NASA Juno flies close to Ganymede, returning ultra-clear photos of 20 years-ezone.hk-Technology Focus-Digital

The space vehicle Juno launched by NASA entered Jupiter’s polar orbit. Recently, “Juneo” flew over Ganymede, the largest moon of Jupiter and took photos, returning the first batch of ultra-clear close-up photos in nearly 20 years.

  • NASA launches the spacecraft Juno into Jupiter’s polar orbit
  • Juno recently successfully overflew the largest satellite “Ganymede” at an altitude of only 1,038 kilometers.
  • Send back the first ultra-clear close-up photos in 20 years

Ganymede is the largest moon in the solar system. It is mainly composed of silicate rocks and icy bodies. It may have an iron-rich liquid core inside. Scientists have even speculated that there may be an iron-rich liquid core 200 kilometers below the surface of Ganymede. A saltwater ocean between two layers of ice. Recently, NASA confirmed that Juno successfully flew close to Europa at a close range of less than 1,038 kilometers, and published two ultra-clear black and white photos returned, one of which shows the size of Europa’s surface. Different craters can clearly distinguish dark and bright topography, or features related to fault structures; the other can be seen on the back of Ganymede’s back to the sun.

Scott Bolton, the chief scientist of the Juno, said that this is the first time in the entire century that a spacecraft has approached this huge satellite and admired the spectacle. Rather, the measured data will help to gain insight into Ganymede’s structure, ionosphere, magnetosphere, ice crust, and radiation environment, which will help future missions.
