Nasa successfully flew its tiny helicopter Ingenuity on Mars early yesterday, the first powered flight on another planet and a feat a top engineer called “our Wright brothers’ moment”.
At 3.34am Eastern Time (0734 GMT), the four pound (1.8kg) rotorcraft lifted off, hovered 10’ (3m) above the Martian surface, then came back to rest after 39.1 seconds.
Data and images from the autonomous flight were transmitted 173mn miles (278mn km) back to Earth where they were received by the National Aeronautics and Space Administration (Nasa)’s array of ground antennas and processed more than three hours later.
Engineers were tensely watching their screens at the Jet Propulsion Laboratory (JPL) in California, where the mission had been designed and planned for the past six years.
They broke into applause as one of them read off a checklist of tasks that Ingenuity had achieved and concluded: “Ingenuity has performed its first flight – the first flight of a powered aircraft on another planet.”
Ingenuity quickly sent back a black-and-white image from its downward pointing navigation camera, showing its bug-like shadow cast on the surface.
Then came a choppy colour video from the Perseverance rover, showing Ingenuity on the ground, in flight, and then once again at rest.
More images and a smoothed-out video are expected to follow.
“We’ve been talking so long about our Wright brothers’ moment on Mars, and here it is,” said lead engineer MiMi Aung to her team, as she doled out virtual hugs.
The first powered flight on Earth was achieved by the Wright brothers in 1903 in Kitty Hawk, North Carolina.
A piece of fabric from that plane has been tucked inside Ingenuity in honour of that feat.
Nasa had originally planned the flight for April 11 but postponed it over a software issue that was identified during a planned high-speed test of the aircraft’s rotors.
The issue was later resolved through the help of a software update and tweak in coding.
Ingenuity travelled to Mars attached to the underside of Perseverance, which touched down on the planet on February 18 on a mission to search for signs of extraterrestrial life.
Ingenuity’s goal, by contrast, is to demonstrate its technology works, and it won’t contribute to Perseverance’s science goals.
However, it is hoped that Ingenuity can pave the way for future flyers that revolutionise our exploration of celestial bodies because they can reach areas that rovers can’t go, and travel much faster.
“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,” said acting Nasa Administrator Steve Jurczyk.
The flight was challenging because of conditions vastly different from Earth’s – an atmosphere that has less than 1% the density of our own, and gravitational pull of only one-third.
That made it necessary for Ingenuity’s rotors to achieve around 2,500 revolutions per minute, roughly five times greater than helicopters achieve on Earth.
As well as high-tech components, the aircraft contains many off-the-shelf smartphone parts that were tested in space for the first time on this mission.
Ingenuity was deployed to its “flight strip” on April 3 and is now in the 16th sol, or Martian day, of its 30-sol (31-Earth day) flight test window.
The team will continue to receive and analyse data in the coming days, then formulate a plan for the second flight, which would be no earlier than April 22.


This Nasa photo released yesterday shows members of the Ingenuity helicopter team in the Space Flight Operations Facility at Nasa’s Jet Propulsion Laboratory reacting to data showing that the helicopter had completed its first flight.
