Department of Planetary Defense

Mission: Defend Earth from natural extraterrestrial threats. These threats include

* Impacts from large comets and meteors.

* Energetic particle ejections from supernovas or solar anomalies.

* Electromagnetic exposure from cosmic radiation or solar flares.

The Department would provide a cohesive approach to resolving these threats. The Department would direct, coordinate and fund Planetary Defense efforts within various agencies including NASA, USAF and FEMA. The Department through a unified approach would coordinate Detection & Threat Analysis (NASA), Threat Mitigation (USAF) and Defense Preparedness (FEMA).

Near Term Goals (Comet Impact Threat):

* Understand the impact threat.

Internal structure and composition of large comets & meteors.

Comet evolutionary breakdown.

Detailed threat analysis of large impact events.

* Develop a space based detection system.

* Develop a mitigation approach

Explore conceptual mitigation systems tailored towards threats.

Develop and test prototype mitigation systems.

* Develop a comprehensive impact shelter plan

Charter survey teams to establish the framework of initial shelter sites.
