Regular readers of this blog will find the content of today's 365 Days of Astronomy Podcast familiar, because it's an update on what the solar system exploration spacecraft are up to, based on my monthly "what's up" updates.

April 2011 will see MESSENGER begin the science phase of its orbital mission at Mercury, and should, I think, also see the start of Dawn's approach observations of Vesta. At Mars, Opportunity is back on the road again, rolling inexorably toward Endeavour. At Saturn, Cassini will continue its focus on Saturn and Titan science.

The Mars Exploration Rover mission experienced a month of highs tempered by one haunting low as it neared completion of its 87th month of a three-month tour this month. While Opportunity wrapped up its work at the youngest, freshest crater the rovers have explored to date, Spirit remained silent as the point of maximum sunshine for the Martian year came and went, further dimming once high hopes that the rover would phone home and rove on as summer settled on the southern hemisphere of Mars.

Wednesday morning included some interesting conversations. Notably, I spoke with Pamela Gay, who is responsible for the MoonZoo citizen science program and who is presently working on developing a site through which the public will be able to help search for potential Kuiper belt objects for the New Horizons mission to encounter after the Pluto flyby.

Last week the Mars Exploration Rover team dumped another 90 sols' worth of data from Mars into NASA's Planetary Data System, the national repository for space mission data. As I did once before, I dove into this fresh pile of data to pull out Opportunity's color views of the distant rim of Endeavour crater.

The Mars Exploration Rover (MER) mission emerged from its third solar conjunction this month and, as March roars in, is embarking on its 86th month on the Red Planet. While Opportunity roved away from a surface target it had been studying at Santa Maria Crater and on to an intriguing blue boulder, JPL engineers on Earth stepped up their efforts to recover Spirit, which has been silent, ostensibly in hibernation mode, since late March, nearly one year ago.

There is a fascinating new page on the Mars Exploration Rover Pancam science team's website, full of color versions of Opportunity's microscopic images. The Microscopic Imager is one of the tools on the end of the robotic arm, and serves as a hand lens for the robot geologist to explore the rocks and sands of Mars in great detail.

It's always a relief when conjunction passes. Opportunity has gotten right back to work, sending down data acquired just before the moratorium, which spanned from January 27 to February 11.

Thanks to the work of several amateurs, Google Mars is a great tool for following the past and future peregrinations of the Mars Exploration Rover Opportunity.

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.

In a lovely talk, in his uncommonly engaging way, Steve Squyres presents the portrait of him that now hangs in the Smithsonian's National Portrait Gallery.

Mars Reconnaissance Orbiter has just snapped another photo of Opportunity sitting on the ground on Mars. These pictures never get old.

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.

Today Opportunity has driven to within 20 meters of Santa Maria crater, and the blocks around it are really, really cool-looking. This one is a dead ringer for the severed tail of an alligator.

Opportunity is on a kilometers-long eastward road trip across Meridiani Planum toward the rim of a large ancient crater named Endeavour; it'll be many months yet before she gets there.

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.

In the last few days, Opportunity's passed by several craters, and the rover drivers took advantage of the chance encounters for what they call "drive-by shooting" (a phrase I can't say I'm particularly fond of, but they didn't ask me).
