The Cassini spacecraft has successfully completed its deepest dive through the water vapour geysers of Enceladus and is now sending back some fantastic images of the event. These and subsequent images, as well as science data still to come, will help scientists better understand the incredible active geology occurring on this tiny, cold moon of Saturn.
Today, Wednesday, Oct. 28, 2015, the Cassini spacecraft will make a historic close flyby (dubbed “E21”) of Saturn’s tiny icy moon Enceladus, not only passing very close to the surface, but also making the deepest dive yet through the water vapour geysers which erupt from the south pole. These plumes are connected to a global ocean of salty water deep below the surface ice, which may be a habitable environment for some form of life.
The Cassini spacecraft has just successfully completed the first of three final close flybys of Saturn’s moon Enceladus, and has sent back some spectacular images of the northern regions of this icy and watery world, the best views ever seen so far. Two more upcoming flybys will dive back into the water vapor plumes at the south pole and measure how much heat is emanating from the tiny moon’s interior.
Starting yesterday, the Cassini spacecraft is making the first of three scheduled close flybys of the moon Enceladus, which will provide the first good look at the north polar region of the tiny, water-spraying moon. These will be the final close-up views of this fascinating world during Cassini’s mission, and may help scientists to better understand the potential habitability of Enceladus, which has become a primary target of interest in the search for evidence of life elsewhere.
Along with Jupiter’s moon Europa, Saturn’s moon Enceladus is considered to be one of the best places to look for evidence of life elsewhere in the Solar System, since both moons are now known to have liquid water beneath their icy surfaces. Now, new evidence suggests that Enceladus may be an even better candidate than first thought: data from the Cassini orbiter shows that the moon harbors a global ocean of water beneath the ice crust, just like Europa, instead of a smaller sea beneath the south pole as previously believed.
