FL – Still silent after 100 days, NASA’s long-lived Opportunity rover has emerged as a tiny blip in a new view taken
from orbit as the global Martian dust storm that encircled the Red Planet and cut
off all communications with Earth since June, gradually subsides. The view has clarified just enough for the
golf cart sized robot to at last be seen again.
The question is
and remains- Has She Survived ? – to tell the tale of her harrowing ordeal under
the thick dust swirls causing no power generation from her life giving solar
arrays to recharge the batteries and thereby virtually no heat to keep her
fragile electronics and computer chips from cracking under the constant stress
of the unending and deadly frigid Antartic-like temperature climate for more
than 3 months!
“NASA still hasn’t
heard from the Opportunity rover, but at least we can see it again,” officials
said in a status update statement released today, Sept. 25.
“There is no signal from
Opportunity,” NASA Chief Scientist Jim Green told me in a recent interview.
Today NASA just released
a new but fuzzy picture of the 14-year old Opportunity taken just days ago by
the high-resolution camera HiRISE camera onboard
NASA’s Mars Reconnaissance Orbiter.
The HiRISE image, shown as the lead image above, was
captured from Mars orbit on Sept. 20, 2018 from an altitude of about 166 miles (267 kilometers) above the Martian
surface. The white box marks a 154-foot-wide (47-meter-wide) area centered on
the rover which is barely noticeable as a small whitish splotch against the dark
red contours of the Red Planet.
When the massive planet-encircling dust storm hit Opportunity had
been descending down and exploring Perseverance
Valley located along the eroded western rim of the gigantic 22-km diameter (14
mi) impact crater named Endeavour.
“A new image produced by HiRISE, a
high-resolution camera aboard NASA’s Mars Reconnaissance Orbiter (MRO), shows a
small object on the slopes of the Red Planet’s Perseverance Valley. That object
is Opportunity, which was descending into the Martian valley when a dust storm
swept over the region a little more than 100 days ago.”

commands it beams to the 14-year-old rover’ said NASA.
“The tau — a measurement of how much sunlight
reaches the surface — over Opportunity was estimated to be a little higher
than 10 during some points during the dust storm. The tau has steadily fallen
in the last several months. On Thursday, Sept. 20, when this image was taken,
tau was estimated to be about 1.3 by MRO’s Mars Color Imager camera.”
