Planet Kamchatka

Planet Kamchatka
Planet Kamchatka Lightning generated in a plume of ash strikes the volcano Tolbachik, while fresh and still incandescent ash glows on its summit. This volcano on the Kamchatka Peninsula erupted almost continuously from 1971 to 1975, laying down a carpet of ash that has proved to be excellent for testing the mobility of the Mars Rover. In August 1991 Tolbachik was visited by The Planetary Society's Mars Rover team and by a team of U.S. volcanologists. In this issue, we feature reports from both teams. V. Andreev
