Chapter 6: Milestones in Mars Exploration

The history of Mars exploration is filled with challenges and breakthroughs. Since the 1960s, humanity has sent multiple probes and rovers to Mars. These missions have not only revealed Mars's surface features but also discovered evidence of water existence, supporting the theory that Mars may be suitable for life. Early Mars exploration missions included Mariner 4, Mariner 9, and the Viking program, which provided the first photographs and data of the Martian surface. Entering the 21st century, with technological advances, orbiters such as Mars Odyssey, the Mars Reconnaissance Orbiter (MRO), and Mars Express provided higher-resolution images and data of the Martian surface. Rovers such as Spirit, Opportunity, and Curiosity conducted detailed studies of the Martian surface and geology, further confirming the historical presence of water on Mars. In 2021, NASA's Perseverance rover successfully landed in Jezero Crater, primarily searching for signs of ancient microbial life and collecting rock samples for future return to Earth. Meanwhile, China's Tianwen-1 mission successfully deployed the Zhurong rover, marking China's first successful Mars landing and making China the second country to successfully operate a rover on Mars. These milestones not only demonstrate humanity's growing Mars exploration capabilities but also lay the groundwork for future crewed Mars missions and the establishment of Mars bases. In the future, with further technological advances and international cooperation, humanity is expected to achieve crewed Mars landings in the coming decades, ushering in a new era of Mars exploration and development.
