What's up in planetary missions in 2014

Emily Lakdawalla • December 31, 2013 • 4

With the New Year upon us, what can we look forward to in 2014? For me, the main event of 2014 is that ESA's Rosetta mission finally -- finally! -- catches up to the comet it has been chasing for a decade. We will lose LADEE, gain two Mars orbiters, and launch Hayabusa2. The year begins with an amazing 24 spacecraft exploring or cruising toward various planetary destinations.

Lunar Reconnaissance Orbiter spies Chang'e 3 and Yutu

LADEE has finally left Earth

Emily Lakdawalla • October 02, 2013 • 2

When LADEE launched on September 6, it launched into Earth orbit. Today, it is finally on a path that will take it to its October 6 lunar orbit insertion. Its operation is continuing normally in the face of the U.S. government's shutdown yesterday, as is that of Lunar Reconnaissance Orbiter.
