NASA has found 'UFO' debris on Mars
Experts from the US space agency spotted the mystery debris dangling from the bottom of its unmanned helicopter as it left the Red Planet.
The "foreign object debris" (FOD) was captured by the craft's navigation camera and NASA is now attempting to find out what it is and where it came from.
A spokesman said: "The FOD is seen in Navcam imagery from the earliest frames to approximately halfway through the video when it fell from the leg and drifted back to the Mars surface."
The space agency confirmed that the debris had not caused any damage to the craft and that the investigations were ongoing as boffins try to find out more about Mars.
NASA said: "All telemetry from the flight and a post-flight search and transfer are nominal and show no indication of vehicle damage."
