MARS IN THE FOURTH POSITION

Today, I want to tell you about "MARS IN THE FOURTH POSITION".

NASA has several Mars missions planned for the next decade. Mars is the fourth planet from the Sun. It is a very active planet like the Earth. It has evidence of volcanoes, plate tectonics, and liquid water (as opposed to ice) on the planet. It even has polar ice caps like the Earth, with water in the north and solid carbon dioxide in the south. With all of these similarities, Mars is still nothing like Earth. It only has 40% of our gravity because the mass of the planet is so much smaller. Also, its atmosphere is made up of carbon dioxide and has less than 1% of the atmospheric pressure of Earth.
