Researchers propose $200K satellite bond to force orbital cleanup before space debris catastrophe
A refundable deposit scheme published in Nature Communications aims to incentivize satellite operators to deorbit defunct spacecraft and prevent cascade collisions in low Earth orbit.
What happened
Researchers at University of Colorado Boulder and University College London published a paper proposing that satellite operators post a $200,000 refundable bond before launch, recoverable with interest only upon successful deorbiting. The bond funds forfeited by non-compliant operators would flow into a shared pool for active debris-removal missions. Currently, 60% of satellites remain in orbit when their propellant runs out despite guidelines from international bodies requesting removal within 25 years and FCC standards requiring five-year removal for U.S.-licensed low Earth orbit satellites. The researchers estimate that covering just 20% of global launches would reduce derelict satellites by 18%.
Context
Low Earth orbit contains over 57,000 pieces of tracked space debris larger than four inches, according to the European Space Agency—double the figure from less than a decade ago. Space sustainability experts have long warned that the growing constellation launches planned by SpaceX, Blue Origin, and Amazon could trigger Kessler Syndrome, a cascade of orbital collisions rendering space unusable. The proposed policy sidesteps international coordination challenges by operating at national level; the EU could enforce compliance by restricting market access for companies wanting to sell space products to its 300-400 million consumers, similar to GDPR enforcement. The scheme parallels U.S. oil operator bonds in place since the 1960s, which ensure abandoned wells are plugged. Recent data shows increasing fragmentation events: LeoLabs reported at least four such incidents in six months, collectively creating hundreds of new debris pieces.
