On sol 3425 Opportunity

Pay attention! This Mars orbiter, headed for launch in November, is a terrific science mission, as Mat Kaplan learned in a recent workshop, and in this week's Planetary Radio.

I noticed something funny while examining MAVEN assembly and testing videos.

Was there rainfall on Mars? Recent work mapping valley networks suggests there probably was -- but only for about 200 million years. What does this mean for life, and the Curiosity mission?

From sols 373 to 383 (August 23 to September 3, 2013), Curiosity traveled about 250 meters toward Mount Sharp over five drives, trying out her new AutoNav capability.

There wasn't a dull moment for the Mars Exploration Rover mission in August as Opportunity drove up to the base of the Solander Point section Endeavour Crater's eroded rim, crossed over a geological boundary between ancient eras, maneuvered through a boulder field, scooting unscathed from a near-miss with a rock that could have ended it all, and at month's end delivered her team to what looks to be another scientific gemstone on the Red Planet.

Those sneaky scientists on Curiosity managed to catch a Phobos transit of the Sun with one set of cameras, and to watch its shadow darkening the surface with another. COOL!

Opportunity arrived at the base of the next segment of the Endeavour crater rim and is now investigating the contact.

Yesterday, the Curiosity mission released the video whose potential I got so excited about a couple of weeks ago: the view, from Curiosity, of Phobos transiting Deimos in the Martian sky. In this post, Mark Lemmon answers a bunch of my questions about why they photograph Phobos and Deimos from rovers.

Yesterday was the first anniversary of Curiosity's landing on Mars, and there was much rejoicing. It's been fun to look back at that exciting day, and it's been an opportunity to reflect on what Curiosity has accomplished in her first year. What science do we have to show for it?

Observations made by the Mars Climate Sounder, an instrument aboard NASA’s Mars Reconnaissance Orbiter, have revealed new information about atmospheric tides on the Red Planet.

This week Opportunity finished up a quick investigation of the strange rocky terrain out here in the plains where it is approaching the next mountain rim segment of Endeavour crater, Solander Point.

It seems like it was just yesterday that 2000 people gathered in the Pasadena Convention Center to celebrate Curiosity's landing on Mars. All of Planetfest 2012 is online for your enjoyment.
