NASA is flawlessly launching persistence, its largest rover to date



The Persistence rover and Ingenuity the helicopter goes to Mars, starting its search to find ancient signs of life, fly in the red sky and ignite a journey for people to one day imitate him.

“This is a really significant mission with the best chance in my life to find evidence of life elsewhere in the solar system,” said David Flannery, a member of the persistence research team and long-term mission planner.

The next generation of NASA researchers the Earth has departed In the early sun off the coast of Florida aboard the Atlas V. United Launch Alliance Atlas V. Just 20 minutes before Thursday̵

7;s launch, a 4.5-degree earthquake destroyed NASA’s jet lab across the continent in Pasadena, California, but it did not dampen the excitement of the launch. Even a global pandemic could not stop it.

At 7:50 a.m. local time / 4:50 a.m. PT, the main engine and four rocket boosters fired at the Atlas rocket, a vehicle taller than the Leaning Tower of Pisa. The rocket rose from the Cape Canaveral launch pad with a dizzying stream of fire, steam and smoke.

The Mars 2020 spacecraft was separated from the rocket booster only an hour after launch. Two NASA interplanetary spacecraft are now on the road and will travel nearly 350 million miles in almost seven months to the Red Planet.

The path to launch was much longer.

Eight years ago, NASA announced that will build a rover “Mars” simulated closely Interest, who went to the Red Planet in 2011. Sucked into government budget cuts, NASA essentially tied the rover, sometimes using the remnants of part of its predecessor, and Persistence was born. For scientists like Flannery, persistence was not just a name. Before starting work, he said that he was nervous and optimistic because he had worked for a long time on the NASA research team.

“Most of us have been working on this for most of the decade,” he said.

Persistence is this comprehensive, rolling scientific laboratory. Like its predecessor, it is about the size of the car, but contains a large tower at the end of the robotic arm and thicker, stronger wheels. The nuclear vehicle contains seven scientific instruments, two microphones and 23 cameras – nine for technology, seven for experiments and seven for watching the rover descend to the surface. It will be able to produce stunning images similar to those flashed by Curiosity, but it is also an incredibly capable device for searching for aliens, based on previous and current NASA explorations on the Red Planet.

“Previous missions to Mars have studied geology and discovered the history of the red planet’s 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.

“Persistence will look for chemical signs of life within this geology, allowing us to better say how alive this world was.”

However, it will be a long time before the data from the surface begins to filter back to Earth, but there are many items to note the list of objective tasks of “Constancy”.

The next milestone is, of course, landing on Mars and overcoming the so-called “seven-minute terror” – 420 seconds between the impact of the Martian atmosphere and touching its surface.

“Landing is a really hard part,” Flannery said. “We have a legacy with this mission – the landing system worked with Curiosity. I’m an optimist.”

The maneuver is scheduled for February 2021. If all goes according to plan, perseverance will finally spill over to the watchful land of Mars and begin a scientific mission. The payload on the Perseverance includes an X-ray fluorescent instrument, spectroscopic instruments and a number of radars. Together, they will allow persistence to observe the chemistry of his landing, Crater Lake.

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

“The rover is collecting rocks on Mars, which will eventually be returned to Earth for analysis,” said Bonnie Tees, a doctor of astrobiology. student at the University of New South Wales. “These precious few grams of Martian rock can completely change our understanding of our nearest neighbor.”

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

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

The interplanetary highway between Earth and Mars is as busy as ever. In the last two weeks The United Arab Emirates and China have sent missions to the Red Planet. The UAE has launched an atmospheric probe known as Hope, which aims to survey Mars from orbit and provide a holistic view of the planet’s atmospheric cycles, potentially answering long-standing questions about its unusual gas composition. China, on the contrary, is mission attempt to land on the surface of Mars. Him Mission Tianwen-1 consists of three spaceships: an orbital, a landing party and a currently unnamed rover.

Perseverance and ingenuity lag behind, but not far behind.

“It’s a monumental occasion,” Burns said. “The candle was lit.”
