CAPE CANAVERAL, Fla. — 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.
Watch the NASA team’s remarks in the player above.
The world got its first close-up look at a Mars landing on Friday, as NASA released a stunning picture of its newest rover being lowered onto the dusty red surface.
The photo was released less than 24 hours after the Perseverance rover successfully touched down near an ancient river delta, where it will search for signs of ancient life and set aside the most promising rock samples for return to Earth in a decade.
NASA equipped the spacecraft with a record 25 cameras and two microphones, many of which were turned on during Thursday’s descent.
The rover is shown in stunning detail just 6 1/2 feet (2 meters) off the ground, being lowered by cables attached to an overhead sky crane, the red dust kicked up by rocket engines. NASA promises more photos in the next few days and possibly also an audio recording of the descent.
“This is something that we’ve never seen before,” flight system engineer Aaron Stehura noted at a news conference. “It was stunning, and the team was awestruck. There’s just a feeling of victory that we were able to capture these and share it with the world.”
Chief engineer Adam Steltzner called the picture “iconic,” putting it right up there with photos of Apollo 11’s Buzz Aldrin on the moon, Saturn as seen by Voyager 1, and the Hubble Space Telescope’s “pillars of creation” shot.
A number of thumbnail images have been beamed down so far, too many to count, said Pauline Hwang, strategic mission manager for surface operations. “The team went wild” at seeing these first pictures, she said.
“We were just kind of like on cloud nine .. this weird dreamlike state, we can’t actually believe this is what we’re seeing,” she said.
The spacecraft is healthy, according to officials, after landing on a flat, safe surface in Jezero Crater with just 1 degree of tilt and relatively small rocks nearby. For now, the systems still are being checked. It will be at least a week before the rover starts driving.
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.
“Now the amazing science starts,” a jubilant Thomas Zurbuchen, NASA’s science mission chief, said at a news conference, where he theatrically ripped up the contingency plan in the event of a failure and threw the document over his shoulders.
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 rocks. 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 containing possible signs of bygone microscopic life. Three to four dozen chalk-size samples will be sealed in tubes and set aside to be retrieved eventually by another 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 will also seek 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 maneuver 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 meters) to the surface.
It took a nail-biting 11 1/2 minutes for the signal confirming the landing to reach Earth, setting off back-slapping and fist-bumping among flight controllers wearing masks against the coronavirus.
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.
“Take that, Jezero!” a controller called out.
NASA said that the descent was flawless and that the rover came down in a “parking lot” — a relatively flat spot amid hazardous rocks. Hours after the landing, Matt Wallace, NASA deputy project manager, reported that the spacecraft was in great shape.
Mars has proved a treacherous place for the world’s spacefaring nations, the U.S. included. 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 the surface after its engines cut out prematurely.
President Joe Biden tweeted congratulations over the landing, saying: “Today proved once again that with the power of science and American ingenuity, nothing is beyond the realm of possibility.”
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,” said David Parker, the European agency’s director of human and robotic exploration.
Former astronaut and one-time NASA science chief John Grunsfeld tweeted that Perseverance’s landing was “exactly the good news and inspiration we need right now.”
“Reminds us all that we will persevere COVID and political turmoil and that the best is yet to come,” he said.
