NASA astronauts prepared Thursday for another spacewalk despite reports of space debris moving toward the International Space Station. NASA said astronauts Danny Olivas and Christer Fuglesang spent their sleep period inside an ISS airlock in preparation for the second STS-128 spacewalk, scheduled to begin at 5:19 p.m. EDT Thursday. John McCullough, NASA flight director, said it did not appear likely the docked space shuttle Discovery would have to fire its thrusters to move it and the space...

Earth observation satellites in low orbit are continually buffeted by the wisps of atmosphere that remain. Predicting how much air drag a satellite can encounter is critical to the design, cost and operation of a mission "“ an ESA study shows how. Earth's atmosphere is often portrayed as a fragile, finite, thin layer of gas blanketing the planet. However, since the number of atmospheric particles decrease exponentially with altitude, there is no real boundary between the atmosphere and...

Crewmembers aboard space shuttle Atlantis continued their pursuit of the Hubble Telescope on Wednesday as they prepare to make contact with the observatory for the first time since March 2002. Shuttle commander Scott Altman will guide Atlantis close enough to Hubble so that astronaut Megan McArthur can grab it with the shuttle's robotic arm and lift it to the shuttle's cargo bay where astronauts will make a series of crucial repairs in the final upgrade mission to the telescope. Repairs and...

With space becoming increasingly more crowded, scientists are turning to "sails" to help satellites and other orbiting space objects return more rapidly to Earth.  Researchers hope the approach will help minimize the number of redundant objects in orbit, thereby reducing collision threats to operational missions. Extending a sail on an old spacecraft would increase its drag, pulling the vehicle back in to the Earth's atmosphere to burn up. It's a concept with great potential, said...

ARLINGTON, Va., April 28 /PRNewswire-USNewswire/ -- Space debris is a current and growing threat to U.S. exploration activities, and leaders must make situational awareness a top national priority, AIA President and CEO Marion Blakey said in congressional testimony Tuesday. In written testimony submitted to the House Space and Aeronautics Subcommittee, Blakey detailed the challenges created by tens of thousands of man-made objects orbiting the Earth. These items, which include both...

During the Space Foundation's National Space Symposium, the US Air Force announced it would be working alongside US Strategic Command to develop a better system of tracking objects in space.The Air Force said it hopes to improve satellite tracking to cover all 800 maneuverable spacecraft by October 8.The push for better tracking comes in light of the recent collision between a defunct Russian and US satellite on February 10. US military and private tracking groups were unable to forecast the...

In response to more reports of dangerous space junk, the European Space Agency (ESA) on Thursday announced plans to begin a monitoring system for orbital space debris within the next few years."The goal is to be able to offer 'precursor' services in the next two or three years which among other things issue alerts about collision risks," Nicolas Bobrinsky of ESA's European Space Operations Centre in Darmstadt, told AFP."We already have the installations and a knowledge base which we have to...

The European Space Agency is the host for the Fifth European Conference on Space Debris through Thursday at its Space Operations Center in Darmstadt, Germany. The ESA said the conference, which began Monday, is the largest dedicated event on space debris issues. It is co-sponsored by the British, French, German and Italian space agencies, the Committee on Space Research and the International Academy of Astronautics. Space debris has recently been attracting increasing attention not only due...

The U.S. space agency says the International Space Station was briefly evacuated Thursday when space debris was detected heading toward it. National Aeronautics and Space Administration controllers in Houston ordered the ISS crew to enter a safety capsule until the debris had passed. The crew was notified of the all clear at 12:45 p.m. EDT, NASA said in a brief statement, noting the crew then left the Soyuz safety capsule and returned the station to normal operations. Had the debris struck...

International Space Station Expedition 18 crew members had to take precautionary measures due to space debris that had been determined to be within the range where a collision was possible. News of the close approach came too late for flight controllers to coordinate an avoidance maneuver. A portion of a spent satellite motor was within the distance of the station's debris avoidance maneuver requirement "box." Crew members entered their Soyuz TMA-13 capsule and soft-locked the hatches,...

Word of the Day
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
