On Thursday, a top U.S. general called for international rules to control chaotic space traffic, saying that satellites are increasingly being put at risk of collision. General James Cartwright, vice chairman of the Joint Chiefs of Staff, said it was no longer feasible for the U.S. and other countries to keep up with the orbiting satellites if kept a secret. "We're going to have get to some level of regulation. Nobody wants to do that," Cartwright told a conference sponsored by the Center...

You know them as "shooting stars," or meteors. Space scientists know them as the fiery end of tiny visitors from space. Those momentary streaks of light across the night sky are nothing more than small to almost-microscopic pieces of space debris whose trip through the void has ended in a kamikaze run into Earth's atmosphere. Of course, with 100 tons of space rock and rubble bombarding the planet each and every day, you'd think you could stick your head out the window any night of the week...

The major powers of the world are being called upon to clean up space "litter" that is becoming increasingly dangerous for spacecraft, the head of the U.S. Strategic Command said on Wednesday. According to Reuters, former astronaut and Air Force General Kevin Chilton told an Israeli audience that the U.S. has documented more than 15,000 items, including jettisoned rockets, shuttle detritus, and pieces of destroyed satellites floating in space, reported Reuters. "The estimation is that these...

The U.S. space agency says it will not be necessary to move space shuttle Discovery and the International Space Station to avoid reported space debris. Astronauts aboard space shuttle Discovery, docked at the International Space Station, were awakened at 12:30 p.m. EDT Thursday with the song There is a God. Aside the song, performed by 33 Miles and played for astronaut Patrick Forrester, controllers at mission control in Houston told the crew the decision involving a possible debris avoidance...

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...
