RED PLANET – NASA’s Ingenuity Mars Helicopter became the first aircraft in history to make a powered, controlled flight on another planet.
The team of Ingenuity, which has 1.8-kilogram weight, at the agency’s Jet Propulsion Laboratory in Southern California confirmed the feat after receiving data from the helicopter via NASA’s Perseverance Mars rover.
The historic achievement will pave way for further space exploration.
“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 in a statement, released by NASA.
“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.”
The solar-powered helicopter first became airborne at 3:34 a.m. EDT (12:34 a.m. PDT) – 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 (3 meters) 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 one of NASA’s technology demonstration projects, the 19.3-inch-tall (49-centimeter-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% the pressure at the surface compared to our planet. This means there are relatively few air molecules with which Ingenuity’s two 4-foot-wide (1.2-meter-wide) rotor blades can interact to achieve flight.
Parked about 211 feet (64.3 meters) away at Van Zyl Overlook during Ingenuity’s historic first flight, the Perseverance rover not only acted as a communications relay between the helicopter and Earth, but also chronicled the flight operations with its cameras. The pictures from the rover’s Mastcam-Z and Navcam imagers will provide additional data on the helicopter’s flight.
