Latest Geocentric orbit Stories
Researchers from the Lawrence Livermore National Laboratory in California have developed and tested a series of ground-based mini-satellites that will be used to help control traffic in space.
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.
An article coming out in the Journal of Spacecraft and Rockets pitches ideas to attempt to remove orbital debris with less risk.
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).
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 requires additional funding for the U.S. space agency's detection and monitoring efforts.
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.
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.
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.
The head of the Pentagon's Strategic Command said on Friday that no debris remains in space after last yearâ€™s US destruction of an errant spy satellite loaded with toxic hydrazine fuel.
Two satellites collided in orbit on Tuesday, prompting NASA to announce it to be the first collision of its kind in space.
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...
