   | High LEO (HLEO)/) | $1,000 - 2,000$ | Reduced drag; minor relativistic effects observable | $105 - 125$ |
   Missions operating in VLEO/), such as those involving aerobraking or atmospheric harvesting systems, must account for the fact that molecular collisions in this zone often impart a slight negative charge accumulation on the leading edge of the spacecraft hull, which affect…
