Long-runout landslides (sturzstroms) are found across the Solar System. They have been observed primarily on Earth and Mars, but also on Venus, and Jupiter’s moons Io and Callisto. I have just published a paper about sturzstroms on Iapetus.

Curiosity has pulled up to the edge of Glenelg, its first destination within Gale crater.

Welcome to my monthly survey of the activities of robots across the solar system! Tomorrow is the equinox at Mars; both Curiosity and Opportunity will be spending the month actively analyzing Martian rocks. It'll be a less active month for Cassini, as Saturn passes through solar conjunction late next month.

In August, India's prime minister announced the intent to build and launch a Mars orbiter in time for the November 2013 launch window, an insanely fast schedule. The structure of the spacecraft has now been delivered.

I'm hosting this week's Cosmoquest Science Hour, and plan to take viewers on a virtual tour of those mountains on Curiosity's horizon, and show you where Curiosity is likely to go. Join me and Fraser Cain here at 1600 PDT / 2300 UTC Wednesday.

Piggybacked on the shuttle carrier aircraft NASA 905, Endeavour has departed Florida for the last time. Her journey will take her to Los Angeles, where she'll begin a new and different kind of mission at the California Science Center.

It's now the early hours of sol 44, and JPL held a phone briefing today with the latest news from Curiosity. She's now driven about 300 meters, and has stopped at her first science target, a rock the team has named for the late Jake Matijevic.

An amateur-processed mosaic of some intriguing-looking broken rocks along Curiosity's traverse. They were intriguing enough to photograph with the Mastcam -- but not enough to stop and check them out, as Curiosity has already rolled on.

Curiosity has completed Commissioning Activity Period 2 and is on the road again. I asked Daniel Limonadi to explain a couple of the photos of tests being performed on CHIMRA, and took the opportunity to ask him an amusing question that came up during a previous Google+ Hangout.

Fraser Cain and I had a wide-ranging conversation about Curiosity's recent activities on Mars during the Cosmoquest Astronomy Hour.

I am rarely so glad to admit that I was wrong as when it's about the failure of a mission. Only last month, I speculated that IKAROS's mission was done. And now the news comes that IKAROS has been heard from -- twice! -- on September 6 and 8, 2012.

Dawn's last images of Vesta peek into previously shadowy north polar territory. As the spacecraft leaves Vesta behind, its science team requests help from the public.

We're still working on migrating content from the old to the new website. This week, that means I am looking, one by one, through some great amateur-processed space images.

Opportunity stood down for nine days in early August as Curiosity landed and went through check-out, but on the tenth day the Mars Exploration Rover was back on the road, driving along the northwestern rim of Endeavour Crater and into the

Curiosity's much-anticipated self-portrait with the MAHLI camera just arrived on Earth, and even though it was shot through the dust cover it is AWESOME.

Oppy is opening an exciting new chapter in her adventure at Cape York. Having driven down to, over and past Whim Creek, she has now explored halfway down Cape York, to a promising fin-like ridge of dark rock.
