Deorbiting the ISS: The $843 Million Engineering Challenge to Safely Crash a 420-Ton Space Station [2026]
ISS 궤도 이탈: 420톤 우주정거장을 안전하게 추락시키기 위한 8억 4,300만 달러의 엔지니어링 도전 [2026]
Why it matters
NASA is paying SpaceX $843 million to build a spacecraft that will deliberately deorbit the 420-metric-ton International Space Station around 2030, guiding it into a remote ocean area. The ISS cannot remain in orbit permanently due to atmospheric drag and nearly three decades of structural degradation, including cracks and air leaks in aging modules. This controlled reentry represents the most complex demolition ever attempted, with zero margin for error as failure could scatter debris over populated areas.
