  • 7 Minutes to Mars: NASAs Perseverance Rover Attempts Most Dangerous Landing Yet


    All landings on Mars are difficult, but NASA's Perseverance rover is attempting to touch down in the most challenging terrain on Mars ever targeted.

    The intense entry, descent, and landing phase, known as EDL, begins when the spacecraft reaches the top of the Martian atmosphere. Engineers have referred to the time it takes to land on Mars as the seven minutes of terror.

    The landing sequence is complex and targeting a location like Jezero Crater on Mars is only possible because of new landing technologies known as Range Trigger and Terrain-Relative Navigation.

    The Perseverance rover is set to land on the surface of Mars on February 18, 2021.

  • 7 Minutes of Terror! How will the Perseverance Rover Land on Mars?


    The 7 minutes of Terror! What are the 7 minutes of Terror? How will NASA's Mars Peseverance Rover land? Is it any different from Curiosity's landing in 2012? Let's talk about that!

    0:00 Introduction
    0:50 7 Minutes of Terror
    2:10 Overview of Landing Sequence
    5:21 Aeroshell and Heat Sheild
    9:48 Supersonic Parachute
    11:45 Powered Descent Stage
    12:43 Percy vs Curiosity
    13:02 Conclusion

    In this video, we will discuss the Entry, Descent, and Landing sequence for the Mars 2020 mission. Mars 2020 consists of the Perseverance Rover and the Ingenuity Helicopter. After traveling through space for seven months, Percy will make it to Mars. As it enters the atmosphere, it will begin the seven-minute landing sequence. Called the 7 minutes of terror. The first part is Entry, as the spacecraft enters the Martian atmosphere. Using its heat shield and aeroshell, it will slow the spacecraft down. Meanwhile, thrusters and counterweights are used to make sure it remains on track.

    After three minutes, the new Range Trigger technique will help NASA decide when to deploy the supersonic parachutes. While descending, the heat shield is dropped, and downward-facing cameras help detect the best locations to land Percy. Soon after, the powered descent phase begins, where the retrorockets slow the spacecraft further. Then just above the surface, using the Mars sky crane, the rover will safely touchdown on Mars.

    Thanks for watching! And consider subscribing if you enjoyed this video!

  • How the Seven Minutes of Terror Could Make or Break NASA’s Perseverance Rover


    NASA's Perseverance rover is entering the most intense phase of its mission: landing on the red planet.

    The United Arab Emirates’ Hope orbiter and China’s Tianwen-1 mission have already arrived at Mars’ orbit. And it’s been seven months since they took off, but for Mars 2020 and Tianwen-1, one of the hardest parts is still yet to come: actually sticking the landing on the red planet. Fondly known as seven minutes of terror.

    It takes about seven minutes from the time that the spacecraft first comes in contact with Mars' atmosphere until we get down to the ground. This part of the mission is known as the Entry, Descent, and Landing or EDL. And it all starts with the spacecraft hurtling through the martian atmosphere at roughly 20,000 kilometers per hour, causing the external heat shield to heat up to around 1,300 degrees celsius.

    With some help from its heat shield, the vehicle slows down to about 1,600 kilometers per hour, and this is when its supersonic parachute deploys. The heat shield then pops off, but the parachute doesn't slow the rover down enough for a safe landing. The main reason for this is because of Mars’ thin atmosphere.

  • NASA Mars 2020 Perseverance Rover Landing! ???? Live


    Mars 2020 is a Mars rover mission by NASA's Mars Exploration Program that includes the Perseverance rover and the Ingenuity helicopter drone. It was launched on 30 July 2020 at 11:50 UTC, and plans to touch down in Jezero crater on Mars on 18 February 2021.

    Perseverance will investigate an astrobiologically relevant ancient environment on Mars and investigate its surface geological processes and history, including the assessment of its past habitability, the possibility of past life on Mars, and the potential for preservation of biosignatures within accessible geological materials. It will cache sample containers along its route for retrieval by a potential future Mars sample-return mission. The Mars 2020 mission was announced by NASA on 4 December 2012 at the fall meeting of the American Geophysical Union in San Francisco. The Perseverance rover's design is derived from the Curiosity rover, and will use many components already fabricated and tested, new scientific instruments and a core drill.

