NASA uncovers hidden water pockets on the moon that could be crucial for future missions

Water hidden in tiny patches on the moon could provide key access to drinking
water for astronauts on future lunar missions, according to NASA

Hidden pockets of water on the moon could be much more common than scientists
previously thought, and the discovery could have potential implications for
future lunar missions.

Researchers suggest that in some cases tiny patches of ice might exist in
permanent shadows no bigger than a penny.

They explored phenomena on the moon called cold traps, which are shadowy regions
of the surface that exist in a state of eternal darkness.

It is thought that many have gone without a single ray of sunlight for
potentially billions of years.

Now scientists say there may be a lot more of these nooks and crannies than
previous data suggests.

Paul Hayne, assistant professor in the laboratory of atmospheric and space
physics at University of Colorado Boulder, said: "If you can imagine standing on
the surface of the moon near one of its poles, you would see shadows all over
the place. Many of those tiny shadows could be full of ice."

Drawing on detailed data from NASA's Lunar Reconnaissance Orbiter, the
researchers estimate the moon could harbour roughly 15,000 square miles of
permanent shadows in various shapes and sizes.

According to scientists, these might be reservoirs capable of preserving water
via ice.

Prof Hayne added: "If we're right, water is going to be more accessible for
drinking water, for rocket fuel, everything that Nasa needs water for."

Previous research has reported signs of hydration on the lunar surface,
particularly around the south pole.

However, these detections are based on a spectral signature, at three
micrometres, that cannot discriminate between water and hydroxyl (oxygen bonded
to hydrogen) bound in minerals.

In one of two papers published in Nature Astronomy, Casey Honniball, from the
University of Hawaii, and colleagues analysed data from the Stratospheric
Observatory for Infrared Astronomy (SOFIA) airborne telescope that observed the
moon at six micrometres.

At this wavelength, they were able to detect a spectral signature of water that
is not shared with other hydroxyl compounds.

They found water is present at high southern latitudes.

The authors suggest the detected water is probably stored in glass or between
grains on the lunar surface that protect it from the harsh environment.

In the other study, Prof Hayne assessed a whole range of possible sizes for cold
traps, down to one centimetre in diameter.

The team found that small-scale micro cold traps - some just 1cm wide - are
hundreds to thousands of times more numerous than larger cold traps, and they
can be found at both poles.

The authors suggest that approximately 40,000 square km of the lunar surface has
the capacity to trap water.

Researchers say the findings indicate water is efficiently produced or delivered
on the moon by various processes, and is likely to be stored in the moon's cold
traps at both polar region.

The team pulled data from real-life observations of the moon, then used
mathematical tools to recreate what its surface might look like at a very small
scale. They say it is a bit like a golf ball.

However the researchers caution that they cannot prove these shadows actually
hold pockets of ice, and the only way to do that would be to go there in person
or with rovers and dig.

But they say the results are promising, and future missions could shed even more
light on the moon's water resources.

Prof Hayne said: "Astronauts may not need to go into these deep, dark shadows.
They could walk around and find one that's a metre wide and that might be just
as likely to harbour ice."
