As reported by the Italian webiste everyeye.it, sensational news is bouncing across the planet: some (crazy?) scientists would like to blow up the moon, to fight climate change. Scientists are looking for solutions to avoid climate change, but blowing up the moon is undoubtedly the most sensational.
The goal on the part of scientists would be to blast a steady stream of dust from its lunar surface, and not destroy the satellite completely. Researchers and scientists would like to use the lunar dust as a sort of refractive to reduce the amount of sunlight hitting the Earth.
So scientists figured that a 10 billion kilogram dust cloud could do much the same job and even has advantages over more technical space projects. According to the researchers calculations, a few orbits of these dusts could create a necessary shadow for several days.
So blasting moondust right between the Sun and Earth could be the most cost-effective and risk-free method of reducing our planet's temperature until we reduce emissions. A small cloud of lunar dust between the sun and the Earth would be sufficient to attenuate the sun's rays by up to almost 2%.
And so far so great. Too bad the undertaking would involve extracting tons of dust from the moon, sifting it, loading it on a ballistic device and firing it at the Lagrange point, where perhaps even placing a new new space station with dust bombs on board to be launched from time to time.
There have been various solar shield projects for decades, but many scientists are skeptical. Some say tinkering with geoengineering is dangerous, others say it's a useless distraction from the urgency of tackling global warming, still others allow the most polluting nations to find excuses not to stop.
The scientists, who are proposing a geo-engineering solution to global warming, started from the analysis of the Earth-Sun L1 Lagrange point, one of the points discovered by the 18th century mathematician, in which the gravitational attraction of the two celestial bodies balances therefore, if an object is placed in the way, it maintains a stable position.
Then they considered what to interpose: the material. They settled on moon dust whose grains are of optimal size and composition to effectively scatter sunlight away from Earth.
