Video from the navigation camera aboard NASA’s Ingenuity Mars Helicopter
shows its record-breaking 25th flight on April 8, 2022. Covering 2,310 feet
(704 meters) at a maximum speed of 12 mph (5.5 meters per second), it was the
rotorcraft’s longest and fastest flight to date. Credits:

Imagery has come down from Mars capturing a recent flight in which the
rotorcraft flew farther and faster than ever before.
The Ingenuity Mars Helicopter’s black-and-white navigation camera has
provided dramatic video of its record-breaking 25th flight, which took place on
April 8. Covering a distance of 2,310 feet (704 meters) at a speed of 12 mph
(5.5 meters per second), it was the Red Planet rotorcraft’s longest and fastest
flight to date. (Ingenuity is currently preparing for its 29th flight.)
“For our record-breaking flight, Ingenuity’s downward-looking navigation
camera provided us with a breathtaking sense of what it would feel like gliding
33 feet above the surface of Mars at 12 miles per hour,” said Ingenuity team
lead Teddy Tzanetos of NASA’s Jet Propulsion Laboratory in Southern California.
The first frame of the video clip begins about one second into the flight.
After reaching an altitude of 33 feet (10 meters), the helicopter heads
southwest, accelerating to its maximum speed in less than three seconds. The
rotorcraft first flies over a group of sand ripples then, about halfway through
the video, several rock fields. Finally, relatively flat and featureless
terrain appears below, providing a good landing spot. The video of the
161.3-second flight was speeded up approximately five times, reducing it to
less than 35 seconds.
The navigation camera has been programmed to deactivate whenever the
rotorcraft is within 3 feet (1 meter) of the surface. This helps ensure any
dust kicked up during takeoff and landing won’t interfere with the navigation
system as it tracks features on the ground.
Ingenuity’s flights are autonomous. “Pilots” at JPL plan them and send
commands to the Perseverance Mars rover, which then relays those commands to
the helicopter. During a flight, onboard sensors – the navigation camera, an
inertial measurement unit, and a laser range finder – provide real-time data to
Ingenuity’s navigation processor and main flight computer, which guide the
helicopter in flight. This enables Ingenuity to react to the landscape while
carrying out its commands.
Mission controllers recently lost communication with Ingenuity after the helicopter entered a low-power state. Now
that the rotorcraft is back in contact and getting adequate energy from its
solar array to charge its six lithium-ion batteries, the team is looking
forward to its next flight on Mars.
More About Ingenuity
The Ingenuity Mars Helicopter was built by JPL, which also manages the
project for NASA Headquarters. It is supported by NASA’s Science Mission
Directorate. NASA’s Ames Research Center in California’s Silicon Valley and
NASA’s Langley Research Center in Hampton, Virginia, provided significant
flight performance analysis and technical assistance during Ingenuity’s
development. AeroVironment Inc., Qualcomm, and SolAero also provided design assistance
and major vehicle components. Lockheed Space designed and manufactured
the Mars Helicopter
Delivery System.
At NASA Headquarters, Dave Lavery is the program executive for the
Ingenuity Mars Helicopter.
