Landing on an asteroid.
NASA's next mission is to survey and map 1999 RQ36 or Bennu, collect samples, and then return to earth in 2018. They want to collect said samples to analyze the content of the asteroid to see if asteroids could have had a hand in creating life on Earth. The mission should kick off in September of 2016 and will be the first to involve landing on an asteroid.
