New Explorer Mission Chooses The 'Goldilocks Orbit'
2013-08-01 08:05:06

NASA Principal Investigator George Ricker likes to call it the "Goldilocks orbit" -- it's not too close to Earth and her Moon, and it's not too far. In fact, it's just right. And as a result of this never-before-used orbit -- advanced and fine-tuned by NASA engineers and other members of the Transiting Exoplanet Survey Satellite (TESS) team -- the Explorer mission led by Ricker will be perfectly positioned to map the locations of more than 500 transiting exoplanets, extrasolar planets...

GALEX Space Telescope Decommissioned On Friday
2013-06-29 08:11:35

redOrbit Staff & Wire Reports - Your Universe Online After more than a decade of service, NASA officially decommissioned its Galaxy Evolution Explorer (GALEX) orbiting space telescope Friday afternoon. Operators at Virginia-based Orbital Sciences Corporation sent the signal to decommission GALEX at 3:09pm EDT (12:09pm PDT) on June 28. The telescope, which was launched into orbit on April 28, 2003, observed hundreds of millions of galaxies in ultraviolet light across 10 billion...

ESA Chooses Instruments For JUICE Mission
2013-02-21 10:11:35

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...

NuSTAR's Mirrors Baked In Zhang's Glass Kitchen
2012-02-24 04:28:37

It pays to persevere. No one knows this better than Will Zhang. For more than a decade, the astrophysicist at NASA's Goddard Space Flight Center in Greenbelt, Md., experimented with a new technique for efficiently manufacturing super-thin, low-cost curved telescope mirror segments to collect and focus ever-elusive, high-energy X-ray photons. The fruits of that labor -- a total of 9,000 individual mirror segments -- are now assembled into telescope optics and installed inside NASA's...

NASA has selected 11 science proposals for evaluation as potential future science missions. The proposals outline prospective missions to study the Earth's atmosphere, the sun, the Milky Way galaxy, and Earth-like planets around nearby stars. The selections were made from responses to Announcements of Opportunity for Explorer Missions and Explorer Missions of Opportunity released by the agency last November. The proposals were judged to have the best science value and feasible development...
