NASA’s Juno Provides High-Definition Views of Europa’s Icy Shell
WEB19 hours ago · A giant ocean is thought to reside below Europa’s icy exterior, and these surface features have been associated with “true polar wander,” a theory that Europa’s outer ice shell is essentially free-floating and moves. “True polar wander occurs if Europa’s icy shell is decoupled from its rocky interior, resulting in high stress levels on the shell, …
Europa: Facts - NASA Science
WEBScientists think Europa’s ice shell is 10 to 15 miles (15 to 25 kilometers) thick, floating on an ocean 40 to 100 miles (60 to 150 kilometers) deep. So while Europa is only one-fourth the diameter of Earth, its ocean may contain twice as much water as Earth’s global ocean.
Through Thick or Thin: Exploring Europa's Outer Layer of Ice
WEB3 days ago · The Europa Orbiter is tentatively scheduled to arrive at Jupiter in 2010, and settle into a 200-kilometer orbit about Europa in 2011 or 2012. The proposed Orbiter will use radar to measure the thickness of the ice crust and to determine whether liquid water exists below the ice.
NASA's Juno provides high-definition views of Europa's icy shell - Phys.org
WEB18 hours ago · Images from the JunoCam visible-light camera aboard NASA's Juno spacecraft supports the theory that the icy crust at the north and south poles of Jupiter's moon Europa is not where it used to be.
FAQ | Mission – NASA's Europa Clipper
WEBSlightly smaller than Earth's Moon, Europa is primarily made of silicate rock and has a water-ice crust and probably an iron-nickel core. It has a very thin atmosphere, composed primarily of oxygen. Its surface is striated by cracks and streaks, but …
Europa Up Close | Why Europa – NASA's Europa Clipper
WEBJupiter’s moon Europa has an icy crust covering a vast, global ocean. The rocky layer underneath may be hot enough to melt, leading to undersea volcanoes. Europa's Interior May Be Hot Enough to Fuel Seafloor Volcanoes
Evidence for an Ocean | Why Europa – NASA's Europa Clipper
WEBBased on Europa's icy composition, scientists think the most likely material to create this magnetic signature is a global ocean of salty water. Europa Clipper will seek to confirm the presence of its ocean.
Juno Provides High-Definition Views of Europa’s Icy Shell
WEB1 day ago · Imagery from the solar-powered spacecraft shows some intriguing features on the ice-encased Jovian moon. Images from the JunoCam visible-light camera aboard NASA’s Juno spacecraft supports the theory that the icy crust at the north and south poles of Jupiter’s moon Europa is not where it used to be.
NASA Study Suggests Shallow Lakes in Europa’s Icy Crust Could …
WEBOct 11, 2022 · New research makes hypotheses that NASA’s Europa Clipper can test: Any plumes or volcanic activity at the Jovian moon’s surface are caused by shallow lakes in its icy crust. In the search for life beyond Earth, subsurface bodies of water in our outer solar system are some of the most important targets.
Dynamics of the global meridional ice flow of Europa’s icy shell - Nature
WEBDec 4, 2017 · We present a global ice flow model for Europa composed of warm, soft ice flowing beneath a cold brittle rigid ice crust 3. The model is coupled to an underlying (diffusive) ocean and...
