The idea of migrating humans to Mars may be possible.
But it won’t be easy for establishing a permanent, sustainable outpost on the Red Planet.
What should scientists do to make this our civilization’s only chance of long-term continuity?
Few days ago, Japanese space agency JAXA announced (http://mmx-news.isas.jaxa.jp/?p=1016&lang=en) it has greenlit a sample return mission to the Martian moon Phobos called the Martian Moons Exploration mission (MMX). If it’s successful, it could result in the first vehicle in the history of space travel that’s made it to the Martian system and back home, here, to Earth.

colony on Mars. We are still struggling for sustainable colonies on Earth
As the only other planet in the solar system we are likely to be able to settle on, Mars looks like the best first step towards establishing an off-Earth foothold. But making Mars a sustainable destination will require a few advances beyond those needed for one-off trips.

"Significant progress has been made in space exploration, with various organizations like SpaceX, NASA, and others working towards sending humans to Mars. Advancements in propulsion systems, life support systems, and habitat construction will play a crucial role in making sustainable settlements a reality. Developing these technologies and ensuring their reliability will be a significant challenge.
Establishing a sustainable settlement on Mars requires the efficient use of the planet’s resources. This includes utilizing Martian water, regolith, and atmosphere to generate oxygen, water, and building materials. In-situ resource utilization (ISRU) technologies are being developed and tested to achieve this goal, but their effectiveness and scalability remain to be proven.
The long journey to Mars and the Martian environment pose various health risks to astronauts, such as radiation exposure, microgravity-induced bone loss, and mental health challenges. Addressing these issues through advanced medical countermeasures, habitat designs, and mission planning will be essential for the long-term well-being of Martian settlers.
For long-term sustainability, settlers will need to grow food on Mars. However, the harsh climate, lack of water, and low sunlight levels make traditional agriculture challenging. Research into alternative farming methods, such as hydroponics, aeroponics, and other controlled environment agriculture techniques, will be crucial for overcoming these challenges and providing settlers with a reliable food supply.
A sustainable settlement on Mars requires a reliable power source. Solar power, nuclear power, and other advanced energy generation technologies will need to be developed and implemented to meet the energy needs of a Martian settlement. Ensuring the safety, reliability, and efficiency of these energy systems will be a significant challenge.
The cost of sending humans to Mars and establishing a settlement is enormous. International collaboration and public-private partnerships will likely be necessary to share the financial burden and pool resources and expertise. Coordinating these efforts and maintaining long-term commitment from all stakeholders will be essential for the success of the mission."
