Space Debris Narrowly Misses Airliner 297
An anonymous reader writes "An airliner jet traveling from Chile to New Zealand early today was in for an interesting ride. Flaming space debris — the remains of a Russian satellite — came hurtling back to Earth not far from a commercial jet on its way to Auckland, New Zealand. Here's further justification for the growing concern of the increasing amounts of space garbage orbiting our planet. From the article: 'The pilot of a Lan Chile Airbus A340 ... notified air traffic controllers at Auckland Oceanic Centre after seeing flaming space junk hurtling across the sky just five nautical miles in front of and behind his plane...'"

Absolutely false. That was not space junk. It was atmospheric junk, which is not a problem because it falls, burns, and rapidly becomes either vaporized or on the ground. The problem with space junk is that it just sits there in orbit and never goes away. And the orbit that it is in could cross your orbit with an extremely high closing velocity.
If we could get all of our space junk to become atmospheric junk, the problem would be solved.

Just a couple of technical issues with your justification. First, it was space junk because it didn't start in the atmosphere (unless you count the moment it was launched, in which case I concede). Second, falling debris (whether atmospheric or otherwise)is a problem. Something with sufficient mass that survives the free fall will cause damage. Third, the orbit of space junk is the determining factor as to whether or not it goes away. A piece of debris in a low earth orbit or with a highly eccentric or

I witnessed the same thing about 20 years ago, as I was flying a B-52 westbound over Montana on a night-time training flight. A Russian booster re-entered the atmosphere in front of us, traveling north to south (it had just put a satellite into polar orbit), visibly burning and breaking up. Pilots all over the western US were reporting the sight, many thinking an airliner was burning and breaking up in their immediate vicinity.
The funny thing was that even though the thing was at least 50 to 75 miles above any of us and hundreds of miles away from most of the pilots witnessing it, most were reporting it to be within a few thousand feet vertically, and less than 10 miles away.
The human visual system is just not equipped to judge the size and position of something like this without a terrestrial frame of reference. All pilots are aware of that, but in the heat of the moment, the visual illusion can be extremely powerful.

Actually most of the junk falling out of the sky is the 'good' news, notwithstanding how disturbed the flight crew must have been. (inasmuch as there is good news at all). Most of it is relatively small; that which isn't is usually tracked more precisely. The article notes that they got the timing wrong for the terminal de-orbit of that satellite (and hence the position as well).
The really bad news is the junk that isn't de-orbiting, but staying up there. As the second article notes, even if we stopped all launches today, collisions and resulting fragmentations (creating even more space junk objects) would only be balanced by de-orbiting space junk up until 2055, after which time the number of objects would increase for circa 200 years.
While a $100m satellite being destroyed may just be bad news for taxpayers, or shareholders (and hence pension funds) or TV viewers, or GPS users, it might also be very bad news for people in remote communities who rely on telemedicine. There are a lot of increasingly critical applications that depend on satellites.

The solution is quite simple actually. Since all that junk is orbiting Earth, the position of any one piece of junk at any time is function of the Earth's gravity (and the piece's velocity), that's how orbits work. Since we can't change the junk's velocity (it doesn't have an engine, or we lost contact with it), all we need to do is increase the Earth's gravity for a couple of days and all the junk will de-orbit by itself. How to increase the Earth's gravity is left as an exercise to the reader.
The unfortunate side effect of that solution though is we're in for quite a shock (and one hell of a high tide) in a couple of years time when the moon comes crashing on Mount Fiji...
