Last Close Flyby Of Saturnian Moon Rhea Made By Cassini
2013-03-08 08:57:45

NASA NASA's Cassini spacecraft will be swooping close to Saturn's moon Rhea on Saturday, March 9, the last close flyby of Rhea in Cassini's mission. The primary purpose will be to probe the internal structure of the moon by measuring the gravitational pull of Rhea against the spacecraft's steady radio link to NASA's Deep Space Network here on Earth. The results will help scientists understand whether the moon is homogeneous all the way through or whether it has differentiated into the...

Cassini Spies On Earth's Sister Venus From Behind Saturn's Rings
2013-03-04 13:54:02

Lee Rannals for redOrbit.com — Your Universe Online The international Cassini spacecraft, a NASA, European Space Agency (ESA) and Italian Space Agency (ASI) jointly-operated project, has taken some unique pictures of Earth's twin planet from the perspective of Saturn. The Cassini-Huygens mission launched on October 15, 1997, traveling 2.2 billion miles toward Saturn, reaching the distant ringed-planet June 30, 2004. The orbiter includes 18 sophisticated science instruments to help...

Cassini Catches Solar Wind, Helps NASA Study Particle Acceleration
2013-02-20 14:23:12

Michael Harper for redOrbit.com — Your Universe Online As it floats around the planet Saturn, the Cassini spacecraft recently got a front row seat to what NASA astronomers are calling an “unusual strong blast of solar wind.” Shortly after this “wind” blew by, Cassini began detecting particles which had been accelerated to ultra-high energies. Particles which are accelerated this much are usually found surrounding far away supernovas. This is good news for...

Cassini Records Possible Supernova Shockwave On Saturn
2013-02-18 16:08:11

Lee Rannals for redOrbit.com - Your Universe Online For the first time, scientists from the international Cassini spacecraft have detected subatomic particles that have been accelerated to ultra-high energies in a blast of solar wind around Saturn, hinting at the possibility that the ringed planet may have experienced the aftermath of a supernova. According to a report by the European Space Agency (ESA) that appeared recently in the journal Nature Physics, this acceleration may be the...

Smog Detected At Northern Hemisphere Of Saturn Moon Titan
2013-02-05 08:33:50

April Flowers for redOrbit.com - Your Universe Online An international group of scientists, led by Panayotis Lavvas of the University of Reims, Champagne-Ardenne, used data from NASA's Cassini mission to describe, in unparalleled detail, how aerosols in the highest part of the atmosphere are kick-started on Saturn's moon Titan. The study, published in a recent issue of Proceedings of the National Academy of Sciences (PNAS), seeks to understand aerosol formation at Titan because it could...

Six Month Saturn Storm Eats Itself
2013-01-31 19:48:37

Lee Rannals for redOrbit.com — Your Universe Online Cassini mission scientists have observed a huge thunder-and-lightning storm on Saturn consume itself for the first time. The NASA scientists said in a paper published in the journal Icarus that they observed as the massive storm made its way around the planet, until it ran into its own tail and dissipated. "This Saturn storm behaved like a terrestrial hurricane - but with a twist unique to Saturn," Andrew Ingersoll, a Cassini...

Lack Of Craters On Titan Makes Moon Look Younger
2013-01-17 15:10:00

Lee Rannals for redOrbit.com — Your Universe Online New research based on observations from NASA's Cassini spacecraft show that Titan, Saturn's largest moon, may look younger than it really is. While most moons display their age through their thousands of craters, NASA said that Titan's craters are being erased, giving it a 'Benjamin Button' appearance. "Most of the Saturnian satellites - Titan's siblings - have thousands and thousands of craters on their surface. So far on...

Huygens Celebrates Eighth Year Since Titan Landing
2013-01-14 10:43:09

[ Watch the Video: The Huygens Experience ] Lee Rannals for redOrbit.com - Your Universe Online Eight years ago today, Huygens became the first probe to touch down on the surface of Saturn's moon Titan. Huygens was first released from the international Cassini spacecraft on Christmas Day 2004, and it arrived at Titan three weeks later. Cassini has been orbiting around Saturn since July 2004, and the spacecraft will continue its operations until 2017. ESA released an animation...

Transit Of Venus Across The Sun Occurs Today
2012-12-21 07:49:58

Lawrence LeBlond for redOrbit.com - Your Universe Online So it´s December 21st and the world is still here. Does that mean the doomsayers were full of baloney? Or did they just misread the warnings? Perhaps the Mayans knew today´s date was special for some other reason than total annihilation. If so, then you may be happy to know they would have been right. Phil Nicholson, a Cornell University scientist said this week that Venus will be making a second transit across the face...

Cassini Captures Stunning Images Of Saturn
2012-12-19 09:59:40

April Flowers for redOrbit.com - Your Universe Online Delivered just in time for the holiday season, another glorious, backlit image of the planet Saturn has arrived from NASA's Cassini spacecraft, which has been in orbit around the planet for more than eight years. Cassini was deliberately positioned within Saturn's shadow during its 174th orbit around the gas giant on October 17, 2012. This positioning made for a perfect location from which to look in the direction of the Sun and...

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...
