Mars dust storm clears, raising hope for stalled NASA rover

TAMPA, Aug 31, 2018 (BSS/AFP) – One of the biggest Martian dust storms on
record is clearing up after nearly three months, raising hope that NASA’s
stranded, solar-powered robotic vehicle, Opportunity, will soon come back to
life.

The US space agency’s 15-year-old rover was least heard from on June 10,
when it went into “sleep” mode as dust blocked out the Sun and darkness
enveloped the Red Planet.

A NASA statement issued late Thursday called the situation “critical,” but
added that “the rover team is cautiously optimistic, knowing that Opportunity
has overcome significant challenges during its 14-plus years on Mars.”

If no successful contact can be made, NASA says it will give up active
efforts in mid-October.

“If we do not hear back after 45 days, the team will be forced to conclude
that the Sun-blocking dust and the Martian cold have conspired to cause some
type of fault from which the rover will more than likely not recover,” said
John Callas, Opportunity project manager at NASA’s Jet Propulsion Laboratory.

“At that point, our active phase of reaching out to Opportunity will be at
an end.”

However, “passive listening efforts will continue for several months,”
Callas said, because of the “unlikely chance that there is a large amount of
dust sitting on the solar arrays that is blocking the Sun’s energy.”

Opportunity and its twin rover, Spirit, are a pair of unmanned robotic
vehicles designed by NASA to tool around on the Martian surface and transmit
data about conditions there back to Earth.

They landed on Mars in 2003 and were only meant to last 90 days and travel
1,000 yards (meters).

Spirit lasted 20 times longer than that. It became stuck in soft soil in
2009, and its mission was formally declared over in 2011.

Opportunity is going on 60 times its planned mission life, has traveled 28
miles (45 kilometers) and found evidence of water on Mars and conditions that
may have been suitable for sustaining microbial life.

And even though it is hobbled, having lost the use of its front steering
and 256-megabyte flash memory, not everyone is ready to give up so fast.

The hashtags #SaveOppy and #WakeUpOppy have gained popularity on Twitter,
with appeals to keep trying to contact the rover led by a former flight
director and Earth-based rover driver for Opportunity, Mike Siebert.

For Siebert, 45 days is too short, considering that NASA spent up to 15
months listening for contact from Spirit before giving up.

“100% Grade A B.S. the amount of time given to recover Opportunity is
woefully insufficient,” he tweeted late Thursday.

“Whomever made this decision is a coward.”
