NASA's Perseverance Rover, affectionately named Percy, released the tenth and last sample tube on Wednesday, marking the completion of the first 'sample depot on another globe.' The sample tube will be kept in a warehouse together with other potential samples for the Mars Sample Return Campaign.

On December 21st, the Perseverance Rover delivered the first sample, and by the end of the month, the depot was complete. Titanium tubes containing Martian dirt and rock are scattered throughout the planet in a zigzag pattern, with five to fifteen metres of space between each tube. The depot is situated on flat ground close to a fan-shaped former river delta, and the Perseverance team has meticulously documented the location of each tube to ensure they can be located even if they get hidden by dust.

Exactly what is the Mars Rover Perseverance?

About 3 metres in length, 2.7 metres in breadth, and 2.2 metres in height, the NASA Perseverance rover on Mars is a relatively compact space exploration vehicle. It weighs only about 1,025 kg even when packed to the gills with instruments and is about the size of a car. It has similar parts to those found in mammals that aid in adaptation and survival because it must operate independently on the surface of a plant millions of kilometres distant.

The physical structure of its body protects its 'sensitive insides,' while the network of computers inner it serves as its 'brain' and central processing unit. Its 'eyes' are the cameras and other sensors that allow it to see and 'ears' that allow it to hear the world around it. Its mobility is enabled by wheels, which function as its 'legs.'

When did you begin your tenacity?

Hold fast to the July 30, 2020, launch of an Atlas V-541 rocket from Launch Complex 41 at Cape Canaveral Air Force Station. On February 18, 2021, the Ingenuity Mars Helicopter successfully landed on the red planet.
The mission of NASA's Perseverance rover

Despite setbacks, the crew continues their quest for signs of life on Mars. NASA probes have found evidence that Mars once had flowing water before it turned into a frozen desert. Conditions on Mars' warmer surface might have been favourable for microbial life.

The existence or nonexistence of microbial life on Mars is one of the most serious concerns in astrobiology, and this is the subject that will be tackled by the team determined to find the answer. It's possible that biosignatures of once-living microbes can be found in the Jezero Crater.

This 45-kilometer-wide crater is located in the northern hemisphere of Mars. According to NASA, a river emptied into the sea 3.5 billion years ago. The space agency believes that the organic compounds and other forms of microorganism life were preserved in the former river delta.
How do we get samples back from Perseverance?

Many scientific instruments are built within the Perseverance rover to facilitate in-depth studies of Mars. Organic matter and minerals can be detected by the PIXL (Planetary Instrument for X-ray Lithochemistry) and SHERLOC (Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals), respectively.

No matter how precise those devices are, only sophisticated research facilities on Earth can delve deeply into the mysteries of Mars. For this reason, it is imperative that rovers bring Earth samples back with them. How?

Mission to Bring Samples Back from Mars. The first mission to return samples from another planet and launch from another globe will be conducted by NASA and the European Space Agency (ESA).

In 2023, a NASA-led Mars rocket will carry a Sample Retrieval Lander and two Ingenuity-style tiny Mars helicopters to the red planet. Jezero Crater, close to the town of Perseverance, was the spot it touched down. The rover Perseverance would use a robotic arm to transfer the samples from Percy to the rocket of the lander once the lander touched down.

Data from the rover will be corroborated by Martian samples collected by the Perseverance. The samples from Perseverance will be recovered by the two helicopters of the retrieval lander, which will then return to the lander to be loaded onto rockets.
