Curiosity update, sols 896-949: Telegraph Peak, Garden City, and concern about the drill

Emily Lakdawalla • April 10, 2015 • 1

Since I last wrote about Curiosity drilling at Pink Cliffs, the rover has visited and studied two major sites, drilling at one of them. It has also suffered a short in the drill percussion mechanism that presents serious enough risk to warrant a moratorium on drill use until engineers develop a plan to continue to operate it safely.

LPSC 2015: Aeolian Processes on Mars and Titan

Nathan Bridges • March 26, 2015

Planetary scientist Nathan Bridges reports on results from the Lunar and Planetary Science Conference about the action of wind on the surfaces of Mars and Titan.

A Sky Full of Stars

In pictures of the planets, the stars aren't usually visible. But when they do appear, they're spectacular.

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

Emily Lakdawalla • March 06, 2015 • 1

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.

Curiosity update, sols 864-895: Drilling at Pink Cliffs

Emily Lakdawalla • February 20, 2015

Curiosity's second drilling campaign at the foot of Mount Sharp is complete. The rover spent about a month near Pink Cliffs, an area at the base of the Pahrump Hills outcrop, drilling and documenting a site named Mojave, where lighter-colored crystals were scattered through a very fine-grained rock.

FOIA Request Sheds Light on NASA Mission Extension Process

Jason Davis • February 06, 2015 • 3

A FOIA request offers insight into NASA's planetary science extended mission review process, which seems, at best, confusing, and at worst—with adjectival ratings like “Very Good/Good”—arbitrary.

Flawed Beauties

More examples of imperfect--but tantalizing--images from deep space.

Curiosity update, sols 814-863: Pahrump Hills Walkabout, part 2

Emily Lakdawalla • January 21, 2015 • 5

Curiosity has spent the last two months completing a second circuit of the Pahrump Hills field site, gathering APXS and MAHLI data. The work has been hampered by the loss of the ChemCam focusing laser, but the team is developing a workaround. Over the holidays, the rover downlinked many Gigabits of image data. The rover is now preparing for a drilling campaign.

Curiosity results from AGU: Methane is there, and it's variable

Emily Lakdawalla • December 30, 2014 • 6

At the American Geophysical Union meeting, the Curiosity mission announced that an instrument had finally definitively detected methane in Mars' atmosphere. It exists at a low background level, but there was a spike to about ten times that, which lasted for a couple of months before disappearing. What that means is unclear.

HiRISE image coverage of the Curiosity field site on Mars, Version 2.0

Emily Lakdawalla • December 30, 2014 • 1

There have been tons and tons of HiRISE images of the Curiosity landing region, and it has taken quite a lot of work for me to find, locate, and catalogue them. This post is a summary of what I've found; after four revisions and updates, it's now version 2.0 of the list.
