[ Watch the Video: Voyager 1 at the Final Frontier ] redOrbit Staff & Wire Reports - Your Universe Online The levels of high-energy cosmic rays originating from outside our solar system and the levels of lower-energy particles originating from within have been undergoing changes at a faster rate than at any other time in the past seven years, NASA officials announced on Friday. Citing data obtained from the Voyager 1 spacecraft, the US space agency revealed that there was a...
April Flowers for redOrbit.com - Your Universe Online The Universe is filled with plasma, a charged gas consisting of ions and electrons. Thin sheets, or boundaries, with currents separate large plasma regions. These boundaries are where most of the exciting action in space happens. Scientists at the Swedish Institute of Space Physics (IRF) have measured the fundamental properties of one of the waves mixing and accelerating plasmas within these sheets. These thin current sheets are...
April Flowers for redOrbit.com - Your Universe Online People say things will happen "once in a blue moon" when they mean it's unlikely to happen or something very rare. In fact, we've been using a "blue moon" as synonymous with "never" for about 400 years. But what is a blue moon, really? A full moon that actually appears blue is very rare. It happens because of ash or dust in the air, sometimes from volcanic eruptions or major forest fires, which act like a color filter for your eyes...
Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency (ESA) announced on Tuesday that it has retired its GIOVE-B experimental navigation satellite. The satellite initiated a thruster firing yesterday, raising GIOVE-B's orbit by about 18 miles, taking it steps closer to a satellite graveyard up in orbit. More thruster firings will take place in the next three weeks, so that by mid-August the experimental satellite will be 372 miles above its original orbit....
Lee Rannals for redOrbit.com - Your Universe Online The Russian space agency is considering participating in a developing project to send a spacecraft to Jupiter. The European Space Agency (ESA) is starting-up the Jupiter Icy Moon Explorer (JUICE) project, and Russian scientists are considering the possibility of participating, according to a Voice Of Russia report. Lee Fletcher from JUICE’s Oxford University scientific group presented the objectives of the mission at the...
Brett Smith for redOrbit.com - Your Universe Online In addition to being fairly unpredictable, volcanoes can eject a wide range of material, from mile-high plums of black ash to a deadly hail of fist-sized pumice. These ejections travel extremely fast and can reach internal temperatures between 750 to 1,500 degrees Fahrenheit. The prevailing theory has been that the difference in particle size determined when bubbling magma deep below the volcano converts into a rising stream of gas and...
PHOENIX, July 24, 2012 /PRNewswire/ -- IO, the leading provider of next-generation modular data center technology and services, today announced the company has been awarded a contract by BEX Express, a managed services provider for small and medium-sized companies. IO will provide BEX Express with Data Center as a Service (DCaaS(TM)) delivered out of the IO Phoenix data center. This approach supplies BEX Express a high-performance, cost-effective solution - without having to invest...
[ Watch the Video ] redOrbit Staff & Wire Reports - Your Universe Online In what can be described as a melding of astronomy and post-Impressionist art, one NASA solar scientist has developed a new technique that uses bright, bold colors to share information about the heating and cooling of various parts of the sun. Nicholeen Viall of the NASA Goddard Space Flight Center in Greenbelt, Maryland innovated this new method, which uses various hues splashed across a yellow background...
[ Watch the Video ] Lee Rannals for redOrbit.com - Your Universe Online A new NASA mission set to launch in August 2012 called the Radiation Belt Storm Probes (RBSP) will keep its eye focused on plasma. Ninety-nine percent of the universe is made of this electrified gas, but when it comes to the Earth it is more absent than present. There are two giant donuts of plasma surrounding Earth trapped within a region known as the Van Allen Radiation Belts. The belts are close to...
Latest Io Reference Libraries
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...
