'Seven minutes of terror': NASA's Perseverance will land on Mars TODAY


NASA will today try and land its Perseverance rover on the surface of Mars in a crucial moment for the space agency’s hopes of colonising the red planet.

The descent of the $2.2billion car-sized spacecraft will be live streamed by NASA from 2:15 pm ET (7:15pm GMT) and will show Perseverance trying to endure the so-called ‘seven minutes of terror’.

This refers to the tumultuous conditions which batter the craft as it enters the Martian atmosphere and approaches the surface. 

Temperatures are expected to exceed 2,000°F and a supersonic parachute will be deployed to try and slow the rover down from its entry speed of around 12,000mph — quick enough to travel from London to New York in 15 minutes.

Perseverance, if all goes to plan, will touch down at the base of an 820-foot-deep (250 meters) crater called Jezero, a former lake which was home to water 3.5 billion years ago.  

It will drill into Mars and collect geological specimens that will be cached across the planet and retrieved by a follow up mission around 2031.

The spacecraft carrying the rover will separate ten minutes before atmosphere entry and Perseverance will then enter Mars' atmosphere at around 12,000 miles per hour — quick enough to travel from London to New York in 15 minutes. This rapid speed generates a huge amount of air resistance and friction which warms Perseverance up to an enormous temperature in excess of 2,000°F

Radio signals between Perseverance and NASA take ten minutes to be sent due to the time it takes for the signals to travel all the way to Mars and back again. 

As a result, Perserverence’s on-board computers and 19 cameras are entirely responsible for the descent.

Unlike previous NASA rovers to Mars — Sojourner Spirit, Opportunity and Curiosity — Perseverance is purposely being sent to a more treacherous part of the red planet. 

This is because the Jezero Crater is thought to be an extinct lake and is also close to curious rock formations, all of which are of great scientific interest back on Earth. 

The Jezero crater has been identified as an ideal landing site because of what astronomers have found out about its past.

The massive crater is said to have flowed with water and is littered with carbonates and hydrated silica.

Carbonates located in the crater’s inner rim have been found to survive in fossils on Earth for billions of years and hydrated silica was discovered in the delta that is known for its ability to preserve biosignatures. 

However, the land is littered with uneven surfaces and boulders, making landing and navigation a tricky proposition. 

A parachute is deployed at around four minutes into the descent, when the rover is still seven miles from the surface. NASA says this is a critical step and involves the biggest parachute ever sent to another planet

NASA has sent a number of orbiters to Mars, which allowed them to find Perseverance's target – the 28-mile Jezero Crater (pictured). The Jezero Crater is thought to be an extinct lake and is also close to curious rock formations, all of which are of great scientific interest back on Earth

The first act of Perseverance — which has been based on the blueprint of Curiosity and is the seven feet tall, nine feet wide and weighs 2,260 pounds — will be to release its accompanying Ingenuity helicopter (pictured). The copter will fly at an altitude that is similar to 100,000 feet on Earth, allowing it to gather geology data in areas the rover is unable to reach

NASA’s Ingenuity helicopter preps for its ‘Wright brothers moment’ 

NASA is set to fly where no one has flown before – Mars’ atmosphere.

The American space agency is gearing up to launch its Perseverance rover along with the helicopter after it completes its landing later today.  

Named Ingenuity, the copter will fly at an altitude that is similar to 100,000 feet on Earth, allowing it to gather geology data in areas the rover is unable to travel.

NASA is comparing this mission ‘to the Wright brothers moment,’ as it will be the first time in history an aerial vehicle has flown on another world. 

This will be the first time a terrestrial helicopter has not only flown at such altitudes, but also the first time it will take flight on another planet.

‘Since the Wright brothers first took to the skies of Kill Devil Hills, North Carolina, December 17, 1903, first flights have been important milestones in the life of any vehicle designed for air travel,’ NASA said in a statement

‘It is not guaranteed that we will be successful,’ Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate, said in a statement earlier this week.  

To increase the chance of success, Perseverance is the first mission to be fitted with ‘Terrain Relative Navigation’ which will take images of the martian surface during the descent. The information gathered from this will be used to inform where the rover decides to land. 

Swati Moha, the Navigation and Control Operations Lead on the Mars 2020 mission, said this is ‘finally like landing with your eyes open’.

The spacecraft carrying the rover will separate ten minutes before atmosphere entry and Perseverance will then enter Mars’ atmosphere at around 12,000 miles per hour.

This rapid speed generates a huge amount of air resistance and friction which warms Perseverance up to an enormous temperature in excess of 2,000°F. The brunt of this thermal energy is absorbed by a heat shield, which sits between the rover itself and the outside. 

