Researchers at Queen's University are developing a new robotic system to service more than 8,000 satellites now orbiting the Earth, beyond the flight range of ground-based repair operations. Currently, when the high-flying celestial objects malfunction "“ or simply run out of fuel "“ they become "space junk" cluttering the cosmos. "These are mechanical systems, which means that eventually they will fail," notes Electrical and Computer Engineering professor Michael Greenspan, who...

NASA announced on Monday that next month's shuttle flight to the Hubble Space Telescope faces an increased risk of getting hit by space junk because it will be in a higher, more littered orbit than usual. Because of the increased risk, managers at NASA's highest levels will need to sign off on the mission. The odds of a catastrophic strike by orbital debris including bits of space junk are at about 1-in-185 during Atlantis' upcoming mission to Hubble. That compares to 1-in-300 odds for a...

KOROLYOV, Moscow region. Aug 28 (Interfax-AVN) - Russian Mission Control has adjusted the orbit of the International Space Station (ISS) to prevent it from colliding with pieces of space junk. "The information on the possibility of a collision was obtained from the Russian and U.S. space-monitoring services," the Mission Control told Interfax. The ISS orbit was adjusted with the help of the European Jules Verne spacecraft. The ISS orbit was been lowered by about 2 km and is now 354 km...

EXTON, Pa., Aug. 4 /PRNewswire/ -- The Center for Space Standards & Innovation's SOCRATES-GEO service reached a milestone June 26 when the 100th GEO satellite was added to its system. CSSI, the research arm of Analytical Graphics, Inc. (AGI), provides Satellite Orbital Conjunction Reports Assessing Threatening Encounters in Space (SOCRATES), a service for satellite owner/operators that lists the top 10 pending potential satellite collisions each week. In early 2008, CSSI began offering...

Think you have trouble getting rid of the clutter in your living room? After more than 50 years of launching rockets and satellites into space, the human race now has to deal with the clutter left behind -- or is it "above"? Dead satellites, spent rocket stages, paint flakes, and coolant from nuclear-powered satellites continue to orbit the Earth at ultrahigh velocities. It's a serious subject. Space debris threatens the lives of astronauts and the launch of new satellites today, says Dr....

"Hold your hands out to the sun. What do you feel? Heat, of course. But there's pressure as well "“ though you've never noticed it, because it's so tiny. Over the area of your hands, it only comes to about a millionth of an ounce. But out in space, even a pressure as small as that can be important "“ for it's acting all the time, hour after hour, day after day. Unlike rocket fuel, it's free and unlimited. If we want to, we can use it; we can build sails to catch the radiation...

Not so long ago, anyone claiming to see flashes of light on the Moon would be viewed with deep suspicion by professional astronomers. Such reports were filed under "L" "¦ for lunatic. Not anymore. Over the past two and a half years, NASA astronomers have observed the Moon flashing at them not just once but one hundred times. "They're explosions caused by meteoroids hitting the Moon," explains Bill Cooke, head of NASA's Meteoroid Environment Office at the Marshall Space Flight Center...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
