Planetary Scientist U.S.
Dr. Mark Hofstadter is a Planetary Scientist working at NASA's Jet Propulsion Laboratory in Pasadena, California. His research focuses on the atmospheres of planets, primarily the giants of the outer solar system (Jupiter, Saturn, Uranus, and Neptune). He is also involved in studies of comets, Venus, and looking for trace gases on Mars that could be a sign of life. Dr. Hofstadter uses both ground- and space-based radio telescopes in the course of his work. He is also the Lead Scientist for the Goldstone-Apple Valley Radio Telescope (GAVRT) program. GAVRT is a partnership between scientists and educators that allows middle- and high-school students to carry out real scientific research as part of their math and science classes.
MIRO (Microwave Instrument for the Rosetta Orbiter) is a scientific instrument on the ROSETTA Spacecraft.
GAVRT - Goldstone Apple Valley Radio Telescope
GAVRT teaches students to use radio astronomy, to control a huge antenna, and to collect science data from objects in the universe at which the antenna is pointed.
