• It is the most abundant element on Earth.

Why is helium used in rocket engines?

• It is lighter than air, helping rockets to lift off.

• It can push on cryo fuels without reacting or freezing.

• It is cheaper than other gases.

• It reacts with cryo fuels to produce energy.

How does helium help in detecting leaks in spacesuits?

• It reacts with oxygen to form visible bubbles.

• Its small atoms can pass through tiny fractures.

• It emits a sound when escaping.

• It changes color when exposed to air.

What is the primary source of helium on Earth?

• Mining from helium-rich rocks.

• Direct extraction from the atmosphere.

• Byproduct of natural gas extraction.

• Synthesis in laboratories.

What recent developments have helped alleviate the helium shortage?

• Increased helium production from seawater.
