Lucy in the Sky NASA

Extended operations at multiple targets, as Dawn showed us, are possible with ion propulsion. But we still learn much from flybys, something New Horizons reminded us with its spectacular success at Pluto/Charon, and again reminds us as it closes on MU69. Likewise, a mission called Lucy will visit multiple objects, using traditional chemical propulsion with gravity assist to achieve flybys of seven different targets. The destination: Jupiter’s trojan asteroids. With launch scheduled for 2021, Lucy’s will study six Jupiter trojans and one asteroid in the Main Belt.
