Jupiter Europa Essay

1529 words - 7 pages

Europa is the sixth of Jupiter's moons and the fourth largest. Europa is named after a Phoenician princess who was abducted by Zeus and taken to the island of Crete to be his lover. Europa was discovered by Galileo Galilei and possibly Simon Marius in 1610 and is one of the four Galilean satellites. The others being: Io, Ganymede, and Callisto. Europa is very different from the other moons of Jupiter. Instead of a rocky, cratered surface like Callisto and Ganymede, it instead has a smooth outer surface of cracked ice. There are very few sign of craters on Europa. In fact, only three large craters have been found. This indicates that Europa's surface is very young and active.

The Jupiter Europa Orbiter (JEO) was a proposed orbiter probe planned for detailed studies of Jupiter's moon Europa. Its main goal was to look for evidence of a possible subsurface ocean. The objectives of this mission were to to determine whether the Jupiter system harbors habitable environments. The main science objectives supporting this goal are: to characterize sub-surface oceans, to characterize the ice shells and any subsurface water, and to find sources where life may be possible.
Slightly smaller than the Moon, Europa is primarily made of silicate rock and probably has an iron core. It has a tenuous atmosphere composed primarily of oxygen. Its surface is composed of water ice and is one of the smoothest in the Solar System. Its surface is striated by cracks and streaks, whereas craters are relatively rare. The apparent youth and smoothness of the surface have led to the hypothesis that a water ocean exists beneath it, which could conceivably serve as an dwelling for extraterrestrial life. This hypothesis proposes that heat from tidal flexing causes the ocean to remain liquid and drives geological activity similar to plate tectonics. Most planetary scientists believe that a layer of liquid water exists beneath Europa's surface, and that heat energy from tidal flexing allows the subsurface ocean to remain liquid. Europa's surface temperature averages about 110 K at the equator and only 50 K at the poles, keeping Europa's icy crust as hard as granite. The first hints of a subsurface ocean came from theoretical considerations of tidal heating.
In late 2008, it was suggested Jupiter may keep Europa's oceans warm by generating large planetary tidal waves on Europa because of its small but non-zero abnormality. These tidal waves can generate significant kinetic energy. The existence of the spontaneous movement requires a layer of a highly electrically conductive material in Europa's interior. The most plausible candidate for this role is a large subsurface ocean of liquid saltwater. Spectro-graphic evidence suggests that the dark, reddish streaks and features on Europa's surface may be rich in salts such as magnesium sulfate, deposited by evaporating water that emerged from within. Sulfuric acid hydrate is another possible explanation for the contaminant observed spectroscopically.
Europa has emerged as one of the top locations in the Solar System in terms of potential habitability and the possibility of hosting extraterrestrial life. Life could exist in its under-ice ocean, perhaps subsisting in an environment similar to Earth's deep-ocean hydrothermal vents. Life in such an ocean could possibly be similar to microbial life on Earth in the deep ocean. Scientists have discovered colonies of giant tube worms, clams, crustaceans, mussels, and other assorted creatures clustered around undersea volcanic features known as black smokers. These creatures thrive despite having no access to sunlight, and it was soon discovered that they...

The Search for Life in Europa

612 words - 3 pages Europa was discovered alongside the other Jovian moons of Jupiter (Io, Ganymede, Callisto) by Galileo Galilei on January 8th, 1610. It is the Sixth closest moon to planet Jupiter and sixth largest moon in the Solar System. It takes Europa roughly every 3.5days to orbit Jupiter and spins just once per orbit which is why it shows the same face to Jupiter all the time (similar to Earth’s moon). It is also roughly the size of earth’s moon

The moon Europa and its possible oceans under the ice shell are the most likely candidate. Scientists think that underwater thermal vents like those found at the extreme depths of some of Earth's oceans might harbor life as well. Future exploration could possibly answer these questions. Maybe Mars isn't the best hope for life out there.References
