The Asteroids Are Coming![]() This isn't just "buzz" to get you excited about a new movie coming; we really are being buzzed by asteroids and other NEOs (Near Earth Objects), and one day these conjunctions could become collisions! There are lots of NEOs out there orbiting the sun. Some, like comets, are less worrisome since they are composed primarily of ice and small, rocky particles that dissipate upon entering Earth ... more Magnesium Detected During Second Flyby Of Mercury ![]() NASA's MESSENGER spacecraft served up another curveball to a University of Colorado at Boulder team after a second flyby of the hot inner planet Oct. 6 detected magnesium - an element created inside exploding stars and which is found in many medicine cabinets on Earth - clumped in the tenuous atmosphere of the planet. Scientists had suspected magnesium would be present, but were surprised ... more European-Built Node 3 Starts Its Journey To The ISS ![]() The European-built Node 3 module for the International Space Station will be shipped to NASA's Kennedy Space Centre, Florida, on 17 May. The Node 3 connecting module, built by prime contractor Thales Alenia Space in Turin, Italy, is the last element of a barter agreement by which ESA supplied NASA with International Space Station (ISS) hardware, including the Cupola and two Node modules (N ... more Boeing Completes PDR For Tracking And Data Relay Satellite Series K-L ![]() Boeing has successfully completed the system-level Preliminary Design Review (PDR) for its Tracking and Data Relay Satellite system (TDRS) K-L program, an important design milestone as the program moves toward integration of the TDRS K satellite for NASA. The comprehensive five-day review was held in El Segundo in March and attended by NASA project, program and Headquarters officials. ... more NASA Goddard Space Flight Center Celebrates 50 Years Of Scientific Excellence ![]() On a clear March day in 1926, in the middle of a snow-covered field in Auburn, Mass., Dr. Robert Hutchings Goddard changed exploration forever. Launching from a modified music stand, Goddard's liquid fuel rocket lifted itself 41 feet into the winter sky, flew for two and a half seconds, and landed in the space age. Goddard's dream had become reality. To honor Goddard's achievement an ... more |

![]() ![]() The Planck spacecraft has been mated with the Ariane 5 ECA launcher on 23 April 2009. After the successful fuelling of the Planck spacecraft in the S5A building a week earlier, the spacecraft was transferred to the final assembly building (Batiment d'Assemblage Final, or BAF) in the evening on 22 April. There it has been integrated on top of the launcher rocket that will place both the Pla ... more Some planets may fall into their stars ![]() U.S. astronomers say some of the hundreds of planets that once orbited stars outside our solar system may have fallen into their stars and no longer exist. University of Washington astronomer Rory Barnes says recent computer modeling has provided the first evidence gravitational forces might pull a planet into its parent star. "When we look at the observed properties of extrasola ... more Spirit problems still baffle scientists ![]() U.S. space agency scientists say they have not yet solved the mysterious cause of several glitches in the Mars exploration rover Spirit. National Aeronautics and Space Administration engineers remotely drove Spirit Thursday for the first time since April 8 while investigating bouts of amnesia and other unusual behavior exhibited by the rover this month. Spirit has already operate ... more NASA to study antifungal drugs in space ![]() The U.S. space agency says it plans to launch a small satellite about the size of a loaf of bread to study how effectively drugs work in space. The National Aeronautics and Space Administration nanosatellite, known as PharmaSat, is a secondary payload aboard a U.S. Air Force four-stage Minotaur 1 rocket planned to be launched May 5. "PharmaSat weighs approximately 10 pounds," NAS ... more |

![]() ![]() Top NASA and contractor managers assessed the risks associated with the STS-125 mission to service NASA's Hubble Space Telescope during Thursday's executive-level Flight Readiness Review at NASA's Kennedy Space Center in Florida, and determined the shuttle's equipment, support systems and procedures are ready for flight. "We had a very thorough review today," said Bill Gerstenmaier associa ... more An Active Mercury ![]() A NASA spacecraft gliding over the surface of Mercury has revealed that the planet's atmosphere, magnetosphere, and its geological past display greater levels of activity than scientists first suspected. The probe also discovered a large impact basin named "Rembrandt" measuring about 430 miles in diameter - equal to the distance between Washington and Boston. These new findings and more ar ... more Mercury flyby unveiled active inner planet: studies ![]() The US space probe MESSENGER's second fly-by of the planet Mercury in October 2008 revealed the solar system's smallest planet to be far more active than previously thought, four studies said Thursday. The MESSENGER (MErcury Surface, Space ENvironment, GEochemistry and Ranging) probe's cameras took more than 1,200 images of the surface, including details of a mammoth well-preserved 692-kilom ... more Astronomer searches for precursors of life ![]() A University of Michigan astronomer says he will use the European Space Agency's Herschel Space Telescope to search for the precursors of life. Associate Professor Ted Bergin said many organic molecules that make up life on Earth have also been found in space. Bergin wants to study those chemical compounds to gain insights into how organic molecules form in space, and, possibly, how lif ... more