As it careers through the atmosphere the spacecraft will then continue to guide itself and fly using bursts from on-board jets. 

A parachute is then deployed at around four minutes into the descent, when the rover is still seven miles from the surface. NASA says this is a critical step and involves the biggest parachute ever sent to another planet. 

Once the parachute has reduced the speed to an acceptable level, hefty heat shield is discarded to allow the cameras of Perseverance to begin studying the terrain below. 

At this point the backshell and parachute are also jettisoned when the lander is 1.7miles above the Martian surface.

A landing harness carrying Perseverance which is fitted with eight rocket thrusters then takes control of the descent process and will slow the craft down from 190 miles per hour to a mere 1.7 miles per hour while also steering the lander. 

The craft will then attempt the ‘skycrane’ maneuver which was first developed for Curiosity in 2012.

Nylon cords will hold Perseverance 25 feet below the taxying craft and gently place the rover down n the ed soil of Mars.

At this point, the craft will cut the nylon cords and fly away to ensure it does not damage Perseverance. 

NASA will then attempt to establish a radio connection with the rover and following a momentary pause for either celebration or scomisseratoin, depending on the outcome, Perseverance will begin its work. 

The first act of Perseverance — which has been based on the blueprint of Curiosity and is the seven feet tall, nine feet wide and weighs 2,260 pounds — will be to release its accompanying Ingenuity helicopter. 

The copter will fly at an altitude that is similar to 100,000 feet on Earth, allowing it to gather geology data in areas the rover is unable to reach.

This exceptional height is made possible due to the thin atmosphere on Mars, which is just 1/1,000 as thick as Earth’s. Its two levels of blades will rotate in opposite directions at up to 2,400 rpm.  

Perseverance's primary goal is to look for 'biosignatures' — signs of past or present microbial life — as well as gathering rock samples which will be picked up by another mission in 2026. However, it is equipped with a host of tools which will perform a variety of tasks

UK scientists play key part in NASA mission to red planet 

More than £400,000 in funds from the UK Space Agency Have been provided for the development of Perseverance. 

Researchers at Imperial College London and the Natural History Museum will also be involved in deciding which Martian samples are sent to Earth. 

The research destination is Jezero crater, a 28-mile-wide depression containing sediments of an ancient river delta. At this location, evidence of past life could be preserved. 

The Perseverance rover will gather samples of Martian rocks and soil using its drill. The rover will then store the sample cores in tubes on the Martian surface ready for a return mission to bring around 30 samples to Earth in the early 2030s.

Back on Earth, Professor Sanjeev Gupta from Imperial College London will help NASA oversee mission operations from a science and engineering point of view and Professor Mark Sephton, also from Imperial College London, will be helping to identify samples of Mars that could contain evidence of past life.

Professor Caroline Smith, from the Natural History Museum, will be studying the mineralogy and geochemistry of the different rocks found in Jezero Crater.

Dr Keyron Hickman-Lewis, also from the Natural History Museum, will be studying the environments reflected by sedimentary rocks exposed in Jezero Crater and the potential for the preservation of ancient microbial life within.

Science Minister Amanda Solloway said: ‘The Red Planet has been a source of fascination for centuries, and it is thrilling to be that little bit closer to finding out if there is life on Mars.

‘I am incredibly grateful to the scientists, researchers and engineers involved in this effort from the UK and around the world, and trust that it will inspire a new generation of space scientists across the country.’

Sue Horne, Head of Space Exploration at the UK Space Agency, adds: ‘Over the next few years, our scientists will play a leading role in this international endeavour, from managing science operations to deciding which samples are to be returned to Earth.

‘Perseverance will bring us one step closer to answering the question that’s been on the lips of Bowie fans and scientists for the last forty years.’

This will be the first time a terrestrial helicopter has not only flown at such altitudes, but also the first time it will take flight on another planet. 

NASA is comparing this mission ‘to the Wright brothers moment’ and believes Ingenuity is going to transform how we think about exploring worlds in the future.

Perseverance’s primary goal is to look for ‘biosignatures’ — signs of past or present microbial  life — as well as gathering rock samples which will be picked up by another mission in 2026.

The rover will drill into the dusty surface and gather material into titanium, germ free tubes that will be placed in the vehicle’s belly – there are a total of 43 tubes to fill.

NASA aims to gather at least 20 samples with a variety of material that can be brought back to Earth for further analysis.

NASA has teamed up with the European Space Agency for the follow up mission that would send two or more spacecraft in 2026.

‘In 2026, we’re going to launch a mission from Earth to Mars to go pick up those samples and bring them back to Earth,’ Bridenstine said.

‘For the first time in history, we’re doing a Mars sample return mission.’

