- Re: ISS till 2028?
no but spacewalking astronauts found a wrench jammed into the station,
it was deformed by impact, lost from mir or something.
it happened to hit a structural part of the station, if it had hit a
few inches away it would of caused a big hole and lost pressure.
call it what you want but its only a matter of time.

Even that is going to make one hell of a bang when it hits, if it's
something falling into Earth's gravity well rather than something in orbit.
The one thing you wouldn't want to hit in orbit is part of one of the
Israeli satellites that are launched into retrograde orbits, so your
impact speed could be up to around 36,000 mph.

What's odd about Discovery is that it's perfectly designed to generate
artificial gravity by spinning the whole ship around the center section
where the communication system is (as is shown in 2010) but it doesn't
do that. The reason Discovery looks the way it does in the 2001 isn't
about science, it's to resemble the skull and spinal column of an animal

Sooner or later, something is bound to hit something that's manned in

of space impacts of smaller sizes on stations and shuttles already.
