When the Mars landing day comes, there's concern in NASA

CAPE CANAVERAL, Fla – A six-month journey by a NASA spaceship to Mars approached the dramatic grand finale of scientists and engineers in the hope of a soft and gentle landing on the plain red plains.

The InSight landlord aimed to reduce the afternoon as a concern built between those involved in the $ 1 billion international effort.

A dangerous landing along the Mars atmosphere in InSight, after a trip of 300 million miles (482 million kilometers), the stomach fractures and nerves max. Although he was a former professional on this subject, NASA tried to land on Mars six years ago.

Mars' mysterious insides & # 39; The robot geologist – designed to explore – Mars goes mad with his atmosphere, takes out a parachute, landing engines and hopefully, in three minutes on fire, he must go from zero to zero in 12,300 miles (19,800 kph) in six minutes.

InSight's leading scientist, Bruce Banerdt, said, "The landing on Mars is one of the most challenging jobs people need to do on planet discoveries." "It's a very difficult thing, it's a very dangerous thing to have something quite uncomfortable every time something might go wrong."

The success rate of the world in Mars is 40% and it is considered as a flight and landing by each country, to the USA, Russia and other countries extending to the 1960s. .

However, the United States in the last forty years, seven successful Mars landing took off. Just one unsuccessful drop, an enviable record. No other country was able to establish and operate a spacecraft on a dusty red surface.

InSight can give NASA the eighth victory.

He hopes the Inisight team is as flat as a parking spot in Kansas, shooting for the Elysium Planitia, a plain near the Martian equator. This is not a rock gathering trip. Instead, the 800-pound fixed-weight fixed terrain will use the 6-meter (1.8-meter) robot arm to place a mechanical molar and seismometer on the ground.

While the ultra-high-tech seismometer listens for possible marls, the self-beating mole will go down 16 meters (5 meters) to measure the inner temperature of the planet. Nothing like this was attempted at about 100 million miles (160 million kilometers) in our smaller neighbor neighbor.

From the spacecraft to the real Mars surface, no robotic experiments were performed. No landing went deeper than a few inches, and no seismometry on Mars worked.

By examining the darkest and darkest interior of Mars – its oldest days are still going on – scientists hope to create 3D images of the rocky planets of our solar system that could reveal how they were formed over 4.5 billion years ago and why they were so different. One of the big questions was what made the Earth so welcoming.

Mars once had rivers and lakes flowing; The deltas and lakes are now dry and the planets are cold. Venus is a furnace due to its thick, warm keeping atmosphere. Mercury, which is the closest to the sun, has a favorably cooked surface.

According to Banerdt, the planetary knowledge derived from InSight's two-year operation can be cast into rocky worlds beyond our solar system. Findings on Mars can help explain the kind of conditions on so-called extrinsic planets, and how they fit into the story we're trying to figure out how the planets are formed.

InSight & # 39; s focus is on planet building blocks and has no capacity to detect life. Will stay for future rovers. For example, NASA's Mars 2020 mission will collect rocks for the final return that could hold evidence of the old life.

Because NASA has been a long time since the beginning of last March – the curious rover in 2012 – the Mars mania not only influences spaces and sciences, but also everyday people.

The following parties are planned for the coast from coast to coast in France, where the seismometer of InSight is designed and built, as well as in museums, planetariums and libraries. The giant NASDAQ screen in Times Square, New York, will begin broadcasting NASA Television an hour before InSight's 3 o'clock. EST is set; The National Air and Space Museum will also have the Udvar-Hazy Center in Chantilly, Virginia, and the Denver Museum of Nature and Science. The InSight spacecraft was built by Lockheed Martin near Denver.

But the real action, at least in the World, will host the flight control team of InSight in NASA's Jet Propulsion Laboratory in Pasadena, California. NASA offers a 360-degree exclusive online broadcast from within the control center.

The check confirmation may take minutes or hours. At least, there's an eight-minute communication delay between Mars and the Earth.

A pair of briefcases, separated from InSight, will attempt to transmit radio signals to the Earth since the revival in May, with a lag time of less than nine minutes. These experimental CubeSats will pass the red planet incessantly. Signals can also travel from InSight to radio telescopes in West Virginia and Germany. It can take longer than NASA's Mars orbit.

Project manager Tom Hoffman said on Sunday that he is trying his best to stay outdoors as the clocks go down. When InSight returns home from the surface of Mars, she expects her three young grandchildren to act like crazy and scream as she does at the Thanksgiving dinner.

He said, "I will release my 4-year-old child inside me, so be careful."
