2. Understanding Asteroid Impacts: Risks and
Mitigation
Potential Risks
Asteroid collisions can cause
regional to global devastation.
Detection Efforts
Global networks track near-Earth
objects to forecast threats.
Mitigation Strategies
Deflection missions and
evacuation plans reduce impact
damage.
3. Solar Flares: Forecasting
and Protecting
Infrastructure
Monitoring
Space weather satellites detect solar flare activity in real-time.
Forecasting
Scientists analyze solar patterns to predict flare intensity.
Protection
Grid operators implement protocols to safeguard electrical
systems.
4. Cosmic Radiation: Health
Impacts and Shielding
Strategies
Health Risks
Exposure increases cancer risk
and cellular damage in
humans.
Shielding Methods
Advanced materials and
spacecraft design reduce
radiation exposure.
Monitoring
Personal dosimeters track radiation doses for astronauts and pilots.
5. Case Study: The 2013 Chelyabinsk Meteor Event
– Background and Impact
Background
The meteor entered Earth's atmosphere over Russia in
February 2013.
It was about 20 meters in diameter and traveled at high
velocity.
Impact
• Shockwave shattered windows and injured 1,500 people.
• Event caused significant structural damage to buildings.
• It was the largest recorded meteor blast since Tunguska
(1908).
6. Chelyabinsk Meteor: Lessons Learned for Disaster
Preparedness
Early Warning Importance
Need for improved global monitoring of smaller meteors.
Infrastructure Resilience
Focus on strengthening windows and buildings against shockwaves.
Public Awareness
Educating communities on meteor safety and response is critical.
7. Integrating Planetary Hazard
Awareness into Disaster
Management Plans
Risk Assessment
Identify planetary hazard scenarios relevant to the region.
Preparedness
Develop response protocols and training exercises.
Collaboration
Coordinate with space agencies and meteorological services.
Communication
Establish clear public alert systems for planetary events.
