On Mars for the first time in history have discovered traces of ozone and carbon dioxide.
New gas signatures on Mars noticed Space gas Orbiter ESA.
The planet had traces of ozone and carbon dioxide, which earlier never have found.
ESA experts say that new data on the Martian atmosphere will help to know whether the planet is methane. This gas is directly linked to geological LII biological activity on the planet.
Methane destroyed after about 400 years. Its detection on other planets are evidence of its relatively recent allocation.
