The First Solar Powered Space Craft Juno Heads To Jupiter
A Solar Powered Space Craft Heads To Jupiter
Juno is the first solar powered spacecraft and it is designed to operate at Jupiter’s distance from the sun. At Jupiter, Juno receives 25x less sunlight than it would at Earth. Its three large solar array wings, with more than 18,000 individual solar cells, produce about 500 watts at Jupiter, enough to power its heaters, computers and instruments.
After 5 years in space, Juno is expected to arrive into Jupiter’s orbit July 4, 2016. The distance to the planet varies but on average the photographs will take 43 minutes to reach earth. I cannot wait.
