Mars Was Observed in Ancient Egyptian Times
Ancient Egyptian astronomers observed Mars despite how far away it was from Earth and noted it as a roving object in the sky. They were aware of the planet's retrograde motion by 1534 BC. As the number of sightings of the planet increased in detail, Galileo Galilei performed the first telescopic observation in 1610. Astronomers soon discovered unique characteristics of our neighboring planet, such as its polar ice caps, rotational period, and axial tilt.
Then, in the 19th century, larger telescopes enabled better views, and soon it was being detailed chart. They have dispatched numerous robotic spacecraft to explore the Earth from orbit and on the surface since the 1960s, with the amazing Curiosity Rover landing in 2012. Every month since then, these probes have assisted them in learning fascinating new knowledge, and it is exciting to think about what they will learn next.
