This illustration provided by NASA shows the Perseverance rover, bottom, landing on Mars. Hundreds of critical events must execute perfectly and exactly on time for the rover to land safely on Feb. 18, 2021. Entry, Descent, and Landing, or "EDL," begins when the spacecraft reaches the top of the Martian atmosphere, traveling nearly 12,500 mph (20,000 kph). EDL ends about seven minutes after atmospheric entry, with Perseverance stationary on the Martian surface. (NASA/JPL-Caltech via AP)

‘Touchdown confirmed!’: NASA rover lands on Mars to look for signs of ancient life

Perseverance becomes the ninth spacecraft since the 1970s to successfully land on the red planet

A NASA rover streaked through the orange Martian sky and landed on the planet Thursday, accomplishing the riskiest step yet in an epic quest to bring back rocks that could answer whether life ever existed on Mars.

Ground controllers at the space agency’s Jet Propulsion Laboratory in Pasadena, California, leaped to their feet, thrust their arms in the air and cheered in both triumph and relief on receiving confirmation that the six-wheeled Perseverance had touched down on the red planet, long a deathtrap for incoming spacecraft.

It took a tension-filled 11 1/2 minutes for the signal to reach Earth.

“Touchdown confirmed! Perseverance safely on the surface of Mars, ready to begin seeking signs of past life,” flight controller Swati Mohan announced to back-slapping, fist-bumping colleagues wearing masks against the coronavirus.

The landing marks the third visit to Mars in just over a week. Two spacecraft from the United Arab Emirates and China swung into orbit around Mars on successive days last week. All three missions lifted off in July to take advantage of the close alignment of Earth and Mars, journeying some 300 million miles in nearly seven months.

Perseverance, the biggest, most advanced rover ever sent by NASA, became the ninth spacecraft since the 1970s to successfully land on Mars, every one of them from the U.S.

The car-size, plutonium-powered vehicle arrived at Jezero Crater, hitting NASA’s smallest and trickiest target yet: a 5-by-4-mile strip on an ancient river delta full of pits, cliffs and fields of rock. Scientists believe that if life ever flourished on Mars, it would have happened 3 billion to 4 billion years ago, when water still flowed on the planet.

Over the next two years, Percy, as it is nicknamed, will use its 7-foot (2-meter) arm to drill down and collect rock samples with possible signs of bygone microscopic life. Three to four dozen chalk-size samples will be sealed in tubes and set aside on Mars to be retrieved by a fetch rover and brought homeward by another rocket ship. The goal is to get them back to Earth as early as 2031.

Scientists hope to answer one of the central questions of theology, philosophy and space exploration.

“Are we alone in this sort of vast cosmic desert, just flying through space, or is life much more common? Does it just emerge whenever and wherever the conditions are ripe?” said deputy project scientist Ken Williford. “We’re really on the verge of being able to potentially answer these enormous questions.”

China’s spacecraft includes a smaller rover that also will be seeking evidence of life — if it makes it safely down from orbit in May or June.

Two older NASA landers are still humming along on Mars: 2012’s Curiosity rover and 2018’s InSight.

Perseverance was on its own during its descent, a manoeuvr often described by NASA as “seven minutes of terror.”

Flight controllers waited helplessly as the preprogrammed spacecraft hit the thin Martian atmosphere at 12,100 mph (19,500 kph), or 16 times the speed of sound, slowing as it plummeted. It released its 70-foot (21-meter) parachute and then used a rocket-steered platform known as a sky crane to lower the rover the final 60 or so feet (18 metres) to the surface.

Perseverance promptly sent back two grainy, black-and-white photos of Mars’ pockmarked, pimply-looking surface, the rover’s shadow visible in the frame of one picture. The rover appeared to have touched down about 35 yards from the nearest rocks.

“Take that, Jezero!” a controller called out.

Mars has proved a treacherous place. In the span of less than three months in 1999, a U.S. spacecraft was destroyed upon entering orbit because engineers had mixed up metric and English units, and an American lander crashed on Mars after its engines cut out prematurely.

In addition to mining the rocks, Perseverance will conduct an experiment in which it will convert small amounts of the mostly carbon dioxide atmosphere into oxygen, a process that could be a boon to future astronauts by providing breathable air and an ingredient for rocket fuel.

The rover is also equipped with a record 25 cameras and two microphones, many of them turned on during descent. Among the never-before-seen views NASA intends to send back in the next couple days: the enormous supersonic parachute billowing open and the ground getting closer.

“A feast for the eyes and ears. It’s really going to be spectacular,” observed Arizona State University’s Jim Bell, lead scientist for a pair of mast cameras that will serve as the rover’s eyes.

NASA is teaming up with the European Space Agency to bring the rocks home. Perseverance’s mission alone costs nearly $3 billion.

The only way to confirm — or rule out — signs of past life is to analyze the samples in the world’s best labs. Instruments small enough to be sent to Mars wouldn’t have the necessary precision.

“It’s really the most extraordinary, mind-boggingly complicated and will-be history-making exploration campaign,” David Parker, the European Space Agency’s director of human and robotic exploration, said on the eve of landing.
