Years with LPL: 1996 to present


Dr. McEwen is a planetary geologist and director of the Planetary Image Research Laboratory (PIRL). He is working on several active spacecraft experiments, listed below.

His major research interest is understanding active geologic processes such as volcanism, impact cratering, and slope processes. He is PI of a proposed mission to Jupiter's hyperactive moon Io. For Mars and the Moon he is studying a broad range of topics in planetary geology. He is also pursuing studies and proposals for future missions and experiments at Earth and to Jupiter's moons Io and Europa.
