Tranquility Coronagraph
The legislative preservation of extraterrestrial heritage functions as a mechanism of territorial enclosure, transforming open space into an exclusionary void before physical occupation occurs.

wall text
Under the 2020 One Small Step to Protect Human Heritage in Space Act, US law established a mandatory two-kilometer exclusion perimeter around Tranquility Base. Rather than preserving historic artifacts through public custody, this legislative designation operates as pre-emptive enclosure. The project transposes solar coronagraphy—an optical technique developed to mask blinding stellar disks—into an apparatus of spatial policing. Using small-angle trigonometry, the legal boundary is converted into a 1.07 arcsecond micro-aperture mask milled from aluminum. Inserted into the focal plane of an Earth-bound telescope, it physically extinguishes incoming photons from the site, rendering heritage protection indistinguishable from complete optical erasure.

anchor facts used
- The 'One Small Step to Protect Human Heritage in Space Act' was enacted on December 31, 2020.
- The law legally mandates a 2-kilometer Keep-Out Zone (KOZ) around the Apollo 11 landing site.
- Tranquility Base is located at exactly 0°40'26.69"N 23°28'22.69"E.
mechanism
- Ephemeris tracking — Targets a static historic coordinate rather than a celestial body.
1. Track the exact lunar ephemeris of 0°40'26.69"N 23°28'22.69"E using a motorized equatorial telescope mount. - Small-angle approximation — Translates a legal terrestrial boundary into an optical measurement.
2. Calculate the optical angular diameter of a 2-kilometer radius on the lunar surface as viewed from Earth's current orbital distance. - Coronagraphic Masking — Used to block a legally protected human artifact rather than a glaring star.
3. Mill a micro-opaque focal-plane mask matching the calculated angular diameter to physically block incoming photons from the designated area. - Focal plane occlusion — Enforces a legal keep-out zone at the level of optical perception.
4. Inject the mask into the optical path of a public viewing telescope, replacing the expected heritage spectacle with a sharply defined black void.
lineage
- Bernard Lyot's Solar Coronagraph (1939) — Appropriates the instrument designed to reveal stellar coronas to instead obscure human heritage.
- Trevor Paglen, 'The Other Night Sky' (2007) — Inverts Paglen's project: instead of tracking classified satellites, it obscures highly public, legally protected coordinates.
- NASA, 'Recommendations to Space-Faring Entities' (2011) — Directly implements the spatial exclusion radii established in this foundational policy document.

SCORE 4/5 after 1 attempt(s)
READS: The mechanical transposition of astronomical coronagraphy into legal occlusion is clear. The CNC schematic directly ties statutory keep-out zones to angular focal-plane dimensions, producing a literal black void over the Apollo 11 coordinates.
FAILS: The video movement is subtle drift rather than deliberate tracking, making the mask feel like a post-production graphical overlay rather than a physical optical element seated inside the telescope barrel.
