What hides beneath the ice?

NASA's about to launch a huge spacecraft to a world harboring voluminous seas.
Planetary scientists suspect Jupiter's moon Europa contains an ocean at least twice the size of Earth's. The Europa Clipper probe — which is the length of a basketball court and the largest craft the agency has sent on a planetary mission — is slated to blast to this distant realm on Oct. 10. Before the launch, NASA released a new detailed view of the moon's cracked surface, which shows why for decades researchers have been drawn to this tantalizing place.
"It's perhaps one of the best places beyond Earth to look for life in our solar system," Cynthia Phillips, a NASA planetary geologist and project staff scientist for the space agency's Europa Clipper mission, told Mashable.
On Oct. 2, NASA shared the view below, which was taken from data gathered by the Galileo mission in 1998. It shows a close-up of Europa's chaotic landscape, which is evidence that something below the moon's thick icy crust — like an ocean — is stoking lots of change and deformity. Salty water may escape to the surface along fractures, leaving telltale reddish colors on Europa's ground. And irregular chunks of ice have likely been created by relatively recent surface movement.
"This region sports ice rafts that look like those at Earth's poles, where large chunks of ice break away and float freely on the ocean," the agency wrote. "Much of the region bears the reddish/brownish discoloration seen here — the same as seen along many of Europa's fractures. Scientists believe this material may contain clues about the composition of an ocean beneath the icy surface, if it is proven to exist."

Actually, it's very cool!!!!!
The mission, called Europa Clipper, is now targeted to launch to Jupiter's icy moon Europa no earlier than Monday (Oct. 14) atop a SpaceX Falcon Heavy rocket from Pad 39A of NASA's Kennedy Space Center. The launch has been delayed since Oct. 10, first to Oct. 13 as Hurricane Milton approached Florida on Wednesday, and now another day due to additional checks in the storm's wake.
"Following Hurricane Milton, teams are continuing to do checkouts to ensure flight readiness," NASA wrote in an update late Friday (Oct. 11). The storm hammered Florida on Wednesday and Thursday. NASA and SpaceX have until Nov. 2 to launch Europa Clipper in the current planetary window, mission managers have said.

"The Damage Assessment and Recovery Team has completed their assessment of the center and its facilities, and determined that employees can safely return on-site to resume working," KSC officials wrote Friday evening on X (formerly Twitter). "The damage identified is manageable and in-line with the items the Ride Out Teams previously identified, including minor impacts such as ripped awning, and damage to doors and traffic lights."
