A team from the Chinese Academy of Sciences and the University of Electronic Science and Technology of China has published a paper detailing an advanced net-based system for capturing orbital debris. The concept, described as one of the most sophisticated net designs to date, aims to tackle the growing problem of space junk using a lightweight membrane that can ensnare defunct satellites or fragments.
The proposed net-membrane leverages deployable structures and electrostatic attraction to engage with debris, offering a potentially scalable solution compared to earlier ideas like electric tethers or lasers. The design targets objects in low Earth orbit, where collision risks are highest, though the paper does not specify exact material specifications or deployment mechanisms.
No timeline for development or orbital testing has been announced. The concept remains in the theoretical phase, with researchers acknowledging that practical hurdles — including deployment accuracy, durability in the space environment, and safe deorbit trajectories — must still be overcome.
If realized, the technology could complement existing debris mitigation strategies, which have so far struggled to keep pace with the rising number of objects in orbit. The Chinese team's work adds to a global push for active debris removal, with agencies like ESA and NASA also exploring similar capture methods.
