Navigation error sends NASA’s Mars helicopter on wild ride

CAPE CANAVERAL, Fla. — A navigation timing error sent NASA’s little Mars helicopter on a wild, lurching ride, its first major problem since it took to the Martian skies last month.

Navigation error sends NASA’s Mars helicopter on wild ride

Officials at the Jet Propulsion Laboratory reported Thursday that the experimental helicopter, named Ingenuity, managed to land safely. The trouble cropped up about a minute into the helicopter’s sixth test flight last Saturday at an altitude of 33 feet (10 meters). One of the numerous pictures taken by an onboard camera did not register in the navigation system, throwing the entire timing sequence off and confusing the craft about its location.

According to Havard Grip, the helicopter’s chief pilot, Ingenuity, began tilting back and forth as much as 20 degrees and suffered power consumption spikes.

A built-in system to provide an extra margin for stability “came to the rescue,” he wrote in an online status update. The helicopter landed within 16 feet (5 meters) of its intended touchdown site.

In April, Ingenuity became the first aircraft to make a powered flight on another planet, two months after landing on Mars with NASA’s rover Perseverance.

The 4-pound (1.8-kilogram) helicopter aced its first five flights, each one more challenging than before. NASA was so impressed by the $85 million tech demo that it extended its mission by at least a month.

Saturday’s troubled flight was the first for this bonus period. Engineers have spent the past several days addressing the problem.
