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.

What's Up in the Solar System in July 2012

Welcome to my monthly roundup of the activities of our intrepid robotic emissaries across the solar system! Curiosity is about to land; Opportunity has rolled through sol 3000; Odyssey is back online, having switched to a spare reaction wheel; Dawn is now in High-Altitude Mapping Orbit 2; and Cassini is taking advantage of its newly inclined orbit to get spectacular series of images of Saturn's rings.

Latest report from Akatsuki failure review board

Posted by Emily Lakdawalla on 2011/07/02 08:07 CDT

JAXA held a press conference on June 30 about the latest report from the review board that is charged with finding out what exactly caused Akatsuki's failure to enter orbit at Venus, and what that implies for the possibility of Akatsuki to try again when it returns to Venus in 2015 or 2016.

What's up in the solar system in April 2011

Posted by Emily Lakdawalla on 2011/03/31 03:59 CDT

April 2011 will see MESSENGER begin the science phase of its orbital mission at Mercury, and should, I think, also see the start of Dawn's approach observations of Vesta. At Mars, Opportunity is back on the road again, rolling inexorably toward Endeavour. At Saturn, Cassini will continue its focus on Saturn and Titan science.

Posted by Emily Lakdawalla on 2011/02/28 02:43 CST

I don't think there's any question what the big event of this month will be: MESSENGER is finally, finally entering orbit at Mercury on March 18 at 00:45 UTC (March 17 at 16:45 for me).
