Space Facts II - Lunar Ranging

The video tutorial explains the work of the University of Hawaii in understanding the geophysical science of the moon and Earth. It highlights the VER Observatory's use of laser technology to measure the distance between Earth and the moon. The process involves using lasers to hit retro reflectors on the moon and measuring the time taken for the light to return. This data helps scientists analyze Earth's motion, including rotation, continental drift, and weather phenomena. The tutorial also covers the setup of the laser and telescope for lunar ranging and the role of NASA's Jet Propulsion Laboratory in data analysis.

What is the primary purpose of the VER Observatory's laser technology?

• To measure the distance between Earth and Mars

• To study the surface of the moon

• To accurately measure the distance between Earth and the moon

• To observe stars and galaxies

How does lunar ranging help scientists understand Earth's rotation?

• By analyzing the color of the moon

• By measuring the distance changes between Earth and the moon

• By observing the moon's surface features

• By tracking the moon's orbit around the sun

Which phenomenon is NOT mentioned as being studied through lunar ranging?

• Solar flares

• Earth's rotation

• Continental drift

• El Nino effect

What is the role of the receiving telescope in the lunar ranging process?

• To collect particles of laser light returning from the moon

• To send laser pulses to the moon

• To analyze the moon's surface composition

• To measure the temperature of the moon

Where is the data from the lunar ranging operation analyzed?

• Apollo 15 landing site

• Mount Holly Ochola

• NASA's Jet Propulsion Laboratory
