The Federal Communications Commission (FCC) is proposing to reduce the amount of time operators have to dispose of decommissioned satellites from 25 years to just five years.As The Register reports, the FCC released a Fact Sheet yesterday entitled "Space Innovation; Mitigation of Orbital Debris in the New Space Age." It details how there are currently over 4,800 satellites operating in orbit around the Earth and "many more to come," which will increase the chances of collisions significantly.With that in mind, the current 25-year rule for an operator to perform an uncontrolled re-entry into Earth's atmosphere of a decommissioned satellite no longer seems practical. Instead, the FCC wants to adopt a "five-year rule," whereby disposals should be carried out "as soon as practicable" with five years being the upper limit.The new regulations would also apply to space stations that either end their mission in low-Earth orbit (below 2,000km/1,242 miles) or pass through it. All US-licensed satellites and systems would need to adhere to the new regulations, but so would any non-US-licensed satellites that wish to operate in US markets. There is apparently broad support for the change, including from SpaceX. However, when commercial operators were asked to comment on the proposal last month it was pointed out that the change would have minimal impact. Citing a NASA Orbital Debris Program Office report, it's claimed the new time limit will only lead to a 10% reduction in orbital debris over the next 200 years. NASA deems that "not a statistically significant benefit."
