Space Forum / Space Science / April 2004

As I was looking at the pictures Opportunity was sending us I was
missing totally debris and ejecta  from the craters in this
valley.
I was thinking about an explanations :

In order to shake some dust off the solar panels, couldn't the rovers
traverse an incline and induce a vibration in the solar panels through the
actuators in the wheels or elsewhere?
And weather permitting, could the same wind that cleaned the surrounding

I must be missing something.  From the Earth Impact Effects Program
(http://www.lpl.arizona.edu/impacteffects/):
"The maximum Earth impact velocity for objects orbiting the sun is
72 km/s."

Its sol 108 and spirit hasnt taken any new pictures since sol 105, there
hasnt been any update for a for days either.  This doesnt look good, im
starting to think something might be wrong with the rover.
Any thoughts on this?

On Cassini's page I read:

In 1882 Dr William Harkness of the U.S. Naval
Observatory and the Astronomer who headed the
Venus Transit Committee made this wonderful quote
about the next transit:

I notice that sometimes the MER pictures apply a lens filter. Is there
a listing of the various filtration methods that are being applied?

(The relation to the optics group is that the proposal
discusses geometrical optics and asymptotic ray theory some.)
I'm currently editing my geophysics/applied math Ph.D. proposal
and would like comments back, preferably to my campus e-mail

I copied this photo to hard drive a about 10-15 days ago (guess).Can
someone tell me what direction we are looking in here ?  The Gusev
crater is in the distance background barely visible but is that the
Columbia hills in front of that ? I didn't know the ridge was that

Over on alt.planets.mars, where the 'unorthodox'
interpreters of the MER photos set up shop, there
are a couple interesting observations.
I would love it if I could get a clear explanation
