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...

NASA Celebrates 40th Anniversary Of Pioneer 11
2013-04-05 14:51:40

[ Watch the Video: Pioneer 11 Animation and Archive Footage ] Michael Harper for redOrbit.com — Your Universe Online NASA is celebrating the 40th birthday of the Pioneer 11 spacecraft. For the past four decades, Pioneer has been hurtling through space, capturing satellite images of the planets Jupiter and Saturn. As its predecessor, Pioneer 10 had launched just over a year before and was the first spacecraft to not only leave the inner Solar System, but make the trip to Jupiter as...

Complex Chemistry Could Lead To Life On Titan
2013-04-03 19:20:52

Lee Rannals for redOrbit.com — Your Universe Online Scientists reported in the journal Nature Communications that complex organic chemistry could eventually lead to the building blocks of life on Saturn's moon Titan. Experiments at NASA's Jet Propulsion Laboratory have shown the same kind of biological chemistry on Earth's surface could also drive chemistry on Titan, even though the Saturn moon receives far less light from the sun and is much colder. "Titan is not a sleeping...

NASA's Crawler-Transporter Receives New Roller Bearing Assemblies
2013-04-03 16:22:51

NASA For more than a year, NASA's crawler-transporter (CT) 2 has been undergoing a major tuneup in the Kennedy Space Center's Vehicle Assembly Building (VAB). Recent work has included preparations to install upgraded components that will enable the crawler to carry the greater loads anticipated with the agency's new rocket designed to take astronauts beyond low-Earth orbit for the first time since the early 1970s. The crawler-transporter modifications are part of NASA's Ground Systems...

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...

Europe-Sized Storm On Venus Monitored By Astronomers Via ESA Spacecraft
2013-03-25 12:47:52

Lee Rannals for redOrbit.com — Your Universe Online Astronomers writing in the journal Nature Geoscience say they have been closely monitoring the movement of a huge whirlwind the size of Europe on Venus. Researchers from Universidad del Pais Vasco (UPV) used an instrument on board the European Space Agency's (ESA) Venus Express spacecraft to monitor the evolution of the south pole vortex. The team monitored the movement of the vortex on two separate main cloud levels in Venus'...

Amazon Founder Jeff Bezos Recovers Apollo-Era F-1 Engines From Atlantic Ocean
2013-03-21 09:22:10

Lawrence LeBlond for redOrbit.com - Your Universe Online Amazon founder and CEO Jeff Bezos last year announced that he would send a team of explorers to hunt out and recover F-1 engines from the historic Apollo 11 moon launch. Just yesterday (Mar 20), Bezos made a new announcement that the team had recovered several engine parts from the bottom of the Atlantic off the coast of Cape Canaveral, yet it is too early to tell if the F-1 engine parts are from the famed Apollo 11 mission. The...

Jupiter’s Hot Spots Move Like A Merry-Go-Round
2013-03-15 12:25:30

Watch the video “Jupiter´s Hot Spots” Brett Smith for redOrbit.com - Your Universe Online Planetary scientists at NASA have found that a weather phenomenon also found in Earth´s atmosphere is responsible for the activity of so-called ℠hot spots´ slightly bigger than North America drifting across Jupiter´s atmosphere. Using images taken by NASA's Cassini spacecraft as it passed Jupiter en route to Saturn, scientists have determined that hot...

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-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...

Gas Giant
2004-10-19 04:45:41

Gas Giant -- A gas giant is a generic astronomical term invented by the science fiction writer James Blish to describe any large planet that is not composed mostly of rock or other solid matter. Gas giants may still have a solid core - in fact, it is expected that such a core is probably required for a gas giant to form - but the majority of its mass is in the form of gas (or gas compressed into a liquid state). Unlike rocky planets, gas giants do not have a well-defined surface. There...

Planet Neptune -- Neptune is the eighth planet from the sun. It is a gas giant. Orbiting so far from the sun, Neptune receives very little heat. Its 'surface' temperature is -218 degrees Celsius (below zero). However, the planet seems to have an internal source of heat. It is thought that this may be leftover heat generated by infalling matter during the planet's birth, now slowly radiating away into space. Neptune's atmosphere has the highest wind speeds in the solar system, up to...

Uranus -- Uranus is the seventh planet from the sun. It is a gas giant. Physical characteristics Uranus is composed primarily of rock and various ices, with only about 15% hydrogen and a little helium (in contrast to Jupiter and Saturn which are mostly hydrogen). Uranus (and Neptune) are in many ways similar to the cores of Jupiter and Saturn minus the massive liquid metallic hydrogen envelope. It appears that Uranus does not have a rocky core like Jupiter and Saturn but rather...

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...
