How will it be to make a manned landing at Mercury at its closest to the sun (perihelion) on its equator when the sun is in the zenith ,what are the dangers of a landing then? Do we need to be protected against the sunheat and radiation then? How strong is the heat and radiation of the sun then ,and is it dangerous when the solaractivity is high then? What kind of spacesuits do we need then? Better protected suits than we have used on the apollo moonlandings i think. Can you explain how a landing on Mercury will be when it is at perihelion and land on its equator with the sun directly overhead? I hope it will ever happen. Lets start discuss about it.

There was in another thread a discution on the possibility of a long lived Venus lander, understand a lander which would be able to withstand the tremendous heat on Venus. On mercury, the conditions are in fact easier, as there is not the tremendously oxydizing Venus atmosphere (but solar radiations instead).
The discutions revolved around things such as using high temperature semicionductors (there are many, even more than at current temperature) or more innovative things such as electrostatic micro-relays, or micro sized vacuum tubes (with performances comparable to transistors). With a few cheap experiments, we could quickly know if really an electronics working at 460°C is feasible. If yes, little development is needed, as most of the technology already exists. So the idea of a long lived lander on Mercury can be envisioned seriously, not just as a dreamy prospect. As I explained ealier, an orbiter around Venus with high resolution imaging and IR spectrometre mapping would be the very least to do. To have some small landers with seismometres and an isotopic analysis too. But, as Bruce Moomav explains above, we need several seismometres in the hot zone, not just on the poles. |
