NASA's Ingenuity Helicopter Succeeds In Historic First Flight On Mars

nasa ncam 041921 lt

Monday, NASA's Ingenuity Mars Helicopter became the first aircraft in history to make a powered, controlled flight on another planet. The Ingenuity team at the agency's Jet Propulsion Laboratory in Southern California confirmed that the flight succeeded after receiving data from the helicopter via NASA's Perseverance Mars rover at 6:46 a.m. EDT.

"Ingenuity is the latest in a long and storied tradition of NASA projects achieving a space exploration goal once thought impossible," said acting NASA Administrator Steve Jurczyk. "The X-15 was a pathfinder for the space shuttle. Mars Pathfinder and its Sojourner rover did the same for three generations of Mars rovers. We don't know exactly where Ingenuity will lead us, but today's results indicate the sky - at least on Mars - may not be the limit," he added.

The solar-powered helicopter first became airborne at 3:34 a.m. EDT, or 12:33 Local Mean Solar Time (Mars time) - a time the Ingenuity team determined would have optimal energy and flight conditions. Altimeter data indicate Ingenuity climbed to its prescribed maximum altitude of 10 feet and maintained a stable hover for 30 seconds. It then descended, touching back down on the surface of Mars after logging a total of 39.1 seconds of flight.

Ingenuity's initial flight demonstration was autonomous - piloted by onboard guidance, navigation, and control systems running algorithms developed by the team at JPL. Because data must be sent to and returned from the Red Planet over hundreds of millions of miles using orbiting satellites and NASA's Deep Space Network, Ingenuity cannot be flown with a joystick, and its flight was not observable from Earth in real time.

NASA Associate Administrator for Science Thomas Zurbuchen announced the name for the Martian airfield on which the flight took place as Wright Brothers Field.

As one of NASA's technology demonstration projects, the 19.3-inch-tall Ingenuity Mars Helicopter contains no science instruments inside its tissue-box-size fuselage. Instead, the 4-pound rotorcraft is intended to demonstrate whether future exploration of the Red Planet could include an aerial perspective.

This first flight was full of unknowns. The Red Planet has a significantly lower gravity - one-third that of Earth's - and an extremely thin atmosphere with only 1 percent the pressure at the surface compared to earth. This means there are relatively few air molecules with which Ingenuity's two rotor blades can interact to achieve flight. The helicopter contains unique components, as well as off-the-shelf-commercial parts - many from the smartphone industry - that were tested in deep space for the first time with this mission.

Perseverance touched down with Ingenuity attached to its belly on February 18. Deployed to the surface of Jezero Crater on April 3, Ingenuity is currently on the 16th sol, or Martian day, of its 30-sol (31-Earth day) flight test window. Over the next three sols, the helicopter team will receive and analyze all data and imagery from the test and formulate a plan for the second experimental test flight, scheduled for not earlier than April 22. If the helicopter survives the second flight test, the Ingenuity team will consider how best to expand the flight profile.
