See NASA’s Ingenuity Mars Helicopter Fly in 3D

A new video of the helicopter’s third flight gives viewers the sensation of standing on the Red Planet and seeing the action firsthand

Engineers at Jet Propulsion Laboratory have rendered the flight of the Mars Ingenuity Helicopter in 3D, lending dramatic depth to the flight as the craft ascends, hovers, then zooms laterally off-screen before returning for a pinpoint landing. 

Located on the Mars Perseverance rover’s mast, or “head,” the zoomable dual-camera Mastcam-Z imager provided the view. Along with producing images that enable the public to follow the rover’s daily discoveries, the cameras provide key data to help engineers navigate and scientists choose interesting rocks to study.

Justin Maki, an imaging scientist at JPL, led the team that stitched the images into a video. The frames of the video were reprojected to optimize viewing in an anaglyph, or an image seen in 3D when viewed with color-filtered glasses

Maki’s been creating 3D imaging of Mars since his days as a graduate student processing images from NASA’s Sojourner, the first Mars rover in 1997, But this is the first time he’s created actual 3D video of an aircraft flying on Mars, according to a story published by NASA. 

“The Mastcam-Z video capability was inherited from the Mars Science Laboratory MARDI (MArs Descent Imager) camera,” Maki said. “To be reusing this capability on a new mission by acquiring 3D video of a helicopter flying above the surface of Mars is just spectacular.” The videos of the helicopter are the most extensive 3D video yet from the Mastcam-Z team.

The rover’s drivers and robotic-arm operators use a more sophisticated 3D system to understand exactly how things are positioned on Mars before planning the rover’s movements. But, according to Maki, team members have also been viewing still 3D images for rover-drive planning. “A helicopter flying on Mars opens a new era for Mars exploration. It’s a great demonstration of a new technology for exploration,” he added. “With each flight we open up more possibilities.”

The April 25 flight brought with it several other firsts, with Ingenuity rising 16 feet (5 meters), then flying downrange 164 feet (50 meters). That was a record until Ingenuity traveled 873 feet (266 meters) on its fourth flight, on April 30. For its fifth flight, on May 7, Ingenuity completed its first one-way trip, traveling 423 feet (129 meters), then reaching an altitude of 33 feet (10 meters) above its new landing field.

The flights began as a technology demonstration intended to prove that powered, controlled flight on Mars is possible. Now they will serve as an operations demonstration, exploring how aerial scouting and other functions could benefit future exploration of Mars.
