Electricity is our civilization’s lifeblood, and as we become more dependent upon electronics and computers, life cannot exist without the “grid.” The Huntsville Alabama L5 Society (HAL5), a chapter of the National Space Society (NSS), was founded to promote the ultimate goal of turning humanity into a spacefaring civilization. However, before we can hope to accomplish that, we must ensure our civilization survives against the more immediate but preventable threat of a loss of the power grid.

The fragility of our power grid may be the biggest roadblock to our dreams, and threat to the safety of our families. There are numerous root causes that could bring down our power grid to an extent that our nation and world would not be likely to recover from in our lifetimes – denying us the dream of space settlement for generations. The likelihood of this occurring is actually very high within the next couple of decades. The good news is that if we act now we can take steps to ensure our grid is hardened to the point that a grid down would be far less extensive and recoverable. Cyber-attacks, sabotage, geomagnetic super-storms, coronal mass ejections (CME) from the sun, and electromagnetic pulse (EMP) from the high-altitude detonation of a nuclear weapon pose severe threats to our electric power grid. The first two events are just a matter of time.

It was only 62 years between the 1859 Carrington Event and the Railroad Event CME of 1921. It has been 95 years since then. The probability for a Carrington Event CME has been determined by NASA to be 12% per decade. We had a near miss from a CME summer before last when a CME barely missed the Earth in its orbit.

Several nation states and organizations have both the means and the motives to bring down our power grid through Cyber, Physical Attack, and EMP. It is in their doctrine, and they practice doing it. What needs to be done to secure our future is actually not such a great leap. We just need to make sure our electrical grid is protected and quickly. We space advocates have technical and political savvy which is unique to pushing this world saving agenda forward.

For us and our future generations, steps must be take to ensure humanity's our future. The universe is filled with countless wonders that beckoning us.
