«To take the next really big leaps in lunar science is going to take landing on the ground and getting at it with instruments in a way very similar to what we've done for Mars,» says Barbara Cohen, a planetary scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, who has developed methods for dating planetary samples on the surface of other worlds1.
This is a new geological phenomenon, which doesn't happen on Earth, and could be vital to understanding similar processes on other planetary surfaces.»
In the search for other Earths, the main goal is to find a planet the same size as ours that sits in the habitable zone — the region around a given star where planetary surface temperature would be similar to ours, allowing liquid water to exist.
(The ESA spacecraft arrived at Sol's hottest planet on March 11, 2006, where it is being used to investigate how Venus — although similar to Earth in size, mass, and composition — evolved over the past 4.6 billion years to have atmospheric and planetary surface characteristics that now appear very different from those on Earth.)
I accept that there are complex weather systems bubbling away at any given point over the earth's surface but, on a planetary scale as the earth rotates on its axis, I suggest these will essentially average out, at similar angular distances as from the sub-solar point, at decadal and centennial timeframes.
Yet the period of rotation — obviously a major factor in explaining the loss of energy by a surface radiating to space — the Moon and Mercury for example have similar minimum temperatures — does not seem to have any place in this discussion yet it is one of the few real facts about planetary surface temperatures and heating and cooling we have.
