I have a two part question in reference to the answers provided for the linked question below:
The answer stated:
”Not only did they land near local noon for the best possible natural lighting but they included halogen lamps (that went unused thanks to sunlight)3.”
First, why was it necessary for the Russians to land at local Noon on those days? Venus is Sun synchronous, making only one rotation every 243 days. That’s longer than the 225 days it takes for Venus to travel around the Sun. If Earth only rotated once during it’s 365 day year, any spot on the planet that you chose would have 6 months of light, then 6 months of day. So, in the timeframe of the landings, there wasn’t a night and day like there would be on Earth. They could easily pick a spot with 6 months of constant light. Why was local noon a concern for them?
The second part to this question-
”On the other hand, they were using spherical entry capsules with no ability to steer during entry then parachutes in the higher altitude region of the atmosphere (where the wind speeds reach 100 m/s5) so it's possible they vaguely aimed at easy to hit (based on ballistic constraints) apparently flat regions then examined the radar maps closer for the areas where they actually landed.”
I remember the Venera Probes used 3 parachutes simultaneously to slow descent, at which point, the capsule detached from the parachutes and fell to the planet. This doesn’t make sense. The winds in the Venutian atmosphere reach 225mph and faster. That’s considerably faster than the 157mph winds of a category 5 hurricane. Parachutes do not functional well, if at all, in hurricane speed winds. How did they manage to successfully land? Also, I vaguely remember that the altitude at which the capsule detached from the parachutes was a considerable distance from the surface. Do you know the altitude? I’ve looked in every Venera photo that was made available, but I can’t find one that shows the parachutes- or burning/ dissolving remnants of- in the sky or on the ground in the distance. Clouds of sulfuric acid would not be good for parachutes, but we should still see something left of the chutes.
One last thing: I am pretty ignorant of E.M. wavelengths, so how did the Russians manage to get a radio transmission back out of the atmosphere, when we didn’t even have the technology to map the surface until 1976? We couldn’t penetrate the dense atmosphere. How did they do it?
I would greatly appreciate any knowledge you could provide on that subject. Please don’t take my question the wrong way. Although the possibility remotely exists that the landings were faked, I seriously doubt that they were. The US and Soviet Union were at odds and had just entered a space race at that time. We would have loved for them to fail. I don’t see the possibility of the US finding out that the Russians faked the landings, and not skewering them in the media and in front of the world. I just don’t understand how they managed to do it?
Thank you for your time, Matt Brubach
