WASHINGTON: During 14 years of intrepid exploration across Mars,
it advanced human knowledge by confirming that water once flowed on
the red planet — but NASA’s Opportunity rover has analyzed its
last soil sample.
The robot has been missing since the US space agency lost contact
during a dust storm in June last year and was declared officially
dead Wednesday, ending one of the most fruitful missions in the
history of space exploration.
Unable to recharge its batteries, Opportunity left hundreds of
messages from Earth unanswered over the months, and NASA said it
made its last attempt at contact Tuesday evening.
“I declare the Opportunity mission as complete,” Thomas
Zurbuchen, associate administrator of NASA’s Science Mission
Directorate told a news conference at mission headquarters in
Pasadena, California.
The community of researchers and engineers involved in the program
were in mourning over the passing of the rover, known
affectionately as Oppy.
“It is a hard day,” said John Callas, manager of the Mars
Exploration Rover project.
“Even though it is a machine and we’re saying goodbye, it’s
very hard and it’s very poignant.”
“Don’t be sad it’s over, be proud it taught us so much,”
former president Barack Obama tweeted later on Thursday.
“Congrats to all the men and women of @NASA on a @MarsRovers
mission that beat all expectations, inspired a new generation of
Americans, and demands we keep investing in science that pushes the
boundaries of human knowledge.”
The nostalgia extended across the generations of scientists who
have handled the plucky little adventurer.
“Godspeed, Opportunity,” tweeted Keri Bean, who had the
“privilege” of sending the final message to the robot.
“Hail to the Queen of Mars,” added Mike Seibert,
Opportunity’s former flight director and rover driver in another
tweet, while Frank Hartman, who piloted Oppy, told AFP he felt
“greatly honored to have been a small part of it.”
“Engulfed by a giant planet-encircling dust storm: Is there a
more fitting end for a mission as perfect and courageous from start
to finish as Opportunity?” he said.
The program has had an extraordinary record of success: 28.1 miles
(45.2 kilometers) traversed, more than the Soviet Union’s
Lunokhod 2 moon rover during the 1970s and more than the rover that
US astronauts took to the moon on the Apollo 17 mission in
1972.
“It is because of trailblazing missions such as Opportunity that
there will come a day when our brave astronauts walk on the surface
of Mars,” NASA Administrator Jim Bridenstine said in a
statement.
Opportunity sent back 217,594 images from Mars, all of which were
made available on the Internet.

“For the public, the big change was that Mars became a dynamic
place, and it was a place that you could explore every day,”
Emily Lakdawalla, an expert on space exploration and senior editor
at The Planetary Society.
“The fact that this rover was so mobile, it seemed like an
animate creature,” she said. “Plus it has this perspective on
the Martian surface that’s very human-like.”
“It really felt like an avatar for humanity traveling across the
surface,” she added.
Opportunity landed on an immense plain and spent half its life
there, traversing flat expanses and once getting stuck in a sand
dune for several weeks. It was there, using geological instruments,
that it confirmed that liquid water was once present on Mars.
During the second part of its life on Mars, Opportunity climbed to
the edge of the crater Endeavour, taking spectacular panoramic
images — and discovering veins of gypsum, additional proof that
water once flowed among the Martian rocks.
Opportunity’s twin, Spirit, landed three weeks ahead of it, and
was active until it expired in 2010. The two far exceeded the goals
of their creators: In theory, their missions were supposed to last
90 days.
Today, only a single rover is still active on Mars, Curiosity,
which arrived in 2012. It is powered not by the sun, but by a small
nuclear reactor.
In 2021, the recently named Rosalind Franklin robot, part of the
European-Russian ExoMars mission, is slated to land on a different
part of the planet, raising the population of active rovers to
two.
