When NASA scientists have been planning the Mars Perseverance mission, they determined to attempt one thing new: As a substitute of simply sending a rover, they’d additionally ship up a small helicopter. Though initially meant as a easy expertise demonstration, the plane Ingenuity has far exceeded expectations.
“It did such an excellent job in actual fact that regardless that we initially have been meant to fly solely as much as 5 instances on Mars, we acquired 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 throughout 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 may additional discover and even pattern the Martian atmosphere and the way NASA’s Dragonfly mission to Saturn’s moon Titan will make the most of a helicopter to assist us examine a completely totally different world.

Though its first flight was an indication that lasted solely 39 seconds, Ingenuity has no longer 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 world. It additionally photographed Perseverance’s touchdown gear to provide engineers a helpful have a look at their work on the gear after it had been used.
In the course of the briefing, Grip described how Ingenuity crew members made a pilot’s logbook for the helicopter earlier than touchdown on Mars and added a lot of additional 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 accumulate pattern tubes from the Martian floor. This Mars Sample Return Pattern Restoration Helicopter could be primarily based on Ingenuity’s design however would boast wheels for navigating on the bottom, in addition to a robotic arm.
The upgrades would enable 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 crew lead for Ingenuity and the supervisor for the brand new pattern restoration helicopters mission, throughout the briefing.
“We’re largely leveraging all the wonderful classes realized — that we now have realized and can proceed to be taught with ingenuity over the past yr and a half,” he mentioned.
Mars is not the one world NASA will discover with an plane. NASA’s Dragonfly mission, presently 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 strain of Earth, Titan is a particularly straightforward place to fly. Actually, it is a lot simpler to fly on Titan than Mars that Dragonfly is concerning the measurement of the Perseverance rover — like a small SUV. In distinction, Ingenuity is just about 1.6 toes (0.5 meters) tall and 6 inches (15 centimeters) large (not counting its blades), nearer to the scale of small remote-controlled drones on Earth.
Scientists need 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 throughout 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 ample carbon-rich chemistry, like that present in life on Earth.
Finding out Titan will give scientists a have a look at this acquainted chemistry in a very totally different context, enabling them to check whether or not sure circumstances are liveable and may need led to life. To do that, Dragonfly can be outfitted with scientific devices together with spectrometers, a drill for gathering samples, geophysics and meteorology sensors and a digital camera.
“Essentially, Dragonfly is a chemistry mission,” Turtle mentioned. “Titan has been doing the type of chemistry experiments we won’t do right here on Earth, as a result of we do not have thousands and thousands of years within the laboratory to do them. So Titan has been doing these for us, and Dragonfly is designed to select up the outcomes of these experiments.”
Sooner or later, plane may play different import roles for planetary exploration. Helicopters may take samples from areas with out leaving the type of observe marks and disturbances {that a} rover would, which could possibly 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 scale 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 yr and a half in the past.”
