When will ingenuity helicopter fly on Mars?
NASA will attempt the first flight of its Mars helicopter Ingenuity as early as Monday (April 19) after the tiny drone passed a critical test this weekend. The helicopter is targeted to take off at 3:30 a.m. EDT (0730 GMT) on Monday, NASA said today (April 17). Space.comNASA may attempt 1st Mars helicopter flight on Monday
Did 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 images could come at 6:15 am EDT (1015 GMT).
On Monday (April 19), the ultra-lightweight robot will try taking off into the Martian sky and if it succeeds, this maneuver will be the first powered, controlled flight on another planet. Ingenuity is scheduled to take off at 3:30 a.m. EDT (0730 GMT) on Monday, but its flight controllers are wary.
"Our team considers Monday’s attempted first flight like a rocket launch: We’re doing everything we can to make it a success, but we also know that we may have to scrub and try again," said MiMi Aung, Ingenuity project manager at JPL, wrote in a NASA blog post Saturday (April 17). "In engineering, there is always uncertainty, but this is what makes working on advanced technology so exciting and rewarding."
Monday's flight will mark the second time NASA has been poised to fly Ingenuity on Mars. The Mars helicopter's first flight attempt on April 11 was delayed by a timing glitch in its systems, which mission engineers have addressed.

NASA's Perseverance rover will act as the communications intermediary between the helicopter, orbiting spacecraft assisting the flight, and mission control. The rover will be an active observer as well by taking photos and video of this first flight at a distance of 330 feet (100 meters) away from Ingenuity's airfield.
The first thing they'll do is verify they got the data correctly, and then the information is looked over for evidence that Ingenuity ascended, hovered and landed. They'll confirm these findings with altimeter data to then know for certain whether or not the flight occurred.
On Monday, the team will also get a look at black-and-white navigation photos taken by the 0.5 megapixel downward-facing camera on the bottom of the Ingenuity's fuselage, according to Canham. Other images, like the color views coming from Perseverance, will likely be downlinked later. Ingenuity is also equipped with a one-color 13 megapixel horizon-facing terrain camera, but it's not yet clear when those will be available to the public.
Aung added that the chopper's energy profile, thermal models, and rotor operating speeds all look great, and that its sensors have been turned on. All is ready to go for a potentially historic operation. "We will test, prove, and learn regardless of the outcome in this first attempt," Aung said.
That approach proved handy when Ingenuity suffered a glitch with a "watchdog" timer during final tests for its first flight attempt on April 11. The issue forced NASA to stand down from the flight attempt while engineers came up with a software fix. In fact, they came up with two.
"If our initial approach to flight does not work, the rover will send the new flight control software to the helicopter," Aung wrote Saturday. "We will then require several additional days of preparation to load and test the new software on Ingenuity, redo the rotor tests in this new configuration, and recycle for a first flight attempt."
Flying on Mars is no simple feat. The Red Planet's atmosphere is very different from the one cloaking Earth.
"It's very difficult to fly on Mars," Amelia Quon, Ingenuity chamber test engineer at JPL, explained during the April 9 press conference. "The main reason is that the atmosphere is very, very thin. It's about one percent of the density of the atmosphere at [Earth's] sea level. That's the equivalent of about 100,000 feet of altitude on Earth, or three times the height of Mount Everest. We don't generally fly things that high. Commercial airliners fly at about 35,000 feet; the Earth record for helicopter altitude at about 41,000 feet … Mars has a thinner atmosphere than Earth, but that's not really enough to counteract the effects of that thin atmosphere."
