though if you're using a laser array to push a mirrored sail that power plant can remain on the ground.

Again out of my league but collection of junk would take place in orbit/outside orbit then moved to a transport vessel that could get scooped before the trip out to the moon?
