NASA launched flawlessly, its most ambitious Mars rover yet


Firmness Rover and Simplicity Choppers are routes to Mars, beginning their quest to find ancient signs of life, flying the skies of the red planet and Follow the journey for a day for humans.

“This is the best opportunity in my lifetime to search for evidence for life elsewhere in the solar system,” said David Flannery, a member of the Perspons Science team and a long-term planner for the mission.

NASA’s next generation robot explorer Left the earth Florida Coast’s morning sun in the United Launch Alliance Atlas V just 20 minutes before its launch on Thursday morning 4.5 magnitude earthquake NASA’s Jet Propulsion Laboratory rocked the continent in Pasadena, California, but it did not dampen the excitement of the launch. even though Global universal epidemic Could not stop it.

At: 50/9: 50 am local time, PT’s main engine and four rocket boosters were fired at the Atlas rocket, a vehicle longer than the Leaning Tower of Pisa. The rocket lifted the Cape Canaveral launch pad with a blazing current of fire, steam and smoke.

The Mars 2020 spacecraft was separated from the rocket booster an hour after its launch. NASA’s two interplanetary automatons are now on their journey and will travel approximately 350 million miles on a seven-month trip to the Red Planet.

The journey to launch was very long.

Eight years ago, NASA Announced that it will build a Mars rover Modeled closely Curiosity, Which left for the Red Planet in 2011. Struggling with government budget cuts, NASA essentially teamed up with Rover, sometimes using the leftovers of its predecessor, and perseverance was born. For scientists like Flannery, persistence was not just a name. Prior to the launch, he said he was nervous and optimistic because the liftoff was too long for NASA’s science team to arrive.

“Most of us have been working on it for the better part of a decade,” he said.

Firmness is one All-in-One, Rolling Science Laboratory. Like its predecessor, it is about the size of a car, but has a large turret at the end with robotic hands and thicker, stronger wheels. The nuclear-powered vehicle consists of seven science equipment, two microphones and 23 cameras – nine for engineering, seven for conducting experiments and seven for surface viewing of the Rover. It will be able to produce Stunning images like back by curiosity, But it is also an incredibly capable alien-seeking device, building on NASA’s past and present exploration on the Red Planet.

“Previous missions to Mars examined geology and revealed a history that contained billions of years ago the oceans and rivers of the red planet,” said Alan Duffy, an astronomer at Swinburne University and head scientist at the Royal Institution of Australia.

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

It will take a long time before the data from the surface will start filtering back to Earth, however, and there are a host of items to close the objective list of persistence.

The next milestone, of course, is in landing on Mars and overcoming the so-called “seven minutes of terror” – 420 seconds between hitting Mars’ atmosphere and touching down on its surface.

“Landing is the really tough part,” Flannery said. “We have some legacies with this particular mission – the landing system acted with curiosity. I’m optimistic.”

The exercise is scheduled to take place in February 2021. If all goes according to plan, the firmament will eventually roll its feet into the dusty soil of Mars and begin its science mission. The strongly-mounted science payload includes an X-ray fluorescence instrument, spectroscopy equipment, and several radars. Together, they will enable persistence to follow the chemistry of their landing site, Jagero crater.

Brendan Burns, an astronomer at the University of New South Wales, Australia, said, “The Jagero crater was an ancient lake filled with water some 3.5 billion years ago and the conditions are ideal for exploring potential traces of ancient life.” The mission planned to snatch soil and sediment from Jessero and to cache those samples and leave them on the surface of Mars for future missions.

“The rover is collecting rocks on Mars, which will eventually be brought back to Earth for analysis,” said Bonnie Tees, an astronomy Ph.D. Student at the University of New South Wales. “Those precious few villages can change our understanding of our closest neighbor.”

For students like Tees, perseverance provides plenty of opportunities. Duffy notes that the rover can continue to produce data for years to come.

“The generation of scientists depends on the mission that it is successfully launching from our planet and landing on another,” he said.

The inter-freelance between Earth and Mars is as busy as it once was. In the last two weeks, Both the United Arab Emirates and China have sent missions to the Red Planet. The UAE launched an atmospheric probe called HOPE, which aims to probe Mars’ orbit and provide a holistic view of the planet’s atmospheric cycles, likely answering long-standing questions about the unusual composition of gases. gives. In contrast, China is A mission attempt to land on the surface of Mars. its Tianwen-1 Mission Composed of three spacecraft: an orbiter, a lander and a currently unnamed rover.

Persistence and ingenuity are leaving them behind but are not far behind.

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