What's New in Lunar & Planetary Science

NASA has chosen two new Discovery missions, one, Lucy, to explore six Jupiter Trojan asteroids, and the other, Psyche, to explore main belt asteroid 16 Psyche. For more information, see the NASA press release.

The European Space Agency's ExoMars 2016 mission reached Mars on October 19. The main engine burn to put the Trace Gas Orbiter into orbit around Mars was successful. Signals from the Schiaparelli lander were lost moments before the scheduled touch down at 14:58 UT Earth-received time (10:58 a.m. EDT).

The final burn to lower the Juno spacecraft into a 14 day orbit around Jupiter, scheduled in October, was postponed due to a problem with two helium check valves. For more information see the Juno news release. Juno remains in a 53 day orbit while the problem is being studied.
