It seems like we’ve been preparing for the Phoenix mission for such a long time – and now it’s finally close to landing day! T-6 days according to our countdown clock! Things are getting pretty crazy here, and I thought a little overview of how the HiRISE team is supporting the Phoenix mission would be useful.

We’ve been imaging the northern plains for Phoenix since we started our mission (here’s a bunch of reconnaissance images on our website). The first images we got back showed lots of scary boulders (a close-up of one of our Transition images shown to the right), so we sampled other areas and searched for a relatively boulder-free landing spot. The area the Phoenix team finally chose is being called the “Green Valley“, not because of the “green light = safe to go” connotation, but rather because some geological maps made of the area happened to use green as the color for the valley. Perhaps coincidentally, Green Valley is also a town near Tucson, where both Phoenix and HiRISE are based. Whatever the reason, I like that the name has a lovely calm, comforting feel.

Once the Phoenix team picked out their landing site, we worked on a high-resolution mosaic of the entire 3-sigma landing ellipse (”3-sigma” means there is a 99% probability it will land within this area; see this great blog entry on landing ellipses at the Planetary Society). The Phoenix landing ellipse is shown to the left, along with the footprints of a number of HiRISE images. (This was before we were quite done with the mosaic.) These images have helped the Phoenix team characterize the regional geology and assess the safety of the landing site.

In addition to scouting landing sites, we’re also going to be involved with Phoenix during its prime mission on the ground. We’ve been planning and practicing several different ways of cooperating: (more…)

Tomorrow is the first launch opportunity for our sister mission, Phoenix. We don’t have a lot of day-to-day interaction with the Phoenix project, because their building is located a ways off-campus. It’s hard not to feel some camaraderie with them, though. Not only did HiRISE image a lot of possible landing sites, the mission is based right here in our department at the U of A.

If you aren’t super-excited about Phoenix yet, just try and not get excited by this awesome trailer they put together! (Alternate formats are available here, and on youtube, of course.) I was completely enthralled. It’s got everything — action, suspense, an emotional back-story, a totally Hollywood time-lapse mega-zoom to a night launch scene, and a rockin’ soundtrack!

The whole Phoenix website is fabulous, too, if you haven’t seen it yet.

Launches are risky times, and we’re all nervous and excited for Phoenix. All our best wishes go with it as it leaves this planet!

The 9 new images released yesterday are now also available with the Zoomify Flash applet.

This includes the first high resolution look near a candidate landing site for the Phoenix Mars Scout mission, which launches next year.

This is currently the best way for the ordinary computer user to get a good look at the detail in our images.

Stay tuned for more in the next few days!
