Magnetic Properties

NSSDCA ID: 1975-075C-10

Mission Name: Viking 1 Lander
Principal Investigator:Dr. Robert B. Hargraves


The magnetic properties experiment detected the presence of magnetic particles in Martian surface material. It used three pairs of samarium-cobalt magnets, two mounted on the backhoe of the surface-sampler collector head and one on top of the lander. Each pair consisted of an outer ring magnet about 2.5 cm in diameter with an inner core magnet of opposite polarity. The magnets were directly imaged by the camera system in black and white and in color. A 4-power magnifying mirror was used for maximum resolution.
