NASA Lands Ingenuity, the ever-present Mars helicopter


This very early in the morning, NASA flew a small drone helicopter that took its last vehicle to Mars, the first human-controlled and manned flight to another planet. The invention stuck to the landing and the space engineers are stoke.

“We’re happy, of course,” said Matthew Golomb, NASA’s chief research scientist at NASA’s Jet Propulsion Lab, shortly after the success of the invention team’s call to WIRED. The data that went into JPL computers on Monday morning is “nominal,” NASA said, adding that it is the best case scenario. “Every time you land a spaceship, it’s a pretty good moment,” Golomb said.

According to intelligence, it rose one meter per second to three meters — about 10 meters from Mars. The helicopter hung as uniformly as its state-of-the-art electronics allowed, and then landed where it was 40 seconds earlier. Then Invention sent a message they had been looking for for almost a decade to Earth engineers: mission accomplished. The walking drone has sent a black-and-white video of its shadow and the Perseverance rover’s high-resolution camera has taken shots of the flight and landing from a distance.

“Now we can say that humans have turned to another planet,” project director MiMi Aung told his team after the flight that he was in front of a giant wall art that read DARE MIGHTY THINGS. has been engine drop coded in parachute.

The machines sent by humanity to Mars have become more and more sophisticated since Sojourner’s first vehicle was launched in 1997. This robot put the first wheels on Mars and its cousins, Spirit, Opportunity and Curiosity, took them to the science experiments department. But Sustainability – the largest in the range, which landed in February“He’s flying around the Red Planet with a helicopter in his stomach.” Asthma is NASA’s first attempt to fly a drone on another planet. The space agency and the contractors involved in its design want to learn lessons from designing larger prospects from flight data for future missions.

The invention looks like a bright four-legged mosquito, rocking two helicopter blades and a solar panel on its head. It is about two feet high and its 15-inch legs keep it upright from sharp foreign ground. The blades of four-foot-wide carbon fiber rotors rotate very quickly to carry the body Nothing else each item is enough to store the battery, sensors, cameras, and brain that works in concert.

Flying to Mars is different from flying to Earth. Gravity is 62 percent weaker there, but the atmosphere is 99 percent thinner and provides much less lift. A helicopter would be like flying at an altitude of 100,000 meters on Earth, where the record for high flights is less than 41,000 feet for a helicopter and 85,000 for an aircraft. The blades of the rotors of the intellect rotate at a speed of 2,537 revolutions per minute, five times faster than those used by helicopter blades on Earth.

Due to the thin atmosphere, the daily temperatures of Mars can rise by more than 150 degrees, which makes the density of the air very variable. Engineers had to consider this unreliable air cushion. “At sea level on land, the pressure doesn’t change that much,” said Ben Pipenberg, an aeromechanical engineer at AeroVironment. The California airline has been working with JPL since 2013 to bring the idea of ​​the helicopter to life. Mars, however, continues: “From our current operating point, we can raise or lower the operating pressure by about 30 to 40 percent and still fly.”

Each part of the helicopter is designed to maximize function and reduce weight. The paddles weigh a total of 70 grams, less than a deck of cards. The entire $ 85 million drone weighs about four pounds – less than a liter of ice cream.
