NASA launches Mars rover to look for signs of ancient life

Cape Canaveral (US), July 30

The largest, most subtle Mars rover ever constructed — a car-size automobile bristling with cameras, microphones, drills and lasers — blasted off for the purple planet Thursday as a part of an bold, long-range undertaking to convey the primary Martian rock samples again to Earth to be analysed for proof of historical life.

NASA’s Perseverance rode a mighty Atlas V rocket into a transparent morning sky on the planet’s third and ultimate Mars launch of the summer season. China and the United Arab Emirates acquired a head begin final week, however all three missions ought to attain their vacation spot in February after a journey of seven months and 480 million km.

The plutonium-powered, six-wheeled rover will drill down and acquire tiny geological specimens that can be introduced residence in about 2031 in a form of interplanetary relay race involving a number of spacecraft and nations. The general value: greater than USD eight billion.

NASA’s science mission chief, Thomas Zurbuchen, pronounced the launch the beginning of “humanity’s first spherical journey to a different planet.”

“Oh, I liked it, punching a gap within the sky, proper? Getting off the cosmic shore of our Earth, wading on the market within the cosmic ocean,” he mentioned. “Each time, it will get me.”

Along with addressing the life-on-Mars query, the mission will yield classes that might pave the best way for the arrival of astronauts as early because the 2030s.

“There’s a cause we name the robotic Perseverance. As a result of going to Mars is tough,” NASA Administrator Jim Bridenstine mentioned simply earlier than liftoff. “It’s all the time arduous. It’s by no means been simple. On this case, it’s tougher than ever earlier than as a result of we’re doing it within the midst of a pandemic.” 

The US, the one nation to securely put a spacecraft on Mars, is looking for its ninth profitable touchdown on the planet, which has proved to be the Bermuda Triangle of area exploration, with greater than half of the world’s missions there burning up, crashing or in any other case ending in failure.

China is sending each a rover an orbiter.

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

It’s the most important stampede to Mars in spacefaring historical past. The chance to fly between Earth and Mars comes round solely as soon as each 26 months when the planets are on the identical facet of the solar and about as shut as they’ll get.

Launch controllers wore masks and sat spaced aside on the Cape Canaveral management heart due to the coronavirus outbreak, which saved lots of of scientists and different group members away from Perseverance’s liftoff.

“That was overwhelming. Total, simply ‘Wow!’” mentioned Alex Mather, the 13-year-old Virginia schoolboy who proposed the title Perseverance in a NASA competitors and watched the launch in individual along with his mother and father.

The launch went off on time at 7:50 a.m. regardless of a 4.2-magnitude earthquake 20 minutes earlier than liftoff that shook Southern California, the location of NASA’s Jet Propulsion Laboratory, which is overseeing the rover mission.

If all goes effectively, the rover will descend to the Martian floor on February 18, 2021, in what NASA calls seven minutes of terror, through which the craft goes from 19,300 kmph to an entire cease, with no human intervention in anyway. It’s carrying 25 cameras and a pair of microphones that can allow Earthlings to vicariously tag alongside.

Perseverance will intention for treacherous unexplored territory: Jezero Crater, riddled with boulders, cliffs, dunes and presumably rocks bearing indicators of microbes from what was as soon as a lake greater than three billion years in the past. The rover will retailer half-ounce (15-gram) rock samples in dozens of super-sterilized titanium tubes.

It additionally will launch a mini helicopter that can try the primary powered flight on one other planet, and take a look at out different know-how to arrange the best way for future astronauts. That features tools for extracting oxygen from Mars’ skinny carbon-dioxide environment.

The plan is for NASA and the European Area Company to launch a dune buggy in 2026 to fetch the rock samples, together with a rocket ship that can put the specimens into orbit round Mars. Then one other spacecraft will seize the orbiting samples and produce them residence.

Samples taken straight from Mars, not drawn from meteorites found on Earth, have lengthy been thought of “the Holy Grail of Mars science,” based on NASA’s authentic and now-retired Mars czar, Scott Hubbard.

To definitively reply the profound query of whether or not life exists — or ever existed — past Earth, the samples have to be analyzed by the most effective electron microscopes and different devices, far too huge to suit on a spacecraft, he mentioned.

“I’ve wished to know if there was life elsewhere within the universe since I used to be 9 years outdated. That was greater than 60 years in the past,” the 71-year-old Hubbard mentioned from his Northern California cabin.

“However simply possibly, I’ll reside to see the fingerprints of life come again from Mars in a kind of rock samples.” Stated Bridenstine: “There may be nothing higher than bringing samples again to Earth the place we are able to put them in a lab and we are able to apply each factor of know-how in opposition to these samples to make determinations as as to whether or not there was, at one time, life on the floor of Mars.”

Two different NASA landers are additionally working on Mars: 2018’s InSight and 2012’s Curiosity rover. Six different spacecraft are exploring the planet from orbit: three from the US, two from Europe and one from India. AP
