NASA: Jupiter Moon Ganymede May Have Layered Oceans That Support Life – Continuous Disclosure
5/11/2014 6:18:12 PM
Scientists from a NASA-funded research team performed a computer modeling of Ganymede’s oceans, taking into account for the first time how salt increases the density of liquids under extreme conditions that exist on the planet.
NASA first suspected there might be an ocean on Ganymede in the 1970s. Then, in the 1990s, NASA's Galileo spacecraft mission flew by Ganymede, confirming it did have an ocean extending to depths of hundreds of miles. The Galileo mission also found evidence of salty seas, which may contain magnesium sulfate.
Scientists then thought Ganymede had a thick ocean sandwich between just two layers of ice. However, the new research suggests there may be more layers than that.
The research first appeared last year in the journal Planetary and Space Science and was led by Steve Vance of NASA's Jet Propulsion Laboratory in Pasadena, California.
Ganymede boasts a lot of water, perhaps 25 times the volume of the earth's oceans. The moon’s oceans are also estimated to be up to 800 kilometers deep.
The makeup of its deep oceans could be something like a layer of ice at the top, a layer of water below that, then a second layer of ice, followed by another layer of water, then a layer of ice and a final layer of water at the bottom.
"This is good news for Ganymede. Its ocean is huge, with enormous pressures, so it was thought that dense ice had to form at the bottom of the ocean. When we added salts to our models, we came up with liquids dense enough to sink to the sea floor," said Vance.
Salty water sloshing about on top of rock may provide conditions suitable for microbial life. Some scientists have predicted that life on Earth may have formed in bubbling thermal vents on the ocean floor.
Ganymede is just one of five moons in our solar system thought to support vast oceans hidden beneath icy crusts. The others are Jupiter's Europa and Callisto, and Saturn's Titan and Enceladus.
The European Space Agency is developing a mission to visit Europa, Callisto, and Ganymede. The mission is currently scheduled for a 2022 launch, and is expected to reach Jupiter in 2030. NASA plans to contribute instruments to it.
