NASA’s Mars Ingenuity Helicopter Completes Second Flight

NASA’s engineers already made historical past on Monday with the 39.1-second flight of Ingenuity, a small helicopter, within the skinny environment on Mars. On Thursday, they added to their success when the experimental car flew increased, longer and riskier.

At 5:33 a.m. Eastern time — it was 12:33 p.m. in Jezero crater on Mars — Ingenuity autonomously lifted once more off the crimson floor of Mars, kicking up a cloud of mud because it ascended. It reached a peak of 16 toes, tilted itself by 5 levels to maneuver seven toes sideways, hovered and turned to level its shade digicam in a number of instructions, then returned to its start line to land.

This flight lasted 51.9 seconds.

“It sounds simple, but there are many unknowns regarding how to fly a helicopter on Mars,” Håvard Grip, Ingenuity’s chief pilot, mentioned in a NASA news release. “That’s why we’re here — to make these unknowns known.”

The Ingenuity helicopter is a demonstration of a new aerial capability that NASA could use in future years, and it was added to Perseverance, a rover that cost billions of dollars to send to Mars to search for signs of extinct microbial life. Although the small rotorcraft cost a fraction of the mission that carried it — $85 million — it packs sophisticated computer hardware and software. And the project required engineers at NASA to devise solutions to major engineering problems.

Most difficult among them was how to make a helicopter fly in 1/100th the air that’s found at Earth’s surface, without which it is difficult to fly. The team at NASA’s Jet Propulsion Laboratory that built Ingenuity overcame these problems with ultralight materials that could spin at roughly 2,400 rotations per minute.

In its first flight on Monday, Ingenuity rose to a height of 10 feet before pivoting 90 degrees and landing almost exactly where it started. But the short hop was the first powered flight like an airplane or a helicopter on another world, and extended NASA’s list of distinctions on Mars.

It also reinforced how the solar system’s mysteries can be unlocked with modes of transportation beyond robotic surface rovers and orbiting satellites. Engineers on Earth may be more inspired to explore the potential of other unconventional spacecraft like a robotic blimp to study the clouds of Venus or a submarine drone to dive into the oceans of icy moons like Europa.
