By MARCIA DUNNApril 19, 2021 GMTCAPE CANAVERAL, Fla. (AP) — NASA’s experimental Mars helicopter rose from the dusty red surface into the thin air Monday, achieving the first powered, controlled flight on another planet.The triumph was hailed as a Wright Brothers moment. The mini 4-pound (1.8-kilogram) copter named Ingenuity, in fact, carried a bit of wing fabric from the 1903 Wright Flyer, which made similar history at Kitty Hawk, North Carolina.

“We can now say that human beings have flown a rotorcraft on another planet,” project manager MiMi Aung announced to her team.Flight controllers in California confirmed Ingenuity’s brief hop after receiving data via the Perseverance rover, which stood watch more than 200 feet (65 meters) away. Ingenuity hitched a ride to Mars on Perseverance, clinging to the rover’s belly upon their arrival in an ancient river delta in February.

ADVERTISEMENTThe $85 million helicopter demo was considered high risk, yet high reward.“Each world gets only one first flight,” project manager MiMi Aung noted earlier this month. Speaking on a NASA webcast early Monday, she called it the “ultimate dream.”

Aung and her team had to wait more than three excruciating hours before learning whether the pre-programmed flight had succeeded 178 million miles (287 million kilometers) away. Adding to their anxiety: A software error prevented the helicopter from lifting off a week earlier and had engineers scrambling to come up with a fix.

Applause, cheers and laughter erupted in the operations center when success was finally declared. There was even more when the first black and white photo appeared on the screens, showing Ingenuity’s shadow as it hovered above the surface of Mars. Next came the stunning color images of the helicopter descending back to the surface, taken by Perseverance, resulting in even more applause.

Details were initially sparse, but NASA had been aiming for a 40-second flight. The helicopter was supposed to rise 10 feet (3 meters), hover for up to 30 seconds, then pivot toward the rover and land close to where it took off.To accomplish all that, the helicopter’s twin, counter-rotating rotor blades needed to spin at 2,500 revolutions per minute — five times faster than on Earth. With an atmosphere just 1 percent the thickness of Earth’s, engineers had to build a helicopter light enough — with blades spinning fast enough — to generate this otherworldy lift. At the same time, it had to be sturdy enough to withstand the Martian wind and extreme cold.

More than six years in the making, Ingenuity is a barebones 1.6 feet (0.5 meters) tall, a spindly four-legged chopper. Its fuselage, containing all the batteries, heaters and sensors, is the size of a tissue box. The carbon-fiber, foam-filled rotors are the biggest pieces: Each pair stretches 4 feet (1.2 meters) tip to tip.

The helicopter is topped with a solar panel for recharging the batteries, crucial for its survival during the minus-130 degree Fahrenheit (minus-90 degree-Celsius) Martian nights.NASA chose a flat, relatively rock-free patch for Ingenuity’s airfield, measuring 33 feet by 33 feet (10 meters by 10 meters). It turned out to be less than 100 feet (30 meters) from the original landing site in Jezero Crater. The helicopter was released from the rover onto the airfield on April 3. Flight commands were sent Sunday, after controllers sent up a software correction for the rotor blade spin-up.

The little chopper with a giant job attracted attention from around the world, from the moment it launched with Perseverance last July until now. Even Arnold Schwarzenegger joined in the fun, rooting for Ingenuity over the weekend via Twitter. “Get to the chopper!” he shouted, re-enacting a line from his 1987 sci-fi film “Predator.”

Up to five helicopter flights are planned, each one increasingly ambitious. If successful, the demo could lead the way to a fleet of Martian drones in decades to come, providing aerial views, transporting packages and serving as scouts for astronauts. High-altitude helicopters here on Earth could also benefit — imagine choppers easily navigating the Himalayas.

Ingenuity’s team has until the beginning of May to complete the test flights. That’s because the rover needs to get on with its main mission: collecting rock samples that could hold evidence of past Martian life, for return to Earth a decade from now.

Until then, Perseverance will keep watch over Ingenuity. Flight engineers affectionately call them Percy and Ginny. “Big sister’s watching,” said Malin Space Science Systems’ Elsa Jensen, the rover’s lead camera operator.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

Biden's address to Congress: Live fact check and updates

President Biden will deliver a prime-time speech to a joint session of Congress as he prepares to mark 100 days in office. Follow here for the latest.

That’s a big statement.... Why do many downers in the comments can any of you do this? Good thing is NASA scientists still believe in God. ScottMPatterson Wouldn’t it have been great to spend all that money on the homeless or gun violence. congratulations NASA I’m a bit surprised that Mars’s atmosphere is sufficient to allow enough lift to be generated for rotary wing flight.

Important thread about batteries and CO2: Congratulations MiMi Aung and team at JPL ingenuityhelicopter YouTube still can’t play videos if you aren’t in the app. This is the correct planet for helicopters. Attn: UPS. Awesome!

SethRorabaugh Video or it didn’t happen... Any signs of intelligence? We’re running out here. FINALLY...The NASA experimental chopper in flight on Mars... Congratulations to NASA and especially NASAJPL on an amazing achievement - the first powered flight on another world with the Ingenuity MarsHelicopter! Fantastic!
