Moon & Mars

JimColyer	Date: December 26, 2006 @ 5:25 PM NASA will return to the moon by 2020 and build a permanent base by 2024. The base will be at the moon's south pole because it is sunlit three-quarters of the time. Solar energy can be used. The plan is for crews to eventually stay on the moon for periods of 6 months. It will be an international effort, with Europe, Russia and Japan. The mission goal is to set the stage for going to Mars. In 1980, I thought we would be on Mars in my lifetime. It will probably not happen. Space exploration is long term. It involves the whole human species. It may be the 22nd century before men walk on Mars. ASTRONOMY http://jimcolyer.com/papers/entry?id=2

They could put a science lab on the moon and grow cultures of microorganisms and see how they cope with long term life on a foreign planet.

Fraser	Date: December 27, 2006 @ 3:07 AM Entropy; 1. Thermodynamics. a. (on a macroscopic scale) a function of thermodynamic variables, as temperature, pressure, or composition, that is a measure of the energy that is not available for work during a thermodynamic process. A closed system evolves toward a state of maximum entropy. b. (in statistical mechanics) a measure of the randomness of the microscopic constituents of a thermodynamic system. Symbol: S 2. (in data transmission and information theory) a measure of the loss of information in a transmitted signal or message. 3. (in cosmology) a hypothetical tendency for the universe to attain a state of maximum homogeneity in which all matter is at a uniform temperature (heat death). 4. a doctrine of inevitable social decline and degeneration.
