A small helicopter opened a new chapter of space exploration this morning when it lifted off the surface of Mars, marking humankind's first powered flight on another planet. The 19-inch-tall chopper called Ingenuity kicked up a little rusty red dust as it lifted about 10 feet off the ground, hovered in place, turned slightly, and slowly touched back down. The flight lasted only about 40 seconds, but it represents one of history's most audacious engineering feats. "A lot of people thought it was not possible to fly at Mars," says MiMi Aung, the project manager of Ingenuity at NASA's Jet Propulsion Laboratory (JPL). "There is so little air."
