Mitigation is the effort to reduce loss of life and property by lessening the impact of disasters. Mitigation is taking action now—before the next disaster—to reduce human and financial consequences later (analyzing risk, reducing risk, insuring against risk).
In this Program, Disaster Playground will address a series of speculative situations to space experts and Incident Response Specialists. Disaster Playground will investigate how they will implement Disaster Mitigation Techniques (until then never tested) in the case of hazardous asteroids.
- 5 Days warning from a small object 1-10 metres in diameter
- 5 Weeks warning from a small NEO (Near Earth Object) 10-25 metres in diameter
- Un-notified and no prior warning for modest size NEO 10-100 metres in diameter
- 5 years warning from a dangerously large NEO 100 to 500
- 20-30 years warning from a dangerously large NEO 30->100 metres in diameter
- 100 years prediction of a possible impact from a potentially civilisation and species-destroying NEO
- Short term warning (less than a few years) by a civilisation and species destroying NEO.
Different mitigation techniques in place:
- Kinetic Impactor
- Blast Defection
- Combined methods
- Gravity Tractor
Alternative methods for mitigation:
- Moving asteroids with lasers
- Focusing the sun energy
- Changing the asteroid thermal properties
- Electrostatic pushing
- Reflective white paint
Other mitigation methods:
- Where are we with the nuclear option?
- What if a rubble pile asteroid explodes into several pieces?
- Are there various methods for defense?
- How are these mitigation methods tested?
- How are these methods designed without being tested first?
