Thomas A. (Tim) Mutch (August 26,1931 – October 6,1980) was an American geologist. He was a professor at Brown University from 1960 until his death. He was presumed killed when he disappeared during descent from Mount Nun in the Kashmir Himalayas .
He published two books about the geology of the Moon and of Mars. As head of the Viking surface photography team, he is quoted as commenting on the first pictures: "This is just an incredible scene. It looks safe and very interesting."
A crater on Mars was named in his honor, and the Viking 1 lander was renamed "Thomas A. Mutch Memorial Station" in 1982. The Thomas "Tim" Mutch Memorial Fund was established in 1981 by his family and friends.
