NASA’s Europa Clipper probe is lastly on its approach to the icy ocean moon of Jupiter, however it is going to take a while to get there — about six years. Happily, we do not have to attend that lengthy to get close-up seems to be at Europa.
NASA not too long ago up to date Europa Trek, an internet portal that offers customers the flexibility to “fly over” the floor of Europa, with a guided tour showcasing and explaining a number of the moon’s geological options. The map contains photographs gathered by Europa Clipper‘s predecessors — Voyager 2, Galileo, and Juno, NASA spacecraft that carried out flybys of the moon.
The guided tour walks you thru the intriguing geological options of Europa, a moon with an icy crust over an enormous ocean thought to have twice the quantity of Earth’s oceans mixed.
Instantly obvious as you fly over the floor are lengthy, darkish traces criss-crossing the moon; these are referred to as linea. “One probably clarification for these options is that these are certainly cracks in Europa’s crust. Energetic cracks flex open and closed with the tidal flexing of Europa because it circles Jupiter,” NASA officers wrote on the Europa Trek tour.

Much less obvious are impression craters. Curiously, there are only some on Europa’s floor. Planetary scientists estimate the age of a celestial physique’s floor by the variety of impression craters they sport; older surfaces have had extra time to collect impacts.
“The dearth of craters on Europa signifies that we’re seeing a contemporary, younger floor on a geologically lively world,” NASA officers wrote. Although Europa itself is considered round 4.5 billion years outdated, its floor is probably going simply 20 million to 180 million years outdated, consistently being renewed by geological exercise.

To take the guided tour of Europa, go to trek.nasa.gov/europa, click on on the “hamburger” icon on the highest left of the display, and choose the “Landforms of Europa” choice. You possibly can, after all, discover the floor by yourself, too.
And if you would like to see extra of our photo voltaic system, you may be glad to know that Europa Trek is only one of greater than a dozen such treks exploring the celestial our bodies right here. Discover the others at NASA’s Photo voltaic System Treks portal, together with our personal moon, the near-Earth asteroids Ryugu and Bennu, and Saturn’s moon Titan.
