When NASA scientists had been planning the Mars Perseverance mission, they determined to strive one thing new: As an alternative of simply sending a rover, they’d additionally ship up a small helicopter. Though initially meant as a easy know-how demonstration, the plane Ingenuity has far exceeded expectations.
“It did such a superb job in reality that regardless that we initially had been meant to fly solely as much as 5 occasions on Mars, we received a brand new mission,” Håvard Grip, an engineer at NASA’s Jet Propulsion Laboratory (JPL) in California who’s the aerodynamics and flight management lead and the chief pilot for the Ingenuity helicopter, mentioned throughout a information convention in the course of the American Geophysical Union Fall Assembly being held this week in Chicago and just about. Ingenuity would now assist scout forward for the Perseverance rover, scoping out the panorama from the air.
Actually, Ingenuity has been so profitable that scientists are already gearing up to make use of successor helicopters to discover Mars and past, together with how future helicopters might additional discover and even pattern the Martian setting and the way NASA’s Dragonfly mission to Saturn’s moon Titan will make the most of a helicopter to assist us research a wholly completely different world.

Though its first flight was an illustration that lasted solely 39 seconds, Ingenuity has not solely scouted for Perseverance, but in addition taken detailed pictures of a Martian outcrop, serving to scientists to create a 3D mannequin to check the realm. It additionally photographed Perseverance’s touchdown gear to offer engineers a beneficial take a look at their work on the gear after it had been used.
Through the briefing, Grip described how Ingenuity staff members made a pilot’s logbook for the helicopter earlier than touchdown on Mars and added plenty of further pages as a result of they thought a five-page logbook would look foolish.
“However guess what? We’re out of pages,” he mentioned, holding up the e-book. “As of two days in the past, Ingenuity made its thirty sixth flight, and there are 36 pages in right here.”
NASA scientists are aiming to construct on Ingenuity’s success by growing an plane that may gather pattern tubes from the Martian floor. This Mars Sample Return Pattern Restoration Helicopter could be based mostly on Ingenuity’s design however would boast wheels for navigating on the bottom, in addition to a robotic arm.
The upgrades would permit two of the brand new helicopters to gather pattern tubes, serving as a backup for Perseverance, which is supposed to ship the tubes to the sample-return lander, mentioned Teddy Tzanetos, who’s an engineer at JPL, the engineering staff lead for Ingenuity and the supervisor for the brand new pattern restoration helicopters mission, in the course of the briefing.
“We’re largely leveraging the entire wonderful classes discovered — that we now have discovered and can proceed to study with ingenuity over the past 12 months and a half,” he mentioned.
Mars is not the one world NASA will discover with an plane. NASA’s Dragonfly mission, at present scheduled for a 2027 launch, will use a rotorcraft to discover Saturn‘s icy moon Titan. The one moon within the solar system with an environment, Titan is right for aerial exploration: as a result of it has a weaker gravity and half once more the atmospheric stress of Earth, Titan is an especially simple place to fly. Actually, it is a lot simpler to fly on Titan than Mars that Dragonfly is concerning the dimension of the Perseverance rover — like a small SUV. In distinction, Ingenuity is barely about 1.6 ft (0.5 meters) tall and 6 inches (15 centimeters) vast (not counting its blades), nearer to the dimensions of small remote-controlled drones on Earth.
Scientists wish to go to Titan for a number of causes, Elizabeth Turtle, a planetary scientist on the Johns Hopkins Utilized Physics Laboratory in Maryland and the principal investigator for the Dragonfly mission, mentioned in the course of the information convention. Not solely does Titan have a water-ice crust and seas of liquid methane paying homage to water on Earth, Turtle mentioned, it additionally has considerable carbon-rich chemistry, like that present in life on Earth.
Finding out Titan will give scientists a take a look at this acquainted chemistry in a completely completely different context, enabling them to check whether or not sure situations are liveable and may need led to life. To do that, Dragonfly might be outfitted with scientific devices together with spectrometers, a drill for gathering samples, geophysics and meteorology sensors and a digicam.
“Essentially, Dragonfly is a chemistry mission,” Turtle mentioned. “Titan has been doing the sort of chemistry experiments we will not do right here on Earth, as a result of we do not have hundreds of thousands of years within the laboratory to do them. So Titan has been doing these for us, and Dragonfly is designed to choose up the outcomes of these experiments.”
Sooner or later, plane might play different import roles for planetary exploration. Helicopters might take samples from areas with out leaving the form of observe marks and disturbances {that a} rover would, which might be particularly necessary in areas scientists name “biologically delicate.” NASA scientists are additionally growing a design for a future Mars Science Helicopter, which like Dragonfly could be the dimensions of Perseverance and would have the ability to carry heavier samples and scientific devices.
“My private dream is one day we’ll have astronauts at Mars and there will be fleets of automobiles zipping round serving to the primary people there with easy and complex duties,” Tzanetos mentioned. “However it began with that first 39-second flight that we did a couple of 12 months and a half in the past.”
