NASA to Crash Galileo Probe Into Jupiter

to bad its life is over,nasa needs a spacecraft that can fly around the solar system and study moons & planets instead of constantly using these one shot attempts where everything is allways lost. an ion propelled planetary explorer or a nuclear propelled craft that can navigate the inner solar system or more. of course only after we find a easy way to get into space such as the orbital space plane.
maybe soon they can find ways to keep the bacteria out of space so we don't pollute space before we get to it.
anyway, 108,000mph is really fast!

Or maybe someting similar to this is how life began on Earth. You never know, putting those microbed into a suitable environment may be a good thing in reality.
It's playing God a little bit when you think of it that way, but who's to say that it's not what should happen?

I am ok with Galileo burning up. It was always planned, but I am really glad they they extended Hubble's mission. Wasn't it set for reentry in the next couple of years? I went looking for a link to post for you guys, and all I could find was it was pushed back to 2010. I guess I was busy when the news came out... Phew!
Phew!
Re: NASA to Crash Galileo Probe Into Jupiter
well, that might be fast - but it ain't ludicrous speed....
the speed of light is 173,688,900,000,000 mph
108,000 isn't even a significant percent of c.
But its still fast in human terms and its great to see that they're doing that to protect the Europa.

108,000 mph...that's wacky...

Re: Re: NASA to Crash Galileo Probe Into Jupiter
Maybe so, but they'd probably have the same effect if they tagged you playing Frogger in space...

ha, well, I'd prefer being hit by an object traveling at high percentages of c - cause the explosion would be much bigger

definition of c
Mr. A.,
I don't understand where you got the number 173,688,900,000,000 for the speed of light per hour.
My understanding is that light travels at 186,000 miles/sec in a vaccuum. So 186,000(miles per sec)x3,600(secs in an hour) equals 669,600,000 mph. That makes 108,000 mph a measurable fraction of the speed of light. Unless I am wrong (quite possible) 1/6200th of it.

Right. So if you are to be killed, you might as well be seriously killed.

Re: definition of c
ah, my bad - I found speed of light in metric and botched the conversion.
Still, 669,600,000 mph is quite a lot faster than 108,000 mph...
I was reading the article on this on CNN
http://www.cnn.com/2003/TECH/space/09/21/galileo.crash/index.html
fun quote....
"Since it left Earth in 1989, Galileo has managed to do quite a bit with a computer brain comparable to that of an Apple II."
