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.

Historic 1st descent down Martian
gully. Panoramic view looking down Perseverance Valley after entry at top was acquired by NASA’s Opportunity rover scanning from north to south. It shows numerous wheel tracks at left, center and right as rover conducted walkabout tour prior to starting historic first decent down a Martian gully – possibly carved by water – and looks into the interior of Endeavour crater. Perseverance Valley terminates down near the crater floor in the center of the panorama. The far rim of Endeavour crater is seen in the distance, beyond the dark floor.

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.

Opportunity’s twin

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

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

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.

14 Year Traverse Map for NASA’s Opportunity rover from 2004 to
2018. This map shows the entire 45 kilometer (28 mi) path the rover has driven on the Red Planet during over during over 14.5 Earth-years (7.5 Mars-years) and more than a marathon runners distance for over 5115 Sols, or Martian days, since landing inside Eagle Crater on Jan 24, 2004 – to current location at Perseverance Valley at the western rim of Endeavour Crater. The rover reached Perseverance Valley in May 2017 and descended about halfway by June 2018. Its likely a water carved Martian gully. Opportunity surpassed Marathon distance on Sol 3968 after reaching 11th Martian anniversary on Sol 3911. Opportunity discovered clay minerals at Esperance – indicative of a habitable zone – and searched for more at Marathon Valley.
