Ganymede flyby. Credit score: NASA
The probe flew nearer to Jupiter’s largest moon, Ganymede, than every other spacecraft in additional than 20 years, providing dramatic glimpses of each the icy orb and the gasoline large.
On June 7, 2021, NASA’s Juno spacecraft flew nearer to Jupiter’s ice-encrusted moon Ganymede than any spacecraft in greater than 20 years. Lower than a day later, Juno made its thirty fourth flyby of Jupiter, racing over its roiling environment from pole to pole in lower than three hours. Utilizing the spacecraft’s JunoCam imager, the mission group has put collectively this animation to supply a “starship captain” standpoint of every flyby.
“The animation exhibits simply how lovely deep house exploration might be,” mentioned Scott Bolton, principal investigator for Juno from the Southwest Analysis Institute in San Antonio. “The animation is a method for individuals to think about exploring our photo voltaic system firsthand by seeing what it will be prefer to be orbiting Jupiter and flying previous one among its icy moons. In the present day, as we method the thrilling prospect of people with the ability to go to house in orbit round Earth, this propels our creativeness a long time into the longer term, when people will likely be visiting the alien worlds in our photo voltaic system.”

For each worlds, JunoCam photos have been orthographically projected onto a digital sphere and used to create the flyby animation. Artificial frames have been added to supply views of method and departure for each Ganymede and Jupiter. Credit score: NASA/JPL-Caltech/SwRI/MSSS
The three:30-minute-long animation begins with Juno approaching Ganymede, passing inside 645 miles (1,038 kilometers) of the floor at a relative velocity of 41,600 mph (67,000 kph). The imagery exhibits a number of of the moon’s darkish and lightweight areas (darker areas are believed to outcome from ice sublimating into the encircling vacuum, abandoning darkened residue) in addition to the crater Tros, which is among the many largest and brightest crater scars on Ganymede.
It takes simply 14 hours, 50 minutes for Juno to journey the 735,000 miles (1.18 million kilometers) between Ganymede and Jupiter, and the viewer is transported to inside simply 2,100 miles (3,400 kilometers) above Jupiter’s spectacular cloud tops. By that time, Jupiter’s highly effective gravity has accelerated the spacecraft to nearly 130,000 mph (210,000 kph) relative to the planet.
Among the many Jovian atmospheric options that may be seen are the circumpolar cyclones on the north pole and 5 of the gasoline large’s “string of pearls” – eight huge storms rotating counterclockwise within the southern hemisphere that seem as white ovals. Utilizing data that Juno has discovered from finding out Jupiter’s environment, the animation group simulated lightning one would possibly see as we cross over Jupiter’s large thunderstorms.
The digital camera’s standpoint for this time-lapse animation was generated by citizen scientist Gerald Eichstädt, utilizing composite photos of Ganymede and Jupiter. For each worlds, JunoCam photos have been orthographically projected onto a digital sphere and used to create the flyby animation. Artificial frames have been added to supply views of method and departure for each Ganymede and Jupiter.
As deliberate, the gravitational pull of the enormous moon has affected Juno’s orbit, ensuing within the discount of its orbital interval from 53 days to 43 days. The following flyby of Jupiter, the thirty fifth of the mission, is scheduled for July 21.
Extra Concerning the Mission
JPL, a division of Caltech in Pasadena, California, manages the Juno mission for the principal investigator, Scott J. Bolton, of the Southwest Analysis Institute in San Antonio. Juno is a part of NASA’s New Frontiers Program, which is managed at NASA’s Marshall House Flight Middle in Huntsville, Alabama, for the company’s Science Mission Directorate in Washington. Lockheed Martin House in Denver constructed and operates the spacecraft.
