The US Perseverance probe on Mars, which left Earth on July 30 last year, traveled some 466,800 km in outer space for 204 days and finally at 5:55 a.m.Korean time on the 19th. settled on the surface of Mars.
With this, the US managed to complete the global Mars exploration campaign, which began in July last year, following the United Arab Emirates (UAE) and China, and achieved a kind of beauty. In particular, the United States was the only one among them that penetrated the atmosphere of Mars and made a landing record on the surface of Mars, what is called ‘7 minutes of horror’. The United States is the only country that has successfully landed on Mars.
Around 6 am that day, an announcement of “Landing confirmed” sounded in the control room of NASA’s Jet Promotion Research Center (JPL), and cheers immediately broke out.
Acting NASA Director Steve Jurchik said in a briefing held after the landing, saying, “It’s an amazing and wonderful day.” “We are proud of the team members who have overcome the difficult environment of the novel coronavirus (COVID-19, Corona 19) infection and successfully land Percivirence on Mars, I said.
“We landed a representative of Earth on Mars, where no one has been,” said Mike Ockkins, director of NASA’s Jet Propulsion Research Center (JPL). “The Rover may discover something special in its early days on the mission.”
The percivirence entered the atmosphere of Mars at a speed of 5.5 km / s at 5:48 am on the day, and gradually diminished and attempted to land on Mars. Since it takes about 11 minutes and 20 seconds for the signal to travel from Mars to Earth, Persistence moves on its own according to a plan arranged in minutes, from entering the Martian atmosphere to descent and landing.
○ President Joe Biden “The power of science has been proven”
Foreign figures, including US President Joe Biden and French President Emmanuel Macron, also congratulated Percivierence’s landing on Twitter.
President Biden wrote on Twitter: “Congratulations to everyone and to NASA for making the historic Percivirence landing. The power of science, American ingenuity and the fact that nothing is impossible,” he wrote.

“Congratulations to NASA and all of its partners for a successful mission,” Vice President Kamala Harris said on Twitter. “Today’s historic landing will strengthen America’s spirit of patience, enhance past achievements, and pave the way for future missions.”
French President Emmanuel Macron congratulated him and looked forward to the success of Supercam, in which French scientists participated in the development. Supercam is a special camera attached to Persivirance, and researchers from the National Institute for Space Research (CNES) and the French National Center for Scientific Research (CNRS) participated in the development. “Congratulations to NASA, CNES and CNRS,” President Macron said on Twitter. “French excellence has come to Mars with Percivience”.
Congratulatory messages were also sent from space. Soichi Noguchi, an astronaut belonging to the Japan Aerospace Research and Development Organization (JAXA), who is staying at the International Space Station (ISS), left a message on Twitter around 5:00 am, “We will see the landing of Perceived on the ISS. “Upon landing on Mars,” Congratulations A flawless landing! ”
○ Percivirance, search for traces of life on Mars for about 2 years
Immediately upon arrival, Percivirence sent two images of the surface of Mars to Earth to announce its existence. Percivirence scans the surface for traces of life for 687 days, equivalent to a year on Mars, if scheduled.
First, the exploration begins around the landing point, ‘Crater example’. For example, the crater is located at 18.4 degrees north latitude and 77.5 degrees east latitude on Mars, and is an ancient delta topography in which sediments carried by a river that flowed into a lake about 3.9 billion ago years accumulated in the form of a fan. Persivirance investigates rocks and soil here.
Persivirance is also the first in the history of mankind’s exploration of Mars to collect soil from Mars and bring it back to Earth. If Percivirence places Martian soil samples in storage containers for collection, another rover plans to reach Mars and bring them back in the future. NASA plans to bring the Martian soil collected by Percivirence to Earth in 2031.
“The Percivirence landing is the first step in bringing Martian rock and earth to Earth,” said Thomas Jubuchen, head of NASA’s Science Mission. “We don’t know what a clean sample from Mars will tell us, but life was once beyond Earth. It will surely be monumental in content, including the fact that it may have existed.”
Retired NASA astronaut Ron Garran told CNN: “If you find traces of life on Mars, it is a surprise in itself. If you know why there are no traces similar to water, it will help to study the Earth’s climate.” . He said.
NASA is also trying to fly a drone in the atmosphere of Mars using a small drone weighing 1.8 kg, ‘Ingenuity’. The device is designed for flight experiments on Mars, where the atmosphere is thin.
Meanwhile, the Chinese Mars probe ‘Tianwon 1’, which entered the orbit of Mars on the 10th of this month, also orbits Mars from May to June, stabilizing it, and then attempts to land on the surface of Mars following Percibia. The planned landing site is Utopia Plain. When the Tianyuan 1 rover lands on the surface of Mars, China becomes the second country in the world to land on Mars after the United States.
