Following two flybys of Jupiter’s innermost Galilean moon Io, teams using data from NASA’s Juno… The post Juno reveals surprising subsurface tempertures at Io, remarkably smooth surface appeared first on NASASpaceFlight.com.
Description This graphic illustrates the areas of Jupiter’s moon Io sampled by the Microwave Radiometer (MWR) instrument aboard NASA’s Juno spacecraft during two close flybys. The black overlapping lines show the instrument’s footprints during Perijove 57 on Dec. 30, 2023, when the spacecraft primarily mapped the northern hemisphere. The blue lines represent Perijove 58 on […]
Description This map represents data captured by the Microwave Radiometer (MWR) aboard NASA’s Juno spacecraft, indicating heat rising from just beneath the surface of Jupiter’s moon Io. While infrared instruments measure the temperature of the moon’s surface, the lowest frequency microwave channels (0.6 and 1.25 gigahertz) on the MWR can penetrate between about 6 and […]
NASA’s Juno mission has provided the first measurements of the temperature below the surface of Jupiter’s moon Io, revealing significant heating within the shallow subsurface of the most volcanically active world in the solar system. Collected during two close flybys, the data also shows that most of Io’s surface is remarkably smooth and composed of […]
