Spirit has landed successfully in Gusev Crater. Astrobot Biff has yet to check in, however, but he’s probably busy with post-landing checkouts.
Here’s the Yahoo! photo slideshow covering the landing and the first pictures.
Still waiting for word on Beagle 2, though.
(Seemingly lost in all the good MER news is the other good news that Stardust successfully rendezvoused with comet Wild 2 on Friday.)
