Ruling those out, instead what you’d probably be looking at is a Materials International Space Station Experiment (MISSE).

MISSE projects serve as a laboratory to test and study various material samples as they’re exposed to a space environment. Attached on the outside of the ISS, the specimens are simultaneously exposed to a variety of conditions that would be very difficult, if even possible, to mimic on Earth, including exposure to: atomic oxygen, various levels of radiation, vacuum, extreme temperatures, and zero gravity. While MISSE wasn’t ...
