I Just Want My Sufferings To End.

I’d be more terrified by the absence of aliens in the universe rather than the presence of them.

Hostile and Closed Environments, Hazards at Close Quarters

A human journey to Mars, at first glance, offers an inexhaustible amount of complexities. To bring a mission to the Red Planet from fiction to fact, NASA’s Human Research Program has organized some of the hazards astronauts will encounter on a continual basis into five classifications.

A spacecraft is not only a home, it’s also a machine. NASA understands that the ecosystem inside a vehicle plays a big role in everyday astronaut life.

Important habitability factors include temperature, pressure, lighting, noise, and quantity of space. It’s essential that astronauts are getting the requisite food, sleep and exercise needed to stay healthy and happy. The space environment introduces challenges not faced on Earth.

Technology, as often is the case with out-of-this-world exploration, comes to the rescue! Technology plays a big role in creating a habitable home in a harsh environment and monitoring some of the environmental conditions.

Astronauts are also asked to provide feedback about their living environment, including physical impressions and sensations so that the evolution of spacecraft can continue addressing the needs of humans in space.

Exploration to the Moon and Mars will expose astronauts to five known hazards of spaceflight, including hostile and closed environments, like the closed environment of the vehicle itself. To learn more, and find out what NASA’s Human Research Program is doing to protect humans in space, check out the “Hazards of Human Spaceflight" website. Or, check out this week’s episode of “Houston We Have a Podcast,” in which host Gary Jordan further dives into the threat of hostile and closed environments with Brian Crucian, NASA immunologist at the Johnson Space Center.

big daddy fan art, started playing through BioShock again 

Apologies in advance for any spelling errors, I’ll fix stuff in the morning…too tired now…

oh hey it’s a tutorial on glowing stuff I guess…I already made one 2 years ago but I don’t make things glow like that any more :|

…also when I’m manually doing colours I pick things like this as if I was shading.

there’s a lot more I could put in as well, but it really varies on the picture how I do the glow…it is usually just fiddling around with styles and colours though.

How does a microgravity garden grow when there’s no up or down? An advanced chamber, about the size of a mini-fridge, is giving us a clearer perspective of plant growth habits. Without gravity and the addition of a wide variety of light and humidity settings, the plants cultivated on the International Space Station provide a world of opportunity to study space-based agricultural cycles.