    Mars 2020 was the third of three space missions sent toward Mars during the July 2020 Mars launch window, with missions also launched by the national space agencies of the United Arab Emirates (Hope orbiter) and China (Tianwen-1, with an orbiter, lander, and rover). All three are expected to arrive at Mars in February 2021.

  • Livestream Replay - NASA/JPL - Perseverance Rover Landing - Jezero Crater/ Mars - February 18, 2021


    NASA landed their 2020 Mars Rover Perseverance on February 18 at 3:55 p.m. EST (20:55 UTC) in a thrilling and exciting landing on Mars at Jezero Crater.

    “Perseverance is NASA’s most ambitious Mars rover mission yet, focused scientifically on finding out whether there was ever any life on Mars in the past,” said Thomas Zurbuchen, associate administrator for the Science Mission Directorate at NASA Headquarters in Washington. “To answer this question, the landing team will have its hands full getting us to Jezero Crater – the most challenging Martian terrain ever targeted for a landing.”

    Jezero is a basin where scientists believe an ancient river flowed into a lake and deposited sediments in a fan shape known as a delta. Scientists think the environment here was likely to have preserved signs of any life that gained a foothold billions of years ago – but Jezero also has steep cliffs, sand dunes, and boulder fields. Landing on Mars is difficult – only about 50% of all previous Mars landing attempts have succeeded – and these geological features make it even more so. The Perseverance team is building on lessons from previous touchdowns and employing new technologies that enable the spacecraft to target its landing site more accurately and avoid hazards autonomously.

    Shortly after Perseverance landed on the surface, the first pictures of the engineering cam were transmitted. Now in the upcoming days, engineers will also check on the health of the rover and deploy the remote sensing mast (otherwise known as its “head”) so it can take more pictures. The Perseverance team will then take more than a month to thoroughly inspect the rover and load new flight software to prepare for its search for ancient life on Mars. During the same period, the Ingenuity Mars Helicopter team will be making sure their small but mighty robot is prepared for the first attempt at controlled, powered aerodynamic flight on another planet.

    Team members who worked on NASA's Perseverance mission held a news conference at JPL on Feb. 18 after the rover’s successful landing on Mars.


  • Perseverance Landing a Rover on Mars Live 2021


    The search for signs of ancient life on Mars. The first helicopter fly on another planet. The first recordings of sound on the red planet.

    NASA's most sophisticated rover to date has a packed agenda for the next few years once it lands on the surface of Mars today.

    If all goes well -- and there is a chance it will not -- Perseverance will land around 3:55 p.m. ET.

    The rover has been traveling through space since launching from Cape Canaveral, Florida, at the end of July. When it reaches Mars, Perseverance will have traveled 292.5 million miles on its journey from Earth.

    Perseverance is NASA's first mission that will search for signs of ancient life on another planet to help answer the big question: Was life ever present on Mars? The rover will explore Jezero Crater, the site of an ancient lake that existed 3.9 billion years ago, and search for microfossils in the rocks and soil there.

    NASA's Perseverance rover will complete its seven-month journey to Mars and begin the shortest and by far the most intense stage of its mission: landing.

    Live on Sky News from 8.45pm UK time on Thursday, and in a maximum of seven minutes (although it could take less if something goes wrong), the rover will enter the Martian atmosphere, descend through it, and ultimately land upon the surface.

    One way or another, Perseverance will decelerate from nearly 20,000kmph (12,500mph) - fast enough to get from London to New York in 15 minutes - to being stationary on the planet's surface.

    Excitingly, the mission carries more cameras with it than any other interplanetary mission in history - 19 of them, which will send back breathtaking images of the Martian landscape.

    Four other cameras are attached to the parts of the spacecraft involved in entry, descent and landing, meaning engineers will be able to put together a high-definition view of the landing process, as well as allowing people at home for the first time ever to watch a recording of the landing with raw and processed images.

    After zipping hundreds of millions of miles through space, the Mars rover Perseverance is just hours away from attempting to land on the red planet in what has been described as one of the most daring robotic maneuvers in NASA’s history.

