Journey to Jupiter produces remarkable images

A NASA spacecraft has captured the best views of the planet Jupiter yet. The views revealed turbulent storms in the north pole.
Jupiter's northern polar region is stormier than expected. It appears bluer than the rest of the planet. This is according to mission chief scientist Scott Bolton of the Southwest Research Institute. It is in San Antonio, Texas.
"This image is hardly recognizable as Jupiter," he said in a statement.
On September 2, NASA released a batch of close-up pictures. They were taken by the Juno spacecraft when it recently flew within 2,500 miles of Jupiter's dense cloud tops.
During the rendezvous that took Juno from pole to pole, the solar-powered spacecraft turned on its camera and instruments to collect data.
The first glimpse of Jupiter's poles came in 1974 when Pioneer 11 flew by on its way to Saturn.
The detailed pictures taken by Juno look "like nothing we have seen or imagined before," Bolton said.
Juno also sent back unique views of Jupiter's bright southern lights. They are considered the most powerful in the solar system.
The flyby was the first of three dozen planned close passes during the 20-month mission.
Unlike rocky Earth and Mars, Jupiter is a gas giant. It likely formed before Earth and Mars, shortly after the sun. Studying the largest planet in the solar system may hold clues to understanding how Earth and the rest of the planets formed.
After a five-year journey, Juno slipped into orbit around Jupiter in July. Juno will map the massive planet's poles, atmosphere and interior. It's the first spacecraft to carry a titanium vault. The vault is designed to shield its computer and electronics from intense radiation.
Juno is only the second mission to orbit Jupiter. When it completes its job in 2018, it will deliberately crash into Jupiter's atmosphere and disintegrate. NASA planned the finale so that Juno won't accidentally smack into Jupiter's moons, particularly the icy moon Europa. That is a target of future exploration.
