spacecraft flying close JupiterThe largest moon of the other moons in more than two decades Revealing the amazing ice crystal ball.
The first two images from NASA On June 7, 2021, Juno’s flyby of Jupiter’s giant moon Ganymede has been received on Earth. This image is from the Jupiter probe’s JunoCam imager. And another image from the Stellar Reference Unit star telescope shows surfaces in amazing detail. including craters Clearly dark and light landscapes and longitudinal features that may be linked to tectonic faults.
“This is the closest spacecraft to any spacecraft. come to this gigantic moon in a generation,” said Juno Principal Investigator Scott Bolton of the Southwest Research Institute in San Antonio. “We will take our time before drawing any scientific conclusions. but even so We can marvel at this celestial miracle.”
The spacecraft’s JunoCam Visible Light Imager used a green filter to capture nearly all sides of the icy moon. Photographic professionals will be able to give Ganymede a color portrait. Image resolution is approximately 0.6 miles (1 kilometer) per pixel.
In addition, Juno’s star reference unit, a guiding camera that keeps the spacecraft on track. gave a black and white picture of Ganymede’s dark side (Opposite the Sun) bathed in the dim light scattered by Jupiter. Image resolution is between 0.37 and 0.56 miles (600 to 900 meters) per pixel.
“The conditions in which we gathered Ganymede’s dark side images are ideal for low-light cameras such as the Stellar Reference Unit,” said Heidi Becker, head of the radiation monitoring unit at Juno. JPL“This is a different part of the surface than what JunoCam sees in direct sunlight. It will be fun to see what the two teams can combine.”
The spacecraft will send more images of the Ganymede flyby in the coming days. The raw image of JunoCam is available here.
The solar-powered spacecraft’s encounter with the Jovian moon is expected to provide insights into its composition. ionosphere magnetosphere and ice crust At the same time it provides measurements of the radiation environment that will benefit future missions to the Jovian system.
