Bad news for Yutu rover

Posted by Emily Lakdawalla on 2014/01/25 05:33 CST | 8 comments

The Sun has set for a second time at Chang'e 3's landing site on the Moon. The lander is operating normally and shut down to sleep as expected, but the rover is not responding properly to Earth command so could not prepare properly for the oncoming lunar night, and likely will not survive it.

Dawn Journal: Planning for the Ceres Approach Phase

Posted by Marc Rayman on 2014/01/01 10:43 CST | 4 comments

Now more than halfway through its journey from protoplanet Vesta to dwarf planet Ceres, Dawn is continuing to use its advanced ion propulsion system to reshape its orbit around the sun. Now that the ship is closer to the uncharted shores ahead than the lands it unveiled astern, we will begin looking at the plans for exploring another alien world.

What's up in planetary missions in 2014

Posted by Emily Lakdawalla on 2013/12/31 01:15 CST | 4 comments

With the New Year upon us, what can we look forward to in 2014? For me, the main event of 2014 is that ESA's Rosetta mission finally -- finally! -- catches up to the comet it has been chasing for a decade. We will lose LADEE, gain two Mars orbiters, and launch Hayabusa 2. The year begins with an amazing 24 spacecraft exploring or cruising toward various planetary destinations.

Chang'e 3 update: 6 instruments active, new fan-produced landing video

Posted by Emily Lakdawalla on 2013/12/17 10:51 CST | 28 comments

Today there was a lengthy press briefing by several members of the Chang'e 3 science team. A complete transcript was posted in Chinese. I have run it through two machine translators and found it to be quite informative, not just about the mission but also about attitudes about Chinese space exploration and foreign cooperation. I also have a cool fan-produced video to share.
