The International Space Station had to burn thrusters for more than 5 minutes on Monday night to avoid a chunk of debris from the satellite Russia shot down in November.

Space Station Maneuvers to Avoid Orbital Debris

This evening, the International Space Station’s Progress 81 thrusters fired for 5 minutes, 5 seconds in a Pre-Determined Debris Avoidance Maneuver (PDAM) to provide the complex an extra measure of distance away from the predicted track of a fragment of Russian Cosmos 1408 debris.

The thruster firing occurred at 8:25 p.m. EDT and the maneuver had no impact on station operations. Without the maneuver, it was predicted that the fragment could have passed within about three miles from the station.

The PDAM increased the station’s altitude by 2/10 of a mile at apogee and 8/10 of a mile at perigee and left the station in an orbit of 264.3 x 255.4 statute miles.

Another ISS collision avoidance burn; the debris culprit this time is probably object 51561  (1982-092BMN), a piece of Kosmos-1408 debris

51561 is in an elliptical 408 x 603 km orbit, and its perigee recently crossed the ISS orbital height range

Russia has developed a new technology for cleaning up space debris.

Samara scientists have developed a technology for efficient and safe removal of debris from orbit.

10:30 30.11.2022

SAMARA, November 30 - RIA Novosti. Samara University scientists have developed a technology to carry out a mission to efficiently and safely remove debris from orbit using a space cleaner, the press service of the university reports .

"Scientists from Samara University named after Korolev have developed a technology to carry out a mission to efficiently and safely remove space debris from orbit," the message says.

According to the press service, the technology is an improved technique for cleaning the orbit using a plasma torch - an ion stream created by the electric engine of the space cleaner. With this method of cleaning, the plasma "broom" of the space "janitor" sweeps space debris with a stream of ions in the right direction, sending it into the Earth's atmosphere for subsequent combustion in dense layers or moving it to a special disposal orbit - an orbital garbage landfill, the university specified.

The technology is described in the book "Space Dynamics and Control of Space Debris during Ion Flow Transport", published in November by Elsevier, one of the four largest scientific publishing houses in the world. The authors of the monograph are Professor, Head of the Department of Theoretical Mechanics of Samara University Vladimir Aslanov and Associate Professor of the Department of Theoretical Mechanics of the Institute of Rocket and Space Technology of the University Alexander Ledkov.

"Cleaning up old non-functioning satellites or spent rocket stages that remained in orbit after the payload was withdrawn is a multifaceted and complex scientific and technical task. To solve it, many schemes and methods have already been proposed in the world, including using ion flows, but missions to clean up space debris have not yet been carried out.Our monograph presents in detail the method of non-contact cleaning of debris in orbit using an automatic space cleaner equipped with ion engines, such engines are widely used in modern astronautics. distance of about ten meters, will send an ion jet of the engine, the so-called plasma torch, to it. Colliding with the surface of space debris,the particles of the ion jet generate a force that will be used to move the debris in the right direction," Ledkov was quoted as saying by the press service.

As the scientist noted, most of the methods developed in the world for cleaning up space debris involve direct contact - docking or capturing a transported object with a harpoon, net, cable or robotic arm. However, all these methods are quite complicated and dangerous, they can lead to an emergency collision and the appearance of a large amount of small space debris. The non-contact method is safer: the cleaning device does not come into direct mechanical contact with debris, which reduces the likelihood of their collision. In addition, in this way it is possible to transport rapidly rotating objects that are very difficult to capture with a robotic arm or a space network.​ ​ ​ ​

Russian satellites’ near-misses with space debris rise almost twofold — tech firm.

It is reported that the growth of the amount of debris in outer space leads to a larger number of dangerous situations with space vehicles.

12 DEC, 02:18

MOSCOW, December 12. /TASS/. Dangerous near-misses of Russian satellites and the International Space Station (ISS) with space debris reached about 70,000 instances in 2022 compared to over 40,000 in the previous year, Adviser to the CEO of TsNIImash Maksim Penkov said in an interview with the Vestnik Glonass journal published on Monday.

"The number of launches of space vehicles has grown considerably nowadays and this, naturally, has led to an increase in the amount of man-made space objects, including space debris," he said.

"The growth of the amount of debris in outer space leads to a larger number of dangerous situations with space vehicles. Over this year, about 70,000 dangerous near-misses of space vehicles of the Russian orbital cluster, including the International Space Station, with potentially dangerous man-made space objects have been registered. Throughout 2021, over 40,000 near-misses were registered," he said.
