A batch of aerogel. Our photo doesn't do justice to how "ethereal" aerogel looks in real life. You can see through the edges and it resembles solid smoke.

Model of a radioisotope thermoelectric generator (RTG). RTGs contain Plutonium-238 and generate power for long-range space craft. The Cassini probe is currently in the Saturn moon system and is set to fly by Titan 14 in July. JPL scientists told us the

Dancing with satellites. JPL scientists show off their test "satellite" that simulates how satellites move in space. NASA is trying to build their Terrestrial Planet Finder which be five satellites flying in formation to form one giant telescope.

Compressed air shoots out the bottom and lifts the 800 lb satellite off the ground. JPL said the unit is only two hair-widths above the ground and can easily be pushed.
