At long last, on sol 526, Curiosity imaged the part of the weather instrument that was damaged during landing, but no obvious damage is visible, to me anyway. On sol 527 they drove even closer to Dingo Gap, with plans to drive onto the dune in the sol 528 drive.

Posted by Bruce Betts on 2013/12/04 01:17 CST | 3 comments
We present an update and a video about the successful design, construction, and testing in a vacuum chamber by Honeybee Robotics of a prototype PlanetVac system, a new planetary surface sampling technique, sponsored by The Planetary Society. PlanetVac is a reliable system that effectively vacuums up planetary surface materials.
Why are MAVEN and Mars Orbiter Mission taking such different paths to Mars?
Posted by Emily Lakdawalla on 2013/11/22 12:15 CST | 18 comments
Two spacecraft launched for Mars this month: Mars Orbiter Mission on November 5, and MAVEN on November 18. MAVEN is now on an interplanetary trajectory, while Mars Orbiter Mission is still in Earth orbit and will not depart for Mars until the end of the month. A lot of people are asking me: why the difference? Here's your answer, with input from Dave Doody.

Power From the Isotopes
The United States is trying to generate plutonium fuel for the first time in 25 years. Will it succeed?
Posted by Casey Dreier on 2013/10/29 01:21 CDT | 2 comments
We report on the current state of Plutonium-238 production in the United States, a crucial fuel source for planetary exploration spacecraft.
Posted by Van Kane on 2013/10/23 09:17 CDT
Planetary spacecraft originally tended to be large missions. However, technology is shrinking, and before the decade is out, I expect that we will have at least one planetary mission based on a CubeSat.
