"This also means that water likely exists on Mercury and on asteroids such
as Vesta or Eros further within our solar system," lead author Yang Liu from
Tennessee said.
The moon has no such protection.S..NASA's robotic Lunar Crater
Observation and Sensing Satellite crashed into a permanently shadowed southern
lunar crater at 6,200 mph in 2009."Our work shows that the 'water' component,
the hydroxyl, is widespread in lunar materials, although not in the form of ice
or liquid water that can easily be used in a future manned lunar base," Michigan
geological sciences Professor Youxue Zhang said., Oct."Vesta is the second
most-massive asteroid in the solar system's asteroid belt between the orbits of
Mars and Jupiter.But they weren't sure how the water got there. 15 (UPI) -- The
moon is covered with soil containing a water substructure created by the
constant stream of charged particles coming from the sun, U.Scientists have
known for about five years that the traditional view that the moon was bone dry
was incorrect.Earth would receive the solar wind too, but its atmosphere and
magnetic field deflect it.
Eros is a near-Earth, Mars-crosser asteroid that the
NEAR Shoemaker probe observed in a 1998 flyby and in 2000 photographs before
landing on it in Tenn. researchers say.The substructure, known
as a hydroxyl, consists of one atom of hydrogen and one of oxygen, or OH, rather
than two of hydrogen and one of oxygen, or H2O, the researchers from the
University of Tennessee at Knoxville, University of Michigan and California
Institute of Technology reported in the journal Nature Geoscience. It could have
been indigenous or been a result of other sources, such as collisions from
water-bearing comets.The researchers concluded in the Nature Geoscience study
that positively charged subatomic hydrogen proton particles coming from the
solar wind -- a stream of charged particles ejected from the sun's upper
atmosphere -- appear to have combined with oxygen on the moon's surface to form
the OH hydroxyls. The crash -- equivalent to detonating 2 tons of TNT -- sent a
plume of material into the sky that scientists discovered was rich in water
ice.Spacecraft observations and new lab measurements of Apollo lunar samples
found icy drops of water on the lunar surface. "These planetary bodies have very
different environments, but all have the potential to produce water.The result
is an "unanticipated, abundant reservoir" of OH and water in Tilting pad journal bearing the dust,
soil, broken rock and other loose material on the lunar surface, the authors
wrote in the study, published online Sunday
