The Ingenuity helicopter paved new floor (air?) in April 2019, when it communicated data of its first flight—the first powered, controlled flight on another planet—to NASA scientists on Earth.
However now, it appears Ingenuity isn’t excited about speaking with its engineering group in any respect; as of late, the Mars helicopter has solely communicated with NASA scientists intermittently and unpredictably.
The communication breakdown is making it tough for the Ingenuity group to information the craft across the Martian panorama—and crucially, each inside vary however safely away from the Perseverance rover, the actual star of the Mars 2020 program.
In keeping with a status update written by Travis Brown, Ingenuity’s chief engineer, the communication issues began in earnest following Ingenuity’s forty ninth flight on April 2, 2023, which set information for the rotorcraft’s top and airspeed.
Following downlink of knowledge from its forty ninth flight, the Ingenuity group did not uplink directions for the rotocraft’s subsequent flight.
However the points with Ingenuity’s communication return farther, Brown wrote. Shortly after the rotorcraft’s fortieth flight in January 2023, Ingenuity started combating “brownouts”—durations wherein the chopper would slip into its low-power mode, which retains the craft alive throughout harsh winter nights on Mars. Final 12 months, a cold-induced low energy state gave NASA engineers a similar scare about the helicopter’s survivability.
It grew to become tough to foretell when Ingenuity would wake from these brownouts, in flip making it tough for the group to coordinate the rotorcraft’s flights. All of the whereas, the Perseverance rover has been persevering with its procession throughout Jezero Crater’s western rim, investigating a dried-up river delta for areas of geological and astrobiological curiosity.
On Sol 755, the group misplaced contact with the helicopter once more, and there was radio silence for the subsequent week (a Sol on Mars, or a single Martian day, is roughly 24 hours, 39 minutes, and 35 seconds lengthy). The group started to think about the likelihood that Ingenuity had died. “In additional than 700 sols working the helicopter on Mars, not as soon as had we ever skilled a complete radio blackout,” Brown stated within the blog post. However on Sols 761 and 762, singular radio pings confirmed the spunky area helicopter continued.
The group decided {that a} Martian ridge between Perseverance and Ingenuity was obstructing communications from the helicopter. Since Ingenuity has transitioned from a tech demo of flight on other worlds to a scout for Perseverance, which is charged with investigating the Jezero Delta, the helicopter has usually stayed in entrance of the rover’s projected path.
That made flight 50 a detailed shave for the helicopter group. They managed to uplink flight directions to the rover as Perseverance approached it, attending to inside 262 ft (80 meters) of the helicopter.
Brown famous that mud on the helicopter’s photo voltaic panels means the cat-and-mouse sport could persist, as Ingenuity could wrestle to get energy. Hopefully the group doesn’t encounter comparable buildup to that which ended the InSight lander mission late final 12 months.
