The Imaginary Future Asteroid That Hit NYC

The video discusses the potential threat of asteroids hitting Earth and the measures taken by astronomers and space agencies to monitor and mitigate such threats. It describes a fictional asteroid impact drill conducted at a planetary defense conference, where participants simulated the discovery and response to a hazardous asteroid named 2019 PDC. The drill explored various deflection strategies, including kinetic impactors and nuclear detonations, and highlighted the challenges of limited observation windows and data. The scenario concluded with a successful deflection but a remaining fragment threatening New York City, emphasizing the need for continued monitoring and preparedness.

What was the main purpose of the asteroid impact drill conducted at the conference?

• To train astronauts for space missions

• To test new telescope technologies

• To develop new space exploration strategies

• To simulate potential asteroid impact scenarios

What was the initial estimated chance of asteroid 2019 PDC impacting Earth?

• 20%

• 5%

• 10%

• 1%

Which two methods were proposed to deflect the asteroid from its collision course?

• Chemical propulsion and ion thrusters

• Kinetic impactor and nuclear detonation

• Laser beams and gravitational pull

• Magnetic fields and solar sails

What was the main challenge in sending a reconnaissance probe to the asteroid?

• Political disagreements

• Insufficient technology

• Limited launch windows

• Lack of funding

What was the potential impact location identified by the reconnaissance probe?

• Los Angeles

• New York City

• Denver

• Miami

What was the outcome of the kinetic impactor mission?

• The asteroid was completely destroyed

• The asteroid was deflected, but a fragment remained

• The asteroid was redirected to the moon

• The mission failed to alter the asteroid's course

What is the current assessment of asteroid threats to Earth?

• Several asteroids have a high chance of impact

• No asteroids have a significant chance of impact

• Asteroids are no longer monitored

• All asteroids are deflected by Earth's atmosphere
