Launched in September 2016, this probe will arrive near the near-Earth asteroid Benou in August 2018, search Earth's Trojan asteroids and bring a sample back to Earth in 2023.

This NASA mission (from the New Frontiers project) aims to collect a sample of regolith on the surface of the asteroid 101955 Bénou (1999 RQ35) which is one of the most primitive asteroids (type B). This mission will measure the Yarkovsky effect, that is to say the effect of solar radiation on the orbit. A good knowledge of this effect will make it easier to protect Earth from the collisions of this type of NEO.
