Ideas to Make Space Shuttle Project



Dr. Porco believes that the icy moon, with its underground liquid sea of water, organics, as well as an energy source, may potentially host life similar to that found in analogous environments on Earth. The March 2012 images of Cassini's "tiger stripes" revealed that these cracks widen and narrow, as was suspected from pictures taken previously. The fissures also change over time more frequently than was originally thought. The two opposite sides of the fissures move laterally relative to one another. This is analogous to the way two banks of the San Andreas Fault can move forward and back, as well as in opposite directions. The greatest slipping and sliding happens when Enceladus is closest to Saturn--as scientists expected. "The near-side of the Moon has been studied for centuries, and yet continues to offer up surprises for scientists with the right tools. We interpret the gravity anomalies discovered by GRAIL as part of the lunar magma plumbing system--the conduits that fed lava to the surface during ancient volcanic eruptions," Dr. Maria Zuber explained in an October 1, 2014 NASA Press Release. Dr. Zuber is from the Massachusetts Institute of Technology (MIT) in Cambridge. "Impact simulations indicate that impacts into a hot, thin crust representative of the early Moon's near-side hemisphere would have produced basins with as much as twice the diameter as similar impacts into cooler crust, which is indicative of early conditions on the Moon's far-side hemisphere," noted lead study author Dr. Katarina Milijkovic in the November 7, 2013 JPL Press Release. Dr. Milijkovic is of the Institut de Physique du Globe de Paris.
