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.

Here is one of the most beautifull photographs of Mercury i can found on the web Taken by the Mariner 10. Mercury was at near (ap)helion ,its greates distance from the Sun. You can see the sharp dark shadows on the picture. One thing is sure ,it will be hot on the dayside areas on the time the pictures were taken. I hope that the link works
