Exploring Lunar Telescopes and Challenges

What was the significance of the Chang'E 3 mission?

• It was the first manned mission to Mars.

• It included the first soft landing on the moon since 1976.

• It was the first mission to land on an asteroid.

• It was the first mission to explore the sun.

Why is the moon an ideal location for telescopes?

• It has a thick atmosphere that enhances image clarity.

• It is closer to the sun, providing more light.

• It allows access to the entire electromagnetic spectrum.

• It has a magnetic field that protects telescopes.

What is the significance of the moon's long nights for astronomy?

• They help in calibrating telescopes with Earth's atmosphere.

• They provide more sunlight for solar-powered telescopes.

• They reduce the need for artificial lighting on the moon.

• They allow for continuous observation without interruption.

What was one of the main challenges faced by the Yutu rover?

• Collision with other lunar rovers.

• Extreme temperature fluctuations on the moon.

• Lack of communication with Earth.

• Interference from Earth's atmosphere.

How might moondust be used in constructing lunar telescopes?

• To power solar panels.

• As a fuel source for rockets.

• To create a concrete-like material for mirrors.

• As a replacement for telescope lenses.

What is a potential advantage of liquid mirror telescopes on the moon?

• They can be much larger due to lower gravity.

• They are unaffected by lunar dust.

• They can point in any direction without limitations.

• They require no maintenance.

What is the main limitation of liquid mirror telescopes?

• They require constant human supervision.

• They can only point straight up.

• They cannot focus light properly.

• They are too expensive to build.

What is a potential benefit of using ionic liquids in lunar telescopes?

• They are lighter than mercury.

• They can form larger mirrors due to lower gravity.

• They can evaporate quickly in low pressure.

• They are more expensive than traditional materials.

What is a major advantage of building telescopes directly on the moon?

• There is no fundamental limit to their size.

• They can be easily transported back to Earth.

• They are protected by the moon's atmosphere.

• They can be powered by solar energy.

What is the goal of the International Lunar Observatory Association?

• To build a space station on Mars.

• To set up an optical telescope on the moon.

• To launch a satellite to explore Jupiter.

• To create a new type of space shuttle.
