From Devin Coldewey, TechCrunch:

Opportunity, one of two rovers sent to Mars in 2004, is officially offline for good, NASA  and JPL officials announced today at a special press conference. “I declare the Opportunity mission as complete, and with it the Mars Exploration Rover mission as complete,” said NASA’s Thomas Zurbuchen.

The cause of Opportunity’s demise was a planet-scale sandstorm that obscured its solar panels too completely, and for too long, for its onboard power supply to survive and keep even its most elementary components running. It last communicated on June 10, 2018, but could easily have lasted a few months more as its batteries ran down — a sad picture to be sure. Even a rover designed for the harsh Martian climate can’t handle being trapped under a cake of dust at -100 degrees Celsius for long

From Cal Jeffrey, TechSpot:

It appears that NASA’s Mars rover Opportunity is dead. Mars scientist Dr. Tanya Harrison tweeted that the last commands sent to the rover were met with silence. NASA will be holding a press conference (below) at 2 pm EST to discuss what this means and answer questions.…

From Marina Koren, The Atlantic:

The Mars probe came barreling in. It streaked through the planet’s atmosphere at about 12,000 miles per hour. With the surface in sight, its parachute unfurled. The probe fired its rockets to slow itself down, and inflated its airbags to cushion the landing. Touching down gently, it bounced across the clay-colored terrain.…

…As engineers prepared to transmit their final commands, through massive radio antennae positioned around the world, the mood at JPL was somber, according to Tanya Harrison, a scientist on the mission.

“The rover surpassed every single expectation we could’ve possibly had,” Harrison says. “But I’m not sure anything can fully prepare you for the wave of emotion of hearing a mission you work on is coming to an end.”

From Adam Gabbatt and Nicola Davis, The Guardian:

Nasa declared the 15-year mission of the veteran Mars rover Opportunity finally over on Wednesday, crediting the robot as having “transformed our understanding of our planet”.

The golf buggy-sized vehicle last made contact with Earth eight months ago, after being caught in a global dust storm.…

…The final attempt at communication with Opportunity on Tuesday night was, it seems, an emotional affair. Dr Tanya Harrison, a planetary scientist who worked on the mission, tweeted: “There were tears. There were hugs. There were memories and laughs shared.
