NASA’s going to send off a huge spacecraft to a world harboring voluminous seas.

Planetary researchers suspect Jupiter’s moon Europa contains a sea somewhere around two times the size of Earth’s. The Europa Clipper probe which is the length of a basketball court and the biggest art the organization has sent on a planetary mission is scheduled to blast to this far realm on Oct 10. Before the send off, NASA delivered another point by point perspective on the moon’s broken surface, which shows why for quite a long time scientists have been attracted to this tantalizing spot.

“It’s maybe one of the most outstanding spots past Earth to search for life in our planetary group,” Cynthia Phillips, a NASA planetary geologist and project staff researcher for the space agency’s Europa Clipper mission, told Mashable.

On Oct 2, NASA shared the view above, which was taken from data gathered by the Galileo mission in 1998. It shows a nearby of Europa’s chaotic landscape, which is proof that something above the moon’s thick icy crust like a sea is stoking lots of progress and deformity. Salty water might run away to the surface along breaks, leaving telltale reddish colors on Europa’s ground. And irregular, chunks of ice have likely been made by relatively recent surface movement.

“This locale sports ice rafts that seem to be those at Earth’s poles, where huge pieces of ice split away and float openly on the sea,” the organization composed. “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.”

To prove whether a sea exists and if it colud host suitable confitions for life, Europa Clipper will make around 50 close flybys of the moon’s surface. It’s fitted with various high-resolution cameras, a ground-penetrating radar, and, even a gadget (called SUDA) that will in a real sense test particles of Europa that have been launched out into space by tiny meteorites.

After looping through the solar system on a 1.8-billion-mile (2.9 billion-kilometer) journey, the craft will arrive at Europa in 2030, and go spend 3.5 years gathering phenomenal information. To decide whether the Jupiter moon is habitable, mission researchers need to respond to a few significant inquiries. For instance, all life needs energy: Does this sea world give an energy source? And, does it harbor the basic chemical ingredients, like carbon, to form the building blocks of life as we know it? 

And, if all those conditions are satisfied, is there evidence the ocean has been around for billions of years, providing a stable environment for life to evolve and sustain itself in Europa’s dark sea?

We’ll find out.
