The craft may be able to hibernate through a dust storm that could last months

The veteran Opportunity rover isn’t dead yet. Currently, the craft is in a deep sleep to ride out a massive Martian dust storm, NASA officials said in a briefing on June 13. The rover may wake itself up when the storm ends.
Opportunity is enveloped in a vast dust storm that grew from a small patch spotted on May 30 to cover a quarter of the planet by June 12 (SN Online: 6/11/18). Too little sunlight is reaching the rover’s solar panels, so Opportunity is in low-power mode — just barely enough to run the rover’s internal clock — until its batteries can charge again. The team hasn’t heard from Opportunity since June 10, and no transmissions are expected until the storm clears.
The Martian summer is just beginning, so the rover should stay warm enough to survive for a long time in this mode, said
