Stardust samples exceed expectations

I must partially agree with 125gJoe.

While it's probably impossible to have collected space bacterias or viruses out there, they may have brougth back poisonous materials or even fine dust that could cause respiratory problems.

In that picture no one of the scientists is waeraing at least a mask. What if one of them sneezes inside the canister? All the experiment would be ruined.

I believe that the picture shown is of two janitors opening the vaccum bag, or those scientists have no idea of what they are doing.
 
You are saying there's no chance they could have brought back something very destructive, and I don't believe that.

Joe, exactly in what possible scenario is comet dust possibly "very destructive"? Biologically (an active agent to take advantage of how our bodys works)? Poisonous (an inactive, inert chemical that interferes with how our bodys work)? Radiation (Some type of radiation that the capture team (who were wearing safety suits) could not detect?)?

What is the area that you are concerned with?

From everything I have studied is that the extreme vast majority of any possible life forms on any planet, or the such, have an extremely tiny chance of surviving in any other environment. Humans cannot live on any planet, moon, comet, asteroid in our solar system other than Earth without us greatly manipulating or shielding ourselves from it (Other solar systems are a great unknown, but the possibility is astronomically tiny of a complimenting environment). It is EXTREMELY doubtful that even the most hardy of any creature on Earth (big or microscopic) can survive on any planet, moon, comet, asteroid other than Earth in our solar system for even a few minutes at the best.

So if the idea that none of the life here can even hope to scrape by for even a very short while in any of the greatly diverse scenarios that our solar system can provide, in what scenario can comet dust (I.E. Ancient ice ball specks that was never in a life evolving/promising environment) present a danger that we can expect?

Not biological. No "blob" that eats humans like acid.

Complex compounds like poison? But happens to be specifically poisonous to our biological makeup? The lottery is a sure win compared to that. Times a billion.

Radiation? Measured and studied at landing. No lethal or dangerous levels found.

I can't think of a possible idea of reasonable concern.

That's it exactly.
Humans are very fragile, and to introduce some unknown particles, not only from that comet, but possible stray particles from elsewhere is reckless scientific practice.

Even though the Andromeda Strain is fiction, and you say any danger is very remote, why chance it?

That's my area of concern.

Also, patoloco brought up an excellent point! "In that picture no one of the scientists is waeraing at least a mask. What if one of them sneezes inside the canister? All the experiment would be ruined.

Seems like those "space particles" should not even be subject to a cough, for fear of ruining the experiment....

Maybe these photos are showing the "dummy" capsule. It can be proven that at least one hour of the recovery was not shown on the 'live video feed'. Maybe real precautions were taken on the other capsule...

:huh: Eh - no worries...
