What Was the First Piece of Man-Made Space Junk? 34
Splynn asks: "I was wondering about what the very first man made object to leave Earth's atmosphere was. We all know that Sputnik was the first man made satellite, but there must have been something that actually made it out there befor Sputnik." For those who are curious, Sputnik was launched on October 4, 1957. Sputnik may have been the first satellite to orbit the earth, but was it really the first successful launch into space?

If you set some altitude then you can figure out easily which rocket was first.
One of the V2 rockets fired by the United States in 1949 reached an altitude of about 250 miles. This was a modified configuration from the way it was originally built by the Germans.

I'd imagine that is asking what the first thing we put into orbit was. If no screws came off experimental V2's, then I'd imagine that the first real "space junk" was put up with the atomic bomb detonation at Trinity.
There is actually an interesting story in regards to this. When the SR-71 was first built, they were surprised to find little black impact crators on the wind-shield--apparently received while the bird was flying at maximum altitude. Of course, that is far too high for debris. Later, after analysis, they came to the conclusion that the SR-71 had collided with insects thrown up by nuclear detonations. You can think of it as our first problem with space (high-altitude anyway) junk.
The Sputnik booster..... or a camera. (Score:1)
If we define "space junk" as "equipment brought into space for some other purpose but which unintentionally ended up being left, unusable, in orbit" then the honor would go to the camera that one of the Gemini astronauts (Ed White?) accidentally let go of during his spacewalk.
Note: I read all this when I was in elementary school, so I may not have the details right.

Here's a link [go.com] about a test launch a few months before Sputnik. The US was testing Vanguards at the same time, though, and there were other ballistic missiles on both sides.
Come on, someone must know the answer!
Other space junk (Score:3, Interesting)
Less known is that just after Sputnik was launched a bunch of the engineers grabbed whatever they could lay their hands on and attempted to orbit their own satellite dubbed NOTSnik [navy.mil]. They made six launches and while they were unable to prove a successful orbit many believe that one launch did make it all the way around. Doubt any remain as space junk, though.

See here [strangehorizons.com] for one article, but others exist (try searching for: manhole nuclear space object).
The article ponders whether it is myth or not and provides a number of links to other sites *documenting* the situation.
But realistically, it depends on what you define as man made. Byproducts from many industrial products will certainly (at least some of them) escape the bounds of our planet due to issues such as wind, volcanos, etc... I'm certain that on a daily basis we throw off quite a bit of dna etc...
But somehow, a manhole cover seems fitting.

It's understandable that they wouldn't find the object though. They should have put a direction finding transmitter on it though.

I doubt they could have done that ca. 45 years ago.

I'm sure his definition of space junk is "human manufactured parts or materials which are currently orbiting the earth".
I'm fairly certain that you must be in orbit if you think that DNA is "space junk". Sheesh.

My pet peeve was the government abandoning the x-series projects, going to the dumb capsule idea. I think if we had just kept developing the "space plane" concept then, we'd be 20 years further down the road to space travel being even more normal than it is now, and a lot cheaper. I also think that yaeger was technically the first guy in "space", certainly close enough.

Neat young geekatroid story. Had one of the first "transistor radios", was also one of the school sliderule and busted briefcase nerds. During one of the earlier geminis, I got to monitor the "news" out on the playground with the radio,where the reception actually "received" -heh- then come in and get on the school PA system and give "updates" every 15 minutes. Nice assignment. Manned launches were always constant tv and radio coverage back then, pre-empted most all other programming. cool beans and stuff.
Early WW I & II planes? (Score:2)
I have heard specualation that some World War 1 (or maybe 2) planes flew too high and accidently entered orbit. Maybe there is a big updraft in the Burmuda Triangle! ;-)

No WW 2, much less WW 1, aircraft were capable of reching even a fraction of orbital veleocity.
Re:Impossible (Score:1)
You might want to relearn your fractions...
Anything that is capable of movement can travel at a fraction of orbital velocity. Take me for example. If we suppose that orbital velocity for me is 18,000 MPH, and that I can walk briskly at 3 miles per hour, then that means that I can walk at 3/18000 of my orbital velocity, which translates to 1/6000.
My car travels at approximately 80 MPH on the freeway, which works out to 1/225 of orbital velocity for a Honda Civic. Put in hi-octane and a good downhill stretch, and we might me able to get that up to 1/150th of orbital velocity.
See how easy math is?....

And for that matter, when did Sputnik de-orbit? Presumably it would have been due to traces of atmospheric drag, since there wouldn't have been anything resembling thrusters.
