NASA’s Perseverance rover will land on the bottom of a crater on Mars on Feb. 18.
NASA’s “Trail” Mars rover will land at the bottom of a crater on Mars on Feb. 18. It is reported that the “Trail” in the process of landing on Mars will experience “7 minutes of terror”, subjected to up to 1300 degrees Celsius.
At 7:50 a.m. on July 30, 2020, the Mars rover Perseverance (also known as the rover) will launch from Cape Canaveral, Florida, on NASA’s Mars 2020 mission. The $2.7 billion Perseverance rover will be launched from Cape Canaveral, Fla. For the first Time, the $2.7 billion Perseverance will carry a small aircraft, sophisticated instruments for searching for signs of Life, and will drill for core samples from Mars and eventually return to Earth.
The six-wheeled rover will take about seven minutes to descend from the top of the Martian atmosphere to the surface of the Red Planet, and more than 11 minutes to transmit by radio to Earth. “The seven minutes that the Trail rover faces for its final self-guided landing are what NASA Jet Propulsion Laboratory (JPL) engineers call “seven minutes of terror.
JPL descent and landing team leader Al Chen called this time the most critical and dangerous part of the Trail Rover mission.
Before landing safely, the heat shield carrying the Trail Rover will shoot through the Martian atmosphere at 12,000 mph. Seventy-five seconds after entering the Martian atmosphere, the heat shield will be subjected to a peak temperature of 1,300 degrees Celsius. Approximately four minutes later, the heat shield reaches an altitude of 7 miles above the Martian surface, the parachute opens, and the front shell of the heat shield is discarded.
When it reaches 1.3 miles above the Martian surface, the rear shell and parachute are also discarded and the landing engine, consisting of eight reducers, ignites, slowing the rover from 190 mph to just 1.7 mph.
“There’s never a guarantee of success,” Al Chen said in a recent news release. “That’s especially true when we’re trying to land the largest, heaviest, most complex rover we’ve ever built into the most dangerous locations.”
The Trail Rover will land at the bottom of a 250-meter-deep crater on Mars called Jezero, similar to the Curiosity rover’s August 2012 landing, which will be fully documented on NASA video.
When the Curiosity rover descended to the surface of Mars, NASA also said the landing time was seven minutes of terror. Because the landing time was less than the time it took for the signal to be sent from Mars to Earth, the landing process was completely autonomous for the rover, including atmospheric entry, parachute release, and an unprecedented rocket-powered hover, and the rover had to complete the entire landing procedure on its own.
The Trail will try the same “sky crane” (skycrane landing) way landing with Curiosity. The ropes will lower Trailhead to 25 feet below the Martian surface, and after Trailhead touches the surface, the ropes will detach and the skycrane will fly away.
The Trailblazer will have to do it on its own,” Al Chen said. There’s nothing we can do in the meantime.”
At the end of a journey that lasted seven months and covered more than 300 million miles (480 million kilometers), if all goes as planned, the NASA team will receive a follow-up radio signal by Feb. 18 at 3:55 p.m. EST) to confirm Trailblazer’s final landing on the ancient soil of Mars.
As the rover lands on the Red Planet, people will discover more Martian secrets, learn about the Martian landscape and formation, discover the truth about water on Mars and search for traces of life.
NASA has successfully landed on Mars eight times. Perseverance is NASA’s most advanced and intelligent Mars rover to date. It is equipped with the latest landing technology and the most cameras and microphones to capture images and sounds of Mars.
