"When running an accident investigation from 100 million miles away, you don't have any black boxes!" NASA's Håvard Grip said.

Imagine how much more difficult it would be to diagnose a helicopter accident that took place 69 million miles away with none of the usual data present to help. NASA had to do just that after its Ingenuity Mars Helicopter suffered an accident on Jan.

Engineers now say they understand the most likely cause of the Ingenuity helicopter's crash landing on Mars earlier this year.

Ingenuity may never fly above the surface of Mars again, but the downed helicopter is otherwise healthy and could serve as a weather station for decades, JPL says.

The Ingenuity helicopter flew on Mars for an incredible 72 flights. Now, NASA has shared findings of why the mission came to an end.

NASA has made history by conducting the first-ever aircraft accident investigation on another planet. The focus of the investigation was the Ingenuity Mars Helicopter, which experienced a hard landing during its 72nd flight on January 18,

Engineers from NASA's Jet Propulsion Laboratory in Southern California and AeroVironment are completing a detailed assessment of the Ingenuity Mars Helicopter's final flight on Jan. 18, 2024, which will be published in the next few weeks as a NASA technical report.
