How to Clean Up After Ourselves in Space

The video discusses the growing problem of space junk and its potential dangers, such as the Kessler syndrome. It explores current solutions like lasers and trash collection missions, which face challenges. The video introduces solar sails, initially developed for deep space missions, as a potential solution to deorbit space junk faster. Drag sails, a variation of solar sails, are being tested to bring down satellites efficiently. These sails could help slow the growth of space debris, offering a promising approach to managing space junk.
