They each weighed 380 kg. The solar panels provided 450 watts at Mars. The instrument payload was 59 kg. Telemetry channels were available at data rates between 8.33 and16200 bps. Both analog and digital tape recorders were used; the former handled television data only. Platform Descriptions ===================== The Mariner 6 and 7 spacecraft used a two-axis scan platform carrying the infrared radiometer, cameras, UV spectrometer, and infrared spectrometer. It was used to reposition the fields of view of the instruments repeatedly during the Mars flyby.
