WATCH: NASA launches Mars Perseverance rover to the Red Planet

|

Cape Canaveral, July 30: NASA's Mars 2020 Perseverance rover lifted off successfully on Thursday at 7:50 a.m. EDT (1150 GMT) aboard a United Launch Alliance Atlas V rocket from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida.

The objective of the Mars Perseverance Rover is to seek signs of ancient life and collect rock and soil samples for a possible return to Earth.

The Mars Perseverance Rover will take about seven months to travel to the Red Planet is expected to land on Mars on February 18, 2021, after covering a distance of 300 million miles (482.8 million kms approximately). The landing site of the rover will be the Jezero Crater on the Red Planet.

China and the United Arab Emirates got a head start last week, but all three missions should reach the red planet in February after a journey of seven months and 300 million miles (480 million kilometers).

    The plutonium-powered, six-wheeled rover will drill down and collect tiny geological specimens that will be brought home in about 2031 in a sort of interplanetary relay race involving multiple spacecraft and countries. The overall cost: more than USD 8 billion.

    In addition to addressing the life-on-Mars question, the mission will yield lessons that could pave the way for the arrival of astronauts as early as the 2030s.

    "There's a reason we call the robot Perseverance. Because going to Mars is hard," NASA Administrator Jim Bridenstine said just before liftoff. "It is always hard. It's never been easy. In this case, it's harder than ever before because we're doing it in the midst of a pandemic."

    The US, the only country to safely put a spacecraft on Mars, is seeking its ninth successful landing on the planet, which has proved to be the Bermuda Triangle of space exploration, with more than half of the world's missions there burning up, crashing or otherwise ending in failure. China is sending both a rover an orbiter.

    The UAE, a newcomer to outer space, has an orbiter en route.

    It's the biggest stampede to Mars in spacefaring history. The opportunity to fly between Earth and Mars comes around only once every 26 months when the planets are on the same side of the sun and about as close as they can get.

    Launch controllers wore masks and sat spaced apart at the Cape Canaveral control centre because of the coronavirus outbreak, which kept hundreds of scientists and other team members away from Perseverance's liftoff.

    "There's nowhere else I'd rather be," said Alex Mather, the 13-year-old Virginia schoolboy who proposed the name Perseverance in a NASA competition and travelled to Cape Canaveral for the launch.

    If all goes well, the rover will descend to the Martian surface on Feb 18, 2021, in what NASA calls seven minutes of terror, in which the craft goes from 12,000 mph (19,300 kph) to a complete stop, with no human intervention whatsoever. It is carrying 25 cameras and a pair of microphones that will enable Earthlings to vicariously tag along.

    Perseverance will aim for treacherous unexplored territory: Jezero Crater, a dusty expanse riddled with boulders, cliffs, dunes and possibly rocks bearing signs of microbes from what was once a lake more than 3 billion years ago. The rover will store half-ounce (15-gram) rock samples in dozens of super-sterilized titanium tubes.

    It also will release a mini-helicopter that will attempt the first powered flight on another planet, and test out other technology to prepare the way for future astronauts, including equipment for extracting oxygen from Mars' thin carbon-dioxide atmosphere.

    The plan is for NASA and the European Space Agency to launch a dune buggy in 2026 to fetch the rock samples, along with a rocket ship that will put the specimens into orbit around Mars. Then another spacecraft will capture the orbiting samples and bring them home.
