Rosetta identifies five possible landing sites for Philae

Posted by Emily Lakdawalla on 2014/08/26 09:59 CDT | 8 comments

The Rosetta team has announced the selection of five regions on Churyumov-Gerasimenko that they will study as possible landing sites for little Philae. Now, as Rosetta surveys the comet from its second triangular "orbit" at an average distance of 60 kilometers, the mission will target these spots for extra attention.

Cool animations of Phobos transits from Curiosity

Posted by Emily Lakdawalla on 2014/08/25 04:41 CDT | 4 comments

Shooting video of a lumpy moon crossing the Sun and turning it into a giant googly eye is not a new activity for Curiosity, but I get a fresh thrill each time I see one of these sequences downlinked from the rover.

Curiosity update, sols 697-726: Mars thwarts driving and drilling

Posted by Emily Lakdawalla on 2014/08/22 04:24 CDT | 2 comments

The Mars gremlins really had it in for Curiosity this month. A computer glitch and slippery sand conspired to delay the rover's progress toward Mount Sharp. And shifting rocks proved unsafe for drilling. The rover will continue driving toward Mount Sharp, departing Bonanza King without drilling, skirting Hidden Valley along a plateau to its north.

Twinkling worlds in motion: New Horizons' first optical navigation images of Pluto and Charon

Posted by Emily Lakdawalla on 2014/08/07 02:31 CDT | 10 comments

What's that in the distance? A binary star? Those are two little round worlds dancing in circles, whirling around a point in space located between the two of them. It's Pluto and Charon, clearly separated by New Horizons' camera.

A new angle on Churyumov-Gerasimenko brings circular features into focus

Posted by Emily Lakdawalla on 2014/08/04 10:23 CDT | 4 comments

It's just two days now until Rosetta arrives in its initial 100-kilometer "orbit" of comet Churyumov-Gerasimenko, and the latest view from Rosetta's NavCam is fascinating. Circular features on the comet remind me of Tempel 1 as seen by Deep Impact and Stardust.

New Rosetta view of the comet - and a comparison to other comets

Posted by Emily Lakdawalla on 2014/07/31 03:02 CDT | 8 comments

Rosetta's view of the comet is getting better and better. Today they released a new image from the high-resolution OSIRIS camera, and it's a very fresh one, taken only two days ago. Distinct features are coming into view. And it's finally detailed enough for me to compare it to the five other comets we've visited in the past.
