Journal mt1955's Journal: Rover Solar Panels Cleaned
The rovers landed on Mars in January with solar cells capable of providing more than 900 watt-hours of electricity per day. Spirit's output has dropped to about 400 watt-hours, partly because Martian dust has caked its solar panels. Opportunity's output also declined at first - to around 500 watt-hours - but over the past six months it has regained power (New Scientist, 30 October, p 6). Lately, its solar cells have been delivering just over 900 watt-hours.
Rover team leader Jim Erickson at NASA's Jet Propulsion Laboratory in Pasadena, California, told New Scientist that a process still not understood.
