NASA Overjoyed at Catch From Stardust
mknewman wrote to mention a New York Times report that the Stardust project has exceeded NASA scientist's expectations. From the article: "While they had expected mostly microscopic samples, the researchers said, a surprising number of the particles were large enough to be seen with the naked eye ... The cargo in the Stardust's sample container, which was opened Tuesday, 'was an ancient cosmic treasure from the very edge of the solar system,' Dr. Brownlee said. Scientists believe that these particles are the pristine remains of the material that formed the planets and other bodies some 4.6 billion years ago."
The cigarette brand West sponsored the russian cosmonaut training center in the 90s.
When the Russians delivered the supply module for the ISS, the rocket carrying the module had a "Pizza hut" logo on the side.
When MIR dropped into the ocean, Taco Bell placed a 40*40 feet large floating target in the supposed drop zone and claimed free Taco Bell for all US citizens if parts of MIR hit the target.
Maybe Hoover could sponsor NASA expeditions.

Well, at least this one didn't crash, explode, or get contaminated on impact. NASA 1, NATURE 8.
Congrats to NASA and their research team.
Really, what is this going to teach us? You can argue for funding NASA/space travel based on 'spin-off,' but come on...

It's excellent that we'll have a chance to study this material close up. Metorites are valuable, but this Stardust material is even more precious, because it will give us a look at unformed planetary material that was not likely ever part of a planetary body. Some of the meteorites we've studied may have been part of a smashed planet, or mal-formed planet, but comet material could have very interesting molecular structures I predict.
Saskboy's blog is good. 9 out of 10 dentists agree.
"...material that formed the planets and other bodies some 4.6 billion years ago."
I kind of thought we were standing on it.What steps has NASA taken to isolate the collected sample before analysis?
...some 4.6 billion years ago.
Of course they really mean about 6000 years ago.

This is great news! I love seeing space success stories out in the public eye. Perhaps such missions will be an inspiration to the next generation of potential explorers. There's just something cool about space...

Have so many been so excited about near invisible amounts of detritus. I've scraped more interesting stuff off of my shoes, today alone.
Rocket scientists are the most pathetic geeks of all.
If a 14-inch wide collector accumulated hundreds of humanly-visible samples in 195 days of travel - including at least one that caused a trace "large enough to put a small finger through", then any hope for high-speed space travel is really going to need excellent shielding. Statistically, it would seem very likely to encounter objects with sufficient mass to cause damage at high relative speeds. It might be interesting to see what a comparable flight through "clear space", and not near a comet would yield.
....it didn't asplode on impact and embarass them like the last model. Gotta hand it to NASA on how they keep the money doling interested. Here's a clue to the solar system: There's nothing there within our reach that'll save us when we finally fuck up the planet irreparably. Get over the concept that we could move and start trying to fix the Earth first.
Did anyone else have the mental image of an alien popping out of one of the lab techs' chest?
Now that NASA is overjoyed at playing Catch with large foreign objects, could they now clean their room?
They look great from my back yard. Just saw New Horizons go off and it was a blast :) Saw the last shuttle also. Now that I can see the rockets I have become a big fan of launches. So what about 1/2 billion here, 3/4 billion there. It's fun. Anyway, I don't where these scientists get their patience, New Horizons will take 12 years! Sheesh! Well between the billion dollar launches I shoot off vineger and baking soda rockets with my 5 year old. They are a lot of fun also.

With the all the recent news of organisms being able to survive in space, survive shuttle crashes, and all sorts of other crazy environments, we really ought to be careful what we bring back to Earth. I'm all for the advancement of science, and I think this particular experement is incredibly cool (both from a "what we can learn scientifically" standpoint, as well as a "holy crap, you guys were able to do WHAT??" standpoint), it'd really suck if we don't take the proper precautions, and wind up bringing back some organism that can wipe out all life on Earth. That being said, way to go NASA!

How can you blow up a comet to the core and expect to retrieve only a few microscopic samples, I wouldn't be surprised if they found a small boulder in that aerogel. They probably made their expectations really low so when they actualy saw the sample they would go "Oh wow, we never suspected that blowing up the comet would give us greater-than-microscopic samples".
I rest my case.
I mean, case closed.
NASA used the newer type of AeroGel to capture the dust particles. For those who don't know, AeroGel is an ultra-low density solid. The NASA AeroGel is an Alumina gel comprised of 99.8% air. The type that NASA used was Nickel-alumina, and they laced it with gadolinium and terbium so that space particles would cause the impact sight to glow under the correct conditions. (Some great photos of the foggy stuft at: http://stardust.jpl.nasa.gov/photo/aerogel.html)
Apparently, NASA is considering allowing civilians to search for space particulates through the web, scowering over hundreds of thousands of enlarged photographs. Its expected that NASA will announce plans for the program soon.

They didn't "blow up" anything.
All they did was fly in behind it.
ok. those are the large samples... if you want to help nasa (or nsa) compute the stardust microscope data (or echelon data) you can do that soon on Stardust@Home

A massive jello-like object was reported in downtown Houston today, reportedly devouring eveything in it's path and growing exponentially. When asked for comment, scientists at Nasa's Johnson Space Center had this to say:
"Hey, doesn't that look like that little booger-looking thing Johnson said he found in the Stardust Capsule?"
"What? I'm sorry, I couldn't hear you over the constant beeping of my bullshit detector..."
"Dr. Brownlee said some of the tracks in the aerogel might have been left by ice particles that later evaporated. If such cavities are found, he said, they may contain residue of the ice and its constituents." I wonder why they wouldnt have had the sample canister land in the frozen desert of Antarctica or some other area where ice samples would remain solid? Obviously they would stay cold enough during the return trip from the comet to preserve them, all it would entail is enough heat shielding to maintain the cold temperature during descent.
Too bad BHA isn't around to see this.

