In sci.physics, Rick Sobie
<rsobie@spamblock_telus.net> <3F4FEE60.D9793F8E@spamblock_telus.net>: Savings bonds holders, for one. Nuclear power is routinely used in deep space missions to the outer planets -- though not in the way you might think. Look up "Cassini mission" for details -- and the controversy generated as the flight plan, in order to save fuel, involved several flybys, including one that put the craft very near the Earth, stealing some of its momentum and worrying people that, had the NASA engineers goofed the same way they goofed with the Mars Climate Orbiter, it might have crashed into the Earth, spewing extremely toxic plutonium all over the place. The canisters are thick enough to survive reentry, they assure us. Let's hope we don't find out the hard way. In any event, it's well on its way to Saturn, as intended. [1] Assume ice block in near-Earth orbit. [2] Deorbit said block. [3] Watch block drop on head as high pressure steam. Next question? If you need them, I have detailed calculations on why one gets steam rather than klonked on the head by a deorbiting iceball. (It's an artifact of an argument debunking Ye Arke.) [.sigsnip] -- #191, ewill3@earthlink.net It's still legal to go .sigless. |
