April Flowers for redOrbit.com - Your Universe Online With hundreds of volcanoes, some erupting lava fountains up to 250 miles high, Jupiter's moon Io is the most volcanically active world in our Solar System. According to NASA and European Space Agency (ESA) researchers, though, concentrations of volcanic activity are significantly displaced from where they are expected to be based on models used to predict how the moon's interior is heated. The team, which included scientists from...
WASHINGTON, Feb. 21, 2013 /PRNewswire-USNewswire/ -- NASA has selected key contributions to a 2022 European Space Agency (ESA) mission that will study Jupiter and three of its largest moons in unprecedented detail. The moons are thought to harbor vast water oceans beneath their icy surfaces. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO ) NASA's contribution will consist of one U.S.-led science instrument and hardware for two European instruments to fly on ESA's...
ESA The JUpiter ICy moons Explorer mission, JUICE, will carry a total of 11 scientific experiments to study the gas giant planet and its large ocean-bearing moons, ESA announced today. JUICE is the first Large-class mission in ESA's Cosmic Vision 2015-2025 program. Planned for launch in 2022 and arrival at Jupiter in 2030, it will spend at least three years making detailed observations of the biggest planet in the Solar System and three of its largest moons, Ganymede, Callisto and...
Lee Rannals for redOrbit.com – Your Universe Online New research based on observations from NASA's Cassini spacecraft show that Titan, Saturn's largest moon, may look younger than it really is. While most moons display their age through their thousands of craters, NASA said that Titan's craters are being erased, giving it a 'Benjamin Button' appearance. "Most of the Saturnian satellites - Titan's siblings - have thousands and thousands of craters on their surface. So far on Titan,...
VIRGINIA BEACH, Va., Nov. 8, 2012 /PRNewswire/ -- An international terrorist plot unfolds as three competing forces collide. Readers are immersed in a deeply powerful plot that invites them to view the action from three different perspectives, influenced by the loyalties, commitment, and resources of each. This debut novel of intrigue, international terrorism, and covert missions, by author Terrence Douglas, depicts strong characters that introduce Ganymede. "The murder of German...
Lee Rannals for redOrbit.com - Your Universe Online Astronomers reported at the European Planetary Science Congress that they have produced the first amateur albedo map of Jupiter's moon Ganymede. This map shows off the higher areas of reflectivity on an object's surface, recording where material is bright or darker in areas. The map developed by the astronomers closely aligns with professional images of Ganymede's surface, showing off features like Phrygia Sulcus and the Nicholson...
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...
Lee Rannals for RedOrbit.com The European Space Agency (ESA) has selected a Jupiter probe to be its next "large class" space endeavor after a five-year-long competition. The JUpiter Icy moon Explorer (JUICE) has been approved at a meeting of member state delegations in Paris. The probe would be built in time for launch in 2022, and will take eight years to reach the Jovian system. JUICE is a nearly five-ton satellite that aims to orbit Jupiter's moon Ganymede, as well as make...
The Jupiter Icy Moon Explorer (JUICE) proposal to study the moons of Jupiter is leading the pack of proposed missions. The mission would launch in 2022 to study Jupiter's moons and determine whether any of them are capable of supporting life. JUICE, according to BBC News, is waiting for a European space committee to meet and discuss the mission, along with other contenders, in May. The spacecraft in the mission would study three of Jupiter's Galilean moons, using gravity of the large...
A team of scientists led by Arizona State University has produced the first complete geologic map of Jupiter’s moon, Io. Published by the US Geological Survey, the new map reveals geologically unique features, volcanoes, and lava flows as well as some relative ages of the moon. Galileo first discovered Io more than 400 years ago. Io is the largest and innermost moon to orbit the planet Jupiter and has been the subject of many scientific studies as well as intense observation. Existing...

Aquila (the Eagle) Constellation -- Location: Northern Hemisphere; Coordinates: Right Ascension: 20h; Declination: 05; Source: Various cultures - Greek, Arab, Persian, Indian, Japanese, Chinese, Korean The story behind the name In the ancient Middle Eastern and Mediterranean cultures, the constellation Aquila is seen as the shape of a flying bird. The pattern contains three prominent stars that can be seen to outline the wings of a bird, but are also the focus of quite different myths...
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...
Jupiter's Moon Europa -- Europa is a puzzle. The sixth largest moon in our Solar System, Europa confounds and intrigues scientists. Few bodies in the Solar System have attracted as much scientific attention as this moon of Jupiter because of its possible subsurface ocean of water. The more we learn about this icy moon, the more questions we have. Because the nature of science is to ask questions, we cannot resist the mystery of Europa and its potential for possessing an ocean. Early...
Jupiter's Moon Io -- Looking like a giant pizza covered with melted cheese and splotches of tomato and ripe olives, Io is the most volcanically active body in the solar system. Volcanic plumes rise 300 kilometers (190 miles) above the surface, with material spewing out at nearly half the required escape velocity. A bit larger than Earth's moon, Io is the third largest of Jupiter's moons, and the fifth one in distance from the planet. Although Io always points the same side toward...
