For the 50th anniversary NASA has released some beautiful Panoramas pictures of Apollo missions.
With the help NASA’s Cassini spacecraft scientists has discovered that the water geysers erupting from Enceladus contain a significant amount of salt, wich is enough to suggest the presence of a subterranean sea. Saturn’s moon Enceladus, orbiting a planet about 891 million miles (1.4 billion km) from the sun, is cold and frigid on its surface.Cassini’s data show the grains expelled from fissures, known as tiger stripes, are relatively small and predominantly low in salt far away from the moon. But closer to the moon’s surface, Cassini found that relatively large grains rich with sodium and potassium dominate the plumes.
The salt-rich particles have an “ocean-like” composition and indicate that most, if not all, of the expelled ice and water vapor comes from the evaporation of liquid salt water. The data suggest that a layer of water between the moon’s rocky core and its icy mantle, possibly as deep as about 50 miles (80 kilometers) beneath the surface.Scientists belive that their new finding can have effects for the possibility of life on Saturn’s moon Enceladus.
