The possibility of life on Mars is a subject of significant interest to astrobiology due to its proximity and similarities to Earth. To date, no proof has been found of past or present life on Mars.
Scientists have been trying to collate evidences to figure out whether life has ever existed on this planet or is it inhabited with people presently or if there is any possibility of life on Mars in the future.
Cumulative evidence shows that during the ancient Noachian time period, the surface environment of Mars had liquid water and may have been habitable for microorganisms.
Scientists have been trying to conduct research on Mars by way of telescopes, spacecrafts and rovers that are helpful in collecting evidences about the condition and nature of this planet.
It is interesting and exciting to learn that life on this planet may be possible as its atmosphere is quite similar to Earth.
