NASA is about to land the first-ever helicopter on Mars.
The little craft, weighing in at slightly below four lbs. (1.eight kilograms) and named Ingenuity (a moniker given by Alabama scholar Vaneeza Rupani), is tucked up within the stomach of NASA’s Perseverance rover. Ingenuity, which launched final summer season on board Perseverance as a part of the company’s Mars 2020 mission, will make the primary powered flight on one other planet.
And the helicopter is ready to land at the moment (Feb. 18). The “Mars helicopter has been absolutely examined as a lot as we will on Earth,” MiMi Aung, the Ingenuity venture supervisor at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, stated in a information convention Tuesday (Feb. 16). Ingenuity will land at the moment with Perseverance, which is ready to the touch down in Mars’ Jezero Crater — an historic delta that scientists assume may maintain concrete proof of previous life on Mars.
“To see it there, getting there lastly, it is sort of surreal nonetheless,” Josh Ravich, Ingenuity’s mechanical engineering lead at JPL, informed House.com.

Now, the Mars helicopter, or “marscopter,” is not a fully-fledged transportation gadget and it is vastly completely different from helicopters we now have right here on Earth. The tiny craft is “only a know-how demonstration,” Ravich stated. “Its main aim is simply to see if we will fly on Mars — show that the know-how works.”
The day after Perseverance lands, the group “will flip [Ingenuity] on to substantiate that the well being is nice,” Aung stated. “After that, the subsequent main milestone might be when [the] Perseverance rover delivers Ingenuity to the floor of Mars.” To get to this subsequent step, the group must discover a appropriate location for the experimental flight.
“The helicopter group might be working with the rover group and the scientists to search for the suitable experimental web site for our flight experiments,” Aung stated.
After the location is chosen, the marscopter will take its inaugural flight, the primary flight by a powered craft on an alien world. That is prone to occur within the early phases of the Mars 2020 mission, and Ingenuity will possible make its first, quick flight inside the first few months of the mission, Mars 2020 programs testbed engineer Elio Morillo informed House.com.
Perseverance rover’s Mars touchdown: Everything you need to know
To get to the planet’s floor, nonetheless, the helicopter must be dropped from the rover’s stomach the place it spent its time in the course of the interplanetary journey. To make this drop, Ingenuity has to undergo what is named the Mars helicopter supply system. “It is a very intricate system that is going to take about 10 days to undergo … to drop Ingenuity to the floor,” Aung stated.
Nonetheless, Aung added, “the second that drop occurs is the second that Ingenuity has to begin working by itself in a standalone style.”
Throughout Ingenuity’s first flight, the craft will elevate up, flying about 10 ft (three meters) above the bottom. It’ll hover there for about 20 seconds, in accordance with Aung.
However the tiny Martian helicopter does not simply have the bold activity of flying on one other world, “this little four-pounder has to outlive the chilly frigid nights of Mars,” Aung stated, including that to “hold itself heat, it has to garner vitality from the solar by means of its photo voltaic panels to cost its battery. It has to speak to the [International] House Station. It has to do all of that.”
Future marscopter purposes
Now, whereas Ingenuity may simply be an exploratory know-how demonstration, “there’s a whole lot of future purposes” for the craft, Ravich stated.
As an illustration, with a automobile like Ingenuity, “you’ll be able to fly fairly far forward fairly shortly, you’ll be able to go to locations you’ll be able to’t go in any other case: up mountains, down ravines — locations that people and rovers would not actually be capable of entry,” he stated. He added that such a functionality may help future robotic missions with scouting and imaging difficult terrain, and it may even in the future be of assistance to crewed missions.
A helicopter in contrast with, for instance, rovers or future human explorers, may have “entry to locations you’ll be able to’t go in any other case,” Ravich added, specifying that Martian lava tubes may doubtlessly be extra simply explored by a helicopter than different autos, and it may try this exploration pretty shortly, or a minimum of faster than robotic floor autos like rovers.
Future crewed missions may additionally presumably be supported by autos like Ingenuity, he added.
For instance, “I am out doing Mars operations as an astronaut, I forgot my wrench again dwelling on the base. Perhaps I can ship a helicopter again to select it up for me,” he stated.
Nonetheless helicopters are used on Mars sooner or later, Ingenuity’s first flight is “a real extraterrestrial Wright Brothers second,” Thomas Zurbuchen, NASA affiliate administrator for science at NASA Headquarters, stated in the course of the information convention Feb. 16.
