There have been tons and tons of HiRISE images of the Curiosity landing region, and it has taken quite a lot of work for me to find, locate, and catalogue them. This post is a summary of what I've found; after four revisions and updates, it's now version 2.0 of the list.

It's been two weeks since comet Siding Spring passed close by Mars, and six of the seven Mars spacecraft have now checked in with quick looks at their images of the encounter. I round up all the results.

Some of Mars' most important secrets are hiding beneath the surface.

Comet Siding Spring is going to make a very close approach to Mars in October. Any comet dust that reaches Mars has the potential to inflict significant damage on the spacecraft orbiting the planet. As it turns out, however, Mars and its orbiters are likely to see very few, if any, impacts. Why?

Senior review recommends continuing all major planetary exploration missions, but not without some changes.

Now that we have reasonable confidence that our Mars orbiters will be safe from the close passage of comet Siding Spring, we are free to be excited about the opportunity that the encounter represents. At a community workshop on August 11, representatives from Mars missions shared their plans for great comet science.

Mars Express and Mars Reconnaissance Orbiter are keeping their eyes in the sky on Curiosity. There's a nice newly public color image of all of Gale Crater from HiRISE, and two new HiRISE images within the Curiosity landing site.

How I took a high-res photo of an intriguing spot on the Red Planet--and how you can, too.

Vignettes from dozens of LPSC talks: GRAIL and LADEE at the Moon; ice and craters and conglomerates and organics and gullies on Mars; polar deposits and volatile elements on Mercury; tectonics on Enceladus; and more, until my brain was so full I could barely speak.
