New Horizons was launched in 2006 to fly by Pluto and its moons. The unmanned spacecraft flew closest to Pluto on July 14, 2015. The craft will also study Pluto’s five moons: Charon, Nix, Hydra, Styx, and Kerberos. After its work around Pluto is done, it may investigate the Kuiper Belt.

Stardust was launched by NASA in 1999. Scientists sent it into outer space to collect samples from comets. So how did Stardust collect those samples? It contained plates of aerogel, a type of sticky stuff that attracted and kept the comet materials. It traveled three billion miles before returning to earth January 15, 2006, with samples it took from comet Wild 2.
