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.
Hours of research by our editors, distilled into minutes of clarity.
Astronaut Bruce McCandless was the first person to ever float freely in space, completely untethered from a shuttle. How did he enter the field? What are his thoughts on current space travel? Listen to his experience and opinion firsthand in this 19-minute video.
All that exercising, and astronauts still are likely to lose a large amount of muscle mass while in microgravity. Astronauts can lose up to 20 percent of their muscle in as little as five days in space. Currently, tracking muscle loss means waiting until astronauts land to remeasure their muscle density post-trip. This article explains a NASA-backed fitness wearable that may be able to track muscle atrophy as it happens.
And why is the next cohort headed there? The geological conditions in Flagstaff, Arizona, can easily echo those of the moon, making the area a prime spot to train astronauts. This article explains how scientists crafted these training grounds and why astronomers are drawn to the nearly century-old city.
NASA's Artemis mission—the first to return humans since 1972—aims to explore the moon's water-rich south pole. Finding water is a crucial goal of NASA's Artemis program, which aims to establish a permanent, sustainable human habitat on the moon. NASA also hopes to create a refueling station by using water as a rocket propellant as well as nuclear reactors and solar farms to sustain astronauts. Obviously, significant challenges remain. This article captures the current status of plans to build a lunar base.
Astronauts' initial small step for mankind may standout, but how many steps have we taken so far? Space and moonwalks further our understanding of spaceflight, celestial bodies, and space itself. Created to resemble a constellation map, this chart...
Researchers are developing pharmaceutical solutions for astronauts, whose bodies may not respond the same way in space as they would on Earth. Similar to how microgravity causes changes to astronaut physiology, the environmental shift enables new...
