Ingenuity Just Survived an Unexpected in-Flight Anomaly on Mars!


28 MAY 2021
During its sixth flight on the red planet, the Ingenuity helicopter experienced a little mishap - but, thanks to planning and built-in failsafes, it survived to fly another day.
 
This is actually great news, because it demonstrates the multiple ways in which the vehicle is robust to errors - as well as giving engineers here at home an opportunity to patch them.
The event took place on 22 May 2021 - the 91st Martian day of the Perseverance mission. The sky was clear and bright, perfect for Ingenuity s task: demonstrating its ability to take aerial stereo images.
The little helicopter was to vertically ascend to a height of 10 meters (33 feet), then make a horizontal flight of three legs - southwest for 150 meters, at which point it would turn and move 15 meters in a southward direction while taking images, before turning northeast and flying for another 50 meters before landing, all at a speed of about 4 meters per second (8.9 mph). ....

NASA's Mars Helicopter Lost Control In Mid-Air Due To A Navigation Error | WJBO Newsradio 1150 AM & 98.7 FM

The helicopter on NASA s Mars rover Perseverance had a scare during its sixth test flight. The Ingenuity helicopter ran into problems shortly after taking off when a navigation error caused it to lose control while it was 33 feet off the ground.
Officials at NASA s Jet Propulsion Laboratory said the issue occurred when a photo taken from an onboard camera failed to register in the craft s navigation system. That caused a chain reaction, as all subsequent images loaded into the system had an inaccurate time stamp. As a result, the helicopter began to tilt back and forth as much as 20 degrees because the navigation systems couldn t identify its location. ....
