Seven years ago this month, Spirit bounced down onto the surface of the Red Planet, rolled to a stop upright, and beeped home, ready to roll. Three weeks later, Opportunity not only bounced down safely and right into a small crater, but opened its "eyes" to see what the Mars Exploration Rovers had been sent to find signs that water had once flowed there.

A new update has been posted to the Stardust website: The spacecraft continues to operate as expected and all subsystems are healthy on approach to comet Tempel 1.

A press briefing was held at NASA Headquarters this morning to preview the planned February 14 encounter by Stardust with Tempel 1. There aren't often lots of questions from media after these "preview" briefings, but today there were zero. That's not good.

Today the 365 Days of Astronomy podcast aired my contribution, Unmanned Space Exploration in 2011, about what to look forward to in solar system exploration this year.

Stardust is healthy after performing a "cold boot" to clear a memory address problem (a "memory address latch-up") that occurred late last year and caused the spacecraft to go into safe mode three times.

There are two intriguing possibilities being discussed in the Japanese media for what to do with Akatsuki, a space probe in orbit near Venus with a fully functional, highly capable suite of cameras but a damaged main engine.

The Mars Exploration Rovers are wrapping up another year of exploring their seventh -- having experienced both the best of times and the worst of times: Spirit continued a 10-month struggle to endure its coldest, harshest Martian winter yet; Opportunity set a new record for driving despite an arthritic front wheel and a broken shoulder, putting more miles on her rocker bogie in 2010 than in any other single year.

The Mars Exploration Rovers (MER) forged on in November, their 83rd month of an expedition originally planned for three months: Spirit remained silent at Gusev Crater presumably still re-charging her batteries, as Opportunity roved through a field of craters pressing on toward Endeavour Crater, quietly claiming title along the way to being the first roving robot to drive 25 kilometers on Mars.

I couldn't believe these videos when I first saw them: five views from engineering cameras of important events in the Chang'E 2 spacecraft's journey to the Moon.
