Spaceweather (www.spaceweather.com) is reporting a dust storm on Mars visible in amateur telescopes. Hope we don't get too much dust-fall on the solar panels.... unsure.gif

always a new twist for the programmers:

"...The morning after a deep sleep, the rover wakes up when solar panels start putting out a prescribed level of energy. However, a dust storm in the Meridiani region reduced sunshine enough on the morning of sol 628 that Opportunity did not wake from deep sleep early enough for the first scheduled activities of that sol. The rover's onboard software properly put Opportunity into self-protective automode for the day,..."

So the programmers now have to program in anticipation of the expected solar panel output as diminished by expected tau for the coming day.

Now that's a concept! Miss the alarm - so stay in bed for the day. I could work with that tongue.gif

FOR RELEASE: 9;00 am (EST) November 3, 2005

PHOTO NO.: STScI-PRC05-34a

MARS KICKS UP THE DUST AS IT MAKES CLOSEST APPROACH TO EARTH

NASA's Hubble Space Telescope snapped this picture of Mars on October
28, within a day of its closest approach to Earth on the night of
October 29. The large regional dust storm appears as the brighter,
redder cloudy region in the middle of the planet's disk. This storm,
which measures 930 miles (1500 km) has been churning in the planet's
equatorial regions for several weeks now, and it is likely responsible
for the reddish, dusty haze and other dust clouds seen across this
hemisphere of the planet. Hubble's Advanced Camera for Surveys High
Resolution Imager took this image when the red planet was 43 million
miles (69 million km) from Earth. Mars won't be this close again to
Earth until 2018. Mars is now in its warmest months, closest to the Sun
in its orbit, resulting in a smaller than normal south polar ice cap
which has largely sublimated with the approaching summer.

--------------------
"After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance.
I see that such intercourse long continued would make one thoroughly prosaic, hard,
and coarse. But the longest intercourse with Nature, though in her rudest moods, does
not thus harden and make coarse. A hard, sensible man whom we liken to a rock is
indeed much harder than a rock. From hard, coarse, insensible men with whom I have
no sympathy, I go to commune with the rocks, whose hearts are comparatively soft."

- Henry David Thoreau, November 15, 1853
