List,
The cameras on MER Spirit did a lot of star images:
http://www.universetoday.com/33613/spirit-rover-begins-making-night-sky-observations/
Exposures were limited to a short period and, of course,
the camera couldn't slew like an equatorial mount, so
it's not deep-sky work and can only take images of the
bright stars.
Spirit also took fine images of the Martian moons;
there are a lot of nice pictures of Deimos and Phobos,
including the frequent eclipses, here:

Also, meteors in the Martian atmosphere but no comets!
Although a "local" phenomenon, there are lots of nice
clouds on Mars to watch (and take movies of) as they
drift along:

Many of the best cloud movies are by the Phoenix lander.
And, if you were ON Mars, you could watch the two bright
"stars" of the Earth and its Moon orbit around each other
every thirty days by the naked eye alone. From Mars, the
Earth is an "Evening Star" or "Morning Star" like Venus is
for us on Earth, and just as bright, often the brightest in
the Martian sky, and with that orbital star of its own.
Spirit took a picture of the Earth just after Martian twilight
on sol 63 (2004), the first picture of the Earth from the
surface of another world:

Although the Earth-Moon system had been photographed
from Martian orbit earlier:

That would be worth going outside to watch, even if it is a
little nippy at night on Mars.
Well, more than a little nippy.

The night sky on Mars is probably worse on average than on Earth. Our
atmosphere hardly attenuates the stars at all (less than a magnitude
at sea level), but Mars often has a lot of dust in the air, which
definitely blocks them.

Thanks for the link...Awesome!
Being that Curiosity is nuclear powered, I would love to see a night
panorama of the amount of stars that would be visible in the dark
thin
atmosphere.
