This is NASA’s Jupiter probe“Juno”Visible light camera is installed in“JunoCam”Taken usingJupiter’s moon Europahe is. The colors in the image have been amplified to make terrain features more visible. Its appearance, with countless threads running across its surface, gives a very different impression of Earth’s moon covered in craters.
This image is submitted by JunoJupiter’s forty-fifth flight(close paragraph)「PJ45」It was taken on September 29, 2022, when at this time Juno is observing not only Jupiter, but also Europa. According to NASA, JunoThe closest altitude in Europe is 352 kmKent. This is the third time in history that a spacecraft at an altitude of less than 500 km has passed over Europe and the Jupiter probe“Galileo”He crossed 351 kilometers on January 3, 2000.First flight in 22 yearshad become.
Juno vs Europa23.6 km/sSince it was flying at a relative speed of about 85,000 km/h, it was only possible to collect data for two hours. The time was limited, but JunoHigh-resolution imaging of Europa’s surface(1 km per pixel) and cover the surfaceice crust structureFrom Europeinternal、Surface composition、ionosphere、Interaction with Jupiter’s magnetosphereWe were also able to collect valuable data about the Southwest Research Institute (SwRI), the principal investigator in JuneauScott Bolton“The process has begun[تحليل البيانات]just yet ,Juno’s Europa Air Program has been a huge successcommented.
Europa’s icy crust filled with liquid waterinland seaIt is believed that it exists, and from the surfacethe heaterIt has been pointed out that water may be vented as such, and surface material may be carried into the inland sea. The science team compared the Europa images obtained by Juno with those obtained on previous missions.How have surface features changed over the past 20 yearswill be checked.
In addition, based on information about the structure of subsurface ice obtained from images and microwave radiometer (MWR) data,Reservoir exploration is expected to be relatively shallow from the surfaceIt is expected that new knowledge will be obtained, such as data that will be useful to himThe data collected by Juno will be used by NASA’s unmanned spacecraft, which is scheduled to launch in 2024 and reach Jupiter in 2030.Europa ClipperIt is also useful for exploring Europa by
