We Should Deliberately Contaminate Mars With Our Microbes, Controversial Study Argues
A research team is proposing a major philosophical shift in our thinking about the spread of Earthly microbes in space and on Mars in particular. Believing interplanetary contamination to be “inevitable,” the team argues that future Martian colonists should use microorganisms to reshape the Red Planet—a proposition deemed grossly premature by some experts. In a … Continued

Scientists Develop Material to Create Habitable Areas on Mars
Mars’ surface, as far as we can tell, is not habitable to humans—it’s far too cold. But eventually, humanity would like to put an outpost on the planet. That will require warming things up a bit, but how? Scientists now propose using an insulating material called silica aerogel to make parts of the Martian surface … Continued

Maybe We Don’t Have to Nuke Mars (So Much) After All
Terraforming Mars could be our only option once we screw this planet up beyond repair, but how exactly are we going to do it? One popular scheme involves releasing truckloads of nuclear warheads over the poles, unlocking billions of tons of frozen carbon dioxide and triggering a runaway greenhouse. But if sending your kids to … Continued

The Key to Colonizing Mars Could Be These Tiny Green Microbes
Long ago, a clan of hardy microbes called cyanobacteria helped terraform the lifeless Earth into a vibrant biosphere. Today, the very same critters could be the key to colonizing Mars. Plants are going to have a tough time on the Red Planet’s hostile surface, but cyanobacteria have coped with extreme environments for eons. A paper … Continued

Why So Many Countries Are Building Airstrips on These Remote Islands
The Spratly islands are not a natural spot for a layover. They are isolated—tiny, shallow islands spread out over a huge chunk of the South China Sea. So why are so many nations rushing to construct airline runways and other infrastructure there? On a map, the islands look like someone flicked a paintbrush at Earth … Continued

Should We Terraform a New Planet Or Fix Our Own?
Before we talk about terraforming another planet like Mars, we have to talk about Earth—and whether we should be spending our resources trying to save it, or moving on to another pale blue dot. It’s a grim debate that some scientists say it’s time to have. Terraform This We’ve been imagining how to create a … Continued

China Says Its Artificial Island Project Will Be Done In a Few Days
It’s been more than a year since we first started following China’s project to build artificial islands in contested areas of the South China Sea, setting off what could properly be called a diplomatic shit storm. Today, China reassured the world that it’s almost done, alright? Image: The Center for Strategic and International Studies For … Continued

Geologist Races To Learn Mars’ Secrets Before The Planet Is Terraformed
In the short film Red Witch, an aging geologist hopes to learn Mars’ history before terraforming alters the planet’s landscape forever. But she finds that the people she’s working with aren’t interested in hearing Mars’ story — they just want to prepare the planet for colonization. Aron Bothman made Red Witch as his fourth year … Continued

China Is Turning a Remote Reef Into an Artificial Island With a Runway
A remote archipelago in the South China Sea has come under an extraordinary amount of scrutiny lately. Here, China is building up small reefs and atolls into whole artificial islands—all in hotly disputed territory. In the clearest sign yet of its military intentions, one of those islands now has an airstrip. Satellite images taken on … Continued

Incredible Satellite Images Show China Building Artificial Archipelago
It seems strange that a remote patch of water would become the focus of international controversy and millions of dollars worth of infrastructure. But that’s exactly what’s happening in the South China Sea right now. At a news conference today, China’s Foreign Ministry spokesperson spoke about the country’s project to reclaim seven reefs, turning them … Continued

The Technology That Will Build Our Future May Be Found In Mushrooms
The key to the human race’s future may be right beneath our feet. It sounds bizarre, but fungi better known as mushrooms can help solve many of society’s greatest challenges, from cleaning up the environment and living more sustainability to colonizing other planets. Threaded into nearly every square inch of the ground are tiny, biological … Continued

Kim Stanley Robinson Wanted To Go Hiking On Mars, So He Wrote Red Mars
Kim Stanley Robinson’s Mars trilogy is one of the most important books about terraforming (and interplanetary colonization) of the past 20 years. And Robinson spent 10 years working on it, learning a lot about the subject as he went. But it all started becuase he fantasized about going backpacking on Mars. Over in Kirkus Reviews, … Continued

How Will We Decide Which Planets To Terraform?
Transforming another planet, moon, or other celestial body into a world fit for human habitation may be a key component of our post-Earth survival. But how will we determine which worlds should be terraformed and which should be left alone? Terraforming is just one possibility for human colonization of space. In his seminal work Terraforming: … Continued

Martian Paradise: Mars Had Oxygen-Rich Atmosphere, 4 Billion Years Ago
Rocks collected by NASA’s Spirit rover on Mars show evidence of an oxygen-rich atmosphere some 3.7 billion years ago. This is a very strong indicator of life, with scientists describing the ancient Martian environment as “wet, warm and rusty.”

Watch a day in the life of a terraformed Mars
No, this isn’t Earth or an artistic rendering of some far away exoplanet. It’s Mars — but a hypothetical version of the Red Planet after it’s undergone a rather radical facelift.

New Images Show a “Living” Mars
Over the years, scientists have found evidence revealing that an ocean may have covered parts of the Red Planet billions of years ago. Others suggest that a future terraformed Mars could be lush with oceans and vegetation. In either scenario, what would Mars look like as a planet alive with water and life? By combining … Continued
