Trump Advocates for Martian Settlement - Prospects Explored
Is Humankind's Next Frontier Mars?
In 1964, NASA's uncrewed Mariner 4 spacecraft successfully made its first flight past Mars. Fast forward to July 1976, when Viking 1 landed on the Martian surface, marking the first successful manned landing on the red planet. Since then, numerous exploration missions have been executed, with some successes and failures.
Although no crewed mission has been attempted, the idea of colonizing Mars has fascinated influential figures like the late Stephen Hawking and Elon Musk, SpaceX's visionary CEO. While some experts, including renowned astrophysicists like Martin Rees, believe that manned missions to Mars are achievable, living on Mars might pose a much greater challenge.
The Red Planet: A Terrestrial Analog in Extremis
Mars, the most Earth-like planet in our solar system, is covered primarily in rock and dust. However, it lacks any significant bodies of water on its surface, with astronomically cold temperatures and minimal moisture. Despite the inhospitable conditions, Mars was believed to have been more water-rich in the past.
With a rotational period of approximately 24 hours and 37 minutes, Mars shares a similar day-night cycle with Earth. The red planet also has a tilted axis similar to Earth's, giving it four distinct seasons. However, Mars's extreme cold averages -65°C, making survival a daunting challenge.
Struggling for Breath and Staying Grounded
Mars's gravitational pull is around 38% of Earth's, allowing humans to walk without floating away. Yet, breathing on Mars is virtually impossible due to its painfully thin atmosphere, which is 96% carbon dioxide and only 0.13% oxygen.
To survive, humans on Mars would require spacesuits and oxygen tanks, and they would need to live within highly pressurized habitats, as the Martian atmosphere's pressure is roughly 1% of Earth's.
The Great Distance: Challenges and Opportunities
The distance between Mars and Earth is not constant, with the planets' elliptical orbits causing the separation to vary. Mars reached its closest point to Earth in 2003, being only 34.8 million miles away. However, its farthest distance is about 250 million miles.
A propitious alignment of the planets' orbits presents an opportunity for exploration missions every 26 months. It took the Viking 1 spacecraft ten months to travel to Mars, while the Perseverance rover made the trip in less than seven months. NASA aims to bring the journey duration down to nine months, while SpaceX aspires to travel there in just six months.
Potential advancements in propulsion systems might enable future spacecraft to reach near the speed of light, reducing journey times to as little as three days.
Dreams Taking Shape or Just Wishful Thinking?
In 2020, US President Donald Trump declared his intention to lead humanity into space and plant the American flag on Mars. Although such an achievement seemed unlikely within four years, it is possible within the next two to three decades, according to both NASA and SpaceX.
NASA aims to place astronauts on Mars's surface in the early 2030s, with efforts underway to address the challenges of oxygen supply, food, water, power, communication, and shelter. Concurrently, SpaceX remains committed to undertaking uncrewed test flights to Mars by the end of 2026 and crewed missions soon after.
Can Humans Thrive on Mars?
Although liquid water may not be found on the Martian surface, there is evidence of large ice glaciers and vast amounts of water beneath the planet's surface. This raises the possibility of growing plants for food and materials, producing fuel, and utilizing the water for rocket propellants.
Moreover, Mars's water could potentially yield valuable resources, as it is five times richer in deuterium, a fuel for nuclear fusion reactors.
Terraforming Mars: A Moonshot or a New Reality?
The concept of terraforming—transforming a planet's environment to make it more hospitable to humans—remains contentious. While technological advances may one day make it feasible, widespread agreement on its moral justifiability is elusive. In Mars's case, settling humans on the planet would necessitate addressing issues such as global dust storms, the lack of a magnetic field to shield against solar radiation, and the toxic perchlorates found in Martian "soil."
The emerging field of synthetic biology might offer a solution, with the potential to detoxify Mars and enable food production. The pursuit of terraforming Mars could lead to the creation of a new species or even inorganic intelligences, as humans adapt to the alien environment.
Adapting to Survive on Mars
To survive on Mars, astronauts might need to adapt genetically or embrace new technologies to cope with the harsh conditions. Inevitably, these adaptations could lead to the first divergence into a new species or even the development of non-biological brains.
