Okay...Like I was on militarynews.com and it turns out that China tested an anti-satellite missile. What's so amazing about an anti-satellite missile u ask? Nothing. But it just so happens that the floating debri is like this: a space shuttle going 3 times faster than the fastest bullet runs into a bunch of floating metal scraps...HUGE EXPLOSION, OR, Floating astronaut going 25,000 mph runs into a floating metal shard, astronaut dies...
So...Anymore tests and it wouldn't be safe to explore space...
WHICH MESSES UP MY PLANS OF DESTROYING HUMANITY AND STARTING A SPACE COLONY ON MARS
seriously not cool these communists are...
Space craft will be designed so that orbiting debris strikes a glancing blow and bounces off instead of piercing the shell.
New materials will further protect the craft from the debris. It would need to collect the energy from the impact and return that energy to the object to help the object bounce off without damaging the material.
Interesting that a saucer shape would probably be appropriate ...

HAHAHA
I knew those military people always exaggerate everything...
but the particles still pose a threat to astronauts, if they didn't then astronaut suits would be used in warfare...Red Alert !!!!!!!!!!! Shields Up !!!!!!!!!.......I think nasa were working on ( or at least talking about ) deflector shields for spacecraft based on knowledge gained from studying the solar systems heliosphere, I do remember though it would not stop a rock it was more of a radiation/cosmic ray shield.

Well the first computer was an abacus...In order to maintain an orbit at a particular altitude both the shuttle/astronaut and the debris would be going at the same speed. So its not like in the water where the debris is just floating there and you hit it at 25000mph - the differences in velocity will be much much smaller.

BUT what if they were going the opposite direction? PLUS the explosion accelerated them into *random* directions and *random* velocities...
True they could be in opposite directions - I'm not an expert but I'd assume that there is an international agreement as to which direction satellites are set into orbit (I seem to remember that due to the rotation of the Earth satellites have to go a certain way in order not to lose energy from travellign against the magnetic field?).
As you say the particles are given a random velocity in a random direction. The chances of the particles being given exactly the right velocity parallel to the Earth in order to maintain an orbit is extremely small. I'm sure it does happen but I can't imagine its as common as you would think.

Well actually its only near perfect circular orbits that are hard to maintain, elliptical orbits are rather easy...I just sent my observation report to Mars.
"There is no need to attack earth. These creatures will fight among themselves and finish each other. They have lot of space satellites and missile power. But it is directed against each other and not against us. So wait and watch. Soon this planet will be ours."

haha lol but we all know martians live underground near the ice and can't communicate because of their simple amoeba like morphology
Although it is likely one of these experiments (Such as the anti-satellite weapon) may cause small loss of life. I think that War will more likely be caused by traditional means. A war requiring a massive rebuilding scheme is due. There was only 20 years between WW1 and WW2 my Dad was only 18 in 1945 but his 80th birthday is due in December. We forget the hardships and the same things that caused war will cause them again.
American, Russian and European people, always have been testing their deadly weapons destroying ecosistem.
No, China is not OK, but you must see the whole thing.

Who said I liked America? lol
I hate America much more than China lolIt wouldn't necessary to use enough to cause an explosion, just either pierce the crew area, impact the heat shield, or hit the control systems like the OMS and RCS engines, hydraulics, or the control surfaces. Any of these could very likely bring down a shuttle.

Indeed...but...Since shuttles can with withstandand the intense heat of planetary reentry, it is unlikely that they would be damaged by a metalloid particle with a relativistic velocity of only a few hundred 100 kph...however, if there is no predefined orbital pattern that satellites must follow, then the speed on impact would be accelerated to 2500+originalexplosionspeedandvector
