Help
the Stardust spacecraft capture comet dust
and bring it back to Earth! Test your comet
IQ in this interactive quiz and help Stardust
capture samples from Comet Wild 2. Each time
you answer a question correctly, Stardust
will move closer to the comet.
Using gelatin and metal pellets, simulate the
technique used by STARDUST for collecting comet and interstellar dust
particles with aerogel, a silica dioxide gel with the lowest density
solid known.
