LPSC 2015: First results from Dawn at Ceres: provisional place names and possible plumes

Emily Lakdawalla • March 19, 2015 • 6

Three talks on Tuesday at the Lunar and Planetary Science Conference concerned the first results from Dawn at Ceres. Chris Russell showed a map of "quads" with provisional names on Ceres, Andreas Nathues showed that Ceres' bright spot might be an area of plume-like activity, and Francesca Zambon showed color and temperature variations across the dwarf planet.

Mini mission updates: Dawn in orbit; Curiosity short circuit; Rosetta image release; Hayabusa2 in cruise phase; and more

Dawn has successfully entered orbit at Ceres, becoming the first mission to orbit a dwarf planet and the first to orbit two different bodies beyond Earth. I also have updates on Curiosity, Rosetta, Mars Express, Hayabusa2, the Chang'e program, InSIGHT, and OSIRIS-REx.

Watch Ceres rotate: A guide to interpreting Dawn's images

Emily Lakdawalla • March 03, 2015 • 14

NASA held a press briefing on the Dawn mission yesterday, sharing some new images and early interpretations of them. I see lots of things that intrigue me, and I'm looking forward to Dawn investigating them in more detail. I invite you to check out these photos yourself, and offer you some guidance on things to look for.

At last, Ceres is a geological world

I've been resisting all urges to speculate on what kinds of geological features are present on Ceres, until now. Finally, Dawn has gotten close enough that the pictures it has returned show geology: bright spots, flat-floored craters, and enigmatic grooves.

Ceres coming into focus

Emily Lakdawalla • February 06, 2015 • 8

The Dawn mission released new images of Ceres yesterday, taken on February 4, when Dawn had approached to within 145,000 kilometers. More details are coming into view, and they're fascinating. For one thing, there's not just one white spot any more: there are several.

Ceres: Just a little bit closer (and officially better than Hubble)

Emily Lakdawalla • January 27, 2015 • 5

Last week's Dawn images of Ceres were just slightly less detailed than Hubble's best. This week's are just slightly better.

New Dawn images of Ceres: comparable to Hubble

Emily Lakdawalla • January 20, 2015 • 9

Dawn has captured a series of photos of a rotating Ceres whose resolution is very close to Hubble's, and they show tantalizing surface details.
