Mars Helicopter Spots Perseverance Rover’s Landing Debris

On the 26th flight of Ingenuity, NASA’s helicopter on Mars, it spotted and photographed the wreckage of the Perseverance rover’s landing gear, protective shell, and parachute. From a NY Times article on the photos:

“There’s definitely a sci-fi element to it,” Ian Clark, an engineer who worked on Perseverance’s parachute system, said of photographs released on Wednesday. “It exudes otherworldly, doesn’t it?”

Part of the reason NASA had Ingenuity go take a look is to see how all of that equipment held up during the landing process. Data from the photos will inform future missions.

“Perseverance had the best-documented Mars landing in history, with cameras showing everything from parachute inflation to touchdown,” said JPL’s Ian Clark, former Perseverance systems engineer and now Mars Sample Return ascent phase lead. “But Ingenuity’s images offer a different vantage point. If they either reinforce that our systems worked as we think they worked or provide even one dataset of engineering information we can use for Mars Sample Return planning, it will be amazing. And if not, the pictures are still phenomenal and inspiring.”

In the images of the upright backshell and the debris field that resulted from it impacting the surface at about 78 mph (126 kph), the backshell’s protective coating appears to have remained intact during Mars atmospheric entry. Many of the 80 high-strength suspension lines connecting the backshell to the parachute are visible and also appear intact. Spread out and covered in dust, only about a third of the orange-and-white parachute — at 70.5 feet (21.5 meters) wide, it was the biggest ever deployed on Mars — can be seen, but the canopy shows no signs of damage from the supersonic airflow during inflation. Several weeks of analysis will be needed for a more final verdict.

It is really remarkable, the images we’re seeing from Mars, taken by a robotic helicopter.

A Helicopter Flies on Mars

Ingenuity Shadow

Deployed from NASA’s Perseverance rover, the Ingenuity helicopter took off and hovered for about 30 seconds in its first flight early this morning.

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. Additional details on the test are expected in upcoming downlinks.

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 livestreamed the team in Mission Control as the test results were transmitted back to Earth. The photo above is of Ingenuity’s shadow taken while in flight by its onboard camera.

Update: Here’s video footage of the first flight:
