A flurry of press releases hit EurekAlert yesterday (one, two, three), indicating the release of a bunch of data from NASA’s Stardust mission. This is the probe that was sent out to fly through the tail of a comet, and catch tiny dust particles in an aerogel matrix, and return them to Earth for analysis.
The mission appears to have been a pretty impressive success, scientifically speaking, with a bunch of interesting findings relating to the age and composition of cometary material and interstellar dust. The full scientific results are released today in Science Express, and if you’ve got the inclination and an institutional subscription, should provide hours of interesting reading.
