Keep-Out Zone: Rarefied Gas Dynamics

Extraterrestrial heritage preservation relies not on erecting physical fences, but on the invisible mathematical enforcement of gas-dust kinematic models to prevent forensic erasure by future systems.

Kinematic ejecta vectors calculate the mathematical perimeter of lunar preservation. · motion: mathematically expanding the buffer zone

wall text

Preserving extraterrestrial heritage cannot rely on physical barriers in vacuum environments. Instead, protective perimeters are dictated by Direct Simulation Monte Carlo (DSMC) and ballistic ejecta kinetics. When rocket plumes strike unshielded regolith, hypervelocity dust particles act as abrasive sandblasters capable of stripping historical artifacts and erasing fragile footprint impressions kilometers away. This work visualizes the invisible gas-kinetic boundary condition codified in the 2020 One Small Step Act, where spatial geofencing functions as an active forensic shield calculated against hypervelocity particle abrasion.

anchor facts used

The 'One Small Step to Protect Human Heritage in Space Act' (US Public Law 116-328) was enacted in December 2020 to legally shield Apollo sites.
The law mandates adherence to NASA's 2011 guidelines, which established a 2-kilometer descent/landing 'Keep-Out Zone' (KOZ) around the Apollo 11 and 17 sites.
In a lunar vacuum, descending spacecraft exhaust accelerates regolith particles to velocities exceeding 2,000 meters per second, creating highly destructive, sandblasting dust plumes.

curatorial qa (machine verdict, unedited)

SCORE 3/5 after 2 attempt(s)
READS: The red wireframe keep-out dome and high-velocity ballistic particle ejection rays clearly communicate lunar exhaust dispersion over Apollo 11 topography.
FAILS: The descent engine inexplicably fires from the preserved lander itself rather than showing an incoming encroaching craft, and the buffer zone grid remains static instead of mathematically expanding.
