Moon Phases and Space Exploration

Ann McLean, an astronaut, introduces the concept of moon phases and their 30-day cycle. She explains the relative distances of the Earth, space station, moon, and sun. A demonstration shows how moon phases appear from Earth, emphasizing the role of sunlight reflection. The video also discusses how astronauts on the space station observe the same moon phases and use them for research, particularly for NASA's Artemis program. Viewers are encouraged to observe the moon phases and learn how to spot the space station.

Who is Ann McLean?

What causes the different phases of the moon?

• The moon's distance from the sun

• The moon's orbit around Earth and Earth's rotation

• The sun's position in the sky

• The Earth's shadow on the moon

What is the phase called when the moon appears completely dark?

• First Quarter

• Waxing Gibbous

• New Moon

How do astronauts on the International Space Station view the moon phases?

• With a telescope for better clarity

• They cannot see the moon phases

• The same as on Earth but without atmospheric interference

• Differently from Earth due to their proximity

What is the purpose of observing moon phases on the space station?

• To predict weather patterns

• To assist in the Artemis program

• To study the sun's effects on the moon

• To track the space station's orbit

What is the Artemis program aiming to achieve?

• Send astronauts to Mars

• Study the Earth's atmosphere

• Return astronauts to the Moon

• Build a new space station

How can you find out when the space station will fly by?

• By contacting NASA directly

• By checking the weather forecast

• By observing the moon phases

• By signing up at spotthestation.nasa.gov

What should you do the next time you're outside at night?
