Farewell, Oppy

The Washington Post: Opportunity, NASA’s record-setting Mars rover, is declared dead after 15 years. “A eulogy for the spacecraft that transformed our understanding of the Red Planet.” By Sarah Kaplan.

Opportunity’s historic mission, which uncovered signs of Mars’s watery past and transformed our understanding of the Red Planet, has finally come to an end after 15 years, NASA declared Wednesday.

The cause was system failure precipitated by power loss during a catastrophic, planetwide dust storm that engulfed the Mars rover last summer.

“It’s going to be very sad to say goodbye,” said John Callas, the mission’s project manager. “But at the same time, we’ve got to remember this has been 15 years of incredible adventure.”

Opportunity’s mission was planned to last just 90 days, but it worked for 5,000 Martian “sols” (which are about 39 minutes longer than an Earth day) and traversed more than 28 treacherous miles — two records for NASA.”
