2015 will be the Year of the Dwarf Planet, and you need to tell people about it!

Posted by Emily Lakdawalla on 2014/03/05 07:00 CST | 11 comments

I am very excited about 2015, more so than I have been about any year since I started working at The Planetary Society. Dawn will enter orbit at Ceres, and New Horizons, which will fly past Pluto and Charon. But if we want this kind of exploration to continue, I'm challenging you, dear readers, to tell the world why such non-planetary worlds are compelling places to go exploring.

Pretty pictures of terraced craters on Mars

Posted by Emily Lakdawalla on 2014/02/27 10:16 CST | 3 comments

Check out this unusual crater on Mars. It's not a very big one, less than 500 meters in diameter, and yet it has two rings. Most craters on Mars this size are simple bowl shapes. What's going on here?

It's happened again; I went into the Cassini image archive looking for something specific and wound up spending several hours playing with totally unrelated image data. Here are several beautiful images of the rings from the archives.

Curiosity update, sols 540-8: New rules and longer drives

Posted by Emily Lakdawalla on 2014/02/20 05:53 CST | 3 comments

Curiosity has tested a new driving mode -- backwards -- and achieved their longest single-day drive in three months. And they've committed to driving to the spot formerly known as "KMS-9," marking that commitment by giving it a name, "Kimberley." My route maps show you why Curiosity's views will be shifting, and Ken Herkenhoff's blog posts explain the daily activities.
