A follow-up to How much more power does a PV cell generate in Venerean orbit?
NASA writes to say about Venera 8
... 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 with roughly 1 km visibility.
- Was this corroborated by other probes to Venus?
- Is the average intensity of sunlight (even through the overcast) adequate for a PV cell to supply power, or did any instruments work off the charge stored in batteries during descent?
