There is no chance the rover will ever attempt to go down the crater for three very glaring reasons. Upper rims of craters are typically very steep,
vertical drops are common. If the rover survives that, the rims have lots of loose 'soil' and the little rover has very small wheels, in fact the
little rover is so small it would likely be half buried by the slope surface shake. The rover has very little torque but enough to dig itself in
(Spirit). Lastly depending on the position of the slope to the sun, the little rover could lose a lot of its solar power due to shade.
Curiosity is heading to the Gale crater with a plutonium decay RPG power system, to warm its scientific equipment and to have available power in the
shade, night, winter, virtually 100% of the time it is there, and the estimated half life of the unstable isotope can be 88 years.
A lot of people are unaware that the two rover power down for the duration of the Martian winters, which last about as long as an earth year.
Oh, the color of the Martian sky can vary depending on, amount of dust in the 'air', angle of the sun/season, and angle towards the camera.
