CAPE CANAVERAL, FL – A massive dust storm rapidly spreading across Mars since early June has forced a halt to science operations by NASA’s solar powered Opportunity rover - as day has effectively been turned into night thereby starving the spacecraft of life-giving power.
“Science operations for NASA's Opportunity rover have been temporarily suspended as it waits out a growing dust storm on Mars,” NASA said in a statement.
“A dark, perpetual night has settled over the rover's location in Mars' Perseverance Valley,” NASA reported on June 10.
CAPE CANAVERAL, FL – A massive dust storm rapidly spreading across Mars since early June has forced a halt to science operations by NASA’s solar powered Opportunity rover - as day has effectively been turned into night thereby starving the spacecraft of life-giving power.
“Science operations for NASA's Opportunity rover have been temporarily suspended as it waits out a growing dust storm on Mars,” NASA said in a statement.
“A dark, perpetual night has settled over the rover's location in Mars' Perseverance Valley,” NASA reported on June 10.
The 2018 storm is now far worse than the prior global dust storm that afflicted Opportunity back in 2007 and is centered over the rover – and covers about a quarter of the planet!
“The storm is one of the most intense ever observed on the Red Planet.”
The long lived robot was launched in 2003, landed in 2004 and has been making breakthrough science and exploration discoveries ever since during its utterly remarkable 14.5-year-long overland trek across the 4th planet from the sun.
“As of June 10, it covered more
than 15.8 million square miles (41 million square kilometers) – about the area
of North America and Russia combined. It has blocked out so much sunlight, it has
effectively turned day into night for Opportunity, which is located near the
center of the storm, inside Mars' Perseverance Valley.”

As a
result of the ever thicker swirling dust, Opportunity's power levels had dropped significantly thus requiring
the rover to shift to minimal operations with only limited communications every
few days to conserve power.
Power is also needed
to run the heaters that keep the vital electronic boxes warm and protect them
from deadly sub-freezing temperatures.
Opportunity’s twin
sister rover Spirit died in 2011 when the robots solar panels produced
insufficient power to the electronics box heaters because it was stuck in a
sand trap.
“Engineers will
monitor the rover's power levels closely in the week to come. The rover needs
to balance low levels of charge in its battery with sub-freezing
temperatures. Its heaters are vitally important to keeping it alive, but
also draw more power from the battery.”
The giant dust storm began June 1 and has been growing even
since in intensity and area.
By June 6 it had ballooned to more than 7 million square miles (18
million square kilometers).
The dust storm was first detected by the Mars Reconnaissance Orbiter (MRO) - another NASA spacecraft currently orbiting the
Red Planet and which relays a portion of
the science data back to scientists on Earth.
An impressive global map of Mars showing the growing dust storm – see lead image above - was
taken on June 6, 2018 by the Mars Color Imager (MARCI) camera onboard the MRO spacecraft.
The approximate location of NASA’s Opportunity rover at Endeavour
Crater is marked by a blue dot.
Opportunity is currently descending down and exploring Perseverance Valley located along the eroded western rim of
the gigantic 22-km diameter impact crater named Endeavour.
Although Opportunity was only warrantied
for “90 Sols” of operation, it is now enjoying its 15th year of
continuous operations of the frigid alien world.
“Perseverance Valley” is an
ancient fluid-carved valley “possibly water-cut” that could hold groundbreaking
clues to the potential origin and evolution of life on Mars – if it ever
existed.
As of today, June 11, 2018,
long lived Opportunity has survived over 5112 Sols (or Martian days) roving the
harsh environment of the Red Planet.
Opportunity has
taken over 228,771 images and traversed over 28.06 miles (45.16 kilometers) - more than a marathon.
