Phoenix sent its first images of itself and Mars's surface, which indicate that all is well with the spacecraft. The lander is stable, the solar arrays have deployed, and Phoenix appears to be sitting on a smooth, landscape that is just what the scientists were hoping for. "It looks like a good place to start digging!" said Dan McCleese from JPL.
This image shows the lander's footpad planted quite nicely, not sunk into the surface at all. This indicates great stability for Phoenix.
Phoenix's solar arrays indicates that the arrays have deployed fully. Data indicates the batteries are fully charged as well, meaning the solar arrays are working perfectly.
