Meeting the five-year rule without propulsion
Satellites launched after 29 September 2024 under FCC authorization must re-enter within five years of the end of their mission. For a spacecraft without propulsion the rule becomes an altitude ceiling that depends on its ballistic parameter and on the Sun. With the lifetime model of the PocketQube review, a fully loaded 1P stays within five years below 559 km at moderate activity, between 493 and 627 km from low to high activity, while 1U, 3U and 12U CubeSats are limited to 525, 513 and 494 km. Above the ceiling, a tumbling drag sail of 80 cm² brings a 1P down from 600 km at moderate activity, but about eight times more at low activity, and a perigee-lowering burn costs 70–150 m/s, a seventh of a 1P’s mass in cold gas at 600 km. For PocketQubes the release orbit is the compliance strategy.

Orbital decay and lifetime of PocketQubes and CubeSats
We derive the drag-driven decay of a circular low Earth orbit from the energy equation, evaluate it with the single-scale-height density model of Kennewell driven by F10.7 and Ap, and produce lifetime tables for PocketQube and CubeSat form factors from 300 to 650 km. From 500 km at moderate activity a fully loaded 1P lives 1.7 years and a 1U 3.1 years; solar activity alone moves the 1P between 0.7 and 5.8 years. Checked against the re-entries of Grizu-263A and Delfi-PQ, both released from Transporter-3, the model overestimates lifetime at constant flux, as expected from a single scale height and the fast rise of Solar Cycle 25. We close with how lifetimes should be reported.
