Ingenuity Mars Helicopter Pilot's Logbook

This image of the official pilot's logbook for the Ingenuity Mars Helicopter flights — the "Nominal Pilot's Logbook for Planets and Moons" — was taken at NASA's Jet Propulsion Laboratory in Southern California on April 19, 2021, the day of Ingenuity's first historic flight. Pilot logbooks are used by aviators to provide a record of their flights, including current and accumulated flight time, number and locations of takeoffs and landings, as well as unique operating conditions and certifications. https://photojournal.jpl.nasa.gov/catalog/PIA24440