The spacecraft flew with a 14-inch-wide collector that resembled a tennis racket and was filled with aerogel, a silicon material composed of 99.8 percent air.
As I recall, space is a pretty good vacuum. Why doesn't the air get sucked out of the gel, especially if the gel is exposed to the vacuum of space and even more so if it is periodically being hit by particles?
Ok, maybe there wouldn't be one big "whooosh", but seven years is a long exposure.
Any ideas?

They were TRYING to collect samples. They flew it through the wake of a comet.
Don't judge the safety of space by a comet's wake, just like you shouldn't judge the calmness of the water while in the wake of a speedboat.
And why is NASA fishing there?

Along with that whole other , sending a probe to Pluto, mission. What differnece does it all make, except for being fuel for future quiz shows or board games. An object, traveling @ 56K mph for 10 years, to reach and take pictures of a place we'll never see or benefit from, is a colosal waste of time and money. Call me whatever, but I think those funds could go to something a lot more tangible, like education against supporting programs like this.
I know, its somewhat OT, but when will we start seeing this wonderful aerogel in civilian products?
---- Booth was a patriot ----
With the success of Stardust, Spirit, Opportunity, and other missions, NASA and JPL are clearly demonstrating that robots are aptly suited for productive space research. Rather than invest in the huge infrastructure required to support our frailty, we should accept that humans are not equipped for interplanetary travel and actively pursue new and imaginative unmanned missions.
BTW, Great job Stardust team. Congratulations! I can't wait to get my invite to help out!
Stardust was an superb mission considering the nice samples and clear images of Wild2 (almost an afterthought). The related mission Genesis has been out of the news after its hard landing, but apparently many of the samples are in good shape, too.
an ill wind that blows no good
I can't believe I didn't get on either of the name list microchips on this probe. Poot!
Fed up with slashdot? I am too.
Aren't comet's supposed to consist mostly of frozen water and gasses? Wouldn't most of that melt when exposed to earth temperatures?
I know they handle the sample in a very clean room, but shouldn't it also be very cold?
I've looked for mention of this in any of the articles, but haven't seen anything. So I'm probably misunderstanding something.
Ok, these "scientists" are spending 212 MILLION dollars of my tax money to get dust!?!? While i'm barely making it, living week to week. Who cares about the solar system and this shit. Everything I care or need to know about can be found in the old and new testament.
I heard Serena Williams was eaten in straight sets in Australia
"Seven Deadly Sins? I thought it was a to-do list!"
Other option is to put it back in its rightful environment, meaning send dust back in to space where it belongs.
I suggest you read Slashdot

While, I'd prefer to keep my money, if it is going to be taken from me (and legally I see no way out of it), I much prefer my money to go to something like this, than to "the poor".
I have no trouble finding charities of my own choosing. (My local homeless shelter gets most of my donations and volunteer time.)
Face it - if you make money some government is going to take some of it. That said, what do you want it to go to? Like I said, I can directly fund lots of charitable causes, but I would be hard pressed to fund real science.
This issue is a bit more complicated than you think.
i wonder if they are still using the 100 million dollar pen that writes in zero grav.. instead of a pencil...

The bad news is that there's a lot more big particles wandering around out there than they thought. Space is big. Really, really big. But you still don't want to hit something.
From TFA: "On its journey, the Stardust also spent 195 days collecting particles flowing through the solar system from stars far out in space. Scientists said there appeared to be hundreds of samples of these particles."

I'm not sure about the viability of NASA's expectation of finding stellar dust that's travelled from the outter edges of the galaxy and so on - there's already hundreds of years' worth of dust from grinding asteroids in our asteroid belt floating around here - and not to mention, the onslaught of comets that visit our system. Maybe it's just me, but I think it's highly likely that we'll just find the same stuff as we'd find in our backyard or on the moon.. In fact, if anything has a chance of having dust from the outter edges of our galaxy, I think it'd be the moon, no? Larger diameter than their collector, and millions of pits from meteors, some of which may be from the edge of the universe ;)
Just my 2 cents.
The wind god and the rain god and the thunder god and the fertility god obviously exist, by definition. (They are what causes these phenomena, which science can only partially explain).
I'm not sure about the upper case G gods. They were invented more recently. I'm not even sure how many there are - are the Xtian, Jewish and Islamic godz different?
To me they're all a big con game.
Hey, weren't they supposed to catch this probe by helicopter as it parachuted down to Earth? Seems like I remember reading about that, but I'm not sure if this is the same mission...
On Side A of the collector, the particles are from the comet. On Side B of the collector, the particles are from the cruise phase so that would be interstellar particles. However, none of this was "space junk".
So I was correct 2 out of 3 times.

About the opening of the sample, I suppose it's done in the best vacuum they can get. It's a logical assumption that they will do all the studies they can in vacuum, and if the samples are pressurized at all for some reason it will be in an inert gas.
