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.

Niven may or may not have been aware of the really weird anomalous data on Mercury that the 3/2 synchronous rotation explained.
Earthbased radio astronomy measurements of the radio (thermal, they presumed, correctly) emission of the disk as a function of phase angle showed that the nightside subsurface was warm, as if the planet wasn't in 1:1 synchronous rotation, instead of at cryogenic temperatures. D'oh!... turnes out that side faces the sun half the time, too. |
