| .....Venera
8 was a Venus atmospheric probe. Its
instrumentation included temperature,
pressure, and light sensors as well as
radio transmitters. The spacecraft took
117 days to reach Venus, entering the
atmosphere on 22 July 1972. Descent speed
was reduced from 41,696 km/hr to about
900 km/hr by aerobraking. The 2.5 meter
diameter parachute opened at an altitude
of 60 km, and a refrigeration system was
used to cool the interior components.
Venera 8 transmitted data during the
descent and continued to send back data
for 50 minutes after landing. The probe
confirmed the earlier data on the high
Venus surface temperature and pressure
returned by Venera 7, and also measured
the light level as being suitable for
surface photography, finding it to be
similar to the amount of light on Earth
on an overcast day. |
