Like Earth, Mars has clouds in its atmosphere, seasons,and volcanoes.However, conditions on Mars are very different from those on our own planet. Between day and night, temperatures vary by 100 degrees Celsius.Dust storms with winds reaching 480 kilometers per hour occur at certain times of year and form giant tornadoes. Mars's atmosphere is thinner than Earth's, and it toxic to humans.Future missions to Mars will answer many questions about the planet and will make new discoveries. New technologies will enable scientists to explore Mars in new ways. The future will bring better pictures from more areas, and they will even return soil and rock samples from Mars for studies in laboratories here on Earth.recently, the robots spirit and Opportunity transmitted over 50,000 images of the planet. Opportunity examined a crater, which gave scientists evidence that the area was once covered in water.
