Q&A

• Who is planning to launch Sentinel, and what does it signify?

  A private organization is planning to launch Sentinel to find and protect Earth from asteroids, signifying the advancement in technology that enables measures to protect our planet.

• What is the purpose of the spacecraft named Sentinel?

  The spacecraft named Sentinel is being built to track and find asteroids in the Solar System to prevent potential impacts on Earth. It aims to view the Solar System in infrared and track moving objects, with an expected discovery of over 10,000 asteroids in the first month of operation.

• Why are we not actively searching for asteroids despite knowing how to deflect them?

  Despite knowing how to deflect asteroids, lack of funding hinders the active search for them. A space telescope is needed to find asteroids, but the cost is a barrier to action.

• Why is early detection of asteroids important, and what is the challenge in surveying the Solar System?

  Early detection of asteroids is crucial for deflection, and the vastness of the Solar System presents a challenge in surveying it for undiscovered asteroids.

• What efforts are being made to address the problem of deflecting asteroids?

  Efforts are being made to work on the problem of deflecting asteroids, and it's not as difficult as previously thought. Concepts like the gravity tractor and controllable ways of deflecting asteroids are being explored.

• What was the Tunguska impact in Siberia, and why is it significant?

  The Tunguska impact in Siberia released an enormous amount of energy, causing devastation over a large area, highlighting the potential dangers of asteroid impacts.

• Why are asteroids important?

  Asteroids are important as they frequently hit the Earth, posing potential threats and causing devastating impacts.

• What is Ed Lu building with the B612 Foundation to protect the Earth from threatening asteroids?

  Ed Lu is building a space telescope called Sentinel with the B612 Foundation to protect the Earth from threatening asteroids by finding and tracking them before they impact the Earth.

• 00:00 Ed Lu is building a space telescope called Sentinel with the B612 Foundation to protect the Earth from threatening asteroids by finding and tracking them before they impact the Earth. Asteroids are important as they hit the Earth frequently.
• 02:31 An asteroid impact in Tunguska, Siberia, released an enormous amount of energy, causing devastation over a large area. Efforts are being made to work on the problem of deflecting asteroids, and it's not as difficult as previously thought.
