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.

I don't have detailed numbers for you, but my gut feeling is that the proximity of the Sun is such, aphelion or perihelion, that you'd run into a similar harshness of environment (and need about the same level of protection) either way.
After all, what difference does it make if the heat outside is just about enough to melt lead, or just more than enough to melt lead? Well, except for maybe needing lead-pond floats on your spacecraft... though I will note that there is no evidence of liquid-ponding of *any* materials in the Mariner 10 images. -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain
