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.
Team - Months - Variety - Techniques - Rover
The team has been trying to reach it for months, employing a variety of increasingly desperate techniques to get the rover to at least respond; even if its memory had been wiped clean or instruments knocked out, it could be reprogrammed and refreshed to continue service if only they could set up a bit of radio rapport. But every attempt, from ordinary contact methods to “sweep and beep” ploys, was met with silence. The final transmission from mission control was last night.
Spirit and Opportunity, known together as the Mars Exploration Rovers mission, were launched individually in the summer of 2003 and touched down in January of 2004 — 15 years ago! — in different regions of the planet.
