NASA will soon try to fly a helicopter over Mars: “It’s really like the Wright brothers’ moment”



NASA boosts start of anti-aircraft spacecraft with eight successful landings on Mars Perseverance. Determined to take off this week, the latest rover is taking a helicopter on another world’s test flight.

The four-pound Ingenuity helicopter will travel to Mars, clogging the rover’s belly and trying to fly solo a few months after landing. When it falls to the surface of Mars, ingenuity will begin as a tiny bird, soaring 10 feet into the planet’s ultra-thin atmosphere and flying forward to 6 feet. With each attempt you will try to climb a little higher and further.

“It’s really like the Wright brothers’ moment,” said project manager MiMi Aung. Before the rover moves to more urgent geological work, it has to compress as many helicopter hops as possible in one month. The future could be seen by a new generation of helicopters looking for astronauts or even robots from distant Mars territory.

Perseverance sports the latest landing technology, as well as the most cameras and microphones ever assembled to capture the images and sounds of Mars. Its super-disinfected return tubes – for rocks that may have evidence of Mars life in the past – are the cleanest items ever occupied in space.

This summer’s third and final mission to Mars – after the United Arab Emirates’ orbit of hope and China’s “Search for Heaven’s Truth” orbiter-rover combo – begins with a launch scheduled for Thursday morning from Cape Canaveral. Like other spacecraft, perseverance on the red planet is expected to reach next February after seven months and more than 300 million miles of travel.

Here’s a look at perseverance:

Perseverance against curiosity

The six-wheel-drive, car-sized Perseverance, is a replica of NASA’s Curiosity rover that has been riding on Mars since 2012, but with more upgrades and a larger share. Its 7-foot (2-meter) robot handle is stronger and has a larger drill for collecting rock samples. It has 23 cameras, most of which are color, and two more – an ingenious, hitchhiking helicopter. The cameras will give a first look at the parachute wave opened at Mars, with two microphones allowing Earthlings to be heard for the first time. Once inhabited by a river delta and a lake, Lake Crater is NASA’s most risky landing site for NASA due to boulders and rocks that are expected to be avoided by the spacecraft’s self-navigation system. Perseverance also has more opportunities to drive independently, so it can involve more than “Curiosity”. The upgrades increase the cost of the mission: nearly $ 3 billion.

Sampling

Perseverance will drill into the rocks, most likely with signs of ancient life, and leaving the collection on the ground to await the future rover. There are forty-three tubes on this rover, each of which is thoroughly washed and baked to remove terrestrial microbes. NASA wants to prevent organic molecules from entering Earth from returning samples from Mars. Each tube can contain half an ounce (15 grams) of primary samples, and the goal is to collect about 0.5 pounds (0.5 kilograms) to return to Earth. NASA expects 2026 Launch a collection mission and by 2031. – return the samples to Earth as soon as possible.

Human benefits

In addition to the helicopter, Perseverance conducts other experiments that could be of direct benefit to astronauts on Mars. A device the size of a car battery will convert atmospheric carbon dioxide into oxygen, a necessary component of rocket propellant fuel and the respiratory system. Another instrument, which includes rocks with lasers to identify organic molecules and minerals, carries samples of cosmic matter. NASA wants to see how the fabric withstands the harsh environment of Mars. According to NASA, it will be 2030 at best, before the astronauts sail to Mars.

Great passengers

A couple of Mars meteorites are finally traveling home or at least using their strips as calibration targets with laser-firing instruments on board the perseverance. Other cool passengers include silicon chips with the names of nearly 11 million people registered, as well as a small plate showing the Earth and Mars on opposite sides of the sun with the Morse code message “explore as one” wrapped in sunlight. There is also a medical tribute board on the front lines of the pandemic. The coronavirus prevents hundreds of scientists and other team members from going to Cape Canaveral to run.

“Seven Minutes of Terror”

NASA scientists and engineers call it the “Seven Minutes of Terror”: a tense 420-second compressive breath as Mars Rover takes over his destiny and tries to land autonomously on a red planet. This term is defined as the period of time that elapses from the entry of the rover landing capsule into the atmosphere of Mars to the touch of the planet’s surface. During that time, the rover relied on pre-programmed information rather than engineers on people controlled by NASA.

“It’s nervous,” said Matt Wallace, NASA’s deputy project manager. said “60 minutes”. “It’s really the most difficult part of the mission.”
