NASA Science News for June 3, 2010

A Soviet robot lost on the dusty plains of the Moon for the past 40
years has been found again, and it is returning surprisingly strong
laser pulses to Earth. Researchers plan to use the aged robot to help
them measure the Moon's orbit and test theories of gravity.

Don't leave us in suspense, Sam! Is gravity still attractive, or has it
turned repulsive?

There is no such thing as gravity... the Earth just sucks... ;)

Now that is repulsive

What sort of surface accuracy do these corner reflectors have? Why is
there no degradation by the constant in-fall of high velocity space
dust, micro-meteorites, etc in an atmosphere free environment? The
incident surface must surely face "upwards" to some degree and cannot,
by definition, be protected. (or there would be no access)

They are typically prism based total internal reflection like cats eyes
or bike reflectors see for example

http://www.physics.ucsd.edu/~tmurphy/apollo/lrrr.html

So the front surface might get damaged and frosted losing some light to
scattering, but the rear surfaces that do the reflecting are protected.

Thankyou both. One might think that one could work backwards and use
the lunar reflectors as a test for the degree of microscopic
bombardment over time relative to a new prism. Of course it would be
very localised as dust might be "kicked up" by a slightly larger
particle landing close to the reflector. With the known tenacity of
lunar dust for clinging to every object were special precautions taken
by those who set them up manually?

Apparently it also makes our colorful moon into something
monochromatic.

Retard alert! Denialist level 6.

Worships at the altær of Photoshop cons.

Denies lunar footprints ere real.

No apology to the unbelievably brave people who went to the moon for
mankind?

Nope.

Still mal-lingering like a bad smell.

+Not that pathetic, no-hoper, BaRstwArD Guff.+

How often does the moon kick up dust from meteor strikes...seems a rarity to

bottom posting:
Solar storms can charge surface dust and make it fly around,
polluting mirrors etc.
And those solar eruptions occur quite often.
