Last March, ExoMars (Exobiology on Mars) was sent to gather information on Mars and was able to take and send photos to Earth at a speed of 2Mbit/s. The mission is made up of two sub-missions.
The first part is the Schiaparelli lander, which separated from ExoMars on October 16, Sunday. Schiaparelli was announced as a landing demonstrator that will unleash a suite of sensors to measure meteorological phenomenon on the surface. The Trace Gas Orbiter (TGO) which will remain above the Martian surface will plot out sources of methane gas (a clear sign of organic life). But before it gets there, it's gonna do something really cool.
Getting to Know the ExoMars
In 2020, ExoMars' second part will launch and in 2021, will deliver a rover to the Martian surface. The rover will carry an exobiology laboratory suite onboard to help its hunt for biosignatures created by small Martian microbes.
The interest of scientists of Earth on Mars is because of its many things that might make it amenable to us: It contains some water, The temperature does not exceed or lack for what's necessary for humanity to survive, and it doesn't have battery acid for an atmosphere.
These attributes excited the interest of science fiction writers, but there is some proof that Mars may be a place where life can flourish, whether it's indigenous or foreign. With all of these aforementioned facts, the probability of Mars being capable of supporting life in the future is just very high.
This is the main reason why humanity is looking at Mars for a possible future planetary colonization. Hopefully, if all goes well and the trend of Martian space exploration continues, the odds of man colonizing the red planet will surely increase. Exploration is indeed in mankind's nature.
