Venera 7

  1970-060A


V-70 No. 630 was the first of a pair of probes built for the 1970 window. It was the first to return data from the surface; it transmitted for 35 min during descent and a further 23 min after landing. It reported a temperature of 475C and a deduced pressure of 90 bar. Telemetry problems meant that only temperature was transmitted during descent. The parachute apparently failed a few meters above the surface. At first it was thought that no signals had been detected from the surface, since the antenna was pointed away from Earth, but a week later, after some processing, 23 minutes of data was extracted. The larger spacecraft mass required a more powerful booster, the Blok-NVL, with 140 kg more propellant than the Blok-VL.
