Over the weekend, a NASA spacecraft returned to Earth after a 7 year mission spanning nearly 4.6 billion kilometers. This spacecraft used a special substance to collect bits of comet Wild2.

1. Wat is the name of the spacecraft?
2. Wat is the name of the special substance on board the spacecraft used to collect the bits of comet Wild2?
3. Wat is the density of this special substance?
4. According to NASA, wat else can this substance be used for?

GOT ANSWERS! THX APPLESON AND TROPICAL STITCH FOR ANSWERS!
MODS CAN DELETE THIS THREAD

Well I'd help you with the answers but its to late. The only advice I have is going to ask.com

sorry I couldn't have been of more assistance

well, i think the name of the spacecraft was Stardust, but i'm not sure

1. Stardust
2. Aerogel
3. 3 mg/cm3 (cubic centimeters)
4. Thermal insulation of the Mars Rover and space suits.

I hope all these answers are correct! :)

for #2, i believe they used aerogel to collect the comet particles

Thx! I found a link now, but I have another question. What is the name of the space craft. Look at this quote from the link:
"The Stardust spacecraft's Sample Return Canister has arrived at.."
Is the name Stardust or Stardust Sample Canister? Because the title of link is Stardurst Sample Canister Arrives in Houston.

Thx Appleson! Just need to solve 3 and 4!

The canister SHOULD just mean that this is a specific part(an important part, or something that was in the ship that they were specifically talking about) of Stardust. I think it should just be Stardust :D At least, that's the way it looks to me :D

By the way, I just read what I said--did that make sense to you? It seemed kind of confusing the way I said it. LOL

Thx LaughSmile! Wow a lot of people are good at finding info about this lol

ok, if aerogel is the answer, then its density is 3 mg/cm3 (cm3 is supposed to be cubic centimeters, but i can't put the 3 as an exponent).

also, here's a link for the uses:

hola senor!!!

I finally finished my homework! Thanks everybody who helped me! Especially Appleson and TropicalStitch for proving answers for questions!
You rock!!

Thx LaughSmile! Wow a lot of people are good at finding info about this lol

You're welcome, I'm glad I could help :)
I like researching for answers. I didn't really research for these answers since other people did before I did, but I'm glad much that I helped you out :D
And I'm glad you finished your homework!!
