NASA impeccably launches Perseverance, its most ambitious Mars rover yet



He Perseverance rover i Wit helicopter head to Mars, beginning their search to find ancient signs of life, fly the skies of the red planet and Blaze a journey for humans for a day follow the same.

“It’s a really important mission with the best opportunity of my life to discover evidence for life elsewhere in the solar system,” David Flannery, a member of the perseverance science team and planner at CNET, told long-term mission.

7;s next-generation robotic explorers part of the Earth in the early morning sun off the coast of Florida aboard a United Launch Alliance Atlas V. Just 20 minutes before Thursday’s launch, a magnitude 4.5 earthquake shook the propulsion laboratory of the NASA across the continent in Pasadena, California, but did not blur the illusion of the launch. Even a global pandemic he couldn’t stop it.

At 7:50 am local time / 4:50 am PT, the main engine and four rocket propellers fired on the Atlas rocket, a vehicle taller than the Leaning Tower of Pisa. The rocket lifted the Cape Canaveral launch pad with a dazzling stream of fire, steam and smoke.

The separation of the Mars 2020 spacecraft from the rocket reinforcement occurred shortly after an hour after launch. NASA’s two interplanetary automata are now traveling and will travel nearly 350 million miles on a nearly seven-month journey to the red planet.

The journey to the launch was much longer.

Eight years ago, NASA announced that he would build a Mars rover modeled closely Curiosity, which headed to the red planet in 2011. Fighting government budget cuts, NASA basically placed the rover, sometimes with remnants of its predecessor, and Perseverance was born. For scientists like Flannery, Perseverance was not just a name. Prior to the launch, he said he was nervous and optimistic, as the detachment of NASA’s scientific team had been going on for some time.

“Most of us have been working for a good decade,” he said.

Perseverance is one All in one, mobile science lab. Like its predecessor, it is approximately the size of a car, but contains a large turret at the end of a robotic arm and thicker, more robust wheels. The nuclear motor vehicle contains seven scientific instruments, two microphones and 23 cameras: nine for engineering, seven for conducting experiments and seven for watching the rover descend to the surface. It will be able to produce Stunning images like the ones that piqued curiosity, but it is also an incredibly capable alien research device, based on NASA’s previous and current exploration of the red planet.

“Pre-Mars missions have examined geology and revealed a history in which the red planet had oceans and rivers billions of years ago,” said Alan Duffy, an astronomer at Swinburne University and a leading scientist at the Royal Institution of Australia.

“Perseverance will look for the chemical signs of life within this geology, allowing us to better say how habitable a world was.”

It will be a long time before surface data begins to seep into the Earth, but there are a number of elements to mark the list of Perseverance goals.

The next goal is, of course, to land on Mars and overcome the so-called “seven minutes of terror”: 420 seconds between hitting Mars’ atmosphere and touching its surface.

“Landing is the real part,” Flannery said. “We have some heritage with this particular mission: the landing system has worked with Curiosity. I’m optimistic.”

The maneuver is scheduled to take place in February 2021. If all goes as planned, Perseverance will finally roll its feet on the dusty ground of Mars and begin its scientific mission. The scientific payload aboard Perseverance includes an X-ray fluorescence instrument, spectroscopy instruments, and various radars. Together, they will allow Perseverance to observe the chemistry of its landing site, Crater Lake.

“Jezero Crater was once an ancient lake full of water about 3.5 billion years ago and the conditions are ideal for searching for possible traces of ancient life,” said Brendan Burns, an astrobiologist at the University of New Wales of the South, Australia. The mission plans to snatch land and sediment from Jezero and plans to cache these samples and leave them on the surface of Mars for future missions.

“The rover is collecting rocks on Mars that will eventually be taken back to Earth for analysis,” said Bonnie Teece, PhD in astrobiology. studying at the University of New South Wales. “These precious few grams of Martian rock can totally change our understanding of our nearest neighbor.”

For students like Teece, perseverance offers many opportunities. Duffy points out that the rover could continue to produce data for years to come.

“Generations of scientists depend on this mission being successfully launched from our planet and landing on another,” he said.

The interplanetary highway between Earth and Mars is as busy as ever. For the past two weeks, the The United Arab Emirates and China have sent missions to the red planet. The UAE launched an atmospheric probe known as Hope, which aims to examine Mars from orbit and provide a holistic view of the planet’s atmospheric cycles, potentially answering long-running questions about its unusual composition of gases. China, on the other hand, is attempting a mission to land on the surface of Mars. Her Tianwen-1 Mission it consists of three spaceships: an orbiter, a terrifier and a rover that currently has no name.

Perseverance and naivete keep them, but they are not far behind.

“This is a monumental occasion,” Burns said. “The candle has been lit.”
