Kinetic energy is equal to 1/2 the product of the mass and the square of the speed. In formula form: Ek=1/2m*v^2

Even small things traveling really fast have a lot of energy. According to my calculations, a 1 gram particle, traveling at 36,000 mph has the same energy as a 3000 pound car traveling at 975 mph.

The shuttles had chips out of their windshields that NASA said were caused by paint flakes impacting at 36,000 mph.

No argument there.


Seriously!  Back when I was 19 - 20 I was working as a tech for McDonnell to pay for my BS degree (on the PGOC contract, payload ground ops) and was up on the white floor in OPF2 (I think it was) and they took me over and showed me a dime sized star crack apparently caused by a micrometeor. They said that the thing (looked like what you get on your windshield from a rock on the freeway) probably was a paint fleck sized bit of dust. Can't remember what orbiter it was, though. Probably the "Orbiter from Hell" (Columbia)... everything bad happened to it.

IIRC there was a payload which was orbited for a couple of years in the 80s just to test micrometeor and vacuum and rad damage. Long Duration Exposure Satellite or Facility or something. It was a horizontally integrated payload in the OPF before I started at KSC, though.

PS Live2Learn: thanks much! This is an interesting post and discussion.

Physics is stark.   We better not retire the VOR network.  No, not 'til there's a solid work around to physics.

>If< that's true, that's messed up, and you'd have grounds for a very sustainable complaint.

Proving that, however would probably be difficult absent someone(s) being very dumb.

If you worship the God of Abraham, don't apply to WV Wing. That's what I am getting out of this. I am not otherwise undesirable.

Any question. Any question at all. 42 is the universal ANSWER.

you gotta read the books....    ;)

And thanks for the fish!   ;)

Sigh. Brains the size of planets and we're reading Cap Talk... sigh...

Life?  Don't talk to me about life ...

Umm, yes. Commanders should find the "whys" and "what." I have no problem with that. But it appears that Mac wants to paint all transfers as "undesirables."
