NASA’s Perseverance rover has successfully landed on the surface of Mars after surviving a seven-minute jump through the Martian atmosphere.The clean landing of the rover sets the stage for a year-long journey to the Jezero crater of the red planet following ancient signs of life to search

“Touchdown confirmed,” said Swati Mohan, member of NASA’s entry, descent, and landing team. “Perseverance is safe on the surface of Mars, ready to search for the signs of past life, the landing team of around 30 engineers on the jet NASA’s Propulsion Laboratory in California jumped from their seats and cheered the confirmation. Shortly after touching it down, Perseverance beamed his first image back from one of its 19 cameras

Persistence hit the Martian atmosphere punctually at 3pm48 o’clock ET at a speed of about 12100 miles per hour and surfaced in an extremely challenging sequence that engineers call “seven minutes of terror.” With an 11-minute communication delay between Mars and Earth, the spaceship had to perform its seven-minute jump itself with an incredibly complex set of preprogrammed instructions. p>

The rover withstood the heat and was shielded by a protective cover and parachute to help slow down a six rocket-engine descent stage fired as it neared the surface, slowing endurance to a much quieter 2 mph Descent step, clutching the rover, hovered 66 feet above the surface to perform a “Skycrane” maneuver that gently lowered stamina on a set of cables the rest of the way to the surface

With its six wheels planted on the surface, the rover snapped the Skycrane cables, causing the rocket-propelled descent stage to move a long way from persistence

The punctual landing at 1555 p.m. ET marks NASA’s sixth successful landing on the Red Planet The $ 27 billion rover is essentially a 2ndA 263-pound laboratory on wheels: Over the next few years, Perseverance will traverse the Jezero crater on Mars to collect soil samples for a future recovery mission and to analyze the composition of Martian rocks with a laser-beam camera system and deploy a helicopter called Ingenuity, a four-foot-wide rotary-wing aircraft that will demonstrate the first powered flight on another planet

The mood was high during a post-landing press conference Thomas Zurbuchen, NASA’s senior science officer, was delighted and began his talk on Perseverance’s landing victory by holding up a printout of the mission’s contingency plan – a blueprint for the team for the In case the mission goes wrong – and tore it in half “Here’s the contingency plan!” he said before tearing the paper apart and throwing it behind him, which caused applause in the JPL auditorium

“Now the fun really starts,” said Lori Glaze, director of NASA’s Planetary Science Division, with the science team already analyzing the various low-resolution images that the rover has already beamed back to Earth, she said later this week more pictures will be received The first drop of audio is expected on Thursday evening and the first high-resolution video of the landing of Perseverance on Monday

The SUV-sized rover has traveled 293 million miles on a United Launch Alliance Atlas V rocket since launch last summer.It took off during a narrow window of time when Earth and Mars were closely aligned in their orbits around the sun That alignment only happens 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 month, China’s Tianwen-1 probe, which launched on Dec. Arrived into Mars orbit in February, a lander and rover will deploy in the coming months, joining Perseverance on the Martian surface a little over a thousand miles away

Perseverance’s voyage through space was even more uneventful than expected Towards the end of its seven-month voyage, the Perseverance cruise stage performed fewer orbit correction maneuvers than originally planned, in part due to an ultra-precise insertion into Mars’ trajectory at launch “When we hit the bull’s eye it means they had a ton more propellant” that NASA didn’t have to use on their trip to Mars, ULA CEO Tory Bruno told The Verge Unlike Tianwen-1, that is in orbit before it goes to the surface, Perseverance booked it directly to the surface when it reached Mars

Jezero Crater was the toughest landing site NASA faced Perseverance had to stay away from the crater’s steep cliffs, massive boulders, and dangerously sandy pits to reach its landing site, scientists believe the 28 mile wide hole was a river delta about 3.5 billion years ago – possibly a gold mine for petrified microorganisms The mix of different rock formations offers researchers a wide variety of potential samples to collect during their mission

Zurbuchen said that Perseverance engineers are already driving the next stage in NASA’s Mars ambitions: the sample return mission, a collaborative effort with the European Space Agency to send a fleet of spacecraft to Mars and collect soil samples from the Jezero Crater This mission is slated to start sometime in 2026

“Many concrete steps are also being taken towards another horizon goal, namely human exploration of Mars,” said Zurbuchen, floating in the distance plans to send astronauts to the Red Planet sometime in the 2030s
