Opportunity rover at Perseverance Valley – Farewell view  Featured on Astronomy Picture of the Day (APOD) on Feb. 15, 2019. This pre-dust storm panoramic mosaic view was one of the last ones taken by NASA’s Opportunity rover and shows the spectacular view from her approximate current position as of June 2018 after traveling halfway down the fluid carved slope of Perseverance Valley – while peering into the interior of vast Endeavour Crater.  This navcam camera photo mosaic was assembled by Ken Kremer and Marco Di Lorenzo from raw images taken on Sol 5074  (3 May 2018) and colorized.

CAPE CANAVERAL,
FL – ‘Opportunity
at Perseverance Valley’ is the featured image on today’s Astronomy Picture of the Day (APOD) Feb15, 2019 – the mosaic was created by the imaging team of Ken Kremer and Marco
Di Lorenzo.


NASA declared the Opportunity mission complete on Feb. 13 after no transmissions were received in a final try following 8 months
of dogged attempts to recontact the six wheeled robot after a historic planet
encircling dust storm hit Mars and knocked out all  communications – ceasing
on June 10, 2018. 


‘Opportunity at Perseverance Valley’ is a farewell view across the Martian Landscape peering
around vast Endeavour Crater – As seen through the eyes of NASA’s Opportunity MarsExploration Rover (MER) mission after 15 Years Roving the Red Planet!


‘Perseverance Valley’ is the
location where she stands for eternity. Although designed and ‘wannentied’ as a
mere 90 day mission, she actually endured and explored for over 5000 sols. That’s
more than 55 times beyond
the design lifetime of what the scientists and engineers planned. 


Here is the text from today’s APOD:


Explanation: Opportunity had already reached Perseverance Valley by June of 2018. Its
view is reconstructed in a colorized mosaic of images taken by the Mars
Exploration Rover’s Navcam. In fact, Perseverance Valley is an
appropriate name for the destination. Designed for a 90 day
mission, Opportunity had traveled across Mars for over 5,000 sols (martian
solar days) following a January 2004 landing
in Eagle crater. Covering a total distance of over 45 kilometers (28 miles),
its intrepid journey of exploration across the Martian landscape has come to a
close here. On June 10, 2018, the last transmission from the solar-powered
rover was received as a dust storm engulfed
the Red Planet. Though the storm has subsided, eight months of
attempts to contact Opportunity have not been successful and its trailblazing
mission ended after almost 15 years of exploring the surface of Mars.

When the massive planet-encircling dust storm hit Opportunity had
been descending down and exploring Perseverance
Valley located along the eroded western rim of the gigantic 22-km diameter (14
mi) impact crater named Endeavour.

NASA’s Opportunity rover acquired this Martian panoramic view from a promontory that overlooks Perseverance Valley below – scanning from north to south. It is centered on due East and into the interior of Endeavour crater. Perseverance Valley descends from the right and 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. Rover deck and wheel tracks at right.

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. Rover mast shadow at center and deck at left. This navcam camera photo mosaic was assembled by Ken Kremer and Marco Di Lorenzo from raw images taken on Sol 4780 (5 July 2017) and colorized.

As of Feb 13, 2019, the
day the mission was declared complete, long lived Opportunity had survived or
experienced over 5350 Sols (or Martian days) roving the harsh environment of
the Red Planet. 


Opportunity has taken over
228,771 images and traversed over 28.06 miles (45.16 kilometers) – more than a marathon. 


Watch for Ken’s continuing onsite coverage of NASA, SpaceX, ULA,
Boeing, Lockheed Martin, Orbital ATK and more space and mission reports direct
from the Kennedy Space Center, Cape Canaveral Air Force Station, Florida and
Wallops Flight Facility, Virginia.

15 Year Traverse Map for NASA’s Opportunity rover from 2004 to 2019. This map shows the entire 45-kilometer (28 mi) path the rover has driven on the Red Planet during over 15 Earth years (7.8 Mars years) and more than a marathon runners distance for over 5300 Sols, or Martian days, since landing inside Eagle Crater on Jan 24, 2004 – to current and final 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. Credit: NASA/JPL/Cornell/ASU/Marco Di Lorenzo/Ken Kremer/kenkremer.com
