I'm guessing this has been discussed before, but
with the new initiatives on solar sails and ion
propulsion drives, humor me anyway.
As opposed to trying to orbit and proof an entire

So.
What would be involved in "Man-Rathing" it?
Looks like Earth Orbit Rendezvous is back to stay, yeah?

Say shielding 90% of radiation was possible by using magnets. Would it then
be possible to go and do what ever me wanted using the ISS.?
Assuming it was fully equipped and it could then be done at a pace and all
the new cup and coming water reprocessing systems are put in place.?

The SpaceX website's August/September update says they have a Q1 2005
paid
flight, and that the Falcon I is on the launch pad at Vandenberg.
It's not clear, though, if the Falcon on the pad is the one launching

Has anyone here heard of a mass driver?
I believe it is basically a long, sloping track on which sits a
platform, atop which is the payload (with booster) that you wish to
launch. I also have heard that the platform would be accelerated down

I've come to this newsgroup for some help with a question regarding the
behavior of a billiard ball on a string which is rotating about a
central point. Since this is in some ways similar to a mass in orbit,
I'd like to ask for confirmation or rebuttal of this idea:

I have been very curious lately about the fuel cell technology, and I
am interested in trying out a few demontrations on my own.
I've found a few sites on the internet that sell Fuel Cell Kits, but
they seem to be pretty expencive considering they are very low power.

Does Cassini have enough propellant that it would be possible
to perform Titan orbit insertion (TOI)? If so, and if Cassini would
be placed on an orbit of Titan, what would be the scientific
benefits/drawbacks of the mission? It's clear that Cassini would

I am looking to pick up a space oriented educational DVD for my 10 year
daughter for Christmas.  Any recommendations?
Thanks,

About 10 years ago I was using a Mac and a program called Voyager II. It
was a great program, I still use it today on this ancient Mac laptop I got
off eBay. Also, I use USNO's Multiyear Interactive Computer Almanac
(MICA), on a PC. MICA is due for an update after next year. The ...

There's a cute illustration of the tendency for optical spysats
to have orbits optimized for, among other things, sun angle and
time of day at http://www.globalsecurity.org/military/world/ukraine/kiev-imagery-01.htm
Note that in the two pictures of Independence Square in Kyiv(*),
