UA's Melosh: Are we all Martians?

UA planetary science professor Jay Melosh, who will be on National Geographic tv next week talking about asteroid impacts on Earth, will also be giving a public lecture about the possibility that life traveled from Mars to Earth on meteorite material blasted off that planet's surface.

Melosh will deliver the Blitzer Award Lecture, "Are We All Martians? The Meteoritic Exchange of Life Between Planets," at 4 p.m. Wednesday, Feb. 25, in Room 201 of UA's Physics and Atmospheric Sciences building, 1118 E. 4th Street. The talk is free and open to the public.
