Washington, United States:
It was only supposed to fly 5 occasions. And but NASA’s helicopter on Mars, Ingenuity, has completed 12 flights and it is not prepared to retire.
Given its gorgeous and unexpected achievement, the US space agency has extended Ingenuity’s mission indefinitely.
The tiny helicopter has grow to be the normal travel companion of the rover Perseverance, whose core mission is to seek indicators of ancient life on Mars.
“Everything is working so well,” stated Josh Ravich, the head of Ingenuity’s mechanical engineering group. “We’re doing better on the surface than we had expected.”
Hundreds of individuals contributed to the project, even though only about a dozen at the moment retain day-to-day roles.
Ravich joined the group 5 years ago.
“When I got the opportunity to come work on the helicopter project, I think I had the same reaction as anybody else: ‘Is that even possible?'”
His initial doubts had been understandable: The air on Mars has a density equivalent to only one % that of Earth’s atmosphere. By way of comparison, flying a helicopter on Mars would be like flying one in the thin air almost 20 miles (30 kilometers) above Earth.
Nor was it simple obtaining to Mars in the 1st location. Ingenuity had to withstand the initial shock of takeoff from Earth, and then of the February 18 landing on the red planet following a seven-month voyage by way of space, strapped to the rover’s belly.
Once in its new surroundings, the tiny (4 pound, or 1.8 kilogram) copter has had to survive the glacial cold of Martian nights, drawing warmth from the solar panels that charge its batteries in the course of the day. And its flights are guided working with an array of sensors, considering the fact that the 15-minute lag in communications from Earth tends to make true-time guidance not possible.
Scouting duties
On April 19, Ingenuity carried out its maiden flight, creating history as the 1st motorized craft to fly on a further planet.
Exceeding all expectations, it has gone on to fly 11 more occasions.
“We’ve actually been able to handle winds greater than we had expected,” Ravich told AFP.
“I think by flight three we had actually accomplished all of our engineering goals … (and) got all the information we had hoped to get,” stated Ravich, who performs for NASA’s famed Jet Propulsion Laboratory (JPL), which created the helicopter.
Since then, Ingenuity has flown as higher as 39 feet (12 meters), and its last flight lasted two minutes and 49 seconds. In all, it has covered a distance of 1.6 miles.
In May, Ingenuity flew its 1st one-way mission, landing outdoors the reasonably flat “airfield” that had been very carefully chosen as its initial home.
But not all has gone smoothly. Its sixth flight brought some excitement.
After getting knocked dangerously off-balance by a malfunction affecting the photographs taken in flight to assistance it stabilize, the tiny craft was capable to recover. It landed, protected and sound, and the trouble was resolved.
Ingenuity is now getting sent out to scout the way for Perseverance, working with its higher-resolution colour camera.
The objective is twofold: to chart a path for the rover that is protected, but also which is of scientific interest, notably in geological terms.
Ken Farley, who heads Perseverance’s science group, explained how photographs taken by Ingenuity in the course of its 12th flight showed that a area dubbed South Seitha was of much less interest than scientists had hoped.
As a outcome, the rover could not be sent there.
Favorable circumstances
After more than six months on the red planet, the small drone-like craft has gained a increasing following on Earth, featured on coffee cups and T-shirts sold on the online.
What explains its longevity?
“The environment has been very cooperative so far: the temperatures, the wind, the sun, the dust in the air… It’s still very cold, but it could have been a lot worse,” stated Ravich.
In theory, the helicopter must be capable to maintain operating for some time. But the approaching Martian winter will be difficult.
NASA engineers, now armed with the information from Ingenuity’s flights, are currently working on its next-generation successors.
“Something in the 20 to 30 kilograms (range) maybe, able to carry science payloads,” stated Ravich.
Those future payloads could just include things like the rock samples collected by Perseverance.
NASA is organizing to retrieve these samples in the course of a future mission — sometime in the 2030s.
