Apart from powering the instruments (and communication) some power is needed to heat some instruments to working temperature. Space is coooold... According to site only the ultraviolet spectrometers need heating.
You can read all about that on the SETI@home site. A lot of manmade noise has to be taken into account when looking at promising signals. So far every really interesting looking signal has turned out to be man made.
According to recent space.com article they expect Voyager to run out of fuel in 2020. Some instruments have already shut down because there is no longer enough energy available to heat them all, and still communicate with Earth.
Some more interesting stuff there too, appearantly the scientists do not agree yet about the meaning of the latest incoming data.
This myth made my ISP decide that they could no longer charge for extra ip's handed out to customers, they said they just didn't have enough. This was the only way that you were allowed to use more than one machine on the cablemodem. Now they've finally allowed using NAT... don't wake 'm up:)
Be careful when upgrading from older versions of OpenBSD, the upgrade procedure for i386 is a little bit more complicated than usual. As noted here and here. There's a document describing a possible upgrade path available from 3.3 to 3.4.
As I was lucky enough to run into this on a relatively new install I could just do a complete reinstall, but not reading the upgrade instructions can get you in a lot of trouble this time...:)
Objections to launch are weighed, and if necessary a launch will be cancelled. The objections this time seem to be concerned with the ability to live on the ISS. If life support systems fail, there's always the Soyuz escape vehicle available. There are different ways of looking at what is safe. Safe enough is what counts.
Well gee.. if the gas would stay below it wouldn't influence ships, now, would it? The Discovery thing that has been mentioned a couple of times already demonstrates it in a waterlaboratory. A model ship in water, gas bubbles up, big stink, momentarily less boyancy for the ship, ship sinks.
Why? He mentions cost. Obviously, for him, speed is more important than cost. Not everything can be sped up with caching. Your way of doing a peformance comparison has merit too, but it's a different test imho. Please forgive me if I misunderstood you:)
He doesn't leave them out. Two countries achieved it, USA and Russia (Soviet Union). Russia still flies, it's the US and EU spaceprograms that need more funding (and better financial management).
In contrasting the huge data output expected from MRO, Graf said while present Mars missions are returning terrific data, "they are sending it over the equivalent of a dial-up modem line."
"When we get to Mars, and at the planet's closest approach to Earth, we're going to be able to have the equivalent of two Digital Subscriber Lines (DSL). It's going to be an amazing amount of data coming back," Graf said.
You can get DSL with different speeds, so I think this statement is a bit ambiguous, but it still seems a lot faster than 128kbps dual isdn speed.
For those that only looked at the pretty pictures: Aerogel is used in the Stardust spacecraft, that is at this very moment collecting spacedust. On january 2nd 2004 it will fly past the comet Wild-2, and collect particles from the comet. And in 2006 the spacecraft will return to earth to bring back the samples.
And this is only one of the spectacular things that NASA is doing next year. There is also the Mars rovers mission, Cassini-Huyghens will arive at Saturn, and (hopefully) the Shuttle will fly again..
You could say that it was killed by the more advanced operating systems of last decade of the 10th century. This would be fair and reasonable.
DOS wasn't perfect, had issues with memory, very large filesystems were not supported, 1.0 did not even have directories and the available commands were a sorry bunch compared to unix, but to say that OS's from the Middle Ages were better is taking it a bit too far, IMHO.

Lighten up, will you?

Please mod parent up. That Centrifuge Module looks like very interesting research...

The American space program is alive and well. Ok, it could be better, but to say that it is shut down is just plain wrong.
You forget your reaction time :>
I'll just say I have more trust in NASA engineers than in someone that mentions ignorance and then manages to produce that horrible rant.
Ofcourse only the real diehards know it actually means IBM RePort Generator :)
Space.com had a nice piece about this too.

Hmmm... FLASHMOB!
