It does not, it uses a battery.

Besides, the Soviets preferred solar panels over plutonium for their space probes. RTGs make sense in the outer Solar system where the heat is useful to keep the electronics at operating temperature. Venus is not that cold.

How does a thing that isn't water, 'water in the ocean'?

By not being made of water.

It can't land where there is no land, can it.

Are you going to ask next how a thing that isn't land can land on land?

Why do you think they can't use the radios on the Shuttle during re-entry?

I think that's because the Shuttle has been decommissioned in 2011.

The heat shield of the shuttle could withstand a temperate of up to 1533 Kelvin. That's a lot less that 3200 Kelvin. No wonder it exploded in 2003.

To be extra clear here, the shuttle's heat shield was made of silicium dioxide, and the melting point of silicium is 1683 Kelvin.

Nuclear power is the single most expensive form of energy. Nobody needs to oppose it, it is simply not economically viable. No nuclear power plant has ever made its money back.

Solar and wind are the cheapest and cleanest forms of energy, and those are being opposed, actively, by the oil lobby and the nuclear lobby. Yet they keep succeeding, because they are the cheapest and safest.

Why cheap, clean power is being opposed is no mystery.

53 years. And it was built to land on Venus, so it is almost certainly going to survive re-entry. There is a ~11/9 chance that it will water in the ocean, and it might survive that, too. Well, as much as a dead probe can survive, anyway. The parachute will probably not open, and most of the ocean is deep enough that the probe might not withstand the pressure.

This is exciting. Maybe they will collect it and display it in a museum? If they can find it. It is practically lost technology: When was the last time a probe was sent to land on Venus?

Yes, and they still measure their beer in pints, and occasionally body weight in stone.

That doesn't change the fact that they use the metric system in everyday life. Litres and centrimetres and kilogrammes and degrees Celcius.

Feet are still used for aviation (what a concept), but that is the case in most countries.

I guess switching all the road signs would be too much effort.
