Orbital Debris What is orbital debris? Orbital debris is any man-made object in orbit about Earth which no longer serves a useful purpose. What are examples of orbital debris? Derelict spacecraft and upper stages of launch vehicles, carriers for multiple payloads, debris intentionally released during spacecraft separation from its launch vehicle or during mission operations, debris created as a result of spacecraft or upper stage explosions or collisions, solid rocket motor effluents, and tiny flecks of paint released by thermal stress or small particle impacts.
In the first crash of its kind, two communication satellites collided on February 10, in orbit shooting out a pair of huge debris clouds and poising a slight risk to the International Space Station ISS.
The collision occurred nearly km over Siberia and involved a US Iridium commercial satellite launched in and a defunct Russian satellite Cosmos launched in Iridium satellite weighed kg, while the Russian craft nearly a tonne.
The incident raised questions over how it was allowed to happen and what will become of the cloud of orbital debris, which adds to one of the biggest headaches in space.
Orbital debris essays collision has fuelled concerns over lack of traffic controls in space and the rising volumes of junk that endanger vital satellites and manned flights. Just a month after the Iridium accident, a stray motor chunk hurtled toward the International Space Station.
It would give them a chance to abandon ship, if necessary. After a few minutes, the motor zipped by, missing the ISS by just a few miles in space terms, a close call. Then on December 1,with almost no warning, a small chunk from a different Cosmos satellite hurtled toward the ISS, coming within a mile of a direct hit.
Due to its speeding-bullet velocity, even this fragment could have had an impact equal to a truck bomb and would have blown everything to smithereens.
Incidents like these serve as clear signs that something must finally be done about space junk. Its proliferation threatens not only current and future space missions but also global communications mobile phone networks, satellite television, radio broadcasts, weather tracking, and military surveillance, even the dashboard GPS devices that keep us from getting lost.
The number of manufactured objects cluttering the sky is now expected to double every few years as large objects weaken and split apart and new collisions create more Kesslerian debris, leading to yet more collisions.

If we look at a brief history of space junk, the Telstar-1 satellite which relayed the first phone calls and TV signals across the Atlantic is still in the space after failing in Bythe number of catalogued orbiting debris objects of over 10cm in diameter had reached nearly 6, Bythese increased to 10, Ina Chinese test weapon shot down the Fengyun-1C satellite, creating some 3, new pieces of trackable space junk.
At present, the number of catalogued debris objects has crossed the 15, mark. Space debris comprises the ever increasing amount of inactive space hardware in orbit around the earth as well as fragments of spacecraft that have broken up exploded or otherwise become abandoned. About 50 per cent of all trackable objects are due to in-orbit explosion events about or collision events less than Litter in orbit has increased in recent years, in part because of the deliberate break-ups of old satellites.
It has become so bad that orbital debris is now the biggest threat to space shuttle in flight, surpassing the dangers of lift-off and return to Earth. Between the launch of Sputnik on 4 October and 1 Januaryapproximately launches have placed some satellites in to orbit, of which about are travelling beyond geostationary orbit or on interplanetary trajectories.
China added significantly to space debris when it used a ground based ballistic missile to blow apart an obsolete weather satellite in a January arms test. The United States used a missile from a Navy warship to explode a tank of toxic fuel on crippled US spy satellite in February Currently, the US Space Surveillance Network is using ground- based radar, optical and infrared sensors to track more than objects.
Only about 6 per cent of these catalogued objects are active satellites.Orbital Debris Orbital Debris is an unknown problem in the world. Most people don't know that there are thousands upon thousands of pieces of junk in the atmosphere.
People don't know that having the junk in the atmosphere is very dangerous for satellites, the earth and future space launche. Space debris is also referred to as space junk, space waste, orbital junk, orbital debris, and space trash.
Space junk consists of nonfunctional satellites, old pieces of spacecraft, bits and pieces of booster rockets, lost equipment, and other pieces of garbage.

FM Reading Response 1: Dave Gilbert’s “Space Harpoon Plan to Nail Orbital Garbage” Summary The article Space Harpoon Plan to Nail Orbital Garbage talks about this invention called a “space harpoon” that will eliminate only some of the space debris that is in earth’s low orbit.
Space debris can be categorized into two different groups which consist of both natural and artificial particles.
Natural particles- meteoroids can be found only in orbit about the sun . It is the opposite for artificial particles where these particles are only tracked within the orbits of earth.
