Craters on Mercury are oases for water ice, organic molecules
Craters on Mercury are oases for water ice, organic molecules
http://arstechnica.com/science/2012/...nic-molecules/ The presence of water on Mercury had been suspected since as early as 1992, due to Earth-based radar reflection experiments. These measurements were ambiguous enough that more direct observation was desirable. Enter MESSENGER: the MErcury Surface Space ENvironment, GEochemistry, and Ranging probe, which has been orbiting Mercury since 2011. MESSENGER carries a variety of instruments for measuring surface features and magnetic fields, along with more ordinary cameras for imaging. The radar reflection study found that some of Mercury's ice is in the form of frozen ponds. Other ice—still detectable through scattered light and neutron emission—is covered in dark, highly nonreflective material up to 20cm deep. The researchers determined this dark layer contains far less hydrogen than should be present if it were a water-saturated material. Complex organic—meaning carbon-containing—molecules are both dark in color and relatively common components of asteroids, meteorites, and comets. |

Does Mercury have an atmosphere? Its only 30 million miles from the Sun I think Mafia NASA is fudging here.Why not find out the reason its magnetic field is only 1% of Earth's,for it has same type core? Well it does rotate very slow. Why is its orbit so elongated? How did it get so close to the Sun? Is its orbit getting smaller? Mercury looks very old with layers of lava all hammered out by comets,and meteorites. It has cracks that are almost 3 miles high. I'm surprised Mafia NASA does not claim that these are "Water Cracks" Sam keep in mind its almost as hot there as Venus (800F) Not water,but m guess is melted lead and tin. However with no atmosphere its cold on the side not facing the Sun for about 30 days Water big Mafia NASA lie They lie much to often,and are losing their conning of the tax payers Fact is people have lost there faith in our space program,when it got known about those $25,000,000 toilets,and Chinese used 10 cent Depends,and depends were so much lighter,and more dependable. Get the picture yet? TreBert |
