Descrizione:

Zond 2 was an automatic interplanetary station launched from a Tyazheliy Sputnik (1964-078A) in Earth parking orbit towards Mars to test space-borne systems and to carry out scientific investigations. The probe carried a descent craft and the same instruments as the Mars 1 flyby spacecraft: a magnetometer probe, television photographic equipment, a spectroreflectometer, radiation sensors (gas-discharge and scintillation counters), charged particle traps, a spectrograph to study ozone absorption bands, and a micrometeoroid instrument.
