Searching For Life On Mars

The video discusses a Mars mission aimed at detecting methane, a gas that shouldn't naturally exist on Mars. The mission uses the Nomad instrument, which includes spectrometers to analyze sunlight passing through the Martian atmosphere. The Exo Mars mission consists of an orbiter and a Rover, with the latter designed to search for past or present life. The Rover is tested in a Mars-like environment to ensure its autonomous capabilities. Detecting methane could indicate geological or biological activity, both of which are unexpected on modern Mars. The Rover's drill can reach meters below the surface, crucial for finding signs of life.

Why is methane considered an unusual gas to find in the Martian atmosphere?

• It is a sign of water presence.

• It is a byproduct of human activity.

• It should not naturally exist on Mars.

• It is a common gas on Earth.

What is the primary function of the Nomad instrument on the Mars orbiter?

• To analyze sunlight and identify gases.

• To communicate with Earth.

• To capture images of Mars' surface.

• To measure Mars' temperature.

What is the main objective of the Exo Mars rover mission?

• To search for signs of life.

• To collect rock samples.

• To establish a human base.

• To map the surface of Mars.

Why is the Mars rover equipped with a drill?

• To dig for water.

• To collect surface dust.

• To reach deeper layers for life detection.

• To create holes for planting sensors.

What could the presence of methane on Mars indicate?

• Atmospheric storms.

• Human activity on Mars.

• Geological or biological activity.

• Presence of water bodies.
