Scientists have produced a new version of what is perhaps NASA's best view of Jupiter's ice-covered moon, Europa.
By analyzing data from the Cassini mission, NASA researchers have found that the color of Jupiter’s Great Red Spot is most likely the result of simple chemicals being broken apart by sunlight in the planet’s upper atmosphere.
NASA's MESSENGER spacecraft has provided the first optical images of ice and other frozen volatile materials within permanently shadowed craters near Mercury's north pole.

Analysis of a massive rectangular feature buried just below the lunar surface by NASA’s GRAIL spacecraft has revealed that the giant basin on the moon’s near side was likely created by ancient lava flows and not a massive asteroid collision.
NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft has obtained its first observations of the extended upper atmosphere surrounding Mars.

WASHINGTON, Sept. 8, 2014 /PRNewswire-USNewswire/ -- Scientists have found evidence of plate tectonics on Jupiter's moon Europa.
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 Leda -- Leda ("LEE duh") is the ninth of Jupiter's known satellites and the smallest. Discovered by C. Kowal Date of discovery 1974 Mass (kg) 5.68e+15 Mass (Earth = 1) 9.5047e-10 Equatorial radius (km) 8 Equatorial radius (Earth = 1) 1.2543e-03 Mean density (gm/cm^3) 2.7 Mean distance from Jupiter (km) 11,094,000 Rotational period (days) ? Orbital period (days) 238.72 Mean orbital velocity (km/sec) 3.38 Orbital eccentricity 0.1476 Orbital inclination (degrees)...
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...