    The car-size rover, which launched in July 2020, is aiming to touch down on Mars on Thursday at around 3:55 p.m. ET. If successful, Perseverance will become NASA’s fifth rover to land on the red planet and will kick off the agency’s most ambitious mission yet to examine whether life ever existed on Mars.

    Perseverance is attempting to answer one of the biggest questions in the history of humanity: Is there life elsewhere in the solar system?” said Chris Carberry, co-founder and CEO of Explore Mars, a nonprofit organization that advocates for human exploration of the planet. “If people can’t get excited about this mission, I don’t know what’s wrong with them.”

    Carberry said the mission could reveal tantalizing new details about Mars’ history and geology. But first, Perseverance has to stick its landing. And that will be no small feat.

    Like its predecessor, Curiosity, the Perseverance rover’s descent to the Martian surface has been dubbed the “seven minutes of terror.” This is because a complex sequence of programmed events must occur at precise times in order for the landing to be successful. And because of limits with deep-space communication, engineers in NASA’s mission control may not be able to follow along in real time.

    “Once it enters Mars’ atmosphere, the entire spacecraft is pretty much acting autonomously,” said Janet Ivey, president of Explore Mars. “You can’t send a message from Earth to divert it from landing on a hill or near a big rock. It’s a nail-biter for sure.”
    The rover is outfitted with a suite of seven tools to study the planet’s geology and past climate. In addition to high-powered cameras, Perseverance is equipped with a drill and robotic arm to collect samples, an instrument to examine the chemical composition of rocks and sediments, a tool to measure weather on Mars and an experiment to test if oxygen can be produced from Mars’ carbon dioxide-rich atmosphere.

    The rover is also carrying a helicopter, known as Ingenuity, that mission controllers will use to attempt the first controlled flights on another planet. The 4-pound drone is designed to fly around and scout out nearby areas in and around Jezero Crater.

    The Perseverance mission is part of a broader NASA initiative with the European Space Agency that aims to collect samples of rocks and sediment from Mars and return them to Earth.

    NASA and the European Space Agency are not the only ones with their sights set on Mars. Earlier this month, separate space probes from the United Arab Emirates and China successfully entered into orbit around Mars, making them just the fifth and sixth nations to do so

  • NASAs rover sends back first images from Mars


    NASA's mission to find signs of life on Mars has beamed back its first images from the surface of the red planet after its rover survived a perilous descent through the thin atmosphere.

    The Perseverance rover survived the 'seven minutes of terror' and successfully landed on Mars after a more than 400-million-kilometre journey which began in July.

    An 11-minute delay meant earth bound engineers had no contact with the rover when it attempted to enter the atmosphere, descend, and land, meaning the sequence had to be completed flawlessly.

    The Perseverance rover landed in the Jezero crater in the planet's northern hemisphere which is thought to have been a lake fed by a river 3.5 billion years ago.

  • 7 Minutes of Terror- Mars Perseverance Rover


    The Mars Perseverance Rover will fly 300 million miles over almost seven months, but the seven minutes spent waiting to receive a radio signal confirming the rover has landed will seem like an eternity for scientists and researchers back on Earth.
    That wait is dubbed the “seven minutes of terror” and Briony Horgan, Purdue University associate professor of planetary science, calls it the scariest moment of the mission.

  • NASA’s Perseverance rover successfully lands on Mars


    NASA’s Perseverance rover has survived the 'seven minutes of terror' and successfully landed on Mars after a more than 400-million-kilometre journey which began in July.

    An 11-minute delay meant earth bound engineers had no contact with the rover when it attempted to enter the atmosphere, descend, and land, meaning the sequence had to be completed flawlessly.

    CSIRO Astronomy and Space’s Glen Nagle told Sky News the landing was a “fantastic moment”.

    “It’s one of those things you can never guarantee that this is going to work … it’s a testament to brilliant engineers, technicians and just dreamers, people that came up with this mission so long ago,” he said.

    “This mission will hopefully unlock the secrets of whether there was ever life on the surface of Mars”.

    Mr Nagle said a piece of Australian rock taken from the Pilbara was placed on board the rover to help the rover know what to look for due to geological similarities to Mars.

    Team members share the challenges of Curiosity's final minutes to landing on the surface of Mars.

