Opportunity's world of dunes and rock

Posted by Emily Lakdawalla on 2009/10/16 01:28 CDT

Opportunity's been making tracks lately, with brief stops to check out a couple of meteorites. I thought this view of its surroundings on sol 2,034 (a couple of days ago) was neat.

Changes in Titan's southern lakes

Posted by Emily Lakdawalla on 2009/10/06 05:19 CDT

Today's science press release out of the Division of Planetary Sciences meeting concerns changes in lakes near Titan's south pole observed during Cassini's mission. In brief, repeat Cassini RADAR observations of the same spots during different Titan flybys turned up places where there appeared to be dark lakes in earlier images and dry lakes in later images.

It would appear that Opportunity has stumbled upon another meteorite

Posted by Emily Lakdawalla on 2009/10/02 12:58 CDT

I wonder if this came from the same original body as Block Island, or if Meridiani is the kind of slowly deflating landscape that accumulates meteorites at its surface, like the ANSMET meteorite hunting spots in Antarctica?

Dust storm update: Skies clearing for Spirit

Posted by Emily Lakdawalla on 2009/09/02 12:25 CDT

For a while, Mars was beating Spirit while she was down, throwing a dust storm at the rover where it's bogged up to its hubcaps in fluffy soil When lots of dust is lofted into the sky, the hazard is that when it comes down, it may come down on the rover and its solar panels. But it appears things on Spirit are still pretty clean.
