Success! NASA's Juno mission has completed a close flyby of Jupiter's Great Red Spot.

All of the probe's science instruments were operational, NASA officials said in a statement, as was the craft's JunoCam. Data and photos are now streaming back to Earth. Raw images of the gigantic storm, 1.3 times as wide as Earth, should be posted in the next few days, NASA said.

Juno approached closest to Jupiter's center on July 10 at 9:55 p.m. EDT (0155 on July 11 GMT), at which point the probe was just 2,200 miles (3,500 kilometers) above the planet's visible cloud tops. After 11 minutes and 33 seconds, Juno passed directly above the Great Red Spot at a height of 5,600 miles (9,000 km). This flyby came as part of Juno's sixth science orbit around the planet; the next close flyby will occur Sept. 1. [Amazing Jupiter Photos by Juno

"For generations, people from all over the world and all walks of life have marveled over the Great Red Spot," Scott Bolton, Juno's principal investigator, from the Southwest Research Institute in San Antonio, said in the statement. "Now we are finally going to see what this storm looks like up close and personal." 

Juno launched in 2011 and arrived at Jupiter on July 4, 2016. During a series of long orbits, the spacecraft is diving down to investigate the gas giant planet over 12 flybys. The researchers will combine Juno's observations of the Great Red Spot with data gathered by ground-based telescopes on Earth to discern what's happening deep inside the whirling storm.
