Dawn has successfully entered orbit at Ceres, becoming the first mission to orbit a dwarf planet and the first to orbit two different bodies beyond Earth. I also have updates on Curiosity, Rosetta, Mars Express, Hayabusa2, the Chang'e program, InSIGHT, and OSIRIS-REx.

Mars Orbiter Mission Methane Sensor for Mars is at work

Posted by Emily Lakdawalla on 2015/03/04 10:50 CST | 5 comments

After several months of near-silence, ISRO's Mars Orbiter Mission has released on Facebook the first data product from its Methane Sensor For Mars. Don't get too excited about methane yet: there is no positive or negative detection. The news here is that the Methane Sensor for Mars is working, systematically gathering data. They also released several new photos of Mars.

Watch Ceres rotate: A guide to interpreting Dawn's images

Posted by Emily Lakdawalla on 2015/03/03 02:55 CST | 14 comments

NASA held a press briefing on the Dawn mission yesterday, sharing some new images and early interpretations of them. I see lots of things that intrigue me, and I'm looking forward to Dawn investigating them in more detail. I invite you to check out these photos yourself, and offer you some guidance on things to look for.

At last, Ceres is a geological world

Posted by Emily Lakdawalla on 2015/02/25 09:42 CST | 25 comments

I've been resisting all urges to speculate on what kinds of geological features are present on Ceres, until now. Finally, Dawn has gotten close enough that the pictures it has returned show geology: bright spots, flat-floored craters, and enigmatic grooves.

Curiosity update, sols 864-895: Drilling at Pink Cliffs

Posted by Emily Lakdawalla on 2015/02/20 06:59 CST

Curiosity's second drilling campaign at the foot of Mount Sharp is complete. The rover spent about a month near Pink Cliffs, an area at the base of the Pahrump Hills outcrop, drilling and documenting a site named Mojave, where lighter-colored crystals were scattered through a very fine-grained rock.

An active comet, from a distance

Rosetta has closed to within 50 kilometers of Churyumov-Gerasimenko, on its way to a very close, 6-kilometer flyby of the comet tomorrow. To prepare for the flyby, Rosetta traveled much farther away, allowing it to snap these amazing photos of an increasingly active comet from a great distance.

Cassini begins a year of icy moon encounters with a flyby of Rhea

Posted by Emily Lakdawalla on 2015/02/12 07:39 CST | 5 comments

At last! Cassini is orbiting in Saturn's ring plane again. I do enjoy the dramatic photographs of Saturn's open ring system that Cassini can get from an inclined orbit, and we won't be getting those again for another year. But with an orbit close to the ring plane, Cassini can repeatedly encounter Saturn's icy moons, and icy moon flybys are my favorite thing about the Cassini mission.

Rosetta shifts from sedate circular orbits to swooping flybys

Posted by Emily Lakdawalla on 2015/02/10 12:35 CST | 9 comments

For the period of time before and after the Philae landing, Rosetta was able to orbit the comet close enough that it was in gravitationally bound orbits, circling the comet's center of gravity. As the comet's activity increases, the spacecraft has to spend most of its time farther away, performing occasional close flybys. The first of these is at 6 kilometers, on February 14.

A new mission for Akatsuki, and status updates for Hayabusa2 and Chang'e

Posted by Emily Lakdawalla on 2015/02/09 06:32 CST | 2 comments

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.
