Preparedness without panic
A large confirmed impact threat is rare. Still, practical readiness is useful for many hazards: severe weather, outages, evacuations, communications failures, and family emergencies.
Public Guide 05
Asteroid Impact Preparedness
Asteroid impact preparedness is best treated as practical all-hazards readiness: communication plans, emergency supplies, trusted alerts, and calm family decision-making.
Follow official instructions
If an official alert is issued, follow local emergency management and national warning systems. TESS educational pages can explain context, but they do not replace emergency orders.
Practical workflow
Build a contact plan
Decide how family members will communicate if phones or internet are unreliable.
Keep basic supplies
Water, food, medicine, lighting, batteries, radio, chargers, documents, and first-aid basics help in many emergencies.
Know local alerts
Enable official local emergency alerts and learn evacuation/shelter guidance for your area.
Reduce misinformation
Share official links and avoid forwarding unsourced claims.
Plan for pets and family needs
Include medication, mobility, accessibility, children, and pet requirements.
Review regularly
Update supplies, contacts, and documents on a repeating schedule.
Practical supplies
- Water and shelf-stable food.
- Flashlights, batteries, radio, chargers.
- First aid, medications, copies of key documents.
Practical decisions
- Where to meet.
- Who to contact.
- Which official alert sources to trust.
Authoritative sources
Use official sources first. TESS pages are public education and mission-support summaries, not official emergency orders.
