Posted by: @wei-nihaoit's very hard to create wide spread life on Mars because it lacks a magnetic field to shield radiation. for a human colony you need keep up an artificial magnetic field.
Also, Humans will age faster on Mars which could be a turn-off for future human colonization.

Terraforming Mars completely will take a few centuries.
NASA has plans terraforming small areas instead and creating a Bio-Dome on it for the astronauts to live inside where they could remove their space-suit and breathe artificial air. They'll send robots first to construct the Bio-Dome and other infrastructures and this process will take less than a century and by then people could finally travel to Mars and live there without wearing a space-suit, a helmet and a breathing apparatus. A Bio-Dome allows them to move freely around compared to a spacecraft.
They'll probably send the astronauts the same way they sent satellites to planet Mars by using gravity and some fuel energy. It takes around 6 months for the spacecraft to arrive.
The only purpose of colonizing Mars that it's much easier to harvest the sun's energy and it's easier to build Nuclear energy on Mars that can be transferred back to earth.
If Earth is overpopulated in the year 2150, it would be a great alternative to preserve the existence of our species.
Planet Mars receives less sunlight than Earth since it's further away to the sun compared to Earth. Mars temperature throughout the year is extremely cold and windy. Since Mars has more volatile winds than Earth on average, astronauts could use it to supply a lot of energy. As mentioned by you, they could use nuclear energy however I'm not sure why would they need to transfer them back to Earth.
I also agree that peopling Mars would help alleviate the problem of overpopulation on planet Earth.
Does Mars receive less sunlight than Earth?
Mars is over 50 percent farther from the sun than Earth, so it receives less than half as much sunlight. This, plus the thin atmosphere, makes Mars pretty cold. It can get as warm as 80° Fahrenheit, but usually it is much colder, as cold as –200° Fahrenheit!
How much sunlight does Mars get compared to Earth?
The maximum solar irradiance on Mars is about 590 W/m2 compared to about 1000 W/m2 at the Earth's surface. The Sun's intensity on a horizontal patch of the Earth's surface of 590W/m2 occurs when the Sun is a mere 36 degrees above the horizon.
Energy harvesting is possible on Mars - Fully Charged - Archives - TI E2E support forums
Fortunately, the crazy weather on Mars is ideal for harvesting lots of energy. Wind is a significant weather pattern on Mars and can provide an abundant supply of energy. The extreme temperature gradients can also be a plentiful source of power for thermoelectric harvesting.
What would be the best energy source on Mars?
Nuclear energy is ideal for the initial missions, as it provides a reliable, powerful, long-lasting source of energy. Furthermore, the waste heat from the reactor can be used to drive ISRU reactions. Sep 16, 2020
