[ 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...

Van Allen Probes Helping To Refine Space Weather Computer Models
2014-03-10 07:45:30

redOrbit Staff & Wire Reports - Your Universe Online Data from the Van Allen Probes has been combined with a high-powered computer model to help researchers test and improve the forecast model to determine how the two giant near-Earth radiation belts they orbit can affect technology in space, NASA officials reported on Friday. The Van Allen radiation belts, which are teeming with rapidly-moving particles and a space weather system that varies in response to incoming solar particles...

Lava Floods Mars Ancient Plains
2014-03-06 09:30:21

ESA Two distinct volcanic eruptions have flooded this area of Daedalia Planum with lava, flowing around an elevated fragment of ancient terrain. The images were acquired by ESA’s Mars Express on 28 November 2013 towards the eastern boundary of the gigantic Tharsis Montes volcanic region, where the largest volcanoes on Mars are found. The lava flows seen in this image come from Arsia Mons, the southernmost volcano in the Tharsis complex, which lies around 1000 km to the northwest of...

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...

Galileo Working Well
2014-02-12 12:08:28

[ Watch The Video: Galileo Validated in Orbit VNR ] ESA The in-orbit validation of Galileo has been achieved: Europe now has the operational nucleus of its own satellite navigation constellation in place – the world’s first civil-owned and operated satnav system. In 2011 and 2012 the first four satellites were launched into orbit. Four is the minimum number needed to perform navigation fixes. In the following year, these satellites were combined with a growing global ground...

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...

Jupiter's Moon Callisto -- With a diameter of over 4,800 km (2,985 miles), Callisto is the third largest satellite in the solar system and is almost the size of Mercury. Callisto is the outermost of the Galilean satellites, and orbits beyonds Jupiter's main radiation belts. It has the lowest density of the Galilean satellites (1.86 grams/cubic centimeter). Its interior is probably similar to Ganymede except the inner rocky core is smaller, and this core is surrounded by a large icy...

Jupiter's Moon Ganymede -- Ganymede is the largest satellite in the solar system with a diameter of 5,268 km (3270 miles). It is larger than Mercury and Pluto, and three-quarters the size of Mars. If Ganymede orbited the Sun instead of orbiting Jupiter, it would easily be classified as a planet. If Ganymede orbited the Sun instead of Jupiter it could be classified as a planet. Like Callisto, Ganymede is most likely composed of a rocky core with a water/ice mantle and a crust of rock and...
