NASA Finds Material that Could Support Possible Life on Saturn’s Moon
He noted that although NASA purposely sent the spacecraft crashing into Saturn’s atmosphere to end its service, Cassini is still proving to be a valuable research tool.

NASA Identifies Cause of Mars Helicopter’s Final Crash
The American space agency NASA says it has found the likely cause of a crash that grounded its Mars helicopter Ingenuity.

NASA Identifies Cause of Mars Helicopter’s Final Crash
Engineers from NASA’s Jet Propulsion Laboratory in California fully investigated Ingenuity’s last flight on Mars.

They found the cause of the crash was linked to the helicopter’s navigation system.

That camera-based system was not able to collect dependable data on elements of the Martian surface to support a safe landing.

They said the helicopter’s last flight saw the aircraft climb to about 12 meters, where it stayed, or hovered, while capturing images of the Martian surface.

Data records show Ingenuity began its planned descent after about 19 seconds.

In past flights, the engineers said the camera was able to find smooth, suitable landing possibilities.
- Public domaingeneral-american

But NASA said during the final flight, the helicopter was traveling in an area with very few surface features for the camera to capture.
- Public domaingeneral-american

This meant the aircraft’s navigation system could not find enough of these features to choose a good landing spot.
