Mini Rocket Models Used In Big Way For Space Launch System Base Heating Test
2014-03-06 14:29:37

[ Watch The Video: Models Helping Engineers Better Understand Heat ] Megan Davidson, NASA To better understand the heating conditions at the base of what will be the biggest, most powerful rocket ever built, engineers at NASA's Marshall Space Flight Center in Huntsville, Ala., are thinking small -- really small. Models of NASA's Space Launch System (SLS) core stage RS-25 engines and solid rocket boosters -- scaled down to just 2 percent of the actual size of the flight hardware...

Cassini Nears 100th Titan Flyby
2014-03-06 09:16:49

NASA Ten years ago, we knew Titan as a fuzzy orange ball about the size of Mercury. We knew it had a nitrogen atmosphere -- the only known world with a thick nitrogen atmosphere besides Earth. But what might lie beneath the hazy air was still just a guess. On March 6, NASA’s Cassini spacecraft will swoop down within 933 miles (1,500 kilometers) of Titan to conduct its 100th flyby of the Saturn moon. Each flyby gives us a little more knowledge of Titan and its striking similarities to...

NASA Spacecraft Capture Stunning Views Of Saturn's Dancing Auroras
2014-02-11 13:22:13

[ Watch the Video: Saturn Puts On Quite A Light Show ] Lee Rannals for redOrbit.com - Your Universe Online Two NASA spacecraft captured 360 degree views of Saturn’s northern lights, giving a glimpse as to how the ringed planet looks when bathed in the Sun’s charged particles. Using the Hubble Space Telescope and Cassini, NASA collaborated along with international researchers to put together the footage of the Saturnian show. Hubble provided an ultraviolet wavelength view of the...

Saturn And Moons Show Off For The Holidays
2013-12-24 04:10:50

redOrbit Staff & Wire Reports - Your Universe Online Just in time for the holiday season, NASA’s Cassini spacecraft has captured new images of Saturn and two of its moons – including Enceladus, a “white, glittering snowball of a moon,” the US space agency announced on Monday. Featured in the collection of newly-released images (which can be viewed online) are two views of Enceladus that highlight the several ridges and features that highlight the surface of the icy moon. The...

Titan - The Extraterrestrial Land of Lakes
2013-12-13 04:43:25

[ Watch the Video: Soaring Over Titan: Extraterrestrial Land of Lakes ] redOrbit Staff & Wire Reports - Your Universe Online Thanks to NASA’s Cassini spacecraft, astronomers are gaining new insights into Saturn’s moon Titan, particularly when it comes to its hydrocarbon lakes and seas. According to the US space agency, Titan is one of the most Earth-like entities in the entire solar system. Besides our planet, the moon is the only other place in the Milky Way that has stable...

Hubble Finds Europa Water Vapor
2013-12-12 13:10:28

[ Watch the Video: Europa Shows Evidence Of Liquid Water ] Brett Smith for redOrbit.com - Your Universe Online For years scientists have suspected the presence of liquid water under the surface of Jupiter’s moon Europa. Now, the Hubble Space Telescope has detected evidence of water vapor eruption from the moon’s surface, according to a new report published in Science Express on Thursday. The space agency is looking to observations from other sources to confirm Hubble’s initial...

Cassini High Res Video Saturn Hexagon Jet Stream
2013-12-04 16:12:07

redOrbit Staff & Wire Reports - Your Universe Online NASA’s Cassini spacecraft has recorded the highest-resolution video to date of a unique six-sided jet stream located near Saturn’s north pole, the US space agency announced. This movie is the first to capture the phenomenon also known as the 'hexagon' using color filters, and is also the first footage to show a complete view of the top of the planet down to approximately 70 degrees latitude, NASA said. “Spanning about...

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...
