China’s Tiangong-1 space station fell back down to Earth this weekend, but there was no need to duck and cover. Most of the space lab burned up during re-entry, before landing in the Pacific Ocean.

What is it like to train as an astronaut? Victor Glover, part of NASA’s 2013 astronaut class, is one of the few who knows what it’s like to prepare for a journey beyond Earth’s atmosphere.

If you were freefalling back to Earth from space, would you want to rely on a couple of parachutes and some rockets to protect you from crashing? As crazy as it sounds, that is what allows astronauts aboard the Russian Soyuz capsules to safely return to Earth.

Did you know that some of the coolest photos of Earth from space were not actually taken by satellites? Many were taken by astronauts aboard the International Space Station (ISS). In fact, part of the astronaut training program focuses on how to take photos in space.

After all the food has been cleared away, and the good dishes are set aside for the next holiday, a question still remains—what do you do with all your Thanksgiving leftovers? When faced with yet another turkey sandwich, take some inspiration from the creative culinary tastes of astronauts aboard the International Space Station (ISS).

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.
