 **The only detection available for PHO’s are radar telescopes that can see a shallow distance from Earth’s surface. More power is needed.** Bucknam and Gold in 08 [Mark and Robert “Survival” (00396338); Oct/Nov2008, Vol. 50 Issue 5, p141-156, 16p PN] [PHO - potentially hazardous object]  Such a mission would cost on the order of a few hundred million dollars.This could save years of worrying, or give us extra years to prepare and act.

 * Plan: The United States Federal Government should fully fund and implement a space based infrared sensor in a Venus-like orbit for the purposes of asteroid detection **

Bucknam and Gold in 08 [Mark and Robert “Survival” (00396338); Oct/Nov2008, Vol. 50 Issue 5, p141-156, 16p PN] [PHO - potentially hazardous object] The cost of such a system is on the order of $1bn, and the harsh space environment would likely limit its useful life to around seven to ten years.14
 * Putting an infrared sensor in a Venus-like orbit would increase detection methods by 180% and could detect PHO’s, which threaten Earth. **

Keim 09 (How to Defend Earth Against an Asteroid Strike By Brandon Keim March 27, 2009, is a Wired Science reporter and freelance journalist []  G.L) Without early discovery, there are no options. All the deflection technology in the world will not save you if you haven’t discovered the asteroid before it comes to you."
