NASA Thinks It Knows Why Ingenuity Crashed On Mars

NASA Thinks It Knows Why Ingenuity Crashed On Mars
NASA believes Ingenuity's navigation system was responsible for its crash on the surface of Mars. Engineers determined that the helicopter's navigation system struggled to track features over smooth terrain, leading to a hard landing and structural failure. Universe Today reports: Now, almost a year after the incident, a team of engineers from NASA's Jet Propulsion Laboratory have been analyzing the data. Their findings will be published in the next few weeks however the team of engineers assert it was harder than expected to complete an accident investigation from 160 million kilometers. The faults lie in the navigation system that was designed to visually track surface features using a camera pointed at the round. The system worked during early flights over more textured terrain but as Ingenuity moved over the Jezero Crater, it began operating over featureless sand ripples.

The navigation system was designed to provide estimates of the helicopter's velocity, chiefly to enable it to land. The data revealed from Flight 72 revealed that the navigation system couldn't find features to track. Images showed that the lack of features led to a harder than usual touchdown leading to a pitch and roll of the craft. The sudden change of attitude led to increase load on the rotors, beyond their designed limits leading to the structural damage. 'Even though Ingenuity will not be able to fly anymore it can still provide weather and avionics data to the Perseverance rover,' notes Universe Today. 'It will help us to understand more about the weather in its vicinity but perhaps its greatest legacy are its hours of flight on an alien world.'
