Stitched together are images of the entire moon as taken by the Lunar Reconnaissance Orbiter. The two sides of our space neighbor are quite different in appearance thanks to the Moon being tidally locked to Earth.
Tuesday, March 6, if you want a bit more precision. You may well ask, “How do we know this?” Well, take a few minutes out of your busy schedule and be illuminated by the video below:
It may well be that Tuesday Afternoon by The Moody Blues could be heard, echoing through time in the background.
then you need to learn about the Carrington Event, and the next global blackout. Really.
The video above is good as far as it goes, but it doesn’t make the problems of recovery scary enough. Large electrical transformers cannot simply be ordered off the shelf. Some of the parts and materials used in them are in short supply and it can take over a year to get one delivered – assuming there is no blackout affecting the manufacturing and transportation of the unit. Repairing and/or replacing electrical grid components will be a nightmare of epic proportions.
I could go on and on discussing how costly and lengthy recovery from a Carrington Event will be, but doing what we can to harden our electrical distribution network will go a long way toward mitigating the other problems that will arise. It is easy to think about roads, bridges, and piplelines when thinking about infrastructure updates, but the electrical grid needs lots of attention.
Experts say there is a 12% chance (roughly 1 in 8) of a Carrington-level event happening by 2022.
