Solar Cells are Far Out!

         The Stardust spacecraft passed through aphelion, its furthest point from the Sun, 2.72 AU and is now on its way toward the inner solar system.
         This is the farthest distance ever reached by a solar-powered spacecraft. Far beyond the orbit of Mars, the sunlight intensity is only 13% of what we see at Earth, resulting in very cold temperatures and diminishing the power the spacecraft's solar cells can generate. However, the battery's charge state has not dropped below 91.6 %.
         The spacecraft has now successfully traveled 1.5 of its planned 3 loops around the sun.
         Gosh! They can do so much with solar power now. Hey guys, how about a car that run on sunpower? How about a hot-shot solar battery for my computer!
