Exploring Life Detection on Mars

NASA scientist Chris McKay tests a Raman spectrometer in a cave to search for life on Mars. The cave provides insights into life preservation over geological time. The spectrometer, undergoing its first field test, uses a laser to analyze samples without damaging them. It detects organic material, suggesting possible ancient life, but further analysis is needed at NASA.

What is the primary goal of Chris McKay's mission?

• To collect rock samples

• To explore the surface of Mars

• To find evidence of life on other planets

• To test new space suits

What unique feature do the crystals provide in the search for life?

• They are easy to find

• They are lightweight

• They are colorful

• They act as time capsules

What is the Raman spectrometer primarily used for?

• Measuring temperature

• Detecting life forms

• Analyzing rock density

• Mapping terrain

How does the spectrometer detect life without damaging the crystals?

• By applying heat

• By using a laser

• By emitting sound waves

• By using a gentle brush

What happens to the light from the laser when it hits the sample?

• It changes color

• It is scattered back

• It disappears

• It is completely absorbed

Who assists McKay in the field test of the spectrometer?

• Sending it to Mars

What is McKay's reaction to the mission's outcome?

• Angry

• Disappointed

• Indifferent

• Hopeful

What does the spectrometer's detection of organic material suggest?

• Presence of water
