The Sun and our neighboring planet Mars are two destinations that the UK and US will be exploring together in the coming years, following recent agreements for collaboration on three big space projects. During a visit this week to space facilities and companies in the UK, Mason Peck, Chief Technologist at NASA, said, “Cooperation and collaboration are critical to meet increasingly global challenges, and our partnership with the United Kingdom in space exploration and technology...

Monster Storm On Saturn Captured By Cassini
2013-04-29 13:26:47

[ Watch the Video: Mysterious Hurricane at Saturn´s North Pole ] Lee Rannals for redOrbit.com - Your Universe Online NASA's Cassini spacecraft has provided an incredible view of a monster storm on Saturn with clouds moving as fast as 300 miles per hour. High-resolution pictures and video of the storm gives a unique perspective of a hurricane with an eye measuring about 1,250 miles, which is about 20 times larger than the average hurricane eye on Earth. NASA said the hurricane is...

WASHINGTON, April 25, 2013 /PRNewswire-USNewswire/ -- NASA's Cassini spacecraft has provided the first direct evidence of small meteoroids breaking into streams of rubble and crashing into Saturn's rings. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO ) These observations make Saturn's rings the only location besides Earth, the moon, and Jupiter where scientists and amateur astronomers have been able to observe impacts as they occur. Studying the impact rate of meteoroids from...

Meteoroids Slam Into Saturn’s Rings
2013-04-25 15:08:34

Lee Rannals for redOrbit.com — Your Universe Online NASA said on Thursday that its Cassini spacecraft provided the first direct evidence of small meteoroids crashing into Saturn's rings. Previously, scientists had only witnessed impacts on Earth, the moon and Jupiter as they occurred. Studying the impact rate of meteorites outside the Saturnian system helps scientists understand how different planetary systems in our Solar System formed. The meteoroids that impacted Saturn are...

Cassini Mission Tracks Vanishing Methane On Saturn's Moon Titan
2013-04-16 07:20:00

Lawrence LeBlond for redOrbit.com - Your Universe Online Part of the surface of Saturn´s moon Titan has been actively tracked by NASA´s Cassini mission for the past several years. During that time, the mission has found a remarkable presence of hydrocarbon methane lakes and seas dotting the surface of the moon. But a model developed by mission leaders at the Jet Propulsion Laboratory (JPL) in Pasadena, California, suggests the supply of these methane lakes will soon come to end....

Changing Seasons On Titan
2013-04-12 07:40:24

April Flowers for redOrbit.com - Your Universe Online The latest sign that the change of seasons has started a cascade of radical changes in the atmosphere on Titan is an ice cloud taking shape over the south pole. This type of cloud, made from unknown ice, has long hung over the north pole. According to observations by the composite infrared spectrometer (CIRS) on NASA's Cassini spacecraft, the northern cloud is now fading. "We associate this particular kind of ice cloud with winter...

How Charged Water Particles Affect Saturn's Atmosphere
2013-04-10 19:36:15

Lee Rannals for redOrbit.com — Your Universe Online A new study published in the journal Nature found that the "rain" of charged water particles in Saturn's atmosphere influences the composition and temperature of the planet's upper atmosphere and rings. The study, led by the University of Leicester in England, reveals that there is a significant interaction between its atmosphere and ring system. "The main effect of ring rain is that it acts to 'quench' the ionosphere of...

Saturn’s Moon Telesto Discovered 33 Years Ago Today
2013-04-08 18:47:23

Lee Rannals for redOrbit.com — Your Universe Online Thirty-three years ago today, astronomers discovered Saturn's moon Telesto using ground-based observations. Astronomers Bradford A. Smith, Harold Reitsema, Stephen M. Larson and John W. Fountain were performing ground observations on April 8, 1980 when they discovered the Saturn moon. The moon was officially named after Telesto of Greek mythology, but was also designated as Saturn XIII or Tethys B. NASA said Telesto is known...

Cassini Shows Saturn As An Antique Shop
2013-03-27 18:43:08

Lee Rannals for redOrbit.com — Your Universe Online NASA's Cassini spacecraft has unveiled new data about how Saturn's moons and rings are like an antique shop. Gianrico Filacchione, a Cassini participating scientist at Italy's National Institute for Astrophysics, Rome, published a paper online in The Astrophysical Journal about how Saturn's moons and rings are gently worn, vintage goods from around the time of our solar system's birth. He suggests these bodies date back more...

Cassini-Huygens Mission -- The Cassini unmanned space probe is intended to study Saturn and its moons. It was launched on October 15, 1997 and is estimated to enter Saturn's orbit on July 1, 2004. The mission is a joined NASA/ESA project. Cassini's principal objectives are to: -- determine the three-dimensional structure and dynamical behavior of the rings -- determine the composition of the satellite surfaces and the geological history of each object -- determine the nature and...

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...

The Planet Saturn -- in astronomy, 6th planet from the sun. Astronomical and Physical Characteristics of Saturn Saturn's orbit lies between those of Jupiter and Uranus; its mean distance from the sun is c.886 million mi (1.43 billion km), almost twice that of Jupiter, and its period of revolution is about 291/2 years. Saturn appears in the sky as a yellow, starlike object of the first magnitude. When viewed through a telescope, it is seen as a golden sphere, crossed by a series of...
