NASA: The first close-up photos of the satellite of Zeus Ganymede

Near Ganymede, its largest satellite For and our entire solar system, passed the US space agency (NASA) Juno spacecraft, and sent to Earth the first close-ups of the distant frozen moon-mammoth in two decades.

The ship approached at a distance of about 1,000 kilometers above Ganymede, which with a diameter of 5,260 kilometers is larger than the planet Mercury. THE NASA had previously studied Ganymede first with the Voyager missions in the late 1970s and then with the Galileo in 2000.

According to AMPE, the approach of a new vessel allowed the collection of new valuable scientific data, such as measurements of the magnetic field of Ganymede (the only satellite in the solar system that is large enough to generate its own magnetosphere), as well as its cortex. . The photo was taken with the boat’s high-resolution JunoCam camera. So far, two new black-and-white photographs have reached NASA, revealing in detail craters and possible tectonic faults.

Launched a decade ago and orbiting Jupiter since July 2016, Juno will continue to study the giant planet and its turbulent atmosphere until 2025 and will pass by other large moons, such as Europe in 2022 and Ios in 2023. Jupiter has 79 known satellites and Ganymede was first discovered by Galileo in 1610, along with three other large moons of Jupiter.

Next year the European Space Agency (ESA) will launch the JUICE (Jupiter Icy Moons Explorer) mission which will make successive approaches to three large moons of Jupiter (Ganymede, Europe, Kallisto), before orbiting Ganymede in 2032. In the meantime, in the current decade, NASA will have launched the new Europa Clipper mission to the satellite Europe, which has a huge underground ocean , with a possible presence of life.
