Model Suggests Spewing Metal Nanorods into Mars’ Atmosphere could Warm the Planet by 30K

Posted by in categories: engineering, environmental, nanotechnology, space

A small team of engineers and geophysicists from Northwestern University, the University of Chicago, and the University of Central Florida has found, via modeling, that creating millions of metal nanorods from material on the Martian surface and then blasting them into the atmosphere would be a more efficient way to heat the planet than generating greenhouse gases. Their paper is published in the journal Science Advances.

Science fiction writers have for many years envisioned a future when Mars is made habitable through terraforming techniques, allowing humans to survive without the need for special buildings and spacesuits. Recently, scientists have begun looking at the possibility, though most project ideas are far less ambitious.

Instead of completely transforming the planet, many are looking at simply warming it up a bit to make it more habitable. Most such ideas have centered on releasing greenhouse gases into the atmosphere to capture more heat from the sun. Unfortunately, there are few ingredients on the Martian surface that could be used to create and release such gases.

From Today To The Year 3000: Let’s Dive Into The Future!

Posted by in categories: biotech/medical, climatology, Elon Musk, environmental, life extension, robotics/AI, supercomputing, transhumanism, virtual reality

What does the future hold? What will become of this planet and its inhabitants in the centuries to come?
We are living in a historical period that sometimes feels like the prelude to something truly remarkable or terribly dire about to unfold.
This captivating video seeks to decipher the signs and attempt to construct plausible scenarios from the nearly nothing we hold in our hands today.
As always, it will be scientific discoveries leading the dance of change, while philosophers, writers, politicians, and all the others will have the seemingly trivial task of containing, describing, and guiding.
Before embarking on our journey through time, let me state the obvious: No one knows the future!
Numerous micro and macro factors could alter this trajectory—world wars, pandemics, unimaginable social shifts, or climate disasters.
Nevertheless, we’re setting off. And we’re doing so by discussing the remaining decades of the century we’re experiencing right now.

Can we make Mars Earth-like through terraforming?

Posted by in categories: engineering, environmental, space

🎵🎶…Mars ain’t the kind of place to raise your kids…🎵🎶 Even then, since Mars has 38% of Earth’s 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.

Huge Lake on Mars // Fate of Milkdromeda // Hope for VIPER Rover

Vast amounts of water found on Mars, but there’s 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.

Lunar Biorepository: Preserving Earth’s Precious Biodiversity

Posted by in categories: biological, engineering, environmental, existential risks, sustainability

Could we store samples of Earth’s 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 Moon’s 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 Earth’s biodiversity from extinction while improving future space exploration and possible terraforming of other worlds.

“Initially, 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,” said Dr. Mary Hagedorn, who is a research cryobiologist at the Smithsonian National Zoo and Conservation Biology Institute and lead author of the study. “We 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.”

The reason lunar PSRs are of interest for this proposal is due to several craters being completely devoid of sunlight from the Moon’s small axial tilt (6.7 degrees versus Earth’s 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.

This Plant Is So Extreme Scientists Think It Could Thrive on Mars

Posted by in categories: engineering, environmental, space

Mosses are among Earth’s 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 – we don’t have a great track record with this on our own planet.

But if we decide it’s 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.

Detecting Alien Terraforming with Artificial Greenhouse Gases

Posted by in categories: alien life, climatology, engineering, environmental

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.

“For us, these gases are bad because we don’t want to increase warming” said Dr. Edward Schwieterman, who is an Assistant Professor of Astrobiology at the University of California Riverside and lead author of the study. “But they’d 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.”

Exporting Earth

Posted by in categories: biotech/medical, engineering, environmental, genetics, media & arts, space travel

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.

Seeding the Stars

Posted by in categories: engineering, environmental, media & arts, space

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.
