Just like athletes everywhere, astronauts have to keep in shape both on Earth and in space. Due to the lack of gravity in space, astronauts experience a decrease in muscle mass and bone density.
Just like you conduct experiments in your science class, astronauts do experiments while in space. The microgravity of space allows astronauts to carry out experiments that would not be possible in the gravity of Earth. There are more than 300 experiments currently happening aboard the International Space Station (ISS).
Have you ever hung upside down for a little while? Remember how it felt to have all the blood rush to your head? When astronauts get to space, they experience a very similar sensation, which they nickname "puffy head bird legs."
Italian Astronaut Paolo Nespoli talk to the STEM in 30 team about the different challenges he has faced in space during his time on the International Space Station.
In the latest episode of ISS Science, Astronaut Randy Bresnik explains some of the challenges astronauts face during spacewalks including extreme temperatures. Then, we stimulate the effects of extreme temperatures on metals here on Earth.
Communication is vitally important to astronauts while they are in space. Explore how experts communicate with the astronauts aboard the International Space Station in this week's STEM in 30.
On Monday, August 21, Astronaut Randy “Komrade” Bresnik will have an unbelievable view of the solar eclipse, set to pass across the United States. Bresnik will watch the solar eclipse from the International Space Station (ISS)—he should be in orbit over the U.S. at exactly the right moment.
You’ve probably heard of the National Aeronautics and Space Administration (NASA), but have you heard of the Italian Space Agency or the European Space Agency? NASA works with these groups, among others, to explore the frontiers of space together. It wasn’t always this way; Russia and the United States both devoted countless resources to beating each other to space in the 1960s. But today, through shared missions and space stations, we work cooperatively to explore the final frontier.
Showers, baths, swimming: these are all experiences most of us take for granted on Earth. There's nothing quite like experiencing the cool touch of water from the shower or jumping into a pool on a hot day. Gravity is what makes all of these experiences possible—it pushes that cool and refreshing water off your back and into the drain.
But all that changes in space. The lack of gravity causes water and soapsuds to stick to everything.
It’s not every day that an astronaut invites you to Johnson Space Center in Houston, Texas, to work with and film them training. But that’s exactly what Randy “Komrade” Bresnik did for the STEM in 30 team. In the following months we’ll be sharing his journey with you as he travels to the International Space Station (ISS) on Expeditions 52 and 53.
