How tall are you? Are you sure you know the answer? Studies show that the height of an astronaut increases approximately 3% over the first 3 to 4 days of weightlessness in space. As soon as …
In preparation for space travel, astronauts invest many hours in practicing their hand-eye reaction time. Operating the robotic arm on the International Space Station requires crew members to have quick reaction times. Crew members must …
In a reduced gravity environment, astronauts are unable to walk like they do on Earth. Instead, they coordinate their hands, arms, and feet to pull and push themselves from one place to another. Whether inside …
In the microgravity environment of the International Space Station astronauts can perform spectacular rolls. Here on Earth, because of gravity these rolls are not as easy. In Space Rock-n-Roll, your team will perform a series of …
One exercise device that is regularly used by astronauts on the International Space Station is the cycle ergometer. The cycle provides bone strength exercise for the legs. When the large leg muscles work they need …
In a reduced gravity environment, muscles and bones can become weak, so astronauts must engage in strength training to counter the weakening effect of microgravity. Before, during, and after living in space astronauts work closely …
On Earth, we use a variety of cues to sense the position of our bodies, while stationary or moving. We use touch and pressure cues (such as weight on our feet) and visual cues (such …
On Earth, humans experience the effects of gravity pulling on the human body which applies a constant force, or loading effect. This constant force is essential for building the healthy, strong bones we need on …
Astronauts’ training takes into account the influence of gravity because during their mission they will be in a free-fall microgravity environment. When astronauts are back on Earth after a six-month stay on the International Space …
To explore the Moon and Mars, astronauts must complete the tasks of walking to collection sites, taking samples, carrying science experiments, and safely lifting objects they discover to return to base station. In order to …
