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.

A message to all artists out there! By creating art, you are an artist. There’s no milestone you have to hit or skill level you need to be at. You can draw once every few years or finish writing a chapter a week. You can crochet goods only for your family or sell your music to hundreds. Nothing qualifies or disqualifies you, so you are most definitely an artist. 🎨✨

More inspirational chubby penguins in my book Loading Penguin Hugs! 💛

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.

Here’s a tutorial on how I color/shade

Thought I’d share out my lil’ tutorial using the basic brushes and blends in CSP for quickly colouring hair!

Only make super thin strands and hundreds of them if you don’t mind spending the next 20 years colouring them! ❤️

Pidge!!! some of them are aviable as sktickers on redbubble!!

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

((Hey thanks for the ask! I use paint too sai and these are just a few brush settings that I use. I use a lot of brushes but these are probably most common! Hope this helped in some way, if you have other questions about how I ‘draw’ feel free to ask! ))

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.
