The mystery of life on Mars has long been a significant topic of exploration within the scientific community. As early as the late 19th century, American astronomer Percival Lowell discovered canal-like features on the Martian surface, sparking curiosity about the possibility of life on the planet. Starting in the 1960s, the United States and the Soviet Union launched extensive Mars exploration programs. From Mariner 4 to Viking and Mars Pathfinder, each mission has provided valuable clues in the quest to unravel the mystery of life on Mars. Although early explorations did not directly find signs of life, scientists have speculated that liquid water—and possibly life—may have existed on Mars by analyzing soil samples and geological structures. With advancements in technology, scientists believe that the truth about life on Mars may soon be revealed.
