NASA's Perseverance rover has spent the last week on the surface of Mars and in that short time has already sent back thousands of photos - including a cheeky selfie.

The latest rover from the US space agency landed on the Red Planet just before 21:00 GMT on Thursday, February 18 after a hair raising '7-minutes of terror'.

The $2.2 billion vehicle is equipped with 23 cameras including nine for engineering work, seven for science and seven to help it land on the Martian surface.

The first image sent back from Mars was a grainy, dust covered black and white picture taken by one of the Navigation Cameras and shows rocks of various sizes littering the Jezero crater.

Among the most iconic images sent back was the rover dangling over the Martian surface, attached to the sky crane that helped it safely land on the Red Planet.

Other images returned include a sensational high resolution 360-degree panorama of the Martian landscape and a video of Perseverance's nail biting landing.

The cameras on Perseverance all serve multiple purposes, beyond simply sending back images showing the landscape, sunrise, sunset and skyline of another world.

The space agency said the rover's cameras will help scientists assess the geologic history and atmospheric conditions of Jezero Crater and identify rocks and sediment worthy of a closer examination and collection for eventual return to Earth.

NASA PERSEVERANCE CAMERAS 

There are 23 cameras mounted to the Perseverance rover including:

Nine engineering cameras, seven science cameras and seven for entry, descent and landing. 

The engineering cameras give detailed information in colour about the terrain the rover has to cross.

They measure the ground for safe driving, check out the status of hardware and support sample gathering.

There are HazCams for hazard detection and Navcams for navigation.

Science cameras record in more detail and can even capture 3D images.

The Mastcam-Z on a 2 metre arm has a zoom feature for focusing on distant objects and can film video.

The Supercam fires a laser at mineral targets beyond the reach of the rovers arm to analysed the chemical composition of the rock. 

The camera system can reveal details as small as 3 to 5 millimetres across near the rover and 2 to 3 meters across in the distant slopes along the horizon.

The majority of cameras on the vehicle are designed for engineering use, and they give detailed information - in colour - about the terrain the rover has to cross.

They measure the ground for safe driving, check out the status of hardware on the vehicle for analysis and support sample gathering - a core mission objective.

There are HazCams for hazard detection and Navcams for navigation, cameras that shoot lasers and those that film video or capture 3D views.  

So far the majority of images have come from the various entry, descent and landing camera - including those looking at the parachute, descent stage and rover.

There are more than 4,625 images taken by the landing and descent cameras, with about 600 coming from the left and right science 'Mastcam-Z'. 

This makes sense given we are only a week into a mission that could last more than a decade, capturing hundreds of thousands of images, videos and audio files.

For comparison, NASA Curiosity, the rover that has been on Mars since 2012, has captured almost 400,000 images of the Red Planet from fewer cameras. 

Mastcam-Z's design is an evolution of NASA's Curiosity Mars rover's Mastcam instrument, which has two cameras of fixed focal length rather than zoomable.

The two cameras on Perseverance's Mastcam-Z dual cameras are mounted on the rover's mast at eye level for a person 2 meters tall. 

They sit 24.1 centimeters apart to provide stereo vision and can produce colour images with a quality similar to that of a consumer digital HD camera.  

A number of sensational images, video and even audio clips have already been shared of the Red Planet from Perseverance's array of cameras and equipment.

These included a hair raising video showing the '7-minutes of terror' the rover went through as it descended through the Martian atmosphere to land in the crater.

The first image NASA shared from Mars, sent minutes after the vehicle landed on the Red Planet, was a grainy black and white picture through the fish eye lens of the Perseverance Hazard Cameras.

The dust obscured image showed the baron, rock covered landscape of the Jezero crater with shadows of the Perseverance rover in the foreground and the Martian sky in the background.

The image came in while mission control crew were still celebrating the successful landing in the 28-mile wide crater that was picked as a promising target for finding ancient life signs.

Perseverance will make oxygen on Mars  

The primary task for Perseverance is to search for signs of microbial life and take soil samples, but it will also conduct a host of other jobs during its operational window of one Martian year one (687 Earth days).

One of these, for example, involves investigating if Mars' natural resources can be turned into oxygen to make breathable air for astronauts and also to make rocket fuel for return missions. 

This task is called the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE).

Future crewed missions to Mars will require oxygen for astronauts to breathe. Carrying  oxygen from Earth to Mars is heavy and expensive.

MOXIE is designed to see if it is possible to extract oxygen from Mars and turn it into breathable air. 

Mars atmosphere is more than 95 per cent of carbon dioxide and less than 0.15 per cent oxygen. 

Moxie will take Martian air, heat it to 800°C, inject energy into a pair of electrodes and this then separates oxygen from the CO2.

Oxygen is pumped out of one line and waste gase are spewed out of another.  

The first colour image from Perseverance came from the Hazard Camera photo, soon followed by a look down from the sky crane that placed the rover on the surface, showing the rocks and soil as the rover approached.

The sky crane manoeuvre is the final landing stage that was also used when Curiosity landed on Mars in 2012.

The detailed image, which could become an iconic image in spaceflight shows the long Nylon cords lowering Perseverance to the Martian surface, along with the rover's mechanics and wheels dangling in the air.

This is something we've never seen before,' said Aaron Stehura, NASA flight system engineer, describing himself and colleagues as 'awe-struck' when first viewing the image.

'You are brought to the surface of Mars. You're sitting there, seven meters off the surface of the rover looking down,' he said. 'It's absolutely exhilarating, and it is evocative of those other images from our experience as human beings moving out into our solar system.'

After the first image they came in a flurry's , including a close up of the wheel tracks on Perseverance, taken by the colour Hazard Cameras.

It wasn't just pictures taken by Perseverance that captured the imagination. The HiRISE camera on the Mars Reconnaissance Orbiter flying above Mars. It showed the descent stage holding Perseverance. 

One of the most recent images was a sensational 360-degree panorama taken by the Navcams stitched together from six individual images after they were sent back to Earth. 

It showed the deep rust-coloured orange of the Martian surface, looking towards the horizon with a light orange/pink tinged sky and a large looking Sun in the distance. 

Other panorama images show the deck of the Perseverance with the equipment used to search for signs of long gone Martian microbial life and a sweeping panoramic view taken by the Mastcam-Z instrument.

This was the first panorama from the science camera and shows rubble like rocks in the foreground, with sweeping hills in the background, looking towards the rim of the Jezero crater. 

Within the images was one of a wind carved rock with strange angles, showing the level of detail possible in the zoomable Mastcam-Z cameras on the rover.

 The stunning panorama was created with 5,000 commands parameters that shot a total of 142 images that were beamed back to Earth where NASA stitched them together.

While the image may seem like a barren landscape, taking a closer look through the area reveals a number of hidden gems waiting to be investigated by Perseverance.

To the left of the rover sits an interesting rock that NASA has named 'harbor seal' that was formed by Martian winds eroding it for billions of years and northeast of the rover are structures littering the ground that could have came from an ancient volcano. 

More images are being shared all the time, with more than 5,600 raw images already shown on the Perseverance page - including bright red shots of the surface.

A key objective for Perseverance's mission on Mars is astrobiology, including the search for signs of ancient microbial life. 

The rover will characterise the planet's geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith.

Subsequent missions, currently under consideration by NASA in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these cached samples from the surface and return them to Earth for in-depth analysis.
