The Alien Ocean NASA'S Misson to Europa Video

NASA's planned Europa mission would conduct detailed reconnaissance of Jupiter's moon Europa and consider whether the icy moon could harbor conditions suitable for life.
The mission would place a spacecraft in orbit around Jupiter in order to perform a detailed investigation of the giant planet's moon Europa -- a world that shows strong evidence for an ocean of liquid water
beneath its icy crust and which could host conditions favorable for life. The mission would send a highly capable, radiation-tolerant spacecraft into a long, looping orbit around Jupiter to perform repeated close flybys of Europa.

NASA has selected nine science instruments for a future mission to Europa. The selected payload includes cameras and spectrometers to produce high-resolution images of Europa's surface and
determine its composition. An ice penetrating radar would determine the thickness of the moon's icy shell and search for subsurface lakes similar to those beneath Antarctica's ice sheet. The mission would
also carry a magnetometer to measure the strength and direction of the moon's magnetic field, which would allow scientists to determine the depth and salinity of its ocean.
A thermal instrument would survey Europa's frozen surface in search of recent eruptions of warmer water at or near the surface, while additional instruments would search for evidence of water and tiny
particles in the moon's thin atmosphere. NASA's Hubble Space Telescope observed water vapor above the south polar region of Europa in 2012, providing potential evidence of water plumes. If the plumes'
existence is confirmed - and they're linked to a subsurface ocean - studying their composition would help scientists investigate the chemical makeup of Europa's potentially habitable environment while minimizing the need to drill through layers of ice.
The nominal Europa mission would perform 45 flybys of Europa at altitudes varying from 1700 miles to 16 miles (2700 kilometers to 25 kilometers) above the surface.
