Life aboard the International Space Station is very different from life on Earth. For example, astronauts experience a whole new perspective because they see Earth and space from above the atmosphere. In this video segment adapted from NASA, watch and listen as Expedition 8 crew members Mike Foale (Commander and NASA Science Officer) and Alexander Kaleri (Flight Engineer) are interviewed by Japanese students.

This video is available in both English and Spanish audio, along with corresponding closed captions.

Earth System: Drought and Air Quality

Droughts claim more victims each year than any other natural disaster. Depending on where it occurs and how long it persists, the cost of a drought can run into the billions of dollars. Droughts cause more than economic hardship, however. As this video segment adapted from NASA's Goddard Space Flight Center demonstrates, droughts have a complex web of impacts that also affect us socially and environmentally.

Galileo on the Moon

Galileo used thought experiments to test many assumptions, including the notion that heavy objects fall more quickly than lighter objects when they are dropped. Lacking access to either a vacuum chamber or a planetary body that has no atmosphere, he nevertheless correctly predicted that all falling objects would accelerate at the same rate in the absence of air resistance. In this video segment from NASA, astronaut David Scott demonstrates the correctness of Galileo's prediction.