All of this is orchestrated by Perseverance 19 cameras and powered by 10.6 pounds of plutonium carried in a custom container roughly the size of a bucket.

The plutonium provides 2,000 watts of thermal power and will last for around 14 years. NASA says.

Other work of Perseverance, which is scheduled to be operational for one Martian year one (687 Earth days), involves investigating if materials found on Mars can be utilised to facilitate return missions. 

This task is called the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) and is preparing for human exploration of Mars.

One goal of MOXIE is to conduct an experiment to convert elements of the carbon dioxide-rich Martian atmosphere into rocket fuel.

NASA is also looking ahead to future crewed missions to Mars and will use Perseverance’s in-built laboratory features to see if breathable oxygen can be created from natural Martian resources.

Once the first pieces of Mars land on Earth, which is expected to happen in 2031, scientists will cut the slabs into thin sheets of rock in order to determine if individual microbial cells are hiding in the samples.

History of NASA landing on Mars  

The Red Planet’s surface has been visited by eight NASA spacecraft and Perseverance – the ninth – will be the first that involves gathering samples to bring back to Earth.

NASA says the mission will also demonstrate key technologies to help prepare for future robotic and human exploration – possibly within a decade.

The first landers to arrive on the Red Planet were Viking 1 and Viking 2, which landed in 1976 to look for signs of life.

Although the technologies provided new insight of the Martian surface, they failed to uncover evidence of life.

NASA’s first Mars rover, Sojourner, landed in 1997.

The agency has sent three others – Spirit, Opportunity and Curiosity – since then.  

NASA also has successfully sent three landers – Pathfinder, Phoenix, InSight.

Perseverance is also fitted with other instruments, including advanced cameras, radar, and a laser.

The rover will use its high-powered laser, called SuperCam, at the top of its mast to shoot high-energy pulses capable of vaporizing rocks up to 20 feet away.

The laser beam heats the target to 18,000 degrees Fahrenheit, which is hot enough to transform the solid rock into plasma that can be imaged by a camera for further analysis.

This instrument will help researchers identify minerals that are beyond the reach of the rover’s robotic arm or in areas too steep for the rover to go.

Although the rover is very similar in design to Curiosity, it has a new array of sensors and equipment, including, for the first time, microphones.

These will record what the entry, descent and landing sounds like, as well as revealing any noises on the surface of Mars.

Perseverance launched on July 30 from Cape Canaveral Florida aboard a United Launch Alliances Atlas V rocket following probes also sent to Mars by the UAE and China. 

The recent spate of launches to Mars is because astronomers are keen to take advantage of a rare alignment in the orbits of Earth and Mars which makes the red planet relatively close and accessible for a period of a few weeks.

The United States has plans to send astronauts to Mars in the 2030s under a program that envisions using a return to the moon as a testing platform for human missions before making the more ambitious crewed journey to Mars.

Earlier this month, the United Arab Emirates become the first Arab nation and only the fifth nation overall to place a spaceship in orbit around Mars.

The country’s space probe, called Hope, officially entered Mars orbit at around 16:15 GMT on February 9, marking the completion of a 493 million km journey from Earth. 

Hope will be the first probe to provide a complete picture of planet’s atmosphere and its layers, according to the UAE. 

China’s orbiter and rover combo – named Tianwen-1 – successfully reached Martian orbit on February 10.

Our 5,000-year obsession with the Red Planet: As NASA’s Perseverance rover touches down today, we reflect on human’s long journey to explore Mars since our ancestors first named their deities for the distant planet

By Stacy Liberatore for DailyMail.com 

NASA’s Perseverance rover is today set to land on Mars to search for signs of life and although the mission has been years in the making, the Red Planet has been part of our culture for thousands of years.

The first record of the Martian world appeared around the third millennium BC, which described it as a god of war and it wasn’t until the mid-1800s did Mars shed its reputation as a deity and become a planet – opening up a world of possibilities.

National Geographic’s Mars issue focuses on ‘Our Obsession With Mars,’ in which it explores how the Red Planet is embedded in our past and what new discoveries Perseverance will uncover during its two-year mission.

‘Kathryn Denning [a doctor of Anthropology at York University in Canada] told me, ‘Mars doesn’t push back all the hard against our imaginations’,’ Nadia Drake, science journalist and space enthusiasts, told DailyMail.com.

‘I think about that and I think about the photos we have from the Martian surface that look so similar to Earth – it isn’t that hard to think about walking across that surface.’ 

NASA’s Perseverance rover is currently speeding through space at 47 miles per hour and is scheduled to touch down at 7:30pm GMT.

Perseverance will spend the next two years hunting for ‘biosignatures’ of past microbial life and collect rock core samples in slender, metal tools that will be cached on the Martian surface to be retrieved in 2026 for a return trip to Earth.

