NASA’s Juno Mission Delivers Initial Science Results

NASA’s Juno objective is rewording exactly what planetary researchers believed they learnt about Jupiter, the biggest and most massive world in our Planetary system: the most current science arises from the mission depict the gas giant as a complex, rough world, with enormous polar cyclones, plunging storm systems, and a very strong magnetic field that might suggest it was produced closer to the planet’s surface area than formerly thought.

Lasting a few hours, the solar-powered spacecraft flies from the north pole to the south pole, dipping within 2,600 miles (4,200 km )of the equatorial clouds and underneath Jupiter’s most intense and damaging radiation belts.The findings from the very first data-collection pass are being released this week in 2 papers in the journal Science, as well as 44 documents in the journal Geophysical Research study Letters.

“We knew, going in, that Jupiter would throw us some curves,” stated Juno primary investigator Dr. Scott Bolton, from the Southwest Research Institute.

“But now that we are here we are discovering that Jupiter can toss the heat, along with knuckleballs and sliders. There is a lot going on here that we didn’t expect that we have actually needed to take an action back and begin to reconsider of this as an entire new Jupiter.”

“Exactly what we’ve found out so far is earth-shattering. Or should I state, Jupiter-shattering,” he added.

This series of JunoCam images reveals how quickly the viewing geometry modifications for NASA’s Juno spacecraft as it swoops by Jupiter. As soon as every 53 days Juno swings near to Jupiter, speeding over its clouds. In just 2 hours, the spacecraft takes a trip from a perch over Jupiter’s north pole through its closest approach (perijove), then passes over the south pole on its method back out. This series reveals 14 enhanced-color images. The very first image on the left reveals the whole half-lit globe of Jupiter, with the north pole approximately in the center. As the spacecraft gets closer to Jupiter, the horizon relocates and the series of visible latitudes shrinks.

The 3rd and fourth images in this series show the north polar area turning far from our view while a band of wavy clouds at northern mid-latitudes comes into view. By the 5th image of the sequence the band of rough clouds is well focused in the image. The seventh and eighth images were taken right before the spacecraft was at its closest indicate Jupiter, near Jupiter’s equator. Although these two pictures were taken simply four minutes apart, the view is altering quickly. As the spacecraft crossed into the southern hemisphere, the brilliant ‘south tropical zone ‘controls the ninth, 10th and 11th images.
