During its 54th flight on Mars, NASA's helicopter Ingenuity captured an image of the space agency's Perseverance rover. Space.com reports: Perseverance is nearly out of frame at the top of the photo, which Ingenuity took when it was about 16 feet (5 meters) above the red dirt. Unlike previous sorties, the Aug. 3 flight wasn't a scouting run to aid Perseverance's science activities. It lasted just 24 seconds, reached a maximum altitude of 16 feet and covered no ground laterally, according to Ingenuity's flight log. The mission team designed this short and simple hop in an attempt to help understand what happened during Ingenuity's previous flight, which was cut short unexpectedly.
The mission team designed this short and simple hop in an attempt to help understand what happened during Ingenuity's previous flight, which was cut short unexpectedly. That July 22 sortie was supposed to last 136 seconds and feature several complicated maneuvers. However, Ingenuity stayed aloft for just 74 seconds, touching down after something triggered its "flight-contingency program." [...] Imagery from Ingenuity's navigation camera likely got out of sync with its inertial measurement unit, which helps the little chopper determine its position, speed and orientation. This also happened near the end of Ingenuity's sixth flight, back in May 2021. The mission team soon uploaded a software patch to deal with the issue, but that patch apparently couldn't handle what happened on Flight 53, NASA officials said in the statement. "Since the very first flight, we have included a program called 'LAND_NOW' that was designed to put the helicopter on the surface as soon as possible if any one of a few dozen off-nominal scenarios was encountered," Teddy Tzanetos, Ingenuity team lead emeritus at NASA's Jet Propulsion Laboratory in Southern California, said in a statement.
"During Flight 53, we encountered one of these, and the helicopter worked as planned and executed an immediate landing," Tzanetos added.
