Could We Terraform Mars?
PBS Space Time・15 minutes read
Humanity aims to terraform Mars to make it habitable for settlers by creating an Earth-like atmosphere through various methods, including releasing trapped water and atmosphere from Mars' crust. The vision of colonizing Mars involves city-sized bubbles covering cities to create lush oases resembling Earth, with efforts like LEGO City Space inspiring future space explorers.
Insights
- Terraforming Mars involves releasing trapped water and atmosphere from Mars' crust to create a protective atmosphere against cosmic rays and radiation, aiming to make the planet habitable for settlers.
- Paraterraforming with worldhouses, airtight bubbles covering cities on Mars, could offer a more feasible solution than full-scale terraforming, potentially leading to city-sized bubbles with lush oases resembling Earth, marking a significant step towards humanity's dream of terraforming space.

Recent questions
How can Mars be made habitable?
By releasing trapped water and atmosphere from Mars' crust and ice caps to kickstart a greenhouse effect, creating an atmosphere similar to Earth's to protect against cosmic rays and ultraviolet radiation.
What challenges does Mars colonization face?
Mars faces challenges due to its weak gravitational field and lack of a global magnetic field, leading to the loss of its atmosphere over billions of years. Current technology struggles to replenish Mars' atmosphere with accessible carbon dioxide sources like polar ice caps or surface dust.
What is paraterraforming?
Paraterraforming involves using worldhouses, airtight bubbles covering cities, as a more feasible solution than full-scale terraforming to create Earth-like conditions on Mars. These city-sized bubbles could contain lush oases resembling Earth on the barren Martian landscape.
What technologies are needed for Mars colonization?
Mars colonization requires a massive effort involving solar cells, fusion power plants, and robotic miners to achieve Earth-like conditions on the planet. These technologies are essential for creating a breathable atmosphere and sustaining life on Mars.
How does LEGO City Space contribute to space exploration?
LEGO City Space, inspired by real aerospace technology, aims to inspire future space explorers to contribute to the journey to Mars. By celebrating 50 years since the moon landing, LEGO City Space encourages innovation and interest in space exploration for the next generation.

"Transforming Mars: Creating Earth-like Conditions"
- Humanity envisions a future of space travel, terraforming planets, and creating Earth-like orbs in the galaxy.
- The first step towards this vision is terraforming Mars to make it habitable for settlers.
- Mars currently lacks a suitable atmosphere, with an atmospheric pressure only 0.6% of Earth's, making it deadly for humans.
- Terraforming Mars involves creating an atmosphere similar to Earth's to protect against cosmic rays and ultraviolet radiation.
- Scientists aim to release the trapped water and atmosphere from Mars' crust and ice caps to kickstart a greenhouse effect.
- However, Mars' weak gravitational field and lack of a global magnetic field have led to the loss of its atmosphere over billions of years.
- Current technology cannot replenish Mars' atmosphere with accessible carbon dioxide sources like polar ice caps or surface dust.
- Deep carbonate minerals beneath Mars' surface may hold enough CO2 to potentially create a breathable atmosphere.
- To achieve Earth-like conditions on Mars, a massive effort involving solar cells, fusion power plants, and robotic miners is necessary.
- Alternatively, paraterraforming with worldhouses, airtight bubbles covering cities, could provide a more feasible solution than full-scale terraforming.
