Outstanding Opportunity Rover Making ‘Amazing New Discoveries’ 13 Years After Mars Touchdown
13 Years on Mars!

NASA’s truly outstanding Opportunity rover continues “making new discoveries about ancient Mars” as she commemorates 13 Years since bouncing to a touchdown on Mars, in a feat that is “truly amazing” – the deputy chief scientist Ray Arvidson told Universe Today exclusively.
Resilient Opportunity celebrated her 13th birthday on Sol 4623 on January 24, 2017 PST while driving south along the eroded rim of humongous Endeavour crater – and having netted an unfathomable record for longevity and ground breaking scientific discoveries about the watery environment of the ancient Red Planet.
“Reaching the 13th year anniversary with a functioning rover making new discoveries about ancient Mars on a continuing basis is truly amazing,” Ray Arvidson, Opportunity Deputy Principal Investigator of Washington University in St. Louis, told Universe Today.
Put another way Opportunity is 13 YEARS into her 3 MONTH mission! And still going strong!
Indeed she is 51 times beyond her “warrantied” life expectancy of merely 90 Sols promised at the time of landing so long ago – roving the surface of the 4th rock from the Sun during her latest extended mission; #10.
How was this incredible accomplishment achieved?
“Simply a well-made and thoroughly tested American vehicle,” Arvidson responded.

The six wheeled rover landed on Mars on January 24, 2004 PST on the alien Martian plains at Meridiani Planum -as the second half of a sister act.
Her twin sister Spirit, had successfully touched down 3 weeks earlier on January 3, 2004 inside Gusev crater and survived more than six years.

Opportunity concluded 2016 and starts 2017 marching relentlessly towards an ancient water carved gully along the eroded rim of vast Endeavour crater – the next science target on her heroic journey traversing across never before seen Red Planet terrains.
Huge Endeavour crater spans some 22 kilometers (14 miles) in diameter.
Throughout 2016 Opportunity was investigating the ancient, weathered slopes around the Marathon Valley location in Endeavour crater. The area became a top priority science destination after the slopes were found to hold a motherlode of ‘smectite’ clay minerals based on data from the CRISM spectrometer circling orbiting aboard a NASA Mars orbiter.
The smectites were discovered via extensive, specially targeted Mars orbital measurements gathered by the CRISM (Compact Reconnaissance Imaging Spectrometer for Mars) spectrometer on NASA’s Mars Reconnaissance Orbiter (MRO) – accomplished earlier at the direction of Arvidson.
Opportunity has been exploring Endeavour since arriving at the humongous crater in 2011. Endeavour crater was formed when it was carved out of the Red Planet by a huge meteor impact billions of years ago.
“Endeavour crater dates from the earliest Martian geologic history, a time when water was abundant and erosion was relatively rapid and somewhat Earth-like,” explains Larry Crumpler, a science team member from the New Mexico Museum of Natural History & Science.
As of today, Jan 31, 2017, long lived Opportunity has survived 4630 Sols (or Martian days) roving the harsh environment of the Red Planet.
Opportunity has taken over 216,700 images and traversed over 27.12 miles (43.65 kilometers) – more than a marathon.

See our updated route map below.
The rover surpassed the 27 mile mark milestone early last month on November 6 (Sol 4546).
The power output from solar array energy production is currently 414 watt-hours, before heading into another southern hemisphere Martian winter in 2017.
Meanwhile Opportunity’s younger sister rover Curiosity traverses and drills into the lower sedimentary layers at the base of Mount Sharp.

13 Year Traverse Map for NASA’s Opportunity rover from 2004 to 2017. This map shows the entire 43 kilometer (27 mi) path the rover has driven on the Red Planet during more than 13 years and more than a marathon runners distance for over 4614 Sols, or Martian days, since landing inside Eagle Crater on Jan 24, 2004 – to current location at the western rim of Endeavour Crater. After descending down Marathon Valley and after studying Spirit Mound, the rover is now ascending back uphill on the way to a Martian water carved gully.
