In the course of its flight, Juno will analyze the composition and temperature of the ice and study the Ganymede ionosphere.

Next Monday, NASA’s Juno space probe will fly at a distance 1038 km from GanymedeJupiter’s largest natural satellite.

It is the closest approach since another apparatus, Galileo, Volara 808 kilometers from the mentioned moon. However, Juno is equipped with more advanced instruments “capable of seeing Ganymede in ways that weren’t possible before,” says lead researcher on the project, Scott Bolton, who cited Release From the agency, published on Friday.

As part of a media campaign associated with the upcoming plane, NASA has released an animation of Ganymede, showing known geological structures on its surface in color.

Data collection will begin approximately three hours before the nearest approach. In addition to taking pictures, Juno will study several important characteristics.

Thus, to analyze the composition and temperature of the ice covering it – which, according to scientists, hiding Indoors potentially habitable – the probe will use a microwave radiometer (MWR).

“The Ganymede Ice Sheet contains some light and dark areas, indicating that some areas may be pure ice while others contain dirty ice. MWR will provide the first in-depth investigation of How does the composition and structure of ice differ with depth, which will lead to a better understanding of How the ice sheet is formed and the continuous processes that reappear to ice With time”.

The probe will also study the outer layer of the moon’s atmosphere, where gases form ions under solar radiation.

“When Juno passes behind Ganymede, the radio signals will pass through the ionosphere of Ganymede, causing subtle changes in frequency that two antennas at Australia’s Deep Space Network Canberra Complex must pick up. If we can measure this change, we can Understand the relationship between the Ganymede ionosphere, its intrinsic magnetic field and Jupiter’s magnetosphereDustin Buccino, Mission Engineer.
