NASA detects atomic oxygen on Mars
According to scientists, during the year the amount of oxygen in the Martian atmosphere changes significantly: in spring it increases sharply, and in winter it falls. This phenomenon can be explained only by the fact that there are some kinds of life forms on the planet. What is more, perchlorate, a special substance, can be found in abundance in the Martian soil. When it decomposes, O2 is released. Microorganisms cannot live on the surface of the planet; they hide in a depth of 1-2 m. Scientists plan to find them using deep drilling. For now, the soil of the Red Planet is drilled only by 35 cm, and it is very difficult to identify any forms of life there.
