Ganymede and Jupiter
2014-07-09 05:38:47

April Flowers for redOrbit.com - Your Universe Online Jupiter's moon Ganymede is the largest satellite in our solar system, approximately three-quarters the size of Mars. Ganymede has two types of terrain on the surface: highly cratered dark regions comprising nearly 40 percent of the surface, with the rest being lightly grooved in intricate patterns. A new study, led by researchers with the Southwest Research Institute (SwRI), reveals that the processes which shaped these ridges and...

redOrbit Staff & Wire Reports - Your Universe Online If there are cracks on the ice-covered surface of Charon, an upcoming analysis of those fractures could help determine whether or not the interior of Pluto’s moon was warm enough to have been home to a subterranean ocean of liquid water. In April, research funded by the US space agency and published in the journal Icarus reported how tidally-driven fractures could have formed on the moon if its orbit was previously eccentric....

redOrbit Staff & Wire Reports - Your Universe Online While astronomers have long believed that Jupiter’s moon Ganymede was home to a thick ocean sandwiched between two layers of ice, a new NASA-funded research project now claims that the largest natural satellite in our solar system could actually have several layers of ice and ocean stacked one upon another. Writing in the journal Planetary and Space Science, Steve Vance of the Jet Propulsion Laboratory (JPL) in Pasadena,...

NASA Looking For External Concepts For Mission To Oceanic Jovian Moon
2014-04-29 03:21:27

Dwayne Brown, NASA's Jet Propulsion Laboratory NASA has issued a Request for Information (RFI) to science and engineering communities for ideas for a mission to Europa that could address fundamental questions of the enigmatic moon and the search for life beyond Earth. The RFI's focus is for concepts for a mission to Europa that costs less than $1 billion, excluding the launch vehicle that can meet as many of the science priorities as possible recommended by the National Research...

[ Watch the Video: Crater Identification Variability Using Citizen Scientists ] April Flowers for redOrbit.com - Your Universe Online Astronomers believe that Europa, one of Jupiter's moons, has a huge ocean beneath its icy surface. They have theorized that water, salts and gasses that have dissolved into that ocean rise to the surface, generating the enigmatic geological formations associated with the red-tinged formations seen on the moon's surface. A group of researchers from the...

Jupiter Moon Mission Planned By NASA
2014-03-05 14:19:48

Lee Rannals for redOrbit.com - Your Universe Online NASA is developing a new mission for 2015 that would send a spacecraft to Jupiter’s moon Europa to investigate whether the moon contains conditions suitable for life. Europa is an icy moon that scientists believe could hold an ocean of liquid water beneath its icy crust. If an ocean can be found underneath Europa’s crust, it means the moon could have conditions favorable for life. Essentially, where there is water there is a...

Voyager, Galileo Spacecraft Images Used To Create Geological Map Of Jupiter's Largest Moon
2014-02-12 15:57:52

[ Watch the Video: Rotating Globe of Ganymede Geology ] Lee Rannals for redOrbit.com - Your Universe Online Scientists, led by Geoffrey Collins, of Wheaton College, have produced the first global geological map of Jupiter’s largest moon. The map, now published by the USGS as a global map, combines images of Ganymede taken by NASA's Voyager 1 and 2 spacecraft and Galileo orbiter. It is the first global, geologic map of Jupiter’s seventh moon, providing the geologic character of...

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...
