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 has been postponed due to a problem with two helium check valves. For more information see the Juno news release.

The Rosetta spacecraft completed its mission with a controlled descent onto the surface of comet comet 67P/Churyumov-Gerasimenko on Friday, 30 September, at 11:19 UT (7:19 a.m. EDT). For more information, see the ESA press release.