  • Touchdown Confirmed! NASA Mars 2020 Perseverance Rover Lands on the Red Planet


    NASA successfully landed its largest and most sophisticated science rover on Mars, as the spacecraft Perseverance touched down in an ancient river delta that may contain signs of whether the planet ever harbored microbial life.

    Cheers erupted at NASA’s Jet Propulsion Laboratory in Pasadena, California, which oversees the agency’s rover fleet, when flight controllers received a signal Thursday at 3:55 p.m. Eastern that the rover had touched down. Perseverance had traveled 292 million miles (470 million kilometers) since launching July 30 from Cape Canaveral, Florida.

    Mars landings are among the toughest challenges in space exploration, and Perseverance’s arrival in Jezero Crater was the trickiest NASA has ever attempted. Strewn by boulders and featuring sand dunes and cliffs as high as 300 feet (about 90 meters), the 28-mile-wide (45 kilometers) crater had been rejected for previous missions. NASA targeted it after advances in terrain-navigation technology enabled the craft to alter its flight path autonomously.

    The $2.7 billion rover also carries a drone helicopter known as Ingenuity with 4-foot rotors, which will be the first craft to attempt to fly on another planet. A successful landing would mean the aircraft could fly as soon as next month, depending on how scientists assess different locations for a flight.

    This is the fifth time since 1997 that the National Aeronautics and Space Administration has attempted a landing on the Martian surface, a daunting task of physics and engineering that comes with a dismal record: More than half of previous efforts have failed in 50 years of attempts. The former Soviet Union is the only other country that has successfully placed a spacecraft on Mars.

    “This is one of the most difficult maneuvers we make in the space business,” Matt Wallace, deputy project manager of NASA’s Mars 2020 mission, told reporters on Wednesday.

    Hitting the Martian atmosphere at 12,000 miles per hour, the spacecraft will have to rapidly decelerate to land at about 2 mph, during what rocket scientists call “seven minutes of terror.” Wallace likened the intricate process to “a controlled disassembly” of the craft to safely disgorge the rover onto the surface.

    Perseverance joins two other NASA missions exploring Mars. The Curiosity rover arrived in mid-2012, and the stationary InSight lander began exploring the planet’s geology in November 2018.

    The 10-foot long Perseverance has nearly the same dimensions as Curiosity, but weighs 278 pounds (126 kilograms) more because of a roughly 50% increase in science payload. Perseverance’s total weight is about 2,260 pounds, and the rover is expected to operate for at least two years.

    Among the vehicle’s new features: more cameras and a microphone to record the sounds of descent and landing.

    NASA's Mars Curiosity Rover closed in on its target today, all systems go for a landing on Mars late tonight (Monday morning at 1:31 a.m. EDT). If there's anxiety at the Jet Propulsion Laboratory in Pasadena, Calif., which controls the mission, one can understand.

    Curiosity (the mission's formal name is Mars Science Laboratory) is the largest, most expensive and most ambitious Mars probe sent by the United States in a generation. It's been a decade in the making and ran up bills of $2.5 billion.

    NASA is playing down expectations, but if the building blocks of life are buried in the Martian soil, Curiosity's miniature onboard chemistry laboratory is designed to pick them out.

    Can we do this? Yeah, I think we can do this. I'm confident, Doug McCuistion, head of the Mars exploration program at NASA headquarters, said Saturday. We have the A-plus team on this. They've done everything possible to ensure success, but that risk still exists.

    Perseverance rover को Mars पर कैसे उतारा गया | 7 minutes of Terror. #nasa

    NASA's Perseverance rover is only a few days away from its daring seven-minute landing on Mars, where it will touch down on the most challenging terrain ever targeted by a Red Planet mission.

    On Feb. 18, the car-size Perseverance — the heart of NASA's Mars 2020 mission — will attempt to land inside the 28-mile-wide (45 kilometers) Jezero Crater. The entry, descent and landing (EDL) phase of a Mars mission is often referred to as seven minutes of terror, because the sequence is so harrowing and happens faster than radio signals can reach Earth from Mars. That means the spacecraft is on its own once it enters the Martian atmosphere — and a gripping new video from NASA shows how the rover will pull off such an amazing feat.

