Spaceflight in 2017, part 2: Robots beyond Earth orbit

Posted by Emily Lakdawalla on 2016/12/30 12:22 CST | 4 comments

What's ahead for our intrepid space explorers in 2017? It'll be the end of Cassini, but not before the mission performs great science close to the rings. OSIRIS-REx will fly by Earth, and Chang'e 5 will launch to the Moon, as a host of other spacecraft continue their ongoing missions.

What's up in the solar system, November 2016 edition: Cassini takes a leap, ExoMars starts science, Long March 5 launch

Posted by Emily Lakdawalla on 2016/11/01 03:35 CDT | 2 comments

Cassini is going to make a major change to its orbit, getting much close to Saturn, setting up 20 "F-ring" orbits. ExoMars will get two science orbits before beginning aerobraking. Long March 5 will have its first launch, while many Earth-observing missions, including Himawari-9 and GOES-R, will go up. But Juno science is on hold.
