When we land on Mars, we can expect numerous challenges and discoveries. Some key aspects we might encounter on Mars include:
Living Conditions: Mars has an extremely thin atmosphere, primarily composed of carbon dioxide. Temperatures are very cold, and there are no liquid water sources on the surface, making survival for human life challenging.
Research and Exploration: During a manned Mars mission, astronauts could conduct scientific investigations to learn more about Mars' history, geological composition, and possible traces of past life.
Colonization: In the long term, the idea of establishing a Mars colony could be considered. However, this would require significant technological advances and logistical challenges to establish a self-sustaining community on Mars.
As for the question of whether Mars was once inhabited, there is currently no evidence of past or present life on Mars. The scientific community, however, is interested in searching for traces of microorganisms or other indications of biological processes in the past. Missions like the Mars Rover and future expeditions may contribute to answering these questions.
