Did you know that NASA plans to send humans to Mars in the 2030s?

Earth’s inhospitable planetary neighbour, Mars, is best known for its dusty, red landscape. What do we really know about our neighboring planet? The surface of Mars has mountains, valleys, lowlands shaped by lava flows and large craters — all formed by the impact of meteorites. It has ice on the north and south poles, four seasons and a similar day and night cycle. Just like Earth, Mars orbits the sun and is made of rock and metal. In stark contrast, the atmosphere surrounding Mars is thin and hostile to life. Approximately 95% of its atmosphere is made of carbon dioxide and very little oxygen, which makes it toxic to humans. Radiation levels from the sun are high and there are extreme temperature changes due to Mars’s limited ability to hold heat. According to the National Aeronautics and Space Administration known as NASA, scientists believe that the climate on Mars 3.5 billion years ago may have been warm and wet, similar to Earth’s early climate. What caused this change? In recent years, scientists have been trying to understand how Mars lost its original atmosphere.
