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,...

Deep Sea Trash
2013-06-06 11:39:00

Brett Smith for redOrbit.com - Your Universe Online For years, people have known about the amount of human-generated trash that ends up in the ocean, but a new study in the journal Deep-Sea Research I: Oceanographic Research Papers showed just how deep our detritus sinks, particularly in the waters around Monterey, California. "We were inspired by a fisheries study off Southern California that looked at seafloor trash down to 365 meters,” said lead author Kyra Schlining, a senior...

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,...

Floating plastic debris – which helps populate the infamous "Great Pacific Garbage Patch" in the Pacific Ocean – has become a problem in the Great Lakes, the largest body of fresh water in the world. Scientists reported on the latest findings from the Great Lakes here today at the 245th National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society. "The massive production of plastic and inadequate disposal has made plastic...

How To Remove Orbital Debris With Less Risk
2013-03-22 20:53:40

Lee Rannals for redOrbit.com — Your Universe Online An article coming out in the Journal of Spacecraft and Rockets pitches ideas to attempt to remove orbital debris with less risk. The article, authored by Kerry Nock and Dr. Kim Aaron, of Global Aerospace Corporation (GAC), and Dr. Darren McKnight, of Integrity Applications Incorporated, Chantilly, VA, compared in-orbit debris removal options regarding their potential risk of creating new orbital debris or disabling working...

Scientists Raise Concerns Over Tsunami Debris Carrying Invasive Species
2013-03-10 08:25:22

redOrbit Staff & Wire Reports - Your Universe Online Two years after the earthquake and tsunami that devastated Japan, researchers in the US and Canada are concerned about the possible damage that could be caused by invasive species that have found their way to North America on debris resulting from the 2011 disaster. According to UPI, experts in the northwest US and Canada are having difficulty determining whether or not marine life washing ashore on the debris will be a threat to...

Climate Change May Impact Satellites
2012-11-12 13:56:44

Lee Rannals for redOrbit.com — Your Universe Online Scientists wrote in the journal Nature Geoscience that rising carbon dioxide (CO2) levels could increase the accumulation of space junk. And as CO2 builds up in the upper levels of Earth's atmosphere it could have a significant effect on satellites in orbit. CO2 cools down the atmosphere and contracts its outermost layer, the thermosphere, which is where satellites and the International Space Station (ISS) operate. A...

Tackling The Problem Of Space Junk
2012-11-09 11:40:50

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online In late 2011 the National Research Council released a report stating that the amount of “space junk” orbiting the Earth had reached a tipping point. Since the 1960s, as the United States and others began launching satellites and rockets into space, the region known as Low Earth Orbit (LEO) has become increasingly crowded. The problem has become so significant that, when the Space Shuttle fleet was still...
