Astronauts

Overview

Sailing beyond the horizon, astronauts take up residence among the stars to further research into space exploration and colonization. With limited resources, no running water, and under ongoing adaptation to microgravity, they spend most of their days conducting experiments and space station maintenance. Use these resources to learn more about the adventurers of our age.

  • Microgravity environments lead to muscle mass loss

    Muscles that assist with balance and resistance to gravitational forces go without their usual workload in the International Space Station. Visitors follow a rigorous fitness regimen with 15 hours of weekly exercise to minimize these losses.

  • How do astronauts battle loneliness and depression?

    You’re stranded hundreds of miles away from your friends and family, constantly surrounded by coworkers who also are your roommates, and you’re only allowed the shortest of walks outside. There’s also no takeout, and gravity has essentially broken up with you. You might need a little help adjusting mentally. That’s where space psychologists and psychiatrists step in, according to this article.

  • Who’s in space right now?

    Hundreds of people (and a few animals) have been to space since the first creatures flew past the Kármán line in 1947. There are a handful of astronauts aboard the International Space Station at any time, while others may be cresting space in...

  • What is space sickness?

    Mix motion sickness minus gravity with a host of other variables, and you’ve got a recipe for space adaptation syndrome. It can hit anyone, even astronauts who escaped the issue previously. This article details the history and science behind space sickness.

  • Has anyone had sex in space?

    Reproduction is a basic human function, and while we've spent decades in space, no research has been done into the process. With many discussing the possibility of human-occupied bases on the moon, Mars, and more, understanding how sex works outside...

  • See who is in space right now

    Over 600 people have been in space since the space race took off decades ago, with roughly 10 in space at any given time, typically operating the world's growing number of space stations. This fun, simple tracker keeps up on who is in space right now and provides links to each space traveler's profile.
