ESA Cluster Satellites Achieve Closest-Ever Approach Thursday
2013-09-21 07:39:16

redOrbit Staff & Wire Reports – Your Universe Online The close approach of two of the European Space Agency’s (ESA) four identical Cluster satellites this week provided researchers with a rare opportunity to collect valuable information with unprecedented detail. According to a statement released by the organization on Friday, a pair of the probes achieved their closest-ever separation on September 19. The satellites, which have been probing the Earth’s magnetosphere in three...

Europa Surface Cracks Associated With One-Time Tilted Axis
2013-09-18 15:05:45

[ Watch the Video: Jupiter Moon's Cracks Due To Tilted Axis ] Lee Rannals for redOrbit.com - Your Universe Online New evidence shows that Jupiter's moon Europa most likely was once spinning around on a tilted axis. NASA scientists analyzed distinctive cracks lining the surface of Europa and found that the moon used to have a small tilt in its spin axis. This information could influence calculations of how much of the moon's history is recorded in its frozen shell, how much heat is...

Amateur Astronomers See Fireballs Collide With Jupiter
2013-09-15 04:40:06

[ Watch the Video: Fireballs Collide With Jupiter’s Atmosphere ] redOrbit Staff & Wire Reports - Your Universe Online Amateur astronomers observing Jupiter with video cameras for the past three years have observed a trio of collisions between small stellar objects occurring around the planet, according to research presented last week at the European Planetary Science Congress (EPSC 2013) in London. The collisions are similar but smaller in scale than the meteor explosion that...

Several Key Discoveries During Van Allen Probes’ First Year
2013-09-01 07:49:38

redOrbit Staff & Wire Reports – Your Universe Online NASA’s twin Van Allen Probes entered their second year of service Friday having already provided a wealth of new information about the layers of energetic charged particles located above our planet. According to the US space agency, data collected by the probes since their August 30, 2012 launch has already led to “several significant discoveries” about the Van Allen radiation belts -- some of which came within the first...

Fukushima Plume To Be Harmless By The Time It Reaches US Shores In 2014
2013-08-29 04:02:04

redOrbit Staff & Wire Reports - Your Universe Online The radioactive ocean plume created as a result of the 2011 Fukushima nuclear power plant disaster is expected to reach North America by next year, according to research appearing in the latest edition of the journal Deep-Sea Research 1. Fortunately, the study authors report the plume will be harmless by the time it reaches US shores. “Observers on the west coast of the United States will be able to see a measurable increase...

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...
