Joseph Pelton, former dean of the International Space University, in Illkirch-Graffenstaden in France, has called for scientists to take action by creating a massive magnetic shield to protect Earth. In a new paper published in ROOM, Dr Joseph Pelton, said that over the course of the last half century, the world has finally begun to learn that a massive asteroid or comet strike could create havoc and ruin, on perhaps a planetary scale. What we don't have is a global understanding that there is a much more likely danger that is increasing over time and is a very real cosmic danger that could knock out our electric power grids, kill key satellite systems for communications and navigation and defence.
The Earth protects itself from solar storms using an invisible shield known as the 'magnetosphere'. But because Earth's magnetic poles are continually moving, the magnetosphere is weakening. This means our planet is increasingly vulnerable to the potentially devastating effects of solar flares. A solar flare's 'killer electrons' can travel at up to several million miles per hour towards Earth. If this material collides with the Earth's magnetic field, it can affect many technologies, including satellites orbiting the planet, and radars.
Dr Pelton also warned that a storm emanating from the Sun could knock out the time synchronisation of the global Internet, which is essential for the system to continue to function as it does. However, he says that if scientists could create a mega-structure, with an huge electro-magnetic shield, it could protect the Earth from a massive solar storm. The structure could also have other purposes, such as incorporating solar power satellites which could beam clean energy back to Earth.
He says that it is time for those leading our space agencies to consider what technologies they might conceive and implement to save Earth and the human race.
