ISS changes orbit to avoid collision with Chinese debris by Staff Writers Moscow (Sputnik) Nov 15, 2021
The station was hit by space debris earlier this year. A piece of space junk struck the Canadian remote robotic system, but the incident did not affect the operation of the device or the ISS in general. The International Space Station had to perform a manoeuvre in order to avoid a collision with space junk, left by the Chinese Fengyun-1C satellite, the Russian State Space Corporation Roscosmos reported. "The orbital altitude of the ISS was raised on Wednesday evening to avoid conjunction with space debris. According to preliminary data, the manoeuvre has raised the station's orbit by around 1.2 kilometres", the statement said. The Chinese satellite was destroyed in 2007 in an anti-satellite missile test. It exploded into more than 3,500 pieces of debris, most of which are still orbiting the planet. Source: RIA Novosti
Tiny grains, severe damage: Hypervelocity dust impacts on a spacecraft produce plasma explosions and debris clouds Pittsburgh PA (SPX) Nov 09, 2021 The Parker Solar Probe spacecraft, NASA's newest and most ambitious effort to study the sun, has broken a lot of records: it has gotten closer to the sun than any other spacecraft to date, its instruments have operated at the hottest temperatures, and the probe is the fastest human-made object ever. But those records come at a cost: The spacecraft is moving so fast that running into even a tiny grain of dust can lead to serious damage. New research by scientists at the Laboratory for Atmospheric a ... read more
