Findings from first archaeology project in space | Science & Technology

Findings from the research team behind the International Space Station Archaeological Project (ISSAP) were published in the journal PLOS ONE. Archaeologist Justin Walsh of Chapman University is available to discuss the discoveries of the team’s first on-orbit project, the Sampling Quadrangle Assemblages Research Experiment (SQuARE).

While Earth-bound archaeologists dig one-meter squares to understand a site and strategize further study, the ISSAP team had the astronauts use adhesive tape to define one-meter areas of the International Space Station and document them with daily photographs to study how the spaces were used over 60 days in 2022. The squares were placed in a handful of work and leisure locations on the space station, including the U.S. galley table, workstations, experimental EXPRESS racks and on the wall across from the latrine where astronauts kept their toiletries.

The team’s findings provide the first glimpse into how astronauts adapt to life and conduct research without gravity, how international cooperation plays out in the tight quarters, how they use their space for work and leisure while in orbit, and more. By cross-referencing the photos with astronaut activity reports, the researchers found that the area near the exercise equipment and latrine, while not designated for any particular purpose, had been used as storage for toiletries, resealable bags, and a rarely used computer. The equipment maintenance area was actually used for storage, with little maintenance carried out there.

Beyond informing the future of space habitats, these findings demonstrate how traditional archaeological techniques can be adapted to study extreme and remote habitats, such as Antarctic research stations or the peak of…
