"Opportunity rover faces challenges on Mars"
- The rover needed at least 400 watt-hours of power per day to avoid hibernation due to Martian winter and dust on solar panels.
- Cleaning events, triggered by wind, helped remove dust from the panels, boosting energy production.
- Dust storms on Mars caused dust to settle on the rover, impacting its operations.
- Opportunity encountered a rock, Pinnacle Island, which seemed to appear mysteriously, sparking various theories.
- The rock was later discovered to be a result of Opportunity cracking a rock in half.
- The rover faced issues with its onboard computer randomly resetting, leading to missed science activities.
- A decision was made to reformat the drive to address the computer issues.
- Comet Siding Spring passed by Mars, impacting the planet's weak magnetic field temporarily.
- Opportunity reached Marathon Valley, where it faced challenges due to flash memory issues.
