The article discusses the challenges of colonizing Mars, highlighting the extreme conditions presented by the planet's atmosphere and environment. Despite being a prime candidate for exploration, Mars is inhospitable due to its thin atmosphere and lack of liquid water. NASA and proponents like Elon Musk are advocating for human presence on Mars, potentially through enclosed habitats. Long-term visions involve terraforming, a proposal that involves changing its atmospheric pressure to support life. Scientists are considering various methods, including bombarding Mars with asteroids, to initiate this massive transformation.
Scientists accept that any proposal for terraforming Mars is decades away, although calculations are already underway to assess how this titanic process might work.
On Earth, atmospheric pressure is due to the total mass of gases contained in its dense atmosphere. Here, at sea level, the pressure is equivalent to 101,325 pascals; on Mars it barely reaches 600 pascals.
