Mars is sometimes called the “Pink Planet” due to the rusty, reddish-orange sandscape blanketing the planet. That comes into sharp focus in our first colour photograph snapped by the Mars Ingenuity helicopter.
That was taken about 17 toes above the bottom. You’ll be able to clearly see the sandy red-orange Martian floor. And if you happen to take a look at the underside of the picture, you may clearly see Ingenuity’s shadow, with two of its spindly legs visibly jutting out from it is rectangular physique.
These patterns within the floor that appear like tracks are in actual fact… tracks left by the Perseverance rover, the remote-operated analysis car that carried Ingenuity safely to Mars. As soon as it deposited its flying robotic pal the Perseverance headed off to a brand new location, first to watch the helicopter for a month after which to proceed with its different duties.
This is a more in-depth take a look at these tracks.
Technically, you are one thing historic within the above pictures. This is not simply the primary colour photograph that Mars Ingenuity despatched again dwelling; it is also “the primary colour picture of the Martian floor taken by an aerial car whereas it was aloft,” says NASA. That is a much bigger deal than it would sound like initially.
The entire goal of Ingenuity’s presence on Mars is to check NASA’s skill to function an aerial car within the Martian environment. We’re at present investigating the planet with the assistance of drones like Ingenuity and Perseverance, however in some unspecified time in the future the plan is to get people on the market as properly, together with extra elaborate autos.
So it is vital to know how aerodynamics work within the Martian environment, particularly since attending to Mars is not a easy course of. (The journey that introduced Perseverance and Ingenuity to the planet was a seven-month journey.) One mistaken resolution on Earth may set again analysis for a 12 months or extra.
That is additionally why NASA is utilizing the autos to conduct different exams, such as exploring the viability of drawing oxygen out of the Martian atmosphere. Human guests will clearly want a prepared provide of breathable air if they’ll spend an considerable period of time testing the planet, so checking to see if and the way that is attainable now, earlier than folks get there, is important.
The photograph above was snapped throughout Ingenuity’s second flight, which occurred on April 22. Its inaugural flight went off with no hitch just some days earlier, on April 19. Now NASA is already looking forward to the subsequent one: Ingenuity will take to the Martian “skies” once more — it actually would not fly that prime — on the morning of April 25.
The concept with these exams is to maintain ramping issues up, so anticipate a much bigger exhibiting this time round. For the first flight, Ingenuity spent about 40 seconds off the ground, hovering in place at a top of roughly 10 toes. The second check went larger, near 17 toes, and noticed the helicopter transfer about six and a half toes to the east, then again. It spent virtually a minute within the air and made three turns throughout that point.
NASA would not anticipate the third flight to take Ingenuity any larger, however it is going to transfer sooner — going from roughly 1 mile-per-hour to 4.5 miles-per-hour — and journey an extended distance. The plan is for Ingenuity to go a bit greater than 160 toes to the north then return to its place to begin, named “Wright Brothers Area,” and land. Whole flight time will come near a minute and a half.
All of those particulars might not sound significantly spectacular, however NASA puts them into context with some historical perspective within the write-up from Håvard Grip, chief pilot for the Mars Ingenuity Helicopter on the Jet Propulsion Laboratory.
“Whereas [the 330-foot flight distance for test three] might not look like rather a lot, contemplate that we by no means moved laterally greater than about two-pencil lengths once we flight-tested within the vacuum chamber right here on Earth,” Grip writes. “And whereas the 4 meters of lateral motion in Flight Two (2 meters out after which 2 meters again) was nice, offering a lot of terrific information, it was nonetheless solely 4 meters. As such, Flight Three is an enormous step, one by which Ingenuity will start to expertise freedom within the sky.”
You are seeing the fruits of years price of labor taking part in out in actual time as these exams unfold. Throughout the 30-day interval beginning with its first flight, and barring any technical difficulties or gear failures, NASA hopes to conduct 5 flight exams in complete utilizing Ingenuity.
