Ride in addition to Juno
The Juno spacecraft made its most recent flyby of the huge world Jupiter on June 8, 2021. Shortly before its closest point to Jupiter– the 34th of the mission, or perijove 34– Juno flew closer to Jupiters big moon Ganymede than any spacecraft has in more than two decades. It lets you ride along with the Juno spacecraft on this most current sweep past Ganymede and Jupiter.
The animation shows just how gorgeous deep area expedition can be. Its a method for people to think of exploring our planetary system direct by seeing what it would resemble to be orbiting Jupiter and flying previous among its icy moons.
The images to make this time-lapse animation originated from JunoCam, the visible-light camera/telescope aboard the Juno spacecraft. NASA described:
The 3:30- minute-long animation begins with Juno approaching Ganymede. It passed within 645 miles (1,038 km) of Ganymedes surface area at a relative velocity of 41,600 mph (67,000 kph). The images shows several of the moons light and dark areas. Darker areas are thought to arise from ice sublimating into the surrounding vacuum, leaving behind darkened residue. The imagery likewise reveals the crater Tros, which is among the largest and brightest crater scars on Ganymede.
It takes just 14 hours, 50 minutes for Juno to take a trip the 735,000 miles (1.18 million km) in between Ganymede and Jupiter. The viewer is carried to within just 2,100 miles (3,400 km) above Jupiters spectacular cloud tops. By that point, Jupiters powerful gravity has sped up the spacecraft to nearly 130,000 miles per hour (210,000 kph) relative to the planet.
Among the Jovian climatic functions that can be seen are the circumpolar cyclones at the north pole and 5 of the gas giants string of pearls. These are 8 huge storms rotating counterclockwise in Jupiters southern hemisphere. They appear as white ovals.
Utilizing info that Juno has actually learned from studying Jupiters environment, the animation group simulated lightning one might see as we pass over Jupiters huge thunderstorms.

It takes just 14 hours, 50 minutes for Juno to travel the 735,000 miles (1.18 million km) between Ganymede and Jupiter. Juno follows an extremely elliptical, polar orbit around Jupiter, created to reduce its direct exposure to Jupiters radiation belts.

How they made the video
Resident researcher Gerald Eichstädt used composite images of Ganymede and Jupiter to offer us the electronic cameras viewpoint. For both Ganymede and Jupiter, NASA stated:
JunoCam images were orthographically predicted onto a digital sphere and used to create the flyby animation. Artificial frames were included to provide views of technique and departure for both Ganymede and Jupiter.
Juno objective reached 2025
NASA said that, as planned, Jupiters gravitational pull has actually now impacted Junos orbit. Now Jupiters strong gravity has actually decreased Junos orbit to 43 days.
The Juno mission was originally set up to end in July 2021. Juno will now continue checking out Jupiter through September 2025, or up until the spacecrafts end of life.
This growth jobs Juno with becoming an explorer of the complete Jovian system– Jupiter and its rings and moons– with several rendezvous prepared for 3 of Jupiters the majority of interesting Galilean moons: Ganymede, Europa, and Io.
The next Juno flyby of Jupiter, the 35th of the objective, is set up for a few days from now, July 21, 2021.
Juno follows a highly elliptical, polar orbit around Jupiter, developed to minimize its exposure to Jupiters radiation belts. Each orbit is slightly adjusted so the craft will fly over a different face of Jupiter when closest. Hence Juno has studied Jupiters entire surface over its 37 prepared orbits in between 2016 and July 2021.
Bottom line: A gorgeous video revealing the most recent flyby of the Juno spacecraft at Jupiter. In the course of this flyby, Juno came closer to Jupiters large moon Ganymede than any spacecraft has in two decades.
