Introduction: A New Era of Space Exploration
the Mars 2020 Mission marks the beginning of a new era in space exploration. NASA's newest rover is designed to uncover some of Mars' most well-kept secrets, and it represents a significant step forward in our quest to understand the Red Planet. The mission's primary objective is to search for signs of ancient microbial life on Mars, but it will also collect data that could help pave the way for future human missions.
The Purpose of the Mission
At its core, the Mars 2020 Mission is all about discovery. NASA scientists hope that by studying Mars' geology and searching for signs of past microbial life, they can gain a better understanding of how planets form and evolve over time. This knowledge could have implications not just for our understanding of Mars, but also for our understanding of Earth and other planets in our solar system.
The Rover: Perseverance
The centerpiece of the mission is Perseverance, a six-wheeled robotic rover that weighs approximately 2,260 pounds (1,025 kilograms). It measures about 10 feet (3 meters) long by 9 feet (2.7 meters) wide by 7 feet (2.2 meters) tall and features advanced scientific instruments capable of conducting groundbreaking research on the Martian surface.
The Landing Site: Jezero Crater
Perseverance will be landing at Jezero Crater on Mars' western edge. This site was chosen because it is believed to have been an ancient lakebed billions of years ago when water flowed freely across its surface. Scientists believe that if there was ever microbial life on Mars, this would have been an ideal location for it to thrive.
Key Objectives
The mission has several key objectives:
- Search for signs or evidence of past microbial life
- Collect samples from areas with high astrobiological potential
- Study the geology and climate of Mars
- Test technologies that could be used for future human missions to Mars

the Mars 2020 Mission has been in development for years, and it will take several months to complete. Here is a rough timeline of what we can expect:
- Launch: July 30, 2020
- Cruise phase: Seven months (July 2020 - February 2021)
- Entry, descent, and landing: February 18, 2021
- Surface operations: One Martian year (687 Earth days)
Inside the Mars Rover: Technologies and Components
Perseverance, NASA's newest rover, is an engineering marvel that features several cutting-edge technologies and components designed to help it complete its mission on Mars. Let's take a closer look at some of the key technologies inside this incredible machine.
Sample Caching System
One of the most important features of Perseverance is its sample caching system, which will allow it to collect and store samples for future analysis. The rover will use a drill to extract rock cores from the Martian surface, then store them in tubes that will be deposited on the planet's surface for pickup by future missions.
Ingenuity Helicopter
Perseverance is carrying another exciting technology onboard - a small helicopter named Ingenuity. This tiny aircraft weighs just 4 pounds (1.8 kilograms) and measures about 19 inches (0.5 meters) tall by 4 feet (1.2 meters) wide when its blades are fully extended. It is designed to fly short distances above the Martian surface, providing valuable data and reconnaissance information during Perseverance's mission.
SuperCam Laser Instrument
SuperCam is an advanced laser instrument that allows Perseverance to analyze rocks from a distance using laser beams and spectroscopy techniques. This instrument can provide detailed information about the chemical composition of rocks without requiring physical contact with them.
Moxie Oxygen Production System
Mars has an atmosphere that consists mostly of carbon dioxide with just trace amounts of oxygen - not enough for humans to breathe or for rockets to propel themselves back into space once they've landed on Mars' surface. To solve this problem, NASA has developed an experimental device called MOXIE (Mars Oxygen In-Situ Resource Utilization Experiment), which can convert carbon dioxide into oxygen through electrolysis.
RIMFAX Radar Instrument
RIMFAX stands for "Radar Imager for Mars' Subsurface Experiment." This advanced instrument uses ground-penetrating radar to study the subsurface structure of Mars, allowing Perseverance to see beneath the planet's surface and identify potential sites for future exploration.
PIXL X-Ray Spectrometer
The Planetary Instrument for X-ray Lithochemistry (PIXL) is an advanced spectrometer that uses x-rays to analyze the elemental composition of rocks on Mars. PIXL can determine which elements are present in a given sample, providing valuable information about the geological history of Mars and its potential habitability.
Navigation Cameras
Perseverance has 23 cameras onboard, including several navigation cameras that are used to help the rover navigate across the Martian surface. These cameras provide high-resolution images of Perseverance's surroundings, allowing mission scientists and engineers to make informed decisions about where to send the rover next.
The Journey Ahead: Challenges and Milestones
the Mars 2020 Mission is a complex and ambitious undertaking that will require NASA to overcome a number of challenges along the way. From the journey to Mars to the landing process, let's take a closer look at some of the key milestones and obstacles that lie ahead.
Launch
The first hurdle for NASA is getting Perseverance off the ground. The rover was launched on July 30, 2020, aboard an Atlas V rocket from Cape Canaveral Air Force Station in Florida. The launch had to be timed just right so that Perseverance would arrive at Mars when it was closest to Earth in its orbit.
Journey to Mars
After launching from Earth, Perseverance will spend seven months traveling through deep space before arriving at Mars. During this time, it must navigate through space debris and avoid collisions with other objects while maintaining its course towards its destination.
Entry, Descent, and Landing (EDL)
Perhaps one of the most challenging aspects of any mission to Mars is successfully landing on the planet's surface. This process involves several stages:
- Entry: The rover enters Martian atmosphere at speeds exceeding 12,000 mph (19,000 kph). Friction with air molecules slows it down.
- Parachute deployment: About six miles above Martian surface (10 km), a parachute deploys and slows down descent.
- Heatshield release: After slowing down even more due to friction with air molecules perpendicular surfaces heat up; once slow enough heat shield releases.
- Powered descent: A rocket-powered "sky crane" lowers Perseverance onto Martian surface safely.
This entire sequence takes less than seven minutes but has been dubbed by NASA as "seven minutes of terror."
Surface Operations
Once safely landed on the Martian surface inside Jezero Crater - where ancient microbial life may have lived - Perseverance will begin its scientific mission. The rover has a minimum expected operational life of one Martian year (687 Earth days), and during that time, it will use its advanced scientific instruments to study the geology, atmosphere, and potential habitability of Mars.
Sample Return Mission
One of the most exciting aspects of the Mars 2020 Mission is its sample caching system. Perseverance will collect rock samples from the Martian surface for future analysis by other missions. NASA plans to send another mission in 2026 called "Mars Sample Return" to retrieve these samples collected by Perseverance and return them back to Earth so scientists can conduct more detailed analysis.
Unlocking the Mysteries of the Red Planet: Scientific Goals and Objectives
the Mars 2020 Mission is primarily a scientific mission, and it has several key goals and objectives that NASA hopes to achieve during its time on Mars. From searching for signs of ancient life to studying the planet's geology and atmosphere, let's take a closer look at some of these scientific objectives.
