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
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!
