Voyager Celebrates 36 Years In Space
2013-08-20 15:40:23

Lee Rannals for redOrbit.com - Your Universe Online Thirty-six years ago NASA launched one of the longest missions in the space agency's history, the Voyager 2. The Voyager 2 spacecraft is a sister spacecraft of the Voyager 1 and was designed to explore not only planets like Jupiter, Saturn, Uranus and Neptune, but also the edge of our Solar System. Voyager 2 was able to give NASA an up-close look at Saturn and its moons. The 36-year-old spacecraft made its first flyby of Jupiter...

NASA's Space Launch System Program Preliminary Design Review
2013-08-02 11:34:22

NASA [ Watch The Video - Preliminary Design Review Completed at NASA ] NASA's Space Launch System (SLS) Program recently completed its preliminary design review, commonly referred to as PDR. A quick inquiry of "What is PDR?" on a search engine pulls up everything from dent repairs to a physicians' reference guide on prescription medications. So, what exactly is PDR when you're talking about building the world's most powerful rocket? And why is it important to the future of space...

Traveling To Hard-to-reach Destinations Made Easier Thanks To NASA Technologist
2013-08-01 08:22:27

NASA Traveling to remote locations sometimes involves navigating through stop-and-go traffic, traversing long stretches of highway and maneuvering sharp turns and steep hills. The same can be said for guiding spacecraft to far-flung destinations in space. It isn't always a straight shot. A NASA technologist has developed a fully automated tool that gives mission planners a preliminary set of detailed directions for efficiently steering a spacecraft to hard-to-reach interplanetary...

Saturn Influences Jets Of Enceladus
2013-08-01 05:31:29

April Flowers for redOrbit.com - Your Universe Online The proximity of Saturn's moon Enceladus to the ringed planet can change the intensity of the jets of water ice and organic particles that shoot out from the moon, according to data from NASA's Cassini spacecraft. The findings, published in Nature, add to the growing evidence a liquid water reservoir or ocean lurks under the icy surface of the moon. The Cassini data is the first clear observation the bright plume emanating from...

Pale Blue Dot Shines In Cassini, MESSENGER Images
2013-07-23 08:37:16

Brett Smith for redOrbit.com - Your Universe Online It might look like just one pale blue dot among millions of other similar looking objects, but NASA's Cassini spacecraft recently captured an 'Earth-selfie' from 890 million miles away. The image captured by the Saturn orbiter is actually a look into the past as light from Earth takes 80 minutes to reach the ringed planet. "We can't see individual continents or people in this portrait of Earth, but this pale blue dot is a succinct...

Why Titan Has No Waves
2013-07-22 12:17:42

[ Watch the Video: The Mystery Of The Missing Waves Of Titan ] Lee Rannals for redOrbit.com - Your Universe Online A new study published in the journal Icarus attempts to answer the question of where all the waves went on Saturn's moon Titan. Surprisingly, Titan is a world full of lakes, seas, river channels, islands, rain and mud. However, one of the big differences between this moon and Earth is that Titan's liquid is not water. Titan is far too cold for liquid water, and...

MESSENGER To Capture Earth, Moon In Series Of Images This Weekend
2013-07-19 07:10:22

Lawrence LeBlond for redOrbit.com - Your Universe Online We previously reported the NASA/ESA/ASI Cassini spacecraft was preparing to take an amazing picture of Earth as Saturn encountered a solar eclipse. This event is set to occur late this afternoon between 5:27 and 5:42 pm. The Earth will pose for Cassini, which is more than 900 million miles away, and NASA is encouraging all Americans to go out and photobomb Cassini, and then share their pictures via the Internet. The Cassini images...

Smile And Wave At Saturn!
2013-07-19 04:43:19

Lee Rannals for redOrbit.com - Your Universe Online NASA's Cassini spacecraft, currently orbiting around Saturn, will be poised to snap an image of Earth on Friday, and the space agency is asking the public to photobomb the picture. Cassini will be positioned to take an image of Earth through the rings of Saturn, and NASA is asking everyone to go outside and get in the picture. "Cassini has photographed Earth before, but this will be the first time Earthlings know in advance their...

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...
