Summary
Overview
Michael Stevens and Hannah Fry explore the fascinating world of archaeology beyond Earth, from the historical artifacts left at Tranquility Base on the moon to ancient manuports that reveal the earliest signs of abstract human thought. The discussion spans space law, territorial ownership, the deepest hole ever drilled on Earth, and how preservation of human sites both on Earth and in space creates a legacy for future civilizations.
Tranquility Base and Space Archaeology
The episode opens with a discussion of Tranquility Base, the Apollo 11 landing site on the moon, which remains littered with human artifacts including bags of waste, equipment, and footprints. NASA can only request that visitors stay 75 meters away, as no international law prevents anyone from disturbing this historic site. This leads to a broader conversation about the four archaeological sites that exist outside national boundaries and the unique challenges of preserving human heritage in space.
- Tranquility Base contains hundreds of items left by Armstrong and Aldrin, including bags of their waste and the lower half of the lunar lander
- The American flag planted at Tranquility Base was knocked over by the ascent blast and has likely been bleached white by solar radiation
- NASA can only request that people stay 75 meters away from the landing site - they cannot legally enforce this as the Outer Space Treaty states no nation owns outer space
- Only four archaeological sites exist outside national boundaries: Tranquility Base, the Titanic wreck, the SS Republic, and Hector Station in Antarctica
" The United States of America agreed in the Outer Space Treaty of the 70s that, yep, no one owns outer space. It's part of the common heritage of mankind. "
Hector Station and the Limits of National Sovereignty
As one of the four archaeological sites outside national boundaries, Hector Station represents a Victorian-era whale oil factory on Desolation Island in Antarctica. The rusted, steampunk-style boilers and deteriorating structures have been naturally preserved by Antarctica's isolation, creating an untouched window into industrial history. This site exemplifies how the absence of national ownership has inadvertently protected it from development or commercialization.
- Hector Station was a whale oil factory built on Desolation Island, Antarctica, before petroleum products replaced whale oil
- The factory boiled whole whales on-site because transporting them back was cost-prohibitive
- Large metal boilers and tanks remain on site, creating a steampunk aesthetic of Victorian industry
- The site has been naturally preserved because Antarctica belongs to no nation and remains isolated from human intervention
" Unlike a lot of other Victorian era artifacts, this one is really untouched because no one goes there. No one's built a pizza hut in a McDonald's next to it. "
