When will ingenuity fly on Mars?
NASA has rescheduled the first flight of its Ingenuity Mars helicopter to April 19th at 3:30AM ET, the agency announced Saturday. The four-pound helicopter that arrived on Mars on February 18th with its parent rover Perseverance has seen its first flight delayed a few times.

The first time the little chopper attempted the test, it test ended early.
During the test, successfully completed on Friday (April 16), the grounded helicopter spun its blades at the speed required for flight, about 2,400 revolutions per minute. The Ingenuity team is evaluating the new data and data about a previously initiated software tweak to decide a new flight date for the 4-lb. (1.8 kilogram) helicopter, according to a NASA statement released Friday night.
When Ingenuity first attempted the test, on April 9, the test stopped as the helicopter's computer was switching from preflight mode to flight mode due to a 'watchdog' timer expiration, NASA said at the time. As a result, NASA announced it would delay the vehicle's first flight, which had been targeting April 11, as the team troubleshooted the misbehaving timer.

The successful spin test came after Ingenuity's personnel tweaked the flight sequence itself, according to the statement. "This approach was tested extensively on both Earth and Mars, and was performed without jeopardizing the safety of the helicopter," NASA officials wrote in the statement.
Engineers had been simultaneously working on a second potential solution that would require reinstalling the helicopter's flight control software, and they aren't quite ready to push aside that work.
"The software swap is a straightforward fix to a known issue," the statement reads. "But, it will take a bit longer to perform and is a modification to software that has remained stable and unchanged for close to two years. Validation and testing have taken several days, and transfer and loading of these new files will take several more."
The team is now evaluating which correction to implement for Ingenuity's first flight, which will be scheduled accordingly. In previous statements about the issue, NASA personnel have said they hope the helicopter will fly sometime next week (the week of April 19).
The news of the successful full-speed spin test came, coincidentally, on the 154th anniversary of the birth of Wilbur Wright, one of the Wright brothers who built the first plane to successfully fly on Earth. Ingenuity carries a small piece of fabric from that plane, dubbed Flyer 1.
Ingenuity has been sitting on what will become its airfield, a flat patch of Jezero Crater, since April 3, when the Perseverance rover gently dropped the helicopter the last few inches to the Red Planet's surface. Ingenuity had made the long trek to Mars folded up and shielded behind the belly pan of the car-sized rover.
Since deploying Ingenuity, Perseverance trundled to the overlook site that engineers selected for it to watch the flight from. The main rover is passing its time by evaluating whether nearby rocks formed during a volcanic eruption or from water depositing sediments.
The mission schedule allots 30 Martian sols (about 31 Earth days) to Ingenuity's flight campaign. After that time runs out, the rover must turn its focus to the geological analysis and sample caching that make up its primary mission on the Red Planet.
