The Mars Exploration Rovers Update: Opportunity Presses On in Perseverance, Pace Picks Up
In the west rim of Endeavour Crater, Opportunity continued her exploration of Perseverance Valley in March.
The Mars Exploration Rovers Update: Opportunity Logs 5000th Day, Snaps Selfie, and Roves On
When Opportunity’s 5000th day dawned in February, it was a meaningful milestone for the team, and it led to a personal first for the veteran robot field geologist that has chalked up so many firsts she’s set the standard for Mars rovers.
Opportunity's sol 5000 self-portrait
Last week the Mars Exploration Rover Opportunity celebrated its 5000th sol on Mars, and it celebrated by taking the first complete Mars Exploration Rover self-portrait.
The Mars Exploration Rovers Update: Mission Completes 14 Years of Exploring, Opportunity Roves into Year 15!
In January, Opportunity quietly completed 14 years of surface operations on Mars—the longest-lived robot on another planet.
The Mars Exploration Rovers Update: Opportunity Beats Winter, Wraps 2017, and Heads for 14th Anniversary
With the Martian winter on the run, Opportunity cruised closer to its 14th anniversary of exploring the Red Planet in December as she deliberated a distinctive “fork in the road” deep in Perseverance Valley and wrapped another record year.
The Mars Exploration Rovers Update: Opportunity Returns Fundamental Finding in Perseverance, Cruises Through Winter Solstice
Opportunity continued the historic winter science campaign inside Perseverance Valley and delivered the goods that confirmed an important discovery in November, and then cruised through winter solstice, driving the mission closer to its 14th anniversary of surface operations coming up in January.
The Mars Exploration Rovers Update: Opportunity Pops Wheelies Over Etched Rocks in Perseverance
As brutally cold got even colder at Endeavour Crater in October, the depths of winter gripped Opportunity, and ‘life’ on Mars slowed. But the robot field geologist continued to work on through the doldrums of the season.
Mars Exploration Rovers Update: Opportunity Braves Onset of Winter to Picture Perseverance
The Martian winter began to grip Endeavour Crater in September, slowing Opportunity's pace. But she braved the brutal cold in Perseverance Valley and followed her commands to visually document everything in sight.
Field Report from Mars: Sol 4857
Opportunity is continuing its drive down Perseverance Valley, a possible channel that was cut in the inner wall of the 22 km-diameter Endeavour impact crater on ancient Mars.
Mars Exploration Rovers Update: Opportunity Ventures Deeper into Perseverance
Along the western rim of Endeavour Crater, Opportunity forged onward in August vicariously taking the Mars Exploration Rovers team – along with a global contingent of mission observers all around Earth – downhill into Perseverance Valley and deeper into a new chapter in this legendary expedition of the Red Planet.
Mars Exploration Rovers Update: Opportunity Enters Perseverance Valley, Settles in for Solar Conjunction
After struggling to get her left front wheel unstuck in June, Opportunity quickly adapted to a new driving strategy and unabashedly cruised into Perseverance Valley in July.
Field Report from Mars: Sol 4782
With the latest drive on sol 4782, Opportunity began the long drive down the floor of Perseverance Valley here on Endeavour Crater.
Mars Exploration Rovers Update: Opportunity Sprains ‘Ankle’ but Perseveres on Walkabout
The autumn skies over Endeavour Crater remained hazy as dust from the summer storms continued to rain down, but Opportunity encountered some unexpected and serious June gloom when her right front steering wheel jammed during the walkabout atop Perseverance Valley.
Field Report from Mars: Sol 4766
Opportunity is doing a geologic walkabout at the entrance to Perseverance Valley, an ancient and potentially water-carved feature.
Mars Exploration Rovers Update: Opportunity Shoots the Moon on Arrival at Perseverance Valley
In another dynamic demonstration of what can be achieved when a team works together, Opportunity cruised to the top of Perseverance Valley, shot the moon, and drove into her 160th month of surface operations in May.
Field Report from Mars: Sol 4734
Opportunity has arrived at the head of Perseverance Valley—a possible water-cut valley.
The Mars Exploration Rovers Update: Opportunity Closes in on Perseverance Valley
Opportunity spent the month of April 2017 outside the western rim of Endeavour Crater, cruising toward Cape Byron and Perseverance Valley, the centerpiece of its tenth extended mission.
Field Report from Mars: Sol 4718
Opportunity has made the final drive in the month-long process that began way up north inside Endeavour Crater earlier this Earth-year.
Mars Exploration Rovers Update: Opportunity Dodges Dust Storms, Makes Tracks to Perseverance Valley
After wrapping the final science investigations on the slopes of Cape Tribulation, Opportunity climbed up and over the rim of Endeavour Crater in March and embarked on the journey south toward its next science target: Perseverance Valley.
Field Report from Mars: Sol 4669
Opportunity has begun driving down a long southward slope in Endeavour, heading toward Perseverance Valley.
