Deep Space 1 Completes Comet Fly-by
Saint Aardvark writes: "All right...Space.com is reporting here that NASA's Deep Space 1 probe successfully made it through Comet Borrelly -- pretty good for a spacecraft using up the last of its fuel, 'way past its expected lifetime, doing something it wasn't designed to do'. About 30 pix are being downloaded right now, and there's a press conference planned for Tuesday. In the meantime, read NASA's press release here. Way to go, DS-1 and NASA!"

I wonder how close they were planning on getting to the comet?
It would be sweet for the group if the pictures of the comet were more impresive than the asteroid ds1 was supposed to fly by for the original mission.
anyways, right on nasa!

I must finish with a shameless plug for the exciting computer animation I created to illustrate CONTOUR's mission, available at the CONTOUR website
Here's an interesting thought..
Maybe the comet is giving off truckloads of Xenon gas..the ion engine aboard this spacecraft (or any spacecraft with a similar ion engine) could "draft" the comet, conserve its own fuel, and ride along with the comet to a particular destination before pulling off and resuming its travel... Sorta like gravitational assist without the gravity part.

So if there wouldn't have been any surprises, would that have been a surprise?

The is fscking ace. Real science is waaaay better than sci-fi. Check out yesterday's astro pic of the day for a sexy photo of deep space 1 at

The bit I like about this mission is that they didn't really expect success, but decided to go the whole hog anyway as ds1 is almost dead.
Earlier this year, I was somehow under the impression that this space vehicle was out of our solar system. I was wrong.
Here is a nice view of where DS9 actually is in relation to our solar system planets.
I am very concerned about these developments. Now that DS1 has completed its missions, I am suspicious that it will be sold on the black market where it will become...
...A TOOL OF TERROR!

Geez after this beer-brewing article I thought NASA had lost all the people who had some sense in them (no not technical). But I was wrong. Woohoo.. Rock on NASA

Guess I need to submit a bug report to KDE folks. The pic looks way off in Konqueror. Of course I've seen it a million times but its not good when many people won't be able to see this one and figure out what it is.
This is great for NASA and science in general! Its good to see probes being tested beyond their design goals; Space is full of risks and perils and it is good we are pushing the envelope. Hopefully they'll keep DS-1 around a while because just because its old, doesn't mean you throw it away.

Well, since we can't attack Afghanistan in through normal methods (http://slashdot.org/articles/01/09/22/228250.shtm l), I bet NASA's trying to use Deep Space 1 to direct the comet towards Afghanistan! Think about it...it would take out all those pesky caves....
...the countries of the Middle East continue to do nothing in the way of advancing science. However, the are still sucking money out of the ground in the form of a thick, black sludge.
Why do users with IDs under 100,000 or over 700,000 usually have the most worthwhile comments?
It cracks me up the way that whenever NASA is running out of funding for a mission, they come up with some daring plunge which is supposed to lead to the death of the spacecraft. Remember Galileo, which took a pass at Io and was supposed to be killed by the radiation? Well, it has been damaged by the radiation, but it keeps on ticking (and keeps on spending money :-)). Not that NASA is wrong to do this - you need to move on to the next mission some time, and trying a riskier mission to get some last data is a way to go out with a bang, but the part which is amusing is when they talk all about their gutsy move without saying that the probe would have been turned off anyway due to lack of money.
Iä. That was fun...
Iä! The hideous Tentacle Master has spoken! Obey or be destroyed!
While we in the technology industry have never really doubted NASA's ability, this shines good on NASA in the public forum. To me, many in the general public view NASA as something that once had a purpose, but now is struggling to get their missions to work right, etc. (which is far from the truth). But something like this tells the world "Hey, so we forgot to convert back to metric... everyone makes mistakes... look at this!". NASA is still very much an important entity. Look at all of the advances made because of the space program. If anything, hopefully this will serve to deter (if only a little bit) the budget cuts NASA has been facing as of late.
Just a thought...
NASA now have a policy of destroying their equipment at the end of missions. Otherwise they find that the budget for the mission gets extended and takes away from the other missions they want to fund. I got the impression that this was another 'let's see if we can kill this thing' mission.
Of course the operators usually try to arrange it that the thing makes it through somehow...

"Gravity is only a theory, not a fact!"What I thought was interesting when I saw the great episode on DS1 on "The Discovery Channel" was the navigation system. Aparently DS1 does most of the decision processes by iteself, and I might add that is quite a task when you think about it. After all there are no real landmarks or other solid navigational aids in space so it uses picture comparision on where it is and where to go next. This AI allows minimal amounts of people required to keep her running and if I remember right they only had about 7-10 guys in this room watching and codeing on Sun workstations. Sun?! No wonder all the manuvers they made were "risky" and no wonder they ran out of funds to keep her going. I wonder why they didn't use linux, or if they plan to in the future.
NASA has a few bits of eye candy detailing the position of DSA relative to Borrley, the position of DS1 relative to the sun, and two viwes of the position of Borrlley (1, 2). The image page is here; the DS1 page is here.
This is about the 3rd or 4th mission I've now heard of that goes off and does something beyond its "expected mission" or "expected lifetime". Remember the landing on Eros? The probe that rammed the moon? Sure they have screw-ups like the Martian lander, but you got to give them credit for all these extra missions they are accomplishing, especially considering their ever decreasing budget.
Vote monkeys into Congress. They are cheaper and more trustworthy.
What were the management and group/responsibility structure changes that were implemented to make this project succeed in such a wildly unpredictable way.

With the International Space Station (ISS) running continiously over budget, NASA is more or less forced to shut down a lot of science missions. In other words, saving 5-10 mil on science data analysis in order to raise the 5 billion a year they need to build, launch and maintain the orbital tin cans that is the ISS. The ironry is that there will be insuficient money or crew in the ISS in order to do much significant science there anyway for the next five years, at least. But, those congrisional districts and big comapanies that make and launch the stuff will be happy. Those have a bigger lobby group than 20 or 30 scientists who dedicate their life to analysisng the data.
NASA has already pushed out the Mars exploration program by another two years this week. The trouble is, they do that every two years.
In fairness though, saying goodby to DS9 in these circumstances is acceptable. Running out of funding may be sad, but running out of fuel, which it has, is not something you can fix. Only for the fact that they overfilled it at launce got it this far.

And sensors that monitor the ion propulsion were reprogrammed to listen for magnetic fields and plasma waves in and around the comet.
OK, that part is definitely cool. Whoever came up with that one deserves some credit.
sig fault
So the obvious conclusion is, stop paying NASA to do stuff! Things clearly work better when they're retasking existing equipment to do something else, preferably involving a crash landing. From now on, we should forbid NASA to build anything other than Earth-orbit satellites.
But once the satellites are in orbit, heck, anything goes! Put people on 'em and send 'em to Mars! Or maybe skim the solar atmosphere! How about sending them to the nearest star at 0.9c? Or why not the galactic nucleus? There may be no limits to the potential of this new "non-funding" technology!!
I know a few people with connections to JPL and IIRC this project was planned for failure--delays, cheap material, constant "redesigns", etc. But the engineers who worked on it were very resourceful and somehow managed to get the thing up (think Macguyver and crazy workarounds). Now NASA is exploiting DS1.
Kudos to the engineers who fought the good fight.
