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.

Up to now, there is no plan to land on Mercury but just to orbit around on the poles by the year 2011 . So the spacecraft must catch up the speed starting from 29.8 km/sec (relative to Sun) when it leaves the Earth and arrives at Mercury at 47.9 km/sec after one Earth Fly-by, 2 Venus Fly-By, and 3 Mercury Fly-By by March 18, 2011. Long trip! If you want to be closer to Mercury, start visiting at the following URL: http://messenger.jhuapl.edu/the_mission/index.html Nobody is thinking in exploring on Mercury. It is out of our present paradigma. The next time would be on Moon close to the year 2020 and maybe to Mars close to the year 2030. Rodolfo |
