Sixty years ago, NASA’s Mariner 4 sent home incredible images of Mars, changing how we see the planet. In 1965, it was the first mission to capture photos of another planet. The spacecraft took 21 images during its flyby, showing a crater-filled surface from about 6,118 miles away. The team was so eager to see the results that they even created a color-by-numbers version while waiting. When the real images arrived, they revealed a barren landscape that sparked curiosity for decades to come.
Since then, millions of photos have been taken, each one unlocking new mysteries of Mars:
July 20, 1976
Viking 1 was the first spacecraft to land on Mars. Its initial high-resolution images showed a rocky terrain, dashing hopes for finding life. But the clearer images that followed provided valuable scientific insights and excitement about future missions.
1980
Viking 1 orbited the planet before landing, capturing images that mapped parts of Mars, including the stunning Valles Marineris, often called the “Grand Canyon of Mars.”
July 5, 1997
By 1997, the Pathfinder lander and its rover, Sojourner, landed on Mars. With the rise of the internet, people could follow the mission closely. The panoramic images from this mission set the stage for more detailed explorations.

In 2004, NASA’s Spirit and Opportunity rovers landed, marking a new era of exploration. Equipped with advanced cameras, they captured colorful images of Martian terrain, making Mars feel like a more familiar place.

Since Viking, new orbiters with better cameras have mapped Mars in detail. The High-Resolution Imaging Science Experiment (HiRISE) on the Mars Reconnaissance Orbiter has been particularly insightful, capturing high-quality images that reveal the planet’s surface features.
Aug. 5, 2012, and Feb. 18, 2021
Curiosity and Perseverance rovers landed in 2012 and 2021, respectively, armed with cutting-edge imaging technology. These rovers produced stunning images and detailed analyses of the Martian surface, providing insights into its geology and climate.

Perseverance also carried the Ingenuity helicopter to Mars. Ingenuity proved that flight is possible in the thin Martian atmosphere and provided unique aerial views, paving the way for future aerial explorations.
Expert opinion underscores the significance of these missions. Dr. Jim Bell, a planetary scientist, observes, “The technology improvements have enhanced our understanding of Mars’ surface, climate, and potential for life.”
According to recent data, interest in Mars missions has surged, with surveys indicating that 68% of Americans support funding for space explorations. This growing interest reflects a shift towards a more ambitious approach to exploring not just Mars, but space as a whole.
As we remember these historical moments, the evolution of Mars exploration serves as a reminder of human curiosity and innovation. Each image taken expands our understanding of our neighboring planet, reminding us of how far we’ve come and the discoveries still to be made.
