Imagery from the solar-powered spacecraft shows some intriguing features on the ice-encased Jovian moon.
Jupiter ’s moon Europa was captured by the Juno Cam instrument aboard NASA’s Juno spacecraft during the mission’s close flyby on Sept. 29, 2022. The images show the fractures, ridges, and bands that crisscross the moon’s surface.
A giant ocean is thought to reside below Europa’s icy exterior, and these surface features have been associated with ““True polar wander occurs if Europa’s icy shell is decoupled from its rocky interior, resulting in high stress levels on the shell, which lead to predictable fracture patterns,” said Candy Hansen, a Juno co-investigator who leads planning for JunoCam at the Planetary Science Institute in Tucson, Arizona.
This innovative approach to imaging allowed complex surface features to stand out, revealing intricate networks of cross-cutting ridges and dark stains from potential plumes of water vapor. One intriguing feature, which covers an area 23 miles by 42 miles , was nicknamed by the team “the Platypus” because of its shape.
