The presence of water has long been seen as a key condition for life in planetary environments. Prompted by recent discovery by the NASA's Cassini spacecraft of a water vapor "plume" emanating from Enceladus, one of the Saturnian satellites, radio astronomers wondered how abundant water is in the system of Saturn. The so-called maser emission of water molecules offers the most sensitive and robust way of detecting water vapor at radio wavelengths. This emission is unmistakably recognizable...

U.S. and European space officials are considering proposals to send probes to the outer planets of the solar system. One ambitious plan would send an orbiter to Saturn which would release a lander to the moon Titan. Another plan hopes to see two orbiters sent to Jupiter and to its moons, Europa and Ganymede. In February, Ed Weiler of NASA, and David Southwood of the ESA, will announce which plan will go forward to be discussed more thoroughly. The mission could cost billions of dollars to...

Data collected during several recent flybys of Titan by NASA's Cassini spacecraft have put another arrow in the quiver of scientists who think the Saturnian moon contains active cryovolcanoes spewing a super-chilled liquid into its atmosphere. The information was released Monday during a meeting of the American Geophysical Union in San Francisco, Calif. "Cryovolcanoes are some of the most intriguing features in the solar system," said Rosaly Lopes, a Cassini radar team investigation scientist...

The U.S. space agency says its Cassini spacecraft has detected Saturn's small moon Enceladus is showing signs of ongoing changes at its south polar surface. The National Aeronautics and Space Administration said close views of the southern polar region -- where jets of water vapor and icy particles spew from vents within the moon's distinctive tiger stripe fractures -- provide surprising evidence of Earth-like tectonics. They yield new insight into what may be happening within the fractures,...

SAN FRANCISCO, Dec. 15 /PRNewswire-USNewswire/ -- The closer scientists look at Saturn's small moon Enceladus, the more they find evidence of an active world. The most recent flybys of Enceladus made by NASA's Cassini spacecraft have provided new signs of ongoing changes on and around the moon. The latest high-resolution images of Enceladus show signs that the south polar surface changes over time.

A team of astronomers said on Thursday that supersonic plumes of gas and dust shooting off one of Saturn's moons suggest strong evidence of liquid water, a key building block of life. The new discovery adds to the growing push to further explore the moon Enceladus, as some believe it is one of the solar system's most compelling places for potential life. NASA astronomers estimated through images from the Cassini probe that the mysterious plumes shooting from Enceladus' icy terrain contained...

New images from NASA's Cassini spacecraft reveal a giant cyclone at Saturn's north pole, and show that a similarly monstrous cyclone churning at Saturn's south pole is powered by Earth-like storm patterns. The new-found cyclone at Saturn's north pole is only visible in the near-infrared wavelengths because the north pole is in winter, thus in darkness to visible-light cameras. At these wavelengths, about seven times greater than light seen by the human eye, the clouds deep inside Saturn's...

As major league baseball readies for the World Series, NASA's Cassini team will come to bat twice this month when the spacecraft flies by Saturn's geyser moon, Enceladus. The Oct. 9 flyby is an inside pitch -- the closest flyby yet of any moon of Saturn, at only 25 kilometers (16 miles) from the surface. The Oct. 31 flyby is farther out, at 196 kilometers (122 miles). Scientists are intrigued by the possibility that liquid water, perhaps even an ocean, may exist beneath the surface of...

Lagrangian Point -- In Lagrangian mechanics, a Lagrangian point (or L-point) is one of five positions in space where the gravitational fields of two bodies of substantial but differing mass combine to form a point at which a third body of negligible mass would be stationary relative to the two bodies. Bodies at the L-point will not move relative to the parent bodies if they are not perturbed by other gravitational forces. They are sometimes also referred to as libration points. The...

Saturn's moon Phoebe -- Phoebe is the outermost of Saturn's known moons. Phoebe is almost 4 times more distant from Saturn than its nearest neighbor (Iapetus). It was discovered by William Henry Pickering in 1898. Most of Saturn's moons have very bright surfaces, but Phoebe's albedo is very low (.06), as dark as lampblack. All of Saturn's moons except for Phoebe and Iapetus orbit very nearly in the plane of Saturn's equator. Phoebe's orbit is retrograde, inclined almost 175, and is...

Saturn's moon Titan -- Titan is the planet Saturn's largest moon. It is larger than either of the planets Mercury or Pluto and is the second-largest moon in the solar system after Ganymede (it was originally thought to be slightly larger than Ganymede, but recent observations have shown that its thick atmosphere caused overestimation of its diameter). Titan was discovered on March 25, 1655 by the Dutch astronomer Christian Huygens, making it one of the first non-terrestrial moons to be...

Saturn's moon Rhea -- Rhea is the second largest moon of Saturn. It was discovered in 1672 by Giovanni Cassini. Rhea is an icy body with a density of about 1.24 gm/cm3. This low density indicates that it has a rocky core taking up less than one-third of the moon's mass with the rest composed of water-ice. Rhea's features resemble those of Dione, with dissimilar leading and trailing hemispheres, suggesting similar composition and histories. The temperature on Rhea is -174°C in direct...

Saturn's moon Helene -- Helene is a moon of Saturn, discovered by Laques and Lecacheux in 1980 from ground-based observations. It is co-oribtal with Dione and located in its leading Lagrangian point (L4) and hence is sometimes referred to as "Dione B". ----- Orbital radius: 377,400 km Diameter: 33 km (36 x 32 x 30) Mass: Unknown Orbital period: 2.7369 days Orbital inclination: 0.2 ----- NASA Learn more on this topic from eLibrary here:
