NASA | The Moon's Permanently Shadowed Regions

The video explains how the moon's features are illuminated by the sun, with some areas remaining in permanent shadow due to the moon's axis. NASA's Lunar Reconnaissance Orbiter (LRO) uses various instruments to map and study these dark craters, revealing their shapes and measuring faint light from stars. The LRO also measures temperature and detects elements like hydrogen in the lunar soil, enhancing our understanding of the moon's environment.

Why do some regions on the moon remain permanently shadowed?

• The moon's axis is parallel to the sun's light.

• The moon's axis is nearly perpendicular to the sun's light.

• The moon rotates too quickly.

• The moon is too far from the sun.

What is the primary purpose of the Lola instrument on the LRO?

• To measure the moon's atmosphere.

• To create topographical maps of the moon's surface.

• To detect water on the moon.

• To capture images of the moon's surface.

How do scientists visualize the floors of the moon's craters?

• By sending astronauts to explore them.

• By using a giant flashlight.

• By creating 3D models.

• By using satellite images.

What does Laura's lamp instrument measure in the moon's craters?

• The depth of the craters.

• The presence of water.

• The temperature of the craters.

• The faint light from other stars.

Which element can the LRO's lend instrument detect in the lunar soil?

• Oxygen

• Carbon

• Hydrogen

• Nitrogen
