    Today marks the 50th anniversary of Mariner 9 becoming the first spacecraft to orbit another planet! During its mission, the spacecraft mapped out 85% of Mars' surface, collected data on the composition of the atmosphere, and sent back over 7,000 photos.

    HiRISE 3D: A Gullied Crater As Northern Hemisphere mid-latitude gullied crater walls go, this is a nice one. At HiRISE full resolution scale, we can try to get a handle on distinguishing gullies formed by flowing liquid vs. dry mass movement.
