NASA’s Perseverance rover has successfully landed on the surface of Mars after surviving a blazing seven-minute plunge into the Martian atmosphere The rover’s clean landing sets the stage for a multi-year journey to travel the Jezero crater of the red planet in search of ancient signs of life

“Touchdown confirmed,” said Swati Mohan, member of NASA’s Entry, Descent, and Landing team “Perseverance is safe on the surface of Mars, ready to start looking for signs of past life” The landing team of about 30 engineers from NASA’s Jet Propulsion Laboratory in California jumped from their sits and clapped at confirmation Moments after landing, Perseverance returned its first image from one of its 19 cameras

Perseverance hit Mars’ atmosphere on time at 3:48 p.m. ET at a speed of about 12,100 miles per hour, plunging toward the surface in an infamously difficult streak that engineers call the “seven minutes. of terror “With an 11-minute communication delay between Mars and Earth, the spacecraft had to complete its seven-minute dive on its own with an incredibly complex set of pre-programmed instructions

Enduring searing heat, the rover was protected by a protective shell and a parachute to help slow it down A descent stage with six rocket thrusters fired as it neared the surface, slowing Perseverance to a much calmer level of 2 mph While hugging the rover, the descent stage hovered 66 feet above from the surface to execute a skycrane maneuver, where he gently lowered Perseverance over a set of cables the rest of the way to the surface

With its six wheels planted on the surface, the rover cut the cables to the skycrane, prompting the rocket-powered descent stage to pull away from Perseverance

The on-time landing at 3:55 p.m. ET marks NASA’s sixth successful landing on the Red Planet The $ 2.7 billion rover is essentially a 2,263-pound laboratory on wheels: over the next few years, Perseverance will pass through Jezero de Mars crater to collect soil samples for a future recovery mission, analyze the composition of Martian rocks with a laser beam camera system, and deploy a helicopter named Ingenuity, a four-foot-wide rotorcraft that will demonstration of the first powered flight on another planet

Spirits were on top at a post-landing press conference Thomas Zurbuchen, NASA’s top scientist, was elated and began his remarks on the Perseverance landing victory by posting a print of the mission contingency plan – a plan for the team in case the mission goes wrong – and tearing it in half “Here’s the contingency plan!” he said before tearing up the paper and throwing it behind him, eliciting applause in the JPL auditorium

“Now the fun really begins,” said Lori Glaze, director of NASA’s Planetary Science Division The science team is already analyzing the several low-resolution images the rover has already sent back to Earth, has t she declared Additional footage will be released throughout the week, with the first audio drop starting Thursday night and the first high-definition video of Perseverance’s landing slated for Monday

The SUV-sized rover has traveled 293 million kilometers since its launch last summer on top of a United Launch Alliance Atlas V rocket.It has been launched for a slim window of time as the Earth and Mars were closely aligned in their orbits around the Sun This alignment only takes place once every two years, and NASA launched its rover around the same time as China and the United Arab Emirates, whose Martian spacecraft also reached the planet earlier this this month China’s Tianwen-1 probe, which arrived in Mars orbit on February 10, will deploy a lander and rover in the coming months, reaching Perseverance just over a thousand kilometers from the surface of Mars

Perseverance’s journey into space went even more uneventfully than expected Towards the end of its seven-month journey, the Perseverance cruise stage performed fewer orbital correction maneuvers than originally planned, in part thanks to an ultra-precise insertion on its Martian trajectory during its launch “When we hit the target, that means they had a ton more thruster” that NASA didn’t have to use on its trip to Mars, ULA CEO Tory Bruno told The Verge Unlike Tianwen-1, which hangs in orbit before heading for the surface, Perseverance reserved it directly for the surface by reaching Mars.

Jezero crater posed the most difficult landing site NASA has faced Perseverance had to avoid the crater’s sheer cliffs, massive boulders, and dangerously sandy pits to reach its landing point Scientists believe the 28-mile-wide hole was a river delta some 3 billion years ago – potentially a gold mine for fossilized microorganisms Its mix of different rock formations offers researchers a plethora of samples potential to be collected during his mission

Zurbuchen said engineers at Perseverance are already moving forward with the next step in NASA’s ambitions to Mars: the Sample Return Mission, a joint effort with the European Space Agency to send a fleet spaceships on Mars and collect soil samples Perseverance will disperse Jezero crater This mission is expected to launch in 2026

“Many concrete steps are also underway to reach another horizon goal, which is also human exploration of Mars,” said Zurbuchen, remotely planning to send astronauts to the Red Planet in the 2030s
