The First Steps: Early Attempts to Explore Mars
Mars has fascinated humans for centuries. Our neighboring planet has been a source of inspiration, curiosity and wonder, fueling our imagination with stories of alien civilizations, red deserts and futuristic colonies. But the history of Mars exploration is also one of daring missions, cutting-edge technology and scientific breakthroughs that have helped us understand more about our place in the universe.
The First Observations: From Ancient Civilizations to Galileo
The first attempts to explore Mars date back to ancient times when civilizations like the Babylonians and Egyptians observed its movements in the sky. Later on, Greek astronomers like Aristotle and Ptolemy studied its orbit and position relative to Earth. However, it wasn't until the invention of the telescope that we were able to see more details about Mars' surface features.
In 1610, Galileo Galilei was among the first astronomers to observe Mars through his telescope. His drawings showed dark spots which he believed were seas or continents on the planet's surface. However, these observations were later proven inaccurate as they were likely caused by imperfections in his telescope or his own interpretation.
The Golden Age of Martian Exploration: From Percival Lowell to Mariner Missions
The late 19th century marked a new era in Martian exploration thanks to astronomer Percival Lowell who claimed he had discovered evidence of canals on its surface suggesting an advanced civilization. This sparked public interest and led many astronomers around the world including Giovanni Schiaparelli (who coined terms such as "oasis" "mare" for features on mars), Camille Flammarion (who wrote detailed books popularising martian science) ,and Eugene Antoniadi (who refined telescopic observing techniques) made detailed observations using telescopes They all reported seeing lines or channels but they did not suggest any intelligent life form like Lowell did..
However early unmanned missions like Mariner 4,6 and 7 in the 1960s that flew by Mars revealed a different story. Instead of canals and oceans, scientists found a barren, rocky landscape with a thin atmosphere consisting of mostly carbon dioxide. The Mariner missions provided vital information about atmospheric pressure, surface temperature and mineral composition which paved the way for future exploration.
Landing on Martian Soil: From Viking to Curiosity
The first successful landings on Mars were achieved by NASA's Viking mission in the mid-1970s. Two spacecraft landed on opposite sides of the planet carrying an array of scientific instruments including cameras, spectroscopes and soil analyzers. The data collected from these experiments helped us understand more about Mars' geology and climate.
Subsequent missions such as Pathfinder/Sojourner , Spirit/Opportunity (Mars Exploration Rovers) conveyed human made rovers to mars surface enabling them to explore large areas than ever before . These rovers were equipped with powerful cameras that took stunning images of the Martian terrain along with geological tools that analyzed rocks for signs of water or organic compounds.
The most recent mission to land on Martian soil was NASA's Curiosity rover which arrived in August 2012.It carried an advanced suite of scientific instruments including lasers spectrometers among others designed to search for signs that Mars could have supported life at some point in its history. Its discoveries suggest there was once an environment suitable for microbial life billions years ago.
The Golden Era: The Triumphs and Failures of 1960-1970s Missions
The 1960s and 1970s were a time of great progress in space exploration. It was during this period that several missions were launched to explore Mars, marking the beginning of a new era in planetary science.
###The First Attempts: Mariner 3 and Mariner 4
In November 1964, NASA launched the Mariner 3 spacecraft, which was intended to fly by Mars and take pictures. However it malfunctioned soon after launch and failed to reach mars.
Mariner IV proved more successful, flying by Mars on July 14th ,1965. It's TV camera system returned the first ever close-up images of another planet taken from space despite being only able to capture images every few seconds . The photos revealed a cratered landscape similar to our Moon's with no signs of water or life.
###The Soviet Union's Failed Missions: Marsnik Program
While NASA achieved success with their early missions, the Soviet Union suffered several setbacks during their attempts at exploring Mars as part of their "Marsnik" program. In October and November of 1962 they launched two spacecraft which unfortunately failed before they could even leave Earth orbit due to launch vehicle malfunctions..
###Viking Landers: Paving Way for Future Exploration

Two separate landers were successfully placed on opposite sides (June/July ,20th - August/September ,3rd)of mars by separate landing vehicles carrying scientific experiments designed specifically for long-term studies on martian soil like testing for microbial life through labelled release experiments .
One major discovery made by these probes was that there wasn't any evidence found for microbial life but rather an environment hostile towards it . They also studied atmospheric composition as well as geological structures and found evidence of ancient riverbeds suggesting that liquid water may have once existed on the planet's surface.
However, it was not until the 1990s that a series of missions would be launched to explore Mars in greater detail including such as Global Surveyor, Mars Odyssey and Mars Express among others.
###Mars Exploration Rovers: Spirit and Opportunity
In 2004 , NASA's twin rovers Spirit & Opportunity landed on opposite sides of mars. These rovers were designed to conduct extensive geological surveys as well as search for signs of past or present life on the planet. They explored large areas over several years discovering a wealth of information about Martian geology including the fact that liquid water had once existed in some locations.
