This year will be another exciting one for space exploration. While 2014 will be remembered as the year we landed on a comet(!), 2015 may be known as the year of Pluto (and other dwarf planets). The New Horizons spacecraft begins its approach to Pluto this month, and will get closest to the dwarf planet in July, taking in the best view ever of the icy, remote world—possibly revealing a dramatic landscape with mountains, volcanoes, and geysers. In March, the Dawn spacecraft will arrive at Ceres, a dwarf planet in the asteroid belt between Mars and Jupiter. Ceres is another icy world, possibly with liquid water under a frozen surface, making it potentially habitable for life. Of course, that’s not all. The Rosetta mission will continue through the year and potentially beyond, making more discoveries as the spacecraft studies its comet up close. Despite tragedy and a rocket that exploded, private companies continue to push forward to make human spaceflight routine. Here are just a few of the highlights coming up in 2015 via WIRED.