Although the rover is the brainchild of many intelligent and skilled scientists, it may have been the first skygazers who birthed the idea to first visit Mars. 

The Babylonians first spotted a glittering object in the night sky around 400BC, but the ancient civilization never explained what it was, only naming it Nergal the king of conflicts.

Ancient Greeks called the planet Areas, after their god of war, while the Romans  (pictured) gave it the name that has lasted through the ages - Mars

Ancient Greeks called the planet Areas, after their god of war, while the Romans gave it the name that has lasted through the ages, Mars.

From there, Mars transformed into many other deities, but was then recorded as ‘fixed star’ by ancient Egyptian astronomers.

It wasn’t until 1610 when Galileo Galilei conducted the first observation that determined the object to be a planet.

By the mid-1800s, telescopes allowed astronomers to take the first look at Mars’ mysterious terrain, which revealed it had weather, dusty landscapes and ice caps like those on Earth.

‘In the mid-1800s, you could start to see surface features and shifting terrain, and people were really into mapping Mars,’ said Drake.

‘At the time, people were mapping places on Earth to gain control and Mars got caught up in that as well.’

‘They would just draw what they saw. I’ve tried to do it and it is very difficult.’

In 1887, Giovanni Schiaparelli, who was the director of the Brera Observatory in Milan, began mapping and naming areas on Mars.

He saw ‘seas’ and ‘continents’ across the mysterious world, along with channels he called ‘canals.’

Schiaparelli colored areas he believed held water in blue and labeled features on planet after places in Mediterranean mythologies.

Maria Lane, a historical geographer the University of New Mexico, told Drake: ‘That was a really massively bold statement to make.’

‘It’s basically him saying, I saw so much stuff that was so different from what anyone else had seen, I can’t even use the same names.’

Schiaparelli’s maps inspired an astronomer in Boston, Percival Lowel, to build his own private observatory.

Lowell concluded the canals were real after observing hundreds stretched across the Martian landscape and believed they had been created by an intelligent civilization skilled in engineering.

These theories led to the famous ‘War of the World’s novel by H.G. Wells in 1898, which paved the way for an entirely new genre of alien science fiction.

But Lowell’s theories and other fascinating stories about Mars fell apart in 1907, when astronomers took images using telescopes – ‘planetary photography eventually replaces cartography as truth,’ Drake wrote.

And decades later, humans were finally able to see the Red Planet up-close.

NASA sent its Mariner 4 probe into space in 1965, which snapped the first images of the mystifying world.

The black and white images transformed the idea of a watery world home to skilled beings into a grainy, cratered landscape that seemed to without life.

‘Once we sent the first craft in the 1960s we saw nothing of the sort,’ Drake said.

‘It was cratered and looked like the moon, which was very disappointing for people who thought they found signs of life.

‘Then every time we got a sharper and sharper look at mars it looks less likely that it is inhabit.’

NASA followed up Mariner 4 with two Viking missions that landed on the northern hemisphere of Mars in 1967. 

The landers sent back images that were disappointing – no signs of life, no footprints in the dust.

The pictures also revealed the planet’s soil had hints of perchlorates, which are compounds that kill organic molecules and may have erased any signs of life that may have once called Mars home.

‘We’ve always wanted to find life on Mars, but the harder we look the less likely we will find it,’ Drake said.

The obsession with Mars has turned into a race among many nations, which all hope to be the first to discover life.

China launched its Taianwen-1 spacecraft in July 2020, the US followed with NASA’s Perseverance rover just a week later and the United Arab Emirates became the first Arab country to send a spacecraft to Mars this month.

But the highlight for this week is Perseverance, which will endure ‘seven minutes of terror’ Thursday as it descends on Mars for the first time.

NASA MARS 2020: THE MISSION WILL SEE THE PERSEVERANCE ROVER AND INGENUITY HELICOPTER SEARH FOR LIFE

NASA’s Mars 2020 mission will search for signs of ancient life on on the Red Planet in a bid to help scientists better understand how life evolved on Earth. 

Named Perseverance, the main car-sized rover will explore an ancient river delta within the Jezero Crater, which was once filled with a 1,600ft deep lake.

It is believed that the region hosted microbial life some 3.5 to 3.9 billion years ago and the rover will examine soil samples to hunt for evidence of the life.

The $2.5 billion (£1.95 billion) Mars 2020 spaceship launched on July 30 witht he rover and helicopter inside – and will land on February 18, 2021.

Perseverance is designed to land inside the crater and collect samples that will eventually be returned to Earth for further analysis.

A second mission will fly to the planet and return the samples, perhaps by the later 2020s in partnership with the European Space Agency.
