Setting Spaceships on Fire

NASA is conducting the Sapphire experiment to study fire behavior in space, as fires in space pose unique challenges due to the absence of gravity. The experiment involves setting a piece of cloth on fire in an unmanned spacecraft to observe how flames spread and react in microgravity. This research aims to improve fire safety for future space missions, including those to Mars. The video also highlights the importance of understanding fire dynamics in space and outlines plans for additional tests with various materials to enhance fire prevention and response strategies.

What was a significant challenge faced during the 1997 Russian space station fire?

• No communication with Earth

• Inadequate fire extinguishers

• Overheating of equipment

• Lack of oxygen

Why does a candle flame have a teardrop shape on Earth?

• Due to the color of the flame

• Because of the candle's wax composition

• Because of the gravitational pull

• Due to the presence of wind

How does gravity affect fire in space compared to Earth?

• It makes the fire burn faster

• It has no effect on the fire

• It causes the fire to form a sphere

• It extinguishes the fire quickly

What is the primary goal of the Spacecraft Fire Experiment (Sapphire)?

• To test new fire extinguishers

• To understand how fire spreads in space

• To create a new type of spacecraft

• To improve oxygen supply systems

What will the Sapphire experiment use to study fire behavior in space?

• A piece of cloth

• A container of liquid fuel

• A piece of metal

• A block of wood
