Space Junk Threatens Space Station!, page 6

At least they were prepared for it lol, looks like the debris was a 13-centimetre-wide piece of a spent satellite motor called PAM-D. Interesting..

Hey, I liked those images you posted. Especially the second one...

(Determines to go and pick up that book "ring makers")


Edit - Good job with the story Phage!. S&F

It won't take long.
Give it 5 years.

Here is a short video of tracking the debris cloud from 1 of the recently destroyed sats.
Cosmos 2251. I have 457 NORAD radar tracked fragments loaded into Orbitron.

Hope you enjoy.


Peace

Indeed.

The volume of space in which asteroids reside is very much greater than the volume of space in which satellites (and their debris) reside.

I would have thought the ISS would have been a launching pad for any deep space exploration?

That was the initial "sales pitch" Reagan used to get approval of the public to support the expense for the ISS..the false sales lead promise of building a launching point to go back to the moon and byond.

Well, plenty of probes sent to Mars and even probes to orbit and take pictures of the Moon never launched from ISS at all.

ISS is basically an orbiting lab, a modern version of SkyLab and MIR. It has cansiter style moduels built by different nations participating in the ISS program. It simply orbits around the Earth, as the crews inside conduct various experiments done many times before on both the previous two space stations, SkyLab and the Russian MIR station, and even experiments that were done on early shuttle flight missions.

It is also a platform to study the long term effects of zero-G on humans....something again which was already done on SkyLab and MIR.

For one thing, we dont need study of zero G on humans because there are various artificial gravity systems that can be used to eliminate that problem, by simply rotating a section of a spacecraft or even a rotating section of the space station. Spin that up to the proper revolutions per minute and you generate an artificial gravity.

IMO, its really nothing more than a few assembled "coke cans" going in endless circles accomplishing things that have already been accomplished decades ago.

Maybe if they put an AG section on that station, and build more sections with AG, turn that thing into the first orbiting tour destination in space, it might then be useful.


Cheers!!!!

Well this is saying the debris was about a centimeter in size. Would a piece of debris that small cause them to evacuate? I wonder how fast it was moving?

...sad, but true. NASA probably says some true stuff, but it is a hard work to go through all their manipulations, lies and tricks, so even the science that they could share with us never really reaches us in pure condition. I am not sure about anything any more. The science they taught us at schools is in best case half truth. Which half? How to figure out garbage from true science?

Quite a bit larger than 1 cm and moving fast. Without knowing the vectors though, we can't know what the closing speed was.

In space, size doesn't matter too much after about 3 or 4 inches. Speed does. The object that put the scare into the space station was probably 5 inches, Matney said. McDowell figures it was even bigger, maybe a foot: "a long thin thing" with a thread or string attached. It was traveling 5.5 miles per second — about 20,000 mph, according to NASA spokesman Josh Byerly.
