Fire, Lightning, and Crystals in Space: 20 Years on the ISS

The video explores the unique experiments conducted on the International Space Station (ISS) over the past 20 years. It highlights research on fire behavior in microgravity, the study of thunderstorms and gamma rays, and the growth of crystals for semiconductors. These experiments aim to improve safety in space, enhance weather predictions, and develop better technology on Earth.

What is the primary reason fire behaves differently in space compared to Earth?

• Lack of oxygen in space

• Different chemical reactions

• Higher temperatures in space

• Absence of convection in microgravity

What is the purpose of the Burning and Suppression of Solids investigation on the ISS?

• To understand fire behavior in microgravity

• To develop new types of fire extinguishers

• To study the effects of fire on spacecraft materials

• To create new fire suppression technologies

What are terrestrial gamma ray flashes (TGF) associated with?

• Earthquakes

• Volcanic eruptions

• Thunderstorms

• Solar flares

How do TGFs form according to the research conducted on the ISS?

• From volcanic ash clouds

• From the collision of asteroids

• In front of a lightning bolt

• Due to solar wind interactions

Why is crystal growth more uniform in space?

• Absence of convection in microgravity

• Higher temperatures in space

• Different chemical composition

• Faster cooling rates
