As the Mars helicopter – Ingenuity – hovered above the surface of Mars on April 19, 2021, its own navigation camera captured its shadow on the Martian surface. This successful first flight was a technology demonstration for powered flight on Mars.

NASA’s Mars helicopter Ingenuity successfully flew in the thin air of Mars on April 19, 2021. The team at NASA’s Jet Propulsion Laboratory in Pasadena, California broke into cheers as flight controllers announced the success of this first demonstration flight. It was the first powered, guided flight on another planet. Expected to follow are a handful of other test flights over a month-long campaign that aims to show that aerial exploration is feasible in Mars’ thin atmosphere.

NASA coverage began at 1015 UTC (6:15 a.m. EDT; translate UTC to your time) on April 19. A post-flight press conference is scheduled for 1800 UTC (2 p.m. EDT) on Monday. You can watch on NASA TV, the NASA smartphone app and on NASA’s website. The Jet Propulsion Laboratory in Pasadena, California – the facility that manages the helicopter’s activity – was broacasting the flight live on its YouTube and Facebook channels.

The helicopter’s first experimental flight was originally scheduled for April 11. Before the flight could happen, NASA needed to reinstall the software to fix a problem that arose when engineers tried to switch the helicopter from pre-flight to flight mode.

Ingenuity arrived at Mars on February 18 along with the Perseverance rover, having made the long trek out to the red planet tucked inside the rover’s belly. JPL wrote in a tweet posted early in the day on April 8:

Ingenuity’s flight preparation process has been slow and cautious, in part because the 4 pound (1.8 kg) helicopter made the journey to Mars in a folded configuration. It was tucked inside the rover’s body behind a protective shield. But after the rover dropped that shield and drove to the airfield, the helicopter’s personnel ordered the device to unpack and slowly unfold itself. Then, Perseverance had to set Ingenuity directly on the Martian surface and drive away, allowing the helicopter’s solar panels to begin supporting the aircraft.

Unlocking and testing Ingenuity’s blades marked the last major preparation milestones before the helicopter attempted its first flight. NASA officials tested the blades first at 50 and then at 2,400 revolutions per minute before the helicopter took off.

Due to Ingenuity’s success, future red planet missions may commonly include helicopters, which could serve as scouts for rovers and gather data on their own, NASA officials have said. Ingenuity won’t gather any data, since the small rotorcraft doesn’t carry any scientific instruments. But it will document its upcoming flights with a high-resolution camera. And Perseverance will be watching as well, from a safe distance away. There’s even a chance that the rover could record audio of Ingenuity’s flights using its two onboard microphones, NASA officials have said.

Meanwhile, as Ingenuity made its flight preparations and eventually took off on its first flight on April 19, 2021, Perseverance has been looking at its surroundings and sending back images. Among other activities, the car-sized rover has been snapping photos of its own tire tracks and its sophisticated science arm.

A magnificent new photo mosaic (below) shows NASA’s Mars Perseverance rover and Ingenuity helicopter. Community scientist Seán Doran created it by stitching together 62 photos taken by the rover. Doran posted via his Twitter account, @_TheSeaning. He said he put the constituent images through a “de-noise, repair and upscale process” prior to combining them: a process he calls “laborious.” The payoff is seen below.

Ingenuity also snapped its first color photograph on April 3, shortly after being lowered to the Martian dirt by the Perseverance rover. The image shows the floor of Mars’ 28-mile-wide (45 km) Jezero Crater and a portion of two wheels of NASA’s Perseverance Mars rover. Doran told Space.com:

Focusing on the connection between Percy and Ginny was an obvious choice for this composition. It is very exciting to see any new photos from another planet, but this one is very special, and I expect the technology demo to be a great success.

After Ingenuity’s work is done, Perseverance will begin the main objectives of its own science mission. The six-wheeled robot will hunt for signs of ancient Mars life and collect and cache dozens of samples for future return to Earth.

NASA chose Jezero Crater as the landing site for the Perseverance rover with good reason. Scientists believe the area was once flooded and home to an ancient water river delta more than 3.5 billion years ago. River channels spilled over the crater wall and created a lake, carrying clay minerals from its surroundings. Microbial life could have lived in the crater during one or more of these wet periods, and if so, signs of their remains might be found in lakebed or shoreline sediments. Scientists will study how the region formed and evolved, seek signs of past life, and collect samples of Mars rock and soil that might preserve these signs.

Bottom line: The Mars helicopter Ingenuity flew for the first time on Monday, April 19, 2021, in the early morning hours. Flight coverage began at 1015 UTC (6:15 a.m. EDT; translate UTC to your time). A post-flight press conference is scheduled for 1800 UTC (2 p.m. EDT) on Monday. You can watch on NASA TV and NASA smartphone app, NASA’s website. The Jet Propulsion Laboratory – the facility that manages the helicopter’s activity – broadcast the flight live on its YouTube and Facebook channels.
