    Space station sextant experiment

    NASA Space Station On-Orbit Status 23 August 2018 - Studying An Ancient
    Navigation Technique
    
    "Sextant Navigation: Today the crew performed a session for the Sextant
    Navigation investigation. The crew collected the data and recorded the
    results for ground evaluation. This session focused on stable sighting
    position identification and evaluation. Astronauts onboard the ISS test
    a hand-held sextant that is intended for use on future Orion exploration
    missions. The results from this investigation can aid in the development
    of emergency navigation methods for future manned spacecraft.
    Historically, Gemini missions in 1965-66 were the first to exercise
    sextant sightings from a spacecraft. A sextant was built into Apollo
    vehicles as a navigation backup in case of lost communications."
