Space Shuttle Atlantis and her crew of 7 astronauts glided in to a smooth and triumphant touchdown today, Sunday, May 24.

Despite still being more than six years and just over 18 Astronomical Units from the Pluto system, the project team for New Horizons is conducting the second and final portion of our Pluto Encounter Preliminary Design Review (EPDR) tomorrow and the next day.

Today, I'm kicking the week off with a look at the unusually intense confluence of far flung planetary exploration that's just around the corner, starting the middle of next year.

The Spirit rover on Mars is currently stuck in a patch of loose material. After a few attempts to get free, the team has wisely decided to do further experiments on Earth instead of on Mars.

On Monday, if all goes well, we will launch the Space Shuttle to rejuvenate one the greatest scientific missions launched on or off the Earth: the Hubble Space Telescope.

The Mars Exploration Rovers challenged their ground crews with an April full of high drama, a little suspense, and a lot of energy. While Spirit lived through a kind of robot soap opera, complete with bewildering reboots and bouts of amnesia, Opportunity roved forward and back into the fast lane on a restored front wheel, slowing down for a brief visit to a series of small, intriguing craters and an unplanned close encounter with a pesky little purgatoid.

The upgraded Dawn spacecraft is now traveling in a new direction in its orbit around the Sun.

Perhaps what is most noteworthy and satisfying since the last log is not what Dawn did, but rather what it did not do.

The Mars Exploration Rovers logged a memorable March, with Spirit finally making some serious tracks and setting a new driving record for a five-wheeled rover, and Opportunity getting a first glimpse on the distant horizon of its next big attraction, Endeavour Crater as it crossed a geologic boundary into a new field of

Way to go, Spirit! The last two drives for the five-wheeled rover have taken it a total of about 40 meters west, traveling around the north edge of Home Plate. If I'm not mistaken, that's more than Spirit has driven in the last 400 sols combined.

The voting has begun to give the Mars Science Laboratory a genuine, non-acronym name!

Today we visited Grand Falls and the nearby dune field. Grand Falls is especially interesting because it combines many of the processes that are active in shaping planetary surfaces.

After a hectic week of tying up loose ends and running around like a chicken with its head cut off, I now have my proster done for the Lunar and Planetary Science Conference, and am in Phoenix for the Planetary Surface Processes field trip, led by my adviser Jim Bell.

Dawn swooped close to Mars and then left it behind on a new course, having taken advantage of Mars's gravity.
