NASA’s Mars Helicopter Flies Once more and Will get a New Mission

Ingenuity, NASA’s little Mars helicopter that would, will get to fly some extra.

The small flying robotic made historical past every week and a half in the past as the primary powered plane to take off on one other world. On Friday, its fourth flight went farther and sooner than ever earlier than.

That wasn’t the one excellent news NASA had in regards to the helicopter on Friday.

In a information convention earlier within the day, the area company introduced that it was extending Ingenuity’s life by one other 30 Martian days, bringing the mission into a brand new part. Now that Ingenuity’s engineers have demonstrated that flying within the skinny air of Mars is feasible, they are going to discover how it may be used as an aerial scout for its bigger robotic companion, the Perseverance rover.

“It’s like Ingenuity is graduating from the tech demo part,” MiMi Aung, the mission supervisor of Ingenuity, mentioned throughout a information convention on Friday.

Beforehand, it had appeared as if the helicopter’s service life was rapidly drawing to a detailed. The 30 Martian days that had been allotted for take a look at flights of Ingenuity had been to expire subsequent week, and the plans had been to then abandon it, by no means to fly once more.

Ingenuity — simply 1.6 ft tall, 4 kilos in weight — is an $85 million add-on to Perseverance, NASA’s newest $2.7 billion rover, which landed on Mars in February. The helicopter is the primary to fly like an airplane or a helicopter on one other world.

The extension of Ingenuity’s flights displays not solely the success of the helicopter but additionally the will of planetary scientists for Perseverance to discover its present environment, near the place it landed in February, as an alternative of instantly driving towards an historic, dried-up river delta to search for indicators of previous Martian life.

On the fourth flight, Ingenuity used its digital camera to seek for a brand new base for future flights. On its fifth flight, it would make a one-way journey to the brand new spot. From there, it would conduct maybe one or two extra flights in Could.

Ms. Aung mentioned the helicopter might carry out reconnaissance to assist plan the place Perseverance will drive, take photos of areas too rugged for the rover to drive to and produce stereo pictures to map the elevations of the Martian panorama.

“The teachings discovered from that train will profit future missions with the aerial platforms tremendously,” she mentioned.

On Friday, Ingenuity lifted off through the center of the Martian day — on Earth, it was 10:49 a.m. Japanese time. After reaching an altitude of 16 ft, it headed south for 436 ft, flying over rocks, sand ripples and small craters. It hovered, took photos with its shade digital camera after which flew again to its place to begin, which NASA has named Wright Brothers Discipline.

The flight lined greater than twice the gap of the earlier journey 5 days earlier. This time Ingenuity additionally flew for an extended interval — 117 seconds in contrast with 80 seconds on the third flight — and sooner, reaching a high velocity of 8 miles per hour.

The success adopted an aborted flight try on Thursday. The trigger was a recurrence of an issue encountered earlier this month.

Throughout a take a look at on April 9 to spin the helicopter’s rotors to full velocity with out taking off, the start-up actions took longer than anticipated, and Ingenuity’s computer systems as an alternative shut the motors down as an alternative of getting into “flight mode.”

Throughout every week of troubleshooting, engineers got here up with a software program repair however determined to not set up it on Ingenuity due to the small however attainable likelihood {that a} bug within the new software program might trigger even greater issues, simply as upgrading the working system of your pc could cause the software program to crash.

The stakes are even increased when the pc is on one other planet 187 million miles away.

The engineers as an alternative opted for a less complicated repair: leaving the software program on Ingenuity untouched however adjusting the instructions despatched from Earth to Mars. That largely eradicated the problem, but it surely was not an ideal resolution. Testing on Earth confirmed that timing error nonetheless occurred 15 p.c of the time.

However the engineers additionally knew that if the error recurred, they may simply strive once more the next day, and the second try would most definitely succeed. That’s precisely what occurred on Friday.

After Ingenuity continues to function and show helpful, NASA might proceed to increase its life.

Ms. Aung and Bob Balaram, the chief engineer of Ingenuity, mentioned that the helicopter was designed to final solely 30 Martian days and that they may not say how lengthy it will stay in working situation. However Dr. Balaram additionally mentioned the lifetime of Ingenuity was not intrinsically restricted. The helicopter recharges its batteries by photo voltaic panels, so it won’t run out of gasoline, as an illustration.

A high velocity of 8 miles per hour could not appear notably quick, however the robotic helicopter has to fly over an alien panorama with no assist from the engineers on Earth. It makes use of a down-looking digital camera to map the panorama beneath, and if it flew too quick, it might lose observe of the place it was and maybe crash.

Nonetheless, Ingenuity has not flown any increased than the 16 ft of the final three flights, despite the fact that its two four-foot-wide counter-rotating blades generate sufficient carry to go increased off the bottom. That’s largely a limitation of its altimeter, which measures the peak by bouncing a laser off the bottom and noting the time for the mirrored gentle to return to the sensor.

Dr. Balaram mentioned the 16-foot altitude was a “candy spot” that gives good decision for the photographs used for navigation.

“I wouldn’t be stunned if at some explicit location we’re requested to go to a better vantage level,” Dr. Balaram mentioned. The helicopter might go as much as 32 ft or so with out inflicting issues for the altimeter and “present some panoramic-type imagery that may be helpful to the rover operators or the scientists.”
