redOrbit Staff & Wire Reports - Your Universe Online Researchers from the Lawrence Livermore National Laboratory (LLNL) in California have developed and tested a series of ground-based mini-satellites that will be used to help control traffic in space. These so-called “space cops” were used by the LLNL team to capture a series of six images over a 60-hour period to prove that they can be used to alter the orbit of other probes traveling in low-earth orbit. The plan is to use the...

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...

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...

MESSENGER successfully completed an orbit-correction maneuver on March 2 to lower its periapsis altitude - the lowest point of MESSENGER's orbit about Mercury relative to the planet's surface - from 405 to 200 kilometers (251 to 124 miles). This is the first of three planned maneuvers designed to modify the spacecraft's orbit around Mercury as science operations transition from MESSENGER's primary orbital mission to its extended mission. MESSENGER's orbit around Mercury is highly...

NASA Called Upon to Create Plan For Dealing With Space Junk
2011-09-02 04:18:43

  While NASA has "responsibly" used its resources in detecting meteoroids and orbital debris, the growing amount of space junk and the danger it poses to the crew of the International Space Station (ISS) requires additional funding for the U.S. space agency's detection and monitoring efforts, the National Research Council says in a new report. According to an article by AP Science Writer Seth Borenstein, officials involved with the report, which was commissioned by NASA, claim that...

The MESSENGER spacecraft continued to fine-tune its orbit around Mercury yesterday afternoon when mission controllers at the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., successfully executed the second orbit-correction maneuver of the mission. The 3-minute, 8-second engine burn stretched the spacecraft's orbit around the innermost planet from 11 hours 48 minutes to a precise 12 hours. This second of an expected five maneuvers planned for the mission's primary...

A Pentagon report warned that space is so littered with debris that a collision between satellites could set off an "uncontrolled chain reaction" capable of destroying the communications network on Earth. Scientists said that the volume of abandoned rockets, shattered satellites and missile shrapnel in Earth's orbit is reaching a "tipping point" and is now threatening the $250 billion space services industry. The report said that a collision between two satellites or large pieces of space...

Global Aerospace Corporation (GAC) announced recently that Dr. Kristin L. Gates will present a paper on de-orbiting space junk at the August 2 Artificial and Natural Space Debris session of the AIAA Astrodynamics Specialists Conference in Toronto, Ontario, Canada. Dr. Gates will describe GAC's Gossamer Orbit Lowering Device (GOLD) for safe and efficient removal from Low Earth Orbit (LEO) of dangerous space objects. The patented GOLD system concept uses a very large ultra thin balloon envelope...

The head of the Pentagon's Strategic Command said on Friday that no debris remains in space after last year's U.S. destruction of an errant spy satellite loaded with toxic hydrazine fuel, Reuters reported. Air Force Gen. Kevin Chilton, the command's chief, said some of the debris caused when China used a ground-based ballistic missile to destroy one of its defunct weather satellites will stay in orbit for another 80 or 90 years, so there was no reason for concern over the U.S. operation....

Two satellites collided in orbit on Tuesday, prompting NASA to announce it to be the first collision of its kind in space. A US commercially-owned satellite collided with a crippled Russian military satellite in low-earth orbit. The commercial satellite was owned by Bethseda, Maryland-based Iridium Satellite LLC, which characterized the event as "extremely unusual." However, "the Iridium constellation is uniquely designed to withstand such an event, and the company is taking the necessary...

Orbit -- An orbit is the path that an object makes around another object under the influence of some force. The classical example is that of the solar system, where the Earth, other planets, asteroids, comets, and smaller pieces of rubble are in orbit around the Sun; and moons are in orbit around planets. These days, many artificial satellites are in orbit around the Earth. Understanding orbits There are a few common ways of understanding orbits. -- As the object moves, it...
