Space Debris Threat From Envisat Explored By University Of Leicester Students
2014-02-20 07:32:18

redOrbit Staff & Wire Reports - Your Universe Online A recently-published paper from physics students at the University of Leicester explores the possibility that a massive observational satellite that lost contact with Earth in 2012 could be the catalyst that sets off a chain of events much like those depicted in the Academy Award-nominated film Gravity. Writing in the Journal of Physics Special Topics, a peer-reviewed student journal run by the University’s Department of Physics...

Soviet-era Spy Satellite Burns Up Harmlessly In Earth's Atmosphere
2014-02-17 05:57:42

Lawrence LeBlond for redOrbit.com - Your Universe Online Fragments of a Soviet-era spy satellite, which was expected to crash back to Earth, had instead burned up on reentry into the atmosphere on Sunday. Colonel Dmitry Zenin, a spokesman for the Russian Defense Ministry, told Itar-Tass news agency that Kosmos-1220, a military signal intelligence satellite, reentered Earth’s atmosphere and burned up at about 5:58 p.m. local time (8:58 a.m. EST). The satellite, which had been in...

Using Talk Radio To Track Space Debris
2013-12-02 12:42:54

[ Watch the Video: Listening Up For Space Debris ] Lee Rannals for redOrbit.com - Your Universe Online Top-40 mixes being played over the FM airwaves are helping scientists locate space junk orbiting around our planet. Australian astronomers are using pop songs, talk radio and the Murchison Widefield Array (MWA) to help prevent catastrophic space junk collisions. As radio waves bounce around, they deflect off thousands of objects orbiting the Earth, which the team is able to take...

Protecting Earth From Asteroids Using Stardust
2013-11-18 17:41:17

Lee Rannals for redOrbit.com – Your Universe Online A new research program is bringing experts together to help protect our planet from asteroids that could become catastrophes. The Stardust program is the first research-based training network of its kind, bringing together some of the world’s best experts on asteroids and space debris. An open training school is being held at the University of Strathclyde this week in the first step to train the next generation of scientists,...

Using Space Probes To Deflect Asteroids From Earth Trajectories
2013-10-23 14:17:04

[ Watch the Video: Space Probes Could One Day Help Deflect Asteroids ] Lee Rannals for redOrbit.com - Your Universe Online Scientists are conducting experiments to figure out how space probes could be used to deflect potentially hazardous asteroids. Researchers at Fraunhofer Institute for High-Speed Dynamics have begun initial experiments to verify the possibility of deflecting asteroids by impacting them with heavy masses at high speeds. They said the principle behind their research...

Threat Of Space Debris On Human Spacecraft
2013-09-28 08:25:22

NASA More than 500,000 pieces of debris, or “space junk,” are tracked as they orbit the Earth. They all travel at speeds up to 17,500 mph, fast enough for a relatively small piece of orbital debris to damage a satellite or a spacecraft. The rising population of space debris increases the potential danger to all space vehicles, but especially to the International Space Station, space shuttles and other spacecraft with humans aboard. NASA takes the threat of collisions with space...

European Conference Attendees Agree Action Needed On Space Debris
2013-04-25 15:36:38

Lee Rannals for redOrbit.com — Your Universe Online The findings from the 6th European Conference on Space Debris were released during a press briefing at the ESA's European Space Operations Center (ESOC) in Darmstadt, Germany. The conference included over 350 worldwide participants representing all the major national space agencies, industry, governments, academia and research institutes. “There is a wide and strong expert consensus on the pressing need to act now to...

Experts To Meet In Europe To Discuss Space Debris Issue
2013-04-18 14:14:48

Lee Rannals for redOrbit.com — Your Universe Online Hundreds of experts from all over the world will be meeting at Europe's largest-ever space debris forum next week to discuss the latest findings on the growing problem of space junk. Space debris not only poses problems to other satellites and spacecraft in orbit but it is also hazardous to astronauts aboard the International Space Station (ISS). Scientists believe there could be around 29,000 objects larger than 4 inches,...

Russian Satellite Nailed By Chinese Space Debris, Orbit Affected
2013-03-12 14:50:23

Brett Smith for redOrbit.com - Your Universe Online Besides ruining the appearance of a landscape, litterbugs contribute to unsanitary and unsafe conditions, resulting in many communities issuing steep fines for anyone caught tossing their trash where it doesn´t belong. A recent event involving a Russian satellite suggests that we may have to take our approach to litterbugs and apply it to outer space as well. According to a report from the Colorado-based Analytical Graphics,...

Chinese Probe Gets Up Close And Personal With Asteroid 4179 Toutatis
2012-12-17 08:38:30

[Watch Video: Surface Features of Asteroid Toutatis Revealed By Radar] Lawrence LeBlond for redOrbit.com - Your Universe Online An asteroid by the name of 4179 Toutatis passed close enough to Earth last week that China´s Chang´e-2 probe was able to fly by the object, named for the Celtic deity Teutates by Christian Pollas in 1989, and snap some photos. The asteroid reportedly passed within 2 miles of the probe before swinging back out in Jupiter´s neighborhood....
