The red planet (Mars) appears to rotate clockwise in the night sky. Mars is the planet in the solar system that has the most similar environment to Earth. Some scientists expect that the discovery of traces of water and ice indicates the possibility of life. Elon Musk established the American space corporations SpaceX with the goal of colonizing Mars. With an average temperature of minus 63 degrees, terraforming is necessary for humans to reside continuously on Mars. The photo shows Mars taken at intervals of 5 to 9 days from September of last year to mid this month, combined to illustrate its position at each time.
