NASA | The Moon's Permanently Shadowed Regions

The video discusses how different features of the moon are illuminated by the sun, with some areas remaining in permanent shadow due to the moon's axis. NASA's Lunar Reconnaissance Orbiter (LRO) provides detailed maps of these craters using its instruments. The video highlights the use of LRO's Lola, Laura's lamp, and diviner instruments to study the moon's surface, temperature, and elements like hydrogen. The ongoing research aims to enhance our understanding of the moon and uncover new discoveries.

Why do some regions on the moon remain permanently shadowed?

• The moon is too far from the sun.

• The moon rotates too quickly.

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

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

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

• To detect water on the moon.

• To capture images of the moon's surface.

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

• To measure the temperature of the moon's surface.

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

• By using a giant flashlight.

• By using satellite images.

• By sending astronauts to explore.

• By creating 3D models.

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

• The depth of the craters.

• The speed of neutrons.

• The temperature of the craters.

• The faint light from other stars.

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

• Nitrogen

• Oxygen

• Carbon

• Hydrogen
