NASA | The Mystery of Martian Methane

The video discusses the discovery of methane on Mars, highlighting its seasonal release from specific vents. The origins of this methane are explored, considering both biological and geochemical processes. NASA's missions aim to investigate these findings further, with the Mars Science Laboratory playing a key role in understanding whether life ever existed on Mars.

What is surprising about the methane detected on Mars?

• It is produced by volcanic activity.

• It is found in the form of ice.

• It is generated recently and released seasonally.

• It is found only in the southern hemisphere.

Which of the following is a potential biological source of methane on Mars?

• Wind erosion

• Microbial activity

• Volcanic eruptions

• Solar radiation

What geochemical process could lead to methane production on Mars?

• Carbon dioxide combining with water under high temperatures and pressures

• Magnetic field interactions

• Photosynthesis

• Evaporation of water

What is one of the key objectives of NASA's Mars Science Laboratory?

• To determine if life ever arose on Mars

• To study the Martian weather patterns

• To mine resources from Mars

• To establish a human colony on Mars

What do the identified signposts on Mars indicate?

• Locations of water reservoirs

• Regions with abundant vegetation

• Potential sites for future exploration
