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.
At the Geological Society of America conference this week, Curiosity scientists dug into the geology of Gale crater and shared puzzling results about the nature of the rocks that the rover has found there.
Curiosity spent a total of four weeks at Confidence Hills, feeding samples to SAM and CheMin several times. On two weekends during this period, the rover's activities were interrupted by faults with the robotic arm. Curiosity drove away from Confidence Hills on sol 780, and is ready to observe comet Siding Spring over the weekend.
Today the Mars Orbiter Mission released a nice four-image animation of teeny dark Phobos crossing Mars' huge orange disk. Mars Orbiter Mission joins a long line of Mars missions that have produced images of Mars and Phobos together.
The biggest news on Curiosity of late is that the rover has drilled her fourth full drill hole on Mars! Drilling happened at a site called "Confidence Hills" on sol 759. But before she did that, she took a long series of amazing photos of rock formations at Jubilee Pass, Panamint Butte, and Upheaval Dome.
Ever since I first learned about the capabilities of Mars Orbiter Mission's small payload of science instruments, I have been anticipating one type of data in particular: global color views of Mars captured in a single 2000-pixel-square frame. Just days after entering orbit, Mars Orbiter Mission has delivered on that promise.
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.