    Space always has a way of throwing us curveballs and surprising us, Swati Mohan, Mars 2020 guidance, navigation and control operations lead at NASA's Jet Propulsion Laboratory (JPL) in Southern California, says in the video. There are many things that have to go right to get Perseverance on to the ground safely.

    The EDL phase begins when the spacecraft reaches the top of the Martian atmosphere and ends with a rocket-powered sky crane lowering Perseverance safely to the surface of the Red Planet. The entire EDL sequence takes roughly seven minutes, during which many crucial steps must take place. The stakes are very high on Thursday for Mars 2020, which will hunt for signs of ancient life and collect samples for humanity's first interplanetary sample-return campaign.

    There is a lot counting on this, Al Chen of JPL, Mars 2020 entry, descent and landing lead, says in the video. This is the first leg of our sample return relay race — there is a lot of work on the line.

    Shortly before reaching the Red Planet, Perseverance will shed its cruise stage, which helped fly the rover to Mars over the last 6.5 months. The next big milestone is atmospheric entry, when the rover will barrel into the Martian skies at about 12,100 mph (19,500 kph).
    The vehicle is equipped with a heat shield that will protect the rover from the intense heat generated during its initial descent and also help slow the spacecraft down. At about 7 miles (11 kilometers) above the surface, the spacecraft will deploy its 70.5-foot-wide (21.5 meters) supersonic parachute — the largest ever sent to another planet, according to the video.

    Soon after, the heat shield will separate and drop away from the spacecraft, exposing Perseverance to the Martian atmosphere for the first time and jumpstarting the vehicle’s Terrain-Relative Navigation system, which is a new autopilot technology that will help guide the rover to a safe landing on Mars.

    Perseverance will be the first mission to use Terrain-Relative Navigation, Mohan says in the video. While it’s descending on the parachute, it will actually be taking images of the surface of Mars and determining where to go based on what it sees. This is finally like landing with your eyes open — having this new technology really allows Perseverance to land in much more challenging terrain than Curiosity, or any previous Mars mission, could.

  • Mars Space Mission: NASAs Perseverance Rover Lands On Red Planet To Look For Signs Of Ancient Life


    The United States has successfully landed its fifth rover on Mars.

    NASA’s Perseverance rover, accompanied by the Ingenuity Mars Helicopter, touched down in Jezero Crater at 2.25 am, 19 February, Indian Standard Time.

    The terrain where the rover settled was the most challenging place to land of any Martian sites previously targeted, because of the presence of steep cliffs, sand dunes, and boulder fields.

    But despite that, the 45-km-wide Jezero Crater, which is named after the small Balkan town of Jezero in Bosnia and Herzegovina, was chosen for its special significance as a possible home for ancient Martian life.

    It is believed that once upon a time a river flowed into a lake here and deposited sediments forming a delta. Though the water may be long gone, hidden in here could be preserved organic molecules and other potential signs of microbial life.

    By getting a closer look, NASA’s most ambitious Mars rover mission yet will hope to learn whether the Red Planet was ever home to life in the 4.6 billion (~460 crore) years of its existence.

    Studying the possible emergence of life on ancient Mars can also help us better understand the conditions that led to life on our own planet,” NASA deputy project scientist Katie Stack Morgan said in the run-up to the historic landing.

    After reaching the top of the Martian atmosphere, the rover descended to the surface after a decisive part of the journey described affectionately as the “seven minutes of terror”, first explained by NASA scientists prior to landing the Curiosity rover on the surface of Mars.

  • NASA rover faces seven minutes of terror before landing on Mars


    By Steve Gorman

    LOS ANGELES (Reuters) - When NASA's Mars rover Perseverance, a robotic astrobiology lab packed inside a space capsule, hits the final stretch of its seven-month journey from Earth this week, it is set to emit a radio alert as it streaks into the thin Martian atmosphere.

    By the time that signal reaches mission managers some 127 million miles (204 million km) away at the Jet Propulsion Laboratory (JPL) near Los Angeles, Perseverance will already have landed on the Red Planet - hopefully in one piece.

    The six-wheeled rover is expected to take seven minutes to descend from the top of the Martian atmosphere to the planet's surface in less time than the 11-minute-plus radio transmission to Earth. Thus, Thursday's final, self-guided descent of the rover spacecraft is set to occur during a white-knuckled interval that JPL engineers affectionately refer to as the seven minutes of terror.

