A plaque commemorating Thomas A. Mutch, former associate administrator of NASA's Office of Space Science, was unveiled in a ceremony at the National Air and Space Museum earlier this month. Mutch was lost while mountain climbing in the Himalayas in October (Eos, October 28, p. 693). The plaque will be affixed to the Viking 1 lander, renamed the Mutch Memorial Station, during a future Mars mission.

A follow-up Mars mission has been suggested for the 1990's, and although no funding is available now, there is talk, NASA says, of sending a roving spacecraft to Mars that would affix the plaque, scoop up some Martian terrain, and bring the sample back to earth. Until the plaque can be transported to Mars, it will remain at NASA headquarters in Washington, D.C.
