Mars is an interesting and mysterious planet. It is often referred to as the Red Planet. The Romans named Mars after the god of war. The rocks, soil, and sky all have a red hue on account of rust. Mars is the fourth planet from the sun at about 141 million miles (228 million kilometers) and the last terrestrial planet from the Sun. Mars follows closely behind Earth but is comparatively smaller, with about half the diameter of Earth (6,794-km) and about one-tenth of Earth s mass (6.419 x 1023 kg). Thus the force of gravity on Mars is about one-third of that on Earth. Mars is probably the planet we know the most about since it is so close to Earth, though what we know now is not even close to everything about the planet. Over the past several decades, humans have been interested about life on mars.
In 1877, Giovanni Schiaparelli, an Italian astronomer, was the first person to draw a map of Mars. His map showed a system of streaks or channels, which he called canali. In 1910, the U.S. astronomer Percival Lowell made observations of Mars and wrote a book. In his book, Lowell described Mars as a dying planet where the civilizations built an extensive network of canals to distribute water from the polar regions to the center of the planet. Mars was discovered by scientists in the 1600’s. Researchers descried a pale pink object that was only visible in the early morning just before dawn. The object moved closer to the stars, got brighter over the next year and rose earlier and earlier. Then it reversed direction. Mars was the third most brightest object in the night sky, it had an intense red color and could see all night long. After moving the opposite direction for about 70 days, it reversed direction again, and gradually got dimmer. It was only visible in the evening sky and set earlier and earlier. After another year it again was a pale pink object, this time only visible just after sunset. Shortly after that, it could not be visible at all. It
