This, to me is VERY cool.
Spirit has been recieving enough solar power to allow for nighttime observing.
JPL has directed it to look up, at the sky..
Here is what Spirit saw:
The two moons of Mars Deimos, and Phobos passing overhead, in time lapse.
That's awsome! I didn't know that they an take pictures at night. The veiw of the night sky on Mars must be excellent with a thin atmosphere and no
clouds (excluding a dust storm).
