Highlights this month include the impending arrival of Juno at Jupiter, the approval of extended missions for all of NASA's solar system spacecraft, and public data releases from Rosetta, New Horizons, and Cassini.

Today ESA released ExoMars Trace Gas Orbiter's first photo of Mars, taken from a distance of 41 million kilometers. It's no more detail than you can get through a pair of a binoculars, just a little taste of what's to come.

Curiosity is at a turning point in its mission to Mount Sharp, both literally and figuratively. Having drilled at three sample sites in 7 weeks, the rover took a left turn, changing its trajectory from a generally westward driving path to a southward one. It is now poised to cross the Bagnold dune field at Murray buttes.

Opportunity spent the first half of May digging into an outcrop, taking dozens of panoramic images from her site on the south wall of Marathon Valley at Endeavour Crater’s western rim, and basking in the Martian spring weather.

Curiosity has drilled into Mars for the 10th time at a site named Lubango, on sol 1320 (April 23, 2016). Lubango is in a bright-toned halo around a crack in the Stimson sandstone unit on the western edge of the Naukluft Plateau.

Curiosity has driven onward from Namib dune across a highstanding unit of rock called the Naukluft Plateau. Despite some frustrating sols lost to a short circuit in the RTG and DSN troubles, the rover has made progress, and performed lots of 3D imaging of weirdly wind-eroded rocks.

The ExoMars Trace Gas Orbiter and Schiaparelli lander are safely on their way to Mars! The two lifted off at 9:31 UTC today, March 14, 2016. Orbiter and lander will arrive at Mars on October 19 at approximately 16:00 UTC. The lander is expected to last about 3 days. The orbiter will spend a year aerobraking before beginning its science mission.
