NASA launched

Its Mars 2020 Perseverance rover mission today from Cape Canaveral Air Force Station, Florida. The rover will spend at least 1 Martian year (equivalent to roughly 2 Earth years), exploring the landing site region


ROVER NAME :Perseverance

The PERSEVERANCE ROVER weighs under 1043 kg.built on technology developed for its predecessor ,curiosity.equipped with cutting-edge instruments and 23 cameras .It will touch down on mars on feb 18,2021 .It will land in Jezero Crater region , thought to be an ancient river Delta

The Mission costs $2.7 billion, and equipped with a new technology terrain -relative navigation to allow the spacecrafts to avoid hazards autonomously

PERSEVERANCE ROVER also carrying a helicopter ,named INGENUITY in its belly.

its weighs 1.8 kg ,is equipped with a wireless communication system

and solar-powered batteries to carry out has internal heaters to maintain temperature during cold nights on mars.

equipped with two cameras for keeping track of where it is and a colour one for oblique views of the landscape.about two months after perseverance lands,it will release ingenuity on a flat ,obstruction-free area. Ingenuity will fly at an altitude that is similar to 100,000 ft on earth and drive at least 300 ft so that the helicopter can take off,and gather geological data from areas where the rover can't go.


The mission has four main objectives:

1- Seeking signs of ancient life

2- Collecting rocks and soil samples for

possible return to earth.

3- Identifying past environments capable of supporting microbial,life.

4- Testing oxygen production on the martian atmosphere

Searching for Ancient Life, Gathering Rocks and Soil

There are several ways that the mission helps pave the way for future human expeditions to Mars and demonstrates technologies that may be used in those endeavors.

These include testing a method for producing oxygen from the Martian atmosphere, identifying other resources (such as subsurface water), improving landing techniques, and characterizing weather, dust, and other potential environmental conditions that could affect future astronauts living and working on Mars.

Technologies for Entry, Descent, and Landing

The mission uses technological innovations already demonstrated successfully, especially for entry, descent, and landing (EDL). Like NASA's Curiosity rover (Mars Science Laboratory mission), the Mars 2020 spacecraft uses a guided entry, descent, and landing system. The landing system on the Mars 2020 mission, as with Curiosity, includes a parachute, descent vehicle, and an approach called a "sky crane maneuver" for lowering the rover on a tether to the surface during the final seconds before landing.

This type of landing system provides the ability to land a very large, heavy rover on the surface of Mars in a more precise landing area than was possible before Curiosity's landing. Mars 2020 takes things one step further. It adds new entry, descent, and landing (EDL) technologies, such as Terrain-Relative Navigation (TRN). This sophisticated navigation system allows the rover to detect and avoid hazardous terrain by diverting around it during its descent through the Martian atmosphere. A microphone allows engineers to analyze entry, descent, and landing. It might also capture sounds of the rover at work, which would provide engineers with clues about the rover's health and operations, and would be a treat to hear.

Technologies for Surface Operations

The Perseverance rover design minimizes costs and risks because it is largely based on the engineering design for the previous Curiosity rover. The Perseverance long-range mobility system allows it to travel on the surface of Mars over 3 to 12 miles (5 to 20 kilometers). Improvements on Perseverance include a new, more capable wheel design. And for the first time, the rover carries a drill for coring samples from Martian rocks and soil. It gathers and stores the cores in tubes on the Martian surface, using "depot caching." Caching demonstrates a new rover capability of gathering, storing, and preserving samples. This could potentially pave the way for future missions to retrieve the samples and ferry them to Earth for intensive laboratory analysis.

Perseverance will test a technology for extracting oxygen from the Martian atmosphere, which is 96% carbon dioxide. This demonstration helps mission planners test ways of using Mars' natural resources to support human explorers and improve designs for life support, transportation, and other important systems for living and working on Mars. The rover also monitors weather and dust in the Martian atmosphere. Such studies are important for understanding daily and seasonal changes on Mars, and will help future human explorers better predict Martian weather.

NASA'S Perseverance is the latest in succession of its wheeled explorers sent to mars since 1997.

Apart from NASA, THE UAE and CHINA have also sent their missions to mars this month.
