This month (actually, today), Cassini had a relatively close flyby of Titan, and New Horizons will observe a very distant Kuiper belt object named 1994 JR1. Akatsuki has just fine-tuned its orbit around Venus, and Hayabusa2 has begun an 800-hour ion engine thrusting phase to steer it toward near-Earth asteroid Ryugu.

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.

ESA's ExoMars Trace Gas Orbiter and Schiaparelli lander are in the final preparations for a launch as early as Monday, toward an October 2016 Mars orbit insertion and landing in Meridiani Planum. Launch on a Proton rocket is expected at 09:31:42 UT Monday, March 14. A Breeze-M upper stage will send the spacecraft on to Mars, with separation at 20:13 UT.
