In the face of the growing threat of space junk, space agencies from Europe, the United States, and Russia have proposed cleaning solutions one after another: magnetic cables, forks, robotic arms, and even ground lasers. The schemes are not very practical and not very effective, and more of them remain in the stage of construction or theoretical simulation. China has joined this rank this year, and the researchers are proposing a comprehensive solution: the laser space station.
A group of researchers at Xi'an Air Force Engineering University successfully simulated the process of cleaning small fragments within 10 cm of the on-orbit laser space station. By aligning the debris in two minutes and continuously transmitting 20 times/second of laser pulses, it can change its impact on other satellites or space stations. Orbit, or directly burn it into the atmosphere. Papers related to the simulation have been published in the latest issue of the Optik Optical Journal, but China's addiction to space laser weapons has long since begun.
Although there have always been voices of concern, such as fear that China will use the laser as a weapon to attack satellites or space stations in other countries, the International Space Station is now facing the possible threat of 200 debris collisions per day. Members have been asked to be ready to abandon the station at any time, and any means that may improve the status quo are worth a try. Otherwise, the accident of a wave of debris in the film "Gravity" will be staged in reality, and more than one country will suffer losses.
