Mars Exploration Enters a New Era of Science and Discovery
Mars is a fascinating world that has captivated the imagination of scientists and explorers for centuries. The Red Planet offers clues about the origin and evolution of our solar system, as well as the potential for life beyond Earth.
In recent years, Mars has become a busy destination for robotic missions from various countries and agencies. These missions are laying the scientific groundwork for a new era of exploration at Mars, one that could eventually involve human explorers.
One of the most ambitious missions currently operating on Mars is NASA’s Perseverance rover1, which landed in February 2021 in Jezero Crater, an ancient lakebed that may have once harbored microbial life. Perseverance is collecting rock and soil samples that will be returned to Earth by future missions for detailed analysis. The rover is also carrying a small helicopter called Ingenuity1, which has demonstrated the first powered flight on another planet.
Another milestone mission is China’s Tianwen-12, which arrived at Mars in February 2021 and deployed a lander and rover in May 2021. The lander carried a camera, a magnetometer, and a ground-penetrating radar to study the Martian surface2. The rover, named Zhurong after an ancient fire god, carried six scientific instruments to investigate the geology, climate, and environment of Utopia Planitia2, a large plain where water ice may be buried.
Other missions that are currently orbiting or landing on Mars include ESA’s ExoMars Trace Gas Orbiter3, which is searching for traces of methane and other gases that could indicate biological or geological activity; India’s Mars Orbiter Mission4, which is studying the Martian atmosphere and surface features; UAE’s Hope Probe3, which is measuring the global weather patterns and climate dynamics of Mars; NASA’s InSight lander5, which recently ended its mission after more than four years of probing the deep interior of Mars; and NASA’s Curiosity rover1, which is exploring Gale Crater and Mount Sharp.
These missions are not only advancing our scientific knowledge of Mars, but also preparing us for future exploration challenges. For example, they are testing new technologies such as autonomous navigation, laser communication, sample caching, and entry-descent-landing systems. They are also identifying potential landing sites, resources, hazards, and opportunities for human exploration.
The next decade will see even more exciting missions to Mars, such as NASA’s Icebreaker Life mission planned for 20266, which will drill into ice-cemented ground to search for evidence of life; ESA’s ExoMars Rosalind Franklin rover planned for 20233, which will drill up to two meters deep to collect samples; Japan’s Martian Moons Exploration mission planned for 20242, which will orbit around Phobos and Deimos and return samples from Phobos; Russia’s Boomerang mission planned for 20302, which will land on Phobos and return samples; SpaceX’s Starship vehicle planned for 2030s2, which will carry cargo and crew to Mars; NASA’s Artemis program planned for 2030s1, which will establish a sustainable presence on the Moon as a gateway to Mars; and many more.
Mars exploration is entering a new era of science and discovery that will reveal more secrets about our neighboring world. As we continue to explore this fascinating planet with robots and humans alike, we may find answers to some of our most profound questions: How did life originate in our solar system? Is there life elsewhere in the universe? What is our destiny as a species?

Mars is the fourth planet from the sun in our solar system, named after the Roman god of war. It is often referred to as the "Red Planet" because of its reddish appearance in the night sky. Mars has been of interest to humans for centuries, and it has been the subject of numerous scientific studies and missions.
Here are some key facts about Mars:
Mars is about half the size of Earth, with a diameter of approximately 4,212 miles (6,779 kilometers).
The atmosphere on Mars is much thinner than Earth's, with a surface pressure only about 1% of that on Earth.
The temperature on Mars can vary greatly, with an average temperature of about -80 degrees Fahrenheit (-62 degrees Celsius).
Mars has two small moons named Phobos and Deimos, which are believed to be captured asteroids.
Mars has a complex geology, with evidence of ancient volcanoes, canyons, and other geological features.
Mars is home to the largest volcano in the solar system, Olympus Mons, which stands about three times taller than Mount Everest.
There is evidence of water on Mars, including frozen water at the poles and signs of ancient rivers and lakes.
Mars has been the subject of numerous space missions, including the ongoing Mars Exploration Program by NASA, which aims to explore the planet's geology, atmosphere, and potential for life.

Mars, also known as the Red Planet, has always been an object of fascination for scientists and space enthusiasts alike. With several missions to the planet over the years, scientists have been able to uncover a wealth of information about its history, geology, and potential for supporting life. In this article, we will discuss some of the latest developments and discoveries on Mars.
NASA's Perseverance Rover
One of the most exciting developments in Mars exploration is NASA's Perseverance rover. Launched in July 2020, the rover landed on Mars on February 18, 2021, in the Jezero Crater. This mission is focused on searching for signs of ancient microbial life on the planet and collecting samples of the Martian soil and rocks for future analysis.
One of the most significant achievements of the Perseverance mission was the successful flight of the Ingenuity helicopter, which took place on April 19, 2021. This marked the first time a powered, controlled flight had taken place on another planet, and it opens up new possibilities for future exploration.
Exploring the Jezero Crater
The Jezero Crater, where the Perseverance rover landed, is a particularly interesting area of Mars because it is believed to have been a lake bed in the distant past. Scientists believe that the crater was once filled with water, and that the river delta visible in the area may contain signs of ancient life.
Since landing on Mars, the rover has been exploring the area, taking high-resolution images and using its suite of scientific instruments to study the rocks and soil. In early September 2021, the rover successfully drilled its first rock sample from the Martian surface, which will be analyzed for signs of ancient microbial life.
Other Recent Discoveries
In addition to the Perseverance mission, there have been several other recent discoveries related to Mars. In August 2021, scientists announced the discovery of a previously unknown type of mineral on Mars, which was found in a meteorite that originated from the planet. The mineral, called Edscottite, had previously only been found on Earth and in other meteorites.
Another exciting development is the Mars Sample Return mission, which is a joint project between NASA and the European Space Agency. The mission is set to launch in 2026 and will involve collecting samples of Martian soil and rocks and returning them to Earth for analysis. This will be the first time that samples from Mars will have been brought back to Earth, and it could provide valuable insights into the planet's history and potential for supporting life.
