SpaceAholicNice panorama: 'Greeley Panorama' from Opportunity's Fifth Martian Winter
This full-circle scene combines 817 images taken by the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity. It shows the terrain that surrounded the rover while it was stationary for four months of work during its most recent Martian winter.
cspgApparently no funding allowed for the rover past Fiscal Year 2019...
Robert PearlmanIn the administration's FY2019 budget proposal, yes.

As NASA is funded on a year-to-year basis, a zeroed out budget in the out years doesn't necessarily mean it won't be funded going forward. Rather, it will be something that Congress will need to take up in FY20 and each year after (assuming the White House's FY20 proposal doesn't revise that line item first).

SpaceAholicOpportunity could have had an even greater extended lifetime if it had the ability to clean its solar panels of dust, reports Forbes.
Because of the results from Sojourner, we knew that dust would accumulate on the solar panels, but only at the extremely slow rate of ~0.29% per Martian day. Over a 90 day mission, that meant a total reduction in power of 23%. There were a number of options, then, for how to design Spirit and Opportunity...

Instead, we chose the most cost-effective (i.e., cheapest) solution: simply build bigger solar panels. If, over a 90 day mission, we expected up to 23% dimming, then by building solar panels with at least 23% more surface area, we'd ensure we had all the power we need.

ManInSpaceFrom this NASA release:
NASA's Opportunity rover has been silent since June 10, when a planet-encircling dust storm cut off solar power for the nearly-15-year-old rover. Now that scientists think the global dust storm is "decaying" — meaning more dust is falling out of the atmosphere than is being raised back into it — skies might soon clear enough for the solar-powered rover to recharge and attempt to "phone home."
I have read many articles over the years referring to the rovers going into a "hibernation" mode; but until today had no idea of the many potential issues that could arise while resuming full operations.
Robert PearlmanNASA's Opportunity rover mission is at an end after almost 15 years exploring the surface of Mars and helping lay the groundwork for NASA's return to the Red Planet.
The Opportunity rover stopped communicating with Earth when a severe Mars-wide dust storm blanketed its location in June 2018. After more than a thousand commands to restore contact, engineers in the Space Flight Operations Facility at NASA's Jet Propulsion Laboratory (JPL) made their last attempt to revive Opportunity Tuesday, to no avail. The solar-powered rover's final communication was received June 10.

"I cannot think of a more appropriate place for Opportunity to endure on the surface of Mars than one called Perseverance Valley," said Michael Watkins, director of JPL. "The records, discoveries and sheer tenacity of this intrepid little rover is testament to the ingenuity, dedication, and perseverance of the people who built and guided her."

SpaceAngelRest in peace Opportunity and thanks for a decade and a half of your service on Mars.
Fra MauroRest in peace Opportunity. Thank you for all the wonderful photos and science. You are a monument to all the people at NASA and to the spirit of exploration. May you be visited one day by someone from Earth just like Surveyor was visited by Conrad and Bean.
randyMay she rest in peace.
SkyMan1958Thank you for all the memories, Opportunity!!!