    Al Chen, head of the JPL descent and landing team, called it the most critical and most dangerous part of the $2.7 billion mission.

    Success is never assured, Chen told a recent news briefing. And that's especially true when we're trying to land the biggest, heaviest and most complicated rover we've ever built to the most dangerous site we've ever attempted to land at.

    Much is riding on the outcome. Building on discoveries of nearly 20 U.S. outings to Mars dating back to Mariner 4's 1965 flyby, Perseverance may set the stage for scientists to conclusively show whether life has existed beyond Earth, while paving the way for eventual human missions to the fourth planet from the sun. A safe landing, as always, comes first.

    Success will hinge on a complex sequence of events unfolding without a hitch - from inflation of a giant, supersonic parachute to deployment of a jet-powered sky crane that will descend to a safe landing spot and hover above the surface while lowering the rover to the ground on a tether.

    Perseverance has to do this all on her own, Chen said. We can't help it during this period.

    If all goes as planned, NASA's team would receive a follow-up radio signal shortly before 1 p.m. Pacific time confirming that Perseverance landed on Martian soil at the edge of an ancient, long-vanished river delta and lake bed.


    From there, the nuclear battery-powered rover, roughly the size of a small SUV, will embark on the primary objective of its two-year mission - engaging a complex suite of instruments in the search for signs of microbial life that may have flourished on Mars billions of years ago.

    Advanced power tools will drill samples from Martian rock and seal them into cigar-sized tubes for eventual return to Earth for further analysis - the first such specimens ever collected by humankind from the surface of another planet.

    Two future missions to retrieve those samples and fly them back to Earth are in the planning stages by NASA, in collaboration with the European Space Agency.

    Perseverance, the fifth and by far most sophisticated rover vehicle NASA has sent to Mars since Sojourner in 1997, also incorporates several pioneering features not directly related to astrobiology.

    Among them is a small drone helicopter, nicknamed Ingenuity, that will test surface-to-surface powered flight on another world for the first time. If successful, the four-pound (1.8-kg) whirlybird could pave the way for low-altitude aerial surveillance of Mars during later missions.

    Another experiment is a device to extract pure oxygen from carbon dioxide in the Martian atmosphere, a tool that could prove invaluable for future human life support on Mars and for producing rocket propellant to fly astronauts home.

  • LIVE: NASAs Mars 2020 Perseverance Rover to Land on the Red Planet


    (Feb. 18) A NASA rover streaked toward a landing on Mars on Thursday in the riskiest step yet in an epic quest to bring back rocks that could answer whether life ever existed on the red planet.

    Ground controllers at the space agency’s Jet Propulsion Laboratory in Pasadena, California, settled in nervously for the descent of Perseverance to the surface of Mars, long a deathtrap for incoming spacecraft. It takes a nail-biting 11 1/2 minutes for a signal that would confirm success to reach Earth.

    The landing of the six-wheeled vehicle would mark the third visit to Mars in just over a week. Two spacecraft from the United Arab Emirates and China swung into orbit around the planet on successive days last week.

    All three missions lifted off in July to take advantage of the close alignment of Earth and Mars, traveling some 300 million miles in nearly seven months.

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

    The car-size, plutonium-powered rover was aiming for 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.

    Percy, as it is nicknamed, was designed to drill down with its 7-foot (2-meter) arm and collect rock samples that might hold signs of bygone microscopic life. The plan called for three to four dozen chalk-size samples to be sealed in tubes and set aside on Mars to be retrieved by a fetch rover and brought homeward by another rocket ship, with the goal of getting 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. “Big, basic questions, and we don’t know the answers yet. So 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.

    Perseverance’s descent has been described by NASA as “seven minutes of terror,” in which flight controllers can only watch helplessly. The preprogrammed spacecraft was designed to hit the thin Martian atmosphere at 12,100 mph (19,500 kph), then use a parachute to slow it down and a rocket-steered platform known as a sky crane to lower the rover the rest of the way to the surface.

    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.

    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.

    “The Mars sample return project is probably the most challenging thing we’ve ever attempted within NASA,” said planetary science director Lori Glaze, “and we don’t do any of these things alone.”
