What's Up in the Solar System in October 2012

Posted by Emily Lakdawalla on 2012/09/28 05:27 CDT | 2 comments

Welcome to my monthly survey of the activities of robots across the solar system! Tomorrow is the equinox at Mars; both Curiosity and Opportunity will be spending the month actively analyzing Martian rocks. It'll be a less active month for Cassini, as Saturn passes through solar conjunction late next month.

IKAROS is alive! (Or: oh me of little faith!)

Posted by Emily Lakdawalla on 2012/09/11 12:27 CDT

I am rarely so glad to admit that I was wrong as when it's about the failure of a mission. Only last month, I speculated that IKAROS's mission was done. And now the news comes that IKAROS has been heard from -- twice! -- on September 6 and 8, 2012.

What's Up in the Solar System in July 2012

Posted by Emily Lakdawalla on 2012/07/02 11:50 CDT

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.

A theme song for IKAROS

Posted by Emily Lakdawalla on 2012/03/11 10:10 CDT

JAXA's solar sail mission IKAROS is still hibernating, and there's no way of knowing if the spacecraft will reawaken or not. They try to raise contact with the spacecraft once a month, with the last attempt being made on March 10; we can only wait to see if they'll succeed. What better time to release a theme song for the mission? IKAROS has always been even more full of personality even than other JAXA missions (which is saying a lot).

A new trick for IKAROS: Spinning the other way

Posted by Emily Lakdawalla on 2011/10/19 01:49 CDT

JAXA's solar sail demonstration craft IKAROS is still puttering along, 17 months after it launched, and its controllers back on Earth keep coming up with new things to try with it. I'm pretty amazed by the most recent trick: reversing its spin direction. This may not sound like a big deal, but it is, especially for IKAROS.

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.

Encouragement from space for Japan

Posted by Emily Lakdawalla on 2011/03/22 11:05 CDT

I saw this posted by @Akatsuki_JAXA (the Akatsuki Venus mission's official Twitter identity) and thought it was cute so I'm sharing it here.

What's up in the solar system in March 2011

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).

Posted by Emily Lakdawalla on 2010/10/13 05:07 CDT

This news is a little old but worth mentioning: On September 9, the Japanese solar sail mission, IKAROS, won a Web award in Japan for their work to publicize the mission via Twitter.

IKAROS' deployable camera captures perfect sail photos and animation!

Posted by Emily Lakdawalla on 2010/06/15 08:50 CDT

We've already seen IKAROS' view of its deployed sails from cameras attached to the spacecraft, but, in a brilliant idea, the Japanese built IKAROS with two deployable cameras that could view the thing from a distance.
