NASA's Juno will come within 645 miles (1,038 km) of Jupiter's largest moon Ganymede and collect important observations. On Monday, June 7 at 1:35pm EDT (11:05pm IST), the flyby will be the closest spacecraft to the Solar System's largest natural satellite since NASA's Galileo in May 2000. In addition to the striking imagery, the spacecraft will also gather insights into Ganymede's structure, ionosphere, magnetosphere and ice shell, NASA said. The Galileo spacecraft passed as low as 162 miles (261 km) above the surfaces of the Galilean moons, producing detailed images.

Juno will begin collecting data at least three hours before reaching the closest point expected to reach the solar system's largest satellite, the space agency said. between devices, NASA In addition to the Ultraviolet Spectrograph (UVS) and the Jovian Infrared Auroral Mapper (JIRAM), Juno's Microwave Radiometer (MWR) will observe Ganymede's water-ice layer and collect data on its composition and temperature, said Dr.

a report good The spacecraft has a suite of sensitive instruments capable of viewing Ganymede in ways that were never possible before, said Scott Bolton, Juno's principal investigator at the NASA Jet Propulsion Laboratory (JPL). "By flying so closely, we will be bringing Ganymede exploration into the 21st century, complementing both future missions with our unique sensors and the next generation of missions from the Jovian system - NASA's Europa Clipper and ESA's (European Space Agency). Will help prepare for the Jupiter ICE Moons Explorer (JUICE) mission,” he said.

Bolton said Jupiter's largest moon has some light and dark regions that indicate that some regions may be pure ice, while others may also contain silty ice. He said the MWR instrument will provide the first in-depth investigation of how ice composition and composition changes with depth, helping us to better understand how the ice shell forms and the ongoing processes that change over time. Along with rejuvenating the snow.

The JPL report said Ganymede is larger than Mercury and the only moon in the Solar System to have its own magnetosphere – a bubble-shaped region of charged particles around the celestial body.

According to Space.comSeveral spacecraft in the past, including Pioneer 10 in 1973, Pioneer 11, Voyager 1 and Voyager 2 in 1974, have flown from Ganymede and returned striking photos during their flybys. The Galileo spacecraft passed as little as 162 miles (261 km) over the surfaces of the Galilean moons and produced detailed images.

According to NASA information Juno Overview Page, Juno's main goal is to understand the origin and evolution of Jupiter.

Under its dense cloud cover, Jupiter holds the secrets of the fundamental processes and conditions that governed the solar system during its formation, the space agency says. The planet may also provide important knowledge for understanding planetary systems being discovered around other stars.
