Brief updates on four ongoing missions: JAXA's Akatsuki and Hayabusa2, and China's Chang'e 3 and Chang'e 5 test vehicle. JAXA has articulated the new science plan for Akatsuki. Hayabusa2's ion engines have checked out successfully. The Yutu rover is still alive on the Moon, and Chang'e 5 test vehicle has successfully tested crucial rendezvous operations in lunar orbit.
The Dawn mission released new images of Ceres yesterday, taken on February 4, when Dawn had approached to within 145,000 kilometers. More details are coming into view, and they're fascinating. For one thing, there's not just one white spot any more: there are several.
Here they are, the first images of Pluto from the approach phase of the New Horizons mission. Science has begun; we're on the home stretch!
Today I'm excited to show you some previously unreleased images from Mars Orbiter Mission, containing Mars' moons Phobos and Deimos.
As I write this post, New Horizons is nearing the end of a weeklong optical navigation campaign. The last optical navigation images in the weeklong series will be taken tomorrow, but it will likely take two weeks or more for all the data to get to Earth. Two weeks! Why does it take so long?
Last week's Dawn images of Ceres were just slightly less detailed than Hubble's best. This week's are just slightly better.
Chiron, which is both a centaur and a comet, may also have rings.
The first results of the Rosetta mission are out in Science magazine. The publication of these papers means that the OSIRIS camera team has finally released a large quantity of closeup images of comet Churyumov-Gerasimenko, taken in August and September of last year. I explain most of them, with help from my notes from December's American Geophysical Union meeting.
Curiosity has spent the last two months completing a second circuit of the Pahrump Hills field site, gathering APXS and MAHLI data. The work has been hampered by the loss of the ChemCam focusing laser, but the team is developing a workaround. Over the holidays, the rover downlinked many Gigabits of image data. The rover is now preparing for a drilling campaign.
