'Eyes' of Herschel Will Survey Trans-Neptunian Region Paris, France (SPX) Oct 09, 2009 
In the framework of the key program "TNOs Are Cool: A Survey of the Trans-Neptunian Region," Herschel will reveal the physical properties of the poorly known objects orbiting beyond Neptune. The Herschel Space Observatory, one of the cornerstone missions of the European Space Agency with participation from NASA, was launched successfully in May this year. Herschel is the only space ... read moreAstronomy Question Of The Week: Why Is Pluto No Longer A Planet 
Bonn, Germany (SPX) Oct 06, 2009It happened on 24 August 2006: instead of the nine planets it had up to that time, our Solar System suddenly had only eight - the planet Pluto was no longer a planet. What happened? In August 2006, astronomers from all over the world gathered at the 26th General Assembly of the International Astronomical Union (IAU) in Prague. Among other things, they reorganised our planetary system and ... more

New Horizons Hits Halfway Mark Between Saturn, Uranus Orbits
Laurel MD (SPX) Sep 09, 2009New Horizons has sailed silently through another milestone on the way to its historic reconnaissance of the Pluto system, reaching the halfway point between the orbits of Saturn and Uranus. The NASA spacecraft will reach 14.41 astronomical units from the Sun - 1.34 billion miles, or nearly 14 1/2 times the distance between the Earth and Sun - between 6-7 p.m. EDT "Only five operating space ... more New Horizons Team Begins To Look At Kuiper Targets 
Boulder CO (SPX) Sep 04, 2009We put New Horizons back into hibernation last week, on Aug. 27. This event signaled the completion of our third active spacecraft and payload checkout, which occupied us for most of July and August. Active Checkout Three ("ACO-3") went very well, its objectives completed with no serious glitches. Our spacecraft and payload are healthy, on course and ready for a set of three hibernation ... more Dawn Continues Its Quiet Cruise 
Pasadena CA (SPX) Sep 02, 2009The Dawn mission remains on course as the spacecraft continues to thrust with its ion propulsion system, patiently, persistently, and gently changing its orbit to keep its appointment with protoplanet Vesta in two years. Meanwhile, closer to mission control and in stark contrast, brave firefighters work hard to protect JPL and the nearby homes of many of its employees and others in the community ... more New Horizons Checks Out, Enters Hibernation
Laurel MD (SPX) Sep 01, 2009The New Horizons mission team has closed out a successful summer workout, putting its Pluto-bound spacecraft back into hibernation on Aug. 27 after seven weeks of functional tests and system checks. The mission's third annual checkout (ACO-3), which started July 7, "went very well," says Mission System Engineer Chris Hersman, of the Johns Hopkins University Applied Physics Laboratory. "New ... more |

New Horizons Wakes For Annual Checkout
Baltimore MD (SPX) Jul 09, 2009New Horizons is up from the longest nap of its cruise to Pluto, as operators "woke" the spacecraft from hibernation yesterday for its annual series of checkouts and tests. The actual wake-up call went in months ago; the commands for New Horizons to power up and reawaken its hibernating systems were radioed to its computer before it entered hibernation on Dec. 16, 2008. During hibernation ... more Planning Six Years Ahead 
Laurel MD (SPX) May 22, 2009Things are going well out in the cold space between Saturn and Uranus where New Horizons is now. We're deep in planning for our spacecraft's annual checkout this summer, which begins on July 7. But that's not what I want to write about today: instead, it's something called EPDR. Despite still being more than six years and just over 18 astronomical units from the Pluto system, the New Horiz ... more New Horizons Team Remembers The Girl Who Named Pluto 
Laurel MD (SPX) May 12, 2009The team guiding the first mission to Pluto is fondly remembering Venetia Burney Phair, the "little girl" who named the ninth planet when it was discovered nearly 80 years ago. Mrs. Phair died April 30 at her home in Epsom, England, at age 90. "Venetia's interest and success in naming Pluto as a schoolgirl caught the attention of the world and earned her a place in the history of planetary ... more The PI's Perspective: One-Third Down 
Baltimore MD (SPX) Mar 20, 2009We passed the milestone of being one-third of the distance to Pluto last year, but on March 19, 2009 - after 38 months and almost 2 billion kilometers of flight, New Horizons has completed precisely one-third of the days in its journey to Pluto. That's quite a milestone, and we on the mission team celebrate the closing of this chapter of our historic journey across the great expanse of our ... more |
