How To Get Rid Of Space Junk

How To Get Rid Of Space Junk – The place, as the name suggests, is mostly empty However, since the launch of the first satellite in 1957, mankind has begun to populate Earth’s orbit with all manner of spacecraft. On the other hand, space was also increasingly littered with debris from failed or broken rocket stages and satellites. At around 30,000 km/h, even small objects can put a hole in your spacecraft. Therefore, space debris poses a real threat to both manned and unmanned spacecraft, which is why space agencies are increasing efforts to track, prevent, and dispose of it.

According to NASA’s Orbital Debris Program Office (ODPO), there are currently about 500,000 marble-sized pieces of debris in Earth’s orbit and about 100,000,000 objects 1 mm or larger. As shown in the figure, there are two main debris fields Although most debris is in low Earth orbit (LEO) <2000 km altitude, there is a ring of space debris in geostationary orbit (GEO) ~36,000 km altitude.

The Irony. Clearspace 1 Couldn’t Clean Up Space Debris Because Its Target Already Got Hit By Space Debris, Creating Even More Space Debris.

Space debris includes abandoned spacecraft such as the Vanguard I satellite, which has been in orbit for more than 60 years, holding the record for the oldest man-made object in space. Other culprits are rocket upper stages that have crashed or exploded, so these days they are usually “passed” leaving burning fuel behind.

In 2007, China was criticized for blowing up the Fengin-1C weather satellite during a missile test. Along with the 2009 accidental collision of the US communications satellite Iridium 33 and the failed Russian Cosmos 2251 satellite, these events are responsible for most of the debris currently in orbit.

To protect itself from micrometeorites and orbital debris (MMODs), the spacecraft uses so-called Whipple shields, which are separated layers of space. Upon impact, the outer layer of the projectile is destroyed, thereby spreading its kinetic energy over a larger area during flight. To avoid collisions with known large objects, spacecraft must sometimes perform evasive maneuvers.

For the ISS, if the probability of a collision is greater than 1/10,000, such a maneuver is given an average of once a year. In 2012, a record number of such transfers had to be made – four, which is always expensive due to the huge amount of fuel consumed. NASA space shuttles have often been hit by MM MMODs, but thankfully so far all catastrophic collisions have been limited to unmanned spacecraft. An example of this is the case of the French satellite Ceres, which was shot down by a part of the Ariane launch vehicle in 1996. And we’ve already talked about the Iridum-Cosmos fall

The U.s. Is Getting Serious About Space Junk

It is important to catalog and track all debris floating in orbit to prevent future accidents and worsen the space debris problem in the future. A comprehensive catalog of space debris is maintained by the US Space Surveillance Network (SSN). They currently have more than 22,000 man-made objects orbiting Earth that are 10 centimeters or larger.

Depending on their altitude, objects of sufficient size can be detected by ground-based radar and optical telescopes. Optical telescopes measure sunlight reflected from debris, and distances can be accurately determined using laser ranges. This method is based on measuring the propagation time of a short laser pulse emitted from the ground and reflected from the object This method has long been used to track retroreflector-equipped satellites Because diffuse reflection from space debris is much weaker, it is more difficult to measure So far, this technique can only be used at dusk, when the Earth’s laser station is in the dark, but the debris is illuminated by the sun. Thanks to advanced imaging techniques, Austrian scientists were able to double the observation window and use lasers to spot space debris during daylight hours.

NASA’s Long Exposure Facility (LDEF) has taught us a lot about space debris Originally, it was a goal that had been in space for nearly six years before the Space Shuttle Columbia lifted off in 1990. LDEF has conducted 57 separate science experiments to study the long-term effects of the space environment on various materials and electronics. and biological samples Due to the large surface area and long-term exposure, a large amount of statistical information was obtained by studying the Swiss cheese pattern formed on its surface as shown in Fig.

Since 2002, all major space agencies have followed some general recommendations to limit the growth of space debris. After a GEO spacecraft completes its mission, it must go into a high orbit Objects passing through the LEO region must be de-orbited or at least transferred to a reduced orbit.

Return to earth. However, at 800 km altitude this can take decades, while debris from orbits above 1000 km will typically orbit the Earth for a century or more. We add space junk faster than it drops In the long term, therefore, we should not only stop polluting space, but actively dispose of some of the space junk in orbit. Otherwise, the debris density may be large enough to cause a cascading effect, with the debris created by the collision being further impacted. This phenomenon is known as Kessler syndrome and is well explained by Donald Kessler himself in this video.

Plans for active space debris removal include Swiss startup ClearSpace’s ESA-funded ClearSpace-1 mission, scheduled for launch in 2025. ) earlier stages have been released into orbit from previous ESA missions Both spacecraft will then de-orbit and burn up in the atmosphere Ultimately, the goal is to create a “recovery vehicle” in space that can intercept multiple objects in one mission.

The same lasers used to track space debris can also be used to remove it There are several ideas for using high-power, ground-based or space-based laser systems to remove ∼–cm space debris in Earth orbit. The laser vaporizes the object and creates a beam that slows down the target to quickly penetrate the atmosphere.

After we infect Earth to a destructive level, it would be good to see what happens in space It would be a shame if the scientific advances made possible by space travel and communication technology were halted by Kessler syndrome. With future mega-constellations of satellites like the Starlink project, this risk cannot be completely avoided.

A demonstration mission to test the concept of cleaning up space debris took off from the Baikonur Cosmodrome in Kazakhstan on Monday morning. The mission, known as ELSA-d, will demonstrate technology that could help intercept space debris — the millions of pieces floating around Earth.

Space Junk Removal Is Not Going Smoothly

More than 8,000 metric tons of waste threatens to destroy the services Earth relies on to support life, including weather forecasting, telecommunications and GPS systems.

The spacecraft attaches to the dead satellites and tries to push them towards Earth to burn up in the atmosphere

ELSA-d, which stands for End-of-Life Services, will be operated by the Japanese company behind the mission, AstroScal, using a “service satellite” and a “client satellite,” according to Astronomical. Using magnetic docking technology, the operator will attempt a “rendezvous” with the client by acting as simulated space debris.

The mission, controlled from the UK, will carry out repeated capture and release processes over six months. The goal is to demonstrate the ability of a service satellite to track and anchor its target at various levels of complexity.

Space Debris Cleanup Missions Receives Green Light

Spacecraft are not designed to intercept dead satellites already in orbit, but are designed to intercept future satellites that will be launched with docking plates attached to them.

Space debris has been a growing problem over the years, as man-made objects such as old satellites and parts of spacecraft accumulate in low Earth orbit.
