Russian space officials on Wednesday acknowledged a continuing air leak from the Russian segment of the International Space Station, but said it poses no danger to its crew.

In recent years, with the significant increase in space launch activities, the number of deorbited spacecraft has sharply risen, posing a serious impact on both active orbiting spacecraft and future space activities. Traditional rope net capture systems, serving as a technology for actively deorbiting spacecraft, hold vast potential in mitigating and clearing space debris.

However, rope systems face challenges such as difficulty in maintaining shape over extended periods, susceptibility to self-entanglement, energy losses, and a reduction in the effective capture area. In contrast, thin films can fold and unfold along regular shapes, offering greater flexibility and reliability compared to tethers. They emerge as an effective solution to the entanglement issue and present a promising method for space debris mitigation and removal.

In a review article recently published in Space: Science & Technology, Professor Wei Cheng's team at Harbin Institute of Technology, in collaboration with researchers from Beijing Institute of Control Engineering and Benha University, has designed a thin film capture pocket system.
