Earth got a special delivery recently: a little pod plonked down in the Utah desert, containing a few hundred grams sampled from the surface of an asteroid. This isn't the first sample return mission, but it's definitely the biggest. The little parcel of asteroid dirt inside is now being very carefully handed out to researchers across the globe, and we're going to learn loads of important stuff, like what asteroids are made of, how we might stop one from hitting us ... and even, maybe, just maybe, whether they contain the building blocks of life.Help us make Syzygy even better!
