Sugar-Producing Bacteria To Be Tested in Space as Food Source for Astronauts. The Key to Colonizing Mars Could Be These Tiny Green Microbes.


Let's Nuke Mars! Astromike23 comments on How would nuking Mars' poles create greenhouse gases? Terraforming Mars by nudging asteroids into a collision course, forty such impacts would give Mars a temperate climate, and enough water would have been melted to cover a quarter of the planet with a layer of water 1m deep. : space. Theconversation. Gravity is a constant for all organisms on Earth.


It acts on every aspect of our physiology, behavior and development – no matter what you are, you evolved in an environment where gravity roots us firmly to the ground. Mars One Is Still Completely Full of Shit. DARPA: We Are Engineering the Organisms That Will Terraform Mars. Terraformed Mars, artist's conception.

DARPA: We Are Engineering the Organisms That Will Terraform Mars

Image: Daein Ballard/Wikimedia Commons It’s no secret that the Defense Advanced Research Projects Agency is investing heavily in genetic engineering and synthetic biology. Whether that excites or terrifies you depends on how you feel about the military engineering totally new life forms. If you’re in the excitement camp, however, here’s a nugget for you: DARPA believes that it's on the way to creating organisms capable of terraforming Mars into a planet that looks more like Earth. The goal of terraforming Mars would be to warm up and potentially thicken its atmosphere by growing green, photosynthesizing plants, bacteria, and algae on the barren Martian surface. NASA Wants Your Help Figuring Out How to Build Space Habitats. NASA Will Make Oxygen From CO2 On the Surface of Mars. How Asteroid Mining Could Pay for Our First Space Colony. A Warm Seafloor On Enceladus Makes It A Prime Candidate For Life.

Saturn's Moon Enceladus Has a Warm Ocean, Could Have Life. Move over, Europa.

Saturn's Moon Enceladus Has a Warm Ocean, Could Have Life

It looks as though the most life-friendly habitat ever discovered outside of Earth is Enceladus—Saturn's sixth-largest moon. Astrophysicists working with NASA's Saturn sweeping Cassini spacecraft have just announced that Enceladus has a warm ocean at its southern pole with ongoing hydrothermal activity—the first ever discovered outside of Earth. This new research, published in the journal Nature, builds upon last year's discovery of the moon's 6-mile-deep ocean, which is also believed to contain many of the chemicals commonly associated with life. Terraforming the Solar System. The Surprisingly Strong Case for Colonizing Venus. Why worry about building a colony on Mars when instead you could float one high above the surface of Venus?

The Surprisingly Strong Case for Colonizing Venus

Science fiction writer Charles Stross recently revived the idea of building a Venutian colony when he suggested, cheekily, that billionaires ought to be compelled to donate to massive humanity-improving projects. He suggested two: a Manhattan Project-like focus on developing commercial nuclear fusion, or the construction of a floating city on Venus. The second planet from the Sun might seem like a nasty place to build a home, with a surface temperature hot enough to melt lead and an atmosphere so dense it would feel like being submerged beneath 3000 feet of water. But the air on Venus thins out as you rise above the surface and cools considerably; about 30 miles up you hit the sweet spot for human habitation: Mediterranean temperatures and sea-level barometric pressure.

Space Station research shows that hardy little space travelers could colonize Mars

These days, scientists are more concerned about invaders to Mars, in the form of micro-organisms from Earth. Organisms hitching a ride on a spacecraft have the potential to contaminate other celestial bodies, making it difficult for scientists to determine whether a life form existed on another planet or was introduced there by explorers. Currently, spacecraft landing on Mars or other planets where life might exist must meet requirements for a maximum allowable level of microbial life, or bioburden.

The One Scientific Field Most Likely to Get Humanity Into Space. '2312', by KS Robinson, is the first, best example of the ways in which speculative fiction serves to imagine first, a solar ecology - replete with diverse microecologies - through terraforming.

The One Scientific Field Most Likely to Get Humanity Into Space

In fact, Terraforming and remedial Terraforming might be the most appropriate name for your speculative, synergistic, scientific field. In my view. The Complications of Sex in Space. Credit: Misha Gravenor Among the most basic needs – not to mention, desires – that human beings must contend with is the very complicated task of reproduction.

The Complications of Sex in Space

The complexities and pleasures of this instinctual act are as beautiful as they are important. It, like most “normal” tasks, becomes much more difficult once you fly beyond the thin band that separates Earth from the heavens. So, what’s the big deal, you may ask? Sex in Space: First, both NASA and the Russian Federal Space Agency officially claim that the act of sexual penetration has never occurred in space, but (as always) there are rumors and innuendos that indicate otherwise. Behold the incredible places where we'll build cities in space. Another thought provoking article at io9.

Behold the incredible places where we'll build cities in space

Europa is a must-go-now destination. Forget about the very entertaining film of the same name, I want to see a global effort to send a submersible probe, outfitted with a drill to find passage beneath it's icy surface, and I don't want to wait twenty years for this to happen. The exploration, militarization and colonization of our solar systems jurisdiction is "crucial" to the survival of our species.

Data from Skylab and Mir showed conclusively that bone loss and muscle atrophy occurs in zero-G environments. The worst news: on average, loss is 1-2% per month, but some individuals lost 20% over a six month period in the lower extremities! (Source: Once the travelers get to mars and walk around, their bone loss rate should cease or approach zero. The current idea is that bones that are subjected to mechanical load maintain their mass.
