Moon's Interior Was Pulverized By Early Impacts
2012-12-05 13:28:06

[ Watch the Video: GRAIL's Gravity Tour of the Moon ] Lee Rannals for redOrbit.com - Your Universe Online Scientists using data from NASA's GRAIL mission have determined that the Moon's interior is nearly completely pulverized. The latest finding from the Gravity Recovery and Interior Laboratory (GRAIL) mission suggests that during the Moon's first billion years, it may have endured more fracturing from massive impacts than previously thought. Planetary scientists have stitched...

Cassini Data Indicates Saturn’s Moon Titan Is Icier Than Thought
2012-12-04 08:44:39

Lawrence LeBlond for redOrbit.com - Your Universe Online Titan, Saturn´s largest moon, has long been projected as an icy body with a vast ocean of liquid water underneath its crust. A recent analysis suggested that heat generated from within the natural satellite helps keep this ocean from freezing due to interactions it has with Saturn and the other moons. And now, a new analysis of the moon´s topography and gravity indicates that its icy outer crust is twice as dense as...

Ganymede Images Captured By Amateur Astronomer
2012-09-28 04:13:56

Lee Rannals for redOrbit.com - Your Universe Online Astronomers reported at the European Planetary Science Congress that they have produced the first amateur albedo map of Jupiter's moon Ganymede. This map shows off the higher areas of reflectivity on an object's surface, recording where material is bright or darker in areas. The map developed by the astronomers closely aligns with professional images of Ganymede's surface, showing off features like Phrygia Sulcus and the Nicholson...

Jupiter Moon Europa
2012-09-25 07:14:23

Lee Rannals for redOrbit.com - Your Universe Online Researchers announced at the European Planetary Science Congress in Madrid on Tuesday that the liquid water found on one of Jupiter's moons may not always be in that state. Europa is believed to be hosting a subsurface ocean of liquid water beneath, but a new study suggests that this water does not stay in this liquid state for longer than a few tens of thousands of years. Astronomers believe the moon contains a water shell about 62...

Russia Considering Cooperation In JUICE Jupiter Mission
2012-07-25 05:25:46

Lee Rannals for redOrbit.com - Your Universe Online The Russian space agency is considering participating in a developing project to send a spacecraft to Jupiter. The European Space Agency (ESA) is starting-up the Jupiter Icy Moon Explorer (JUICE) project, and Russian scientists are considering the possibility of participating, according to a Voice Of Russia report. Lee Fletcher from JUICE´s Oxford University scientific group presented the objectives of the mission at the...

What's Heating Up Io?
2012-06-11 07:45:48

A new study finds that the pattern of heat coming from volcanoes on Io's surface disposes of the generally-accepted model of internal heating.  The heat pouring out of Io's hundreds of erupting volcanoes indicates a complex, multi-layer source.  These results come from data collected by NASA spacecraft and ground-based telescopes and appear in the June issue of the journal Icarus. A map of hot spots, classified by the amount of heat being emitted, shows the global distribution...

Satellite -- A satellite is an object that orbits another object. With sufficient tangential velocity, the object does not collide with the primary object it orbits, but maintains a distance from that object as the rate at which it falls towards that object is similar to the rate that it travels away, thus the object orbits the primary object and becomes a satellite. In other words: gravitational force serves as the centripetal force needed to make the object circle the primary...

Galileo Probe -- The Galileo probe was an unmanned probe sent by NASA to study the planet Jupiter and its moons. Named after the astronomer Galileo Galilei, it was launched on October 18 1989 by the Space Shuttle Atlantis and arrived at Jupiter on December 7 1995. Galileo's launch had been significantly delayed by the hiatus in Space Shuttle launches that occurred after the Space Shuttle Challenger disaster, and new safety protocols that were implemented as a result forced Galileo to use...

Retrograde Motion -- Retrograde motion is the orbital motion of a body in a direction opposite that which is normal to spatial bodies within a given system. 'Retrograde' derives from the Latin words retro, backwards, and gradus, step. In the Solar system, mostly everything rotates in the same sense: all major planets orbit the Sun counterclockwise as seen from the pole star (Polaris). Most planets spin in the same sense, including Earth. The same happens with the orbital motions of the...

Planetary Ring -- A planetary ring is a ring of dust and other small particles orbiting around a planet in a flat disc-shaped region. The most spectacular and famous planetary rings are those around Saturn, but all four of the solar system's gas giant planets (Jupiter, Saturn, Uranus, Neptune) possess ring systems of their own. The origin of planetary rings is not precisely known, but they are thought to be unstable and dissipate over the course of tens or hundreds of millions of...

Jupiter's Moon Himalia -- Himalia is Jupiter's tenth moon. Himalia is 110 miles (170 km) in diameter and orbits 7,000,000 miles (11,480,000 km) from Jupiter. Himalia has a mass of 9.5 x 1018kg. It orbits Jupiter in 250.5662 (Earth) days. Very little is known about Himalia. Himalia was discovered by C. Perrine in 1904. Orbital eccentricity is 0.15798. Orbital inclination is 27.63 degrees. Orbital period is 250.5662 days. Rotational period is 0.4 day. ----- NASA...
