This week MAVEN had to execute a short rocket burn in order to prevent a future collision with Phobos. Curiosity (and other rovers) may have played a role in those trajectory predictions.
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.
The MAVEN mission to Mars was just approved for a two-year extended mission that runs through September 2018. Now is a good time to take stock of we've learned so far and to describe the plans for the extended mission.
Welcome to my monthly inventory of the 20-plus spacecraft actively exploring our solar system. Highlights of this month include the impending launch of the ExoMars Trace Gas Orbiter and Schiaparelli lander, currently planned for March 14, and the resumption of regular VMC Mars images by Mars Express.
What's going on with our robotic planetary missions? In February I count more than 20 planetary spacecraft exploring six targets beyond Earth or cruising to new destinations.
I'm back from two weeks' vacation, so it's time to catch up on the status of all our intrepid planetary missions, from Akatsuki to the Voyagers and hitting the Moon, Mars, asteroids, comets, and Saturn in between.
It's been two weeks since comet Siding Spring passed close by Mars, and six of the seven Mars spacecraft have now checked in with quick looks at their images of the encounter. I round up all the results.
All seven Mars spacecraft are doing perfectly fine after comet Siding Spring's close encounter with Mars.
On Sepember 22 at 02:24 UTC, Earth received word that MAVEN had ended its orbit insertion burn on time, completing its journey to Mars. Today MAVEN has released some of its very first data, taken by the Imaging Ultraviolet Spectrograph just eight hours after arrival.
