Space Debris and Its Implications

Why is space junk a significant concern for life on Earth?

• It causes light pollution.

• It increases Earth's gravitational pull.

• It disrupts satellite operations crucial for daily life.

• It affects the ozone layer.

What was Donald Kesler's key insight about space debris?

• Space debris can be used as a resource.

• Space debris is not a threat to satellites.

• Space debris will eventually fall back to Earth.

• Collisions in space can lead to an exponential increase in debris.

How did the United States Air Force respond to the threat of space debris?

• By ignoring the threat.

• By removing all debris manually.

• By tracking debris larger than a baseball.

• By launching more satellites.

What was the impact of the 2007 Chinese anti-satellite missile test?

• It reduced space debris by 30%.

• It had no impact on space debris.

• It created a new type of satellite.

• It increased space debris by almost 30%.

What is a potential consequence of a kinetic war in space?

• It would improve satellite communications.

• It would have no impact on space operations.

• It would create an unmanageable debris field.

• It would clear space debris.

What happened during the 2009 satellite collision?

• It created 4,000 more pieces of debris.

• It reduced the number of satellites.

• It had no impact on space debris.

• It improved satellite technology.

What was the purpose of the Earth-based experiment simulating space collisions?

• To test new space technology.

• To reduce space debris.

• To understand the effects of space debris collisions.

• To create new satellites.

What was the result of firing a soup can-sized object into a metal tank?

• The tank was turned into a piece of modern art.

• The tank remained intact.

• The tank was vaporized.

• The tank was dented slightly.

What does the snowball effect in space debris refer to?

• The formation of new planets.

• The gradual melting of space ice.

• The exponential increase in debris from collisions.

• The cooling of space temperatures.

How does the energy of small debris particles compare to weapons?

• They have no energy.

• They are like a 357 Magnum.

• They are like a water pistol.

• They are like a firecracker.
