NASA’s Mars Helicopter Flies Again and Gets a New Mission

Ingenuity, NASA’s little Mars helicopter that could, will get to fly some more.

The small flying robot made history a week and a half ago as the first powered aircraft to take off on another world. On Friday, its fourth flight went farther and faster than ever before.اضافة اعلان

That wasn’t the only good news NASA had about the helicopter Friday.

In a news conference earlier in the day, the space agency announced that it was extending Ingenuity’s life by another 30 Martian days, bringing the mission into a new phase. Now that Ingenuity’s engineers have demonstrated that flying in the thin air of Mars is possible, they will explore how it can be used as an aerial scout for its larger robotic companion, the Perseverance rover.

“It’s like Ingenuity is graduating from the tech demo phase,” MiMi Aung, the project manager of Ingenuity, said during a news conference Friday.

Previously, it had seemed as though the helicopter’s service life was quickly drawing to a close. The 30 Martian days that had been allocated for test flights of Ingenuity were to run out next week, and the plans were to then abandon it.

Ingenuity — just 1.6 feet tall and 4 pounds in weight — is an $85 million add-on to Perseverance, NASA’s latest $2.7 billion rover, which landed on Mars in February. The helicopter is the first to fly like an airplane or a helicopter on another world.

The extension of Ingenuity’s flights reflects not only the success of the helicopter but also the desire of planetary scientists for Perseverance to explore its current surroundings, close to where it landed in February, instead of immediately driving toward an ancient, dried-up river delta to look for signs of past Martian life.

On the fourth flight, Ingenuity used its camera to search for a new base for future flights. On its fifth flight, it will make a one-way trip to the new spot. From there, it will conduct perhaps one or two more flights in May.

Aung said the helicopter could perform reconnaissance to help plan where Perseverance will drive, take pictures of areas too rugged for the rover to drive to and produce stereo images to map the elevations of the Martian landscape.

“The lessons learned from that exercise will benefit future missions with the aerial platforms tremendously,” she said.

On Friday, Ingenuity lifted off during the middle of the Martian day — on Earth, it was 10:49 a.m. Eastern time. After reaching an altitude of 16 feet, it headed south for 436 feet, flying over rocks, sand ripples and small craters. It hovered, took pictures with its color camera and then flew back to its starting point, which NASA has named Wright Brothers Field.

The flight covered more than twice the distance of the previous trip five days earlier. This time Ingenuity also flew for a longer period — 117 seconds compared with 80 seconds on the third flight — and faster, reaching a top speed of 8 mph.

The success followed an aborted flight attempt Thursday. The cause was a recurrence of a problem encountered earlier.
