First Controlled Flight of Mars Helicopter Prototype

This image shows a test flight of a full-scale prototype of the Ingenuity Mars Helicopter. The flight took place on May 31, 2016, in the 25-foot-wide, 85-foot-tall (8-meter-by-26-meter) Space Simulator Facility at NASA's Jet Propulsion Laboratory in Southern California. The flight was the first demonstration that powered-controlled flight could be successfully executed in Mars-like conditions. The simulator's vacuum chamber allows engineers to test spacecraft and components in conditions like those they would face on Mars. https://photojournal.jpl.nasa.gov/catalog/PIA26233
