đ”đ¶âŠMars ainât the kind of place to raise your kidsâŠđ”đ¶ Even then, since Mars has 38% of Earthâs gravity, it can only retain an atmosphere of about 0.38 bar.
These are some of the most compelling ideas on how to terraform Mars into a habitable, Earth-like world for future explorers.
Vast amounts of water found on Mars, but thereâs a catch, Milky Way and Andromeda might not merge after all, a planet found before it gets destroyed, and an easier way to terraform Mars.

Could we store samples of Earthâs endangered biodiversity on the Moon for long-term preservation? This is what a recent study published in BioScience hopes to address as a team of researchers led by the Smithsonian Institution proposes how the Moonâs permanently shadowed regions (PSRs) located at the lunar north and south poles could be ideal locations for establishing a lunar biorepository where endangered species can be cryopreserved. This study holds the potential to safeguard Earthâs biodiversity from extinction while improving future space exploration and possible terraforming of other worlds.
âInitially, a lunar biorepository would target the most at-risk species on Earth today, but our ultimate goal would be to cryopreserve most species on Earth,â said Dr. Mary Hagedorn, who is a research cryobiologist at the Smithsonian National Zoo and Conservation Biology Institute and lead author of the study. âWe hope that by sharing our vision, our group can find additional partners to expand the conversation, discuss threats and opportunities and conduct the necessary research and testing to make this biorepository a reality.â
The reason lunar PSRs are of interest for this proposal is due to several craters being completely devoid of sunlight from the Moonâs small axial tilt (6.7 degrees versus Earthâs 23.5 degrees). The team postulates this presents ample opportunity for storing several groups, including pollinators, threatened and endangered animals, culturally important species, and primary producers, just to name a few.
Mosses are among Earthâs great terraformers, turning barren rock into fertile soils, and now a team of scientists is proposing these non-vascular plants could do the same on Mars.
Whether we should introduce life from Earth onto our red neighbor is another question â we donât have a great track record with this on our own planet.
But if we decide itâs worth messing with soil on Mars to create a second home for us Earthlings, ecologist Xiaoshuang Li and colleagues at the Chinese Academy of Sciences have a candidate that they think should do just the trick.
This plant that could survive the harsh conditions on Mars, which could help future human missions to explore and terraform the red planet.
Could we identify an alien terraformed planet through the detection of greenhouse gases? This is what a recent study published in The Astrophysical Journal hopes to address as a team of international researchers investigated whether artificial greenhouse gases could be detected from an exoplanet whose alien inhabitants could be attempting to terraform that world, either from trying to control its climate or terraforming an uninhabitable planet into a habitable one. This study holds the potential to help scientists better understand the criteria and methods for identifying an extraterrestrial civilization, especially with the number of confirmed exoplanets increasing almost weekly.
âFor us, these gases are bad because we donât want to increase warmingâ said Dr. Edward Schwieterman, who is an Assistant Professor of Astrobiology at the University of California Riverside and lead author of the study. âBut theyâd be good for a civilization that perhaps wanted to forestall an impending ice age or terraform an otherwise-uninhabitable planet in their system, as humans have proposed for Mars.â
In order to terraform new planets, we will need to be able transport entire ecologies & ecosystems through interstellar space in the future. Today we will examine how we could build and maintain such environments inside vast arks, generations ships able to colonize our galaxy, and the challenges these starships will face maintaining not just stores of DNA and genetic material but living organisms which depend heavily on other members of their species and other species to survive and thrive, not least of which is human ourselves.

The galaxy is a vast place with billions of potential new worlds for humanity to colonize, but interstellar space is so enormous that reaching even the nearest stars and planets by spaceship would take decades at best, and maybe many centuries. Even on arrival terraforming those barren planets would take just as long.
Two options for overcoming the immensity of space and time are the Seed Ship and the Data Ship, automated vessels able to colonize the worlds for us. We will examine those today, their advantages, limitations, and misconceptions, and variations of them we might use to seed the stars.

Disclaimer:
This is a sci-fi documentary, looking at what it takes to build an underground city on Mars. The choice to go underground is for protection, from the growing storm radiation that rains down on the surface every day. And to further advance the Mars colonization efforts.
Where will the materials to build the city come from? How will the crater be covered to protect the inhabitants? And what will it feel like to live in this city, that is in a hole in the ground?
It is a dream of building an advanced Mars colony, and showing the science and future space technology needed to make it happen.
Personal inspiration in creating this video comes from: The Expanse TV show and books, and The Martian.
Other topics in the video include: the plan and different phases of construction, the robots building the city, structures that are on the surface versus below the surface, pressurizing a habitat on Mars, the soil and how to turn it in Martian concrete, the art of terraforming, and the different materials that can be extracted from the planet. And the future plans of the Mars colony, from building upwards to venturing to the asteroid belt and Jupiterâs 95 moons.
