Salts and Organics Observed on Ganymede’s Surface by NASA’s Juno

Throughout the June 2021 flyby, JIRAM lined a slim vary of latitudes (10 levels north to 30 levels north) and a broader vary of longitudes (minus 35 levels east to 40 levels east) within the Jupiter-facing hemisphere.

“We discovered the best abundance of salts and organics at nighttime and vivid terrains at latitudes protected by the magnetic subject,” mentioned Scott Bolton, Juno’s principal investigator from the Southwest Analysis Institute in San Antonio. “This implies we’re seeing the remnants of a deep ocean brine that reached the floor of this frozen world.”

Ganymede shouldn’t be the one Jovian world Juno has flown by. The moon Europa, thought to harbor an ocean beneath its icy crust, additionally got here beneath Juno’s gaze, first in October 2021 after which in September 2022. Now Io is receiving the flyby remedy. The subsequent shut method to that volcano-festooned world is scheduled for Dec. 30, when the spacecraft will come inside 932 miles (1,500 kilometers) of Io’s floor.

Juno is a part of NASA’s New Frontiers Program, which is managed at NASA’s Marshall House Flight Middle in Huntsville, Alabama, for the company’s Science Mission Directorate in Washington.
