Satellites protection technology is improved by Tomsk scientists
Researchers from the Tomsk State University (TSU) have improved devices that protect satellites from impacts of small particles and space debris.
1.5-2 millimeter sized particles are a real threat to the satellites. Moving at a speed of about 8 kilometers per second particle can damage key details and disable the device, the University press service explained.
New design of protective blocks was created by order of Lavochkin Research and Production Association (Russian aerospace company) for the Spektr-UV space telescope. Usually, space vehicles are protected by screens and grids with a low weight. Its strength is not always sufficient. «Instead of traditional grids arranged in parallel we proposed corrugated, in which the cells have a certain angle of inclination», Yuri Khristenko, Professor of the TSU, told. Moving at an angle to the grid, the particles are destroyed by several collisions. According to the tests, carried out in the University, new grid destroys particles twice as much as traditional protective one.
An improved version of the grid will be installed on Spektr-UV to protect the fuel tanks. Its launch is planned in 2021. The space telescope capability, it is claimed, are comparable to those of the Hubble Space Telescope.
