  1. EUROPA

  2. What is europa? • Galilean satellite • Smallest of the Galilean moons • 6th largest moon in the solar system • First to show possibility of life other than earth

  3. Stats • Discovered by Galileo Galilei in 1610 • Europa’s mass is 4.7998 x 10²² kg • Surface area is 30,612,893 km² • Volume is 15,936,867,918 kmᶾ • Surface gravity is 1.315 m/s² • Europa's surface temperatures range from -160C to -220C (-260F to -370F)

  4. Atmosphere • Very thin atmosphere • Ions from Jupiter’s magnetosphere hit the surface and break apart the water molecules • Hydrogen escapes into space leaving oxygen behind

  5. Europa’s ocean • Layer of thin ice all over • Underground ocean • http://www.redorbit.com/news/video/space_2/1113019578/europa-subsurface-ocean-120413/

  6. orbit • Orbit size around Jupiter is 672,100 km or 417,002 miles (distance from Jupiter) • The same side of Europa always faces Jupiter. It takes the same amount of time to make one revolution on its axis as it does to complete an orbit around Jupiter. • Sidereal rotation period (length of a day) 3.551 Earth Days • Orbit Circumference is 4,216,552 km • Average orbit velocity is 49,476 km/hr • Orbit inclination is 0.466 degree

  7. Orbit cont’d • Orbit is eccentric • When close to Jupiter higher tidal forces and when farther lower tides • The sea under is going high and low possibly causing the cracks we see in the ice on the surface

  8. Anatomy • Made up primarily of silicate rock and iron. • Surface is composed of water ice • Scientist believe there is salt water underneath the frozen surface • Hypothesis believe that there is extraterrestrial life within the water • Hubble Space Telescope discovered that Europa has water vapor plumes that can reach 200 km high, more than 20x the height of Mt. Everest • Oceans are 100 miles deep with only a few miles of frozen ice protecting it • The lines on the surface of Europa are cracks in the ice with some reaching 1,850 miles long

  9. Life on europa • Scientist believe that life could be on Europa because the strong tidal heat could keep the inside warm to have liquid under the ice layer • Kevin hand from nasa’s jet propulsion lab said,  "If we've learned anything about life on Earth, it's that where there's liquid water, there's generally life."

  10. New findings • NASA’s Hubble space telescope observed water vapors above the frigid south polar region , first strong evidence of water plumes erupting from the surface

  11. Fun facts • Next mission is the European space agencies Jupiter icy moon explorer (JUICE) due to launch in 2022 • There is actually a movie called EUROPA REPORT about a mission that goes to europa to search for life
