Clay Minerals Found On Europa
2013-12-11 15:38:16

Lee Rannals for redOrbit.com - Your Universe Online Jupiter’s icy moon Europa appears to have clay-type minerals on its surface, according to new data from NASA’s Galileo mission. Scientists at the American Geophysical Union meeting in San Francisco say they have identified clay-like minerals on Europa for the first time. This finding could also imply that Europa carries organic materials. "Organic materials, which are important building blocks for life, are often found in comets...

DARPA Is At Work Developing The Latest High-Tech Spy Satellite
2013-12-10 13:19:11

[ Watch the video: DARPA MOIRE Concept Video ] Lee Rannals for redOrbit.com - Your Universe Online DARPA says it has plans to develop an ultimate spy satellite capable of viewing 40 percent of the Earth’s surface at once. The Membrane Optical Imager for Real-Time Exploitation (MOIRE) space telescope will be launched as a tightly packed cluster of petals 20 feet in diameter, helping it stretch out to 68 feet across. It will record the Earth’s surface with high resolution imagery,...

Lunar Impact Crater Has A Diverse Subsurface Mineralogy
2013-12-10 05:53:55

redOrbit Staff & Wire Reports - Your Universe Online The presence of a diverse group of minerals in the largest lunar impact crater could help scientists gain new insight into the Moon’s interior, as well as the evolution of its crust and mantle, claims new research appearing online in Journal of Geophysical Research: Planets. Dan Moriarty, a graduate student from Brown University, and his colleagues analyzed data collected from the Moon Mineralogy Mapper instrument aboard India's...

Earth's Van Allen Belts Thrust Particles To Near The Speed Of Light
2013-12-04 14:38:49

Lee Rannals for redOrbit.com - Your Universe Online NASA’s twin Van Allen Probes have led to another new discovery of Earth’s mysterious radiation belts. Researchers used data from the NASA spacecraft to reveal that the high-energy particles populating the Van Allen radiation belts can be accelerated to nearly the speed of light. This finding comes on the heels of a related discovery showing similar particle acceleration but on a microscopic, rather than planetary, scale. “The...

Pioneer Jupiter 40th anniversary
2013-12-04 13:45:49

Lee Rannals for redOrbit.com - Your Universe Online Forty years ago, man’s perspective of what blanketed the night sky grew even more dense as Pioneer 10 made its closest approach to Jupiter. On December 4, 1973, NASA’s Pioneer 10 spacecraft sent back images of Jupiter as it passed by, showing images of the darkest and brightest sides of the planet. “The most dramatic moment was after closest approach and after the spacecraft was hidden behind Jupiter. Here, images gradually...

Europa's Subsurface Ocean Currents And Patterns Act As A Heat Transfer
2013-12-04 04:25:36

[ Watch the Video: Saturn's Moon Europa Has A Dynamic Subsurface Ocean ] April Flowers for redOrbit.com - Your Universe Online Researchers from The University of Texas at Austin's Institute for Geophysics (UTIG), the Georgia Institute of Technology, and the Max Planck Institute for Solar System Research have revealed that the subsurface ocean on Jupiter's moon Europa might have deep currents and circulation patterns. These currents and patterns have heat and energy transfers capable 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...

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...
