Tech NASA's $1 billion Jupiter probe just sent back dazzling new photos of the giant planet and its Great Red Spot

  • Published:

NASA's Juno spacecraft flew by Jupiter for the 12th time on April 1. The robot took unbelievable new images of the solar system's largest planet and storm.

Once every 53.5 days, NASA's Juno probe screams over Jupiter's cloud tops roughly 75 times as fast as a bullet.

The spacecraft has used these high-speed flybys, called perijoves, to document the gas giant like never before since August 2016. It records the planet with radar systems, radiation detectors, magnetic and gravitational field recorders, and more.

But NASA's beautiful new images of Jupiter come from an optical camera called JunoCam. After each perijove, the space agency uploads the raw photo data to its websites.

Juno finished its 12th perijove on April 1. Since then, people around the world have downloaded JunoCam's raw black-and-white data, processed it into stunning color pictures, and shared the files for all to see.

"Jupiter is in constant flux so it's always a surprise to see what is going on in those cloudscapes," Seán Doran, a graphic artist and a prolific processor of JunoCam images, told Business Insider in an email. He added that it can take hours to complete a single image.

Here are some of the most dazzling portraits of Jupiter — and its shrinking Great Red Spot super-storm — that Doran and others have created in the past week.

Juno makes a highly elliptical orbit over Jupiter's poles. It's a compromise between getting unprecedented new data and staying out of the planet's intense radiation fields.

Juno passes within a few thousand miles of Jupiter's cloud tops at each perijove's closest approach. During this maneuver, the probe reaches a speed of about 130,000 mph.

JunoCam takes several images of the regions it passes during each perijove. Doran and his collaborator Gerald Eichstädt recently figured out how to turn those series of photos into animations that show swirling, brewing storms over time.



They're learning other new tricks, too, and using them on older JunoCam data. This image shows how several different photos of the Great Red Spot in July 2017 were stitched together.

Doran said such composite images "afford us a wider and more complete view of certain regions on Jupiter than is possible with just one image."

Juno's primary mission is slated to end after its 14th perijove, on July 16, 2018. However, NASA may extend the mission by two or three years, pending a review.

A representative for the Juno mission at NASA did not respond to Business Insider's questions about the plan for the probe after its last scheduled perijove.



However, NASA will ultimately destroy Juno by plunging into the clouds of Jupiter. The reason? The space agency doesn't want the probe to crash into the planet's icy moon Europa.

NASA doesn't want to contaminate those oceans with bacteria from Earth that's stuck to Juno. In the future, though, it could send a super-sterile mission beneath the ice to search for aliens.
