Scientists suggest launching moon dust into space to shield us from the sun
It sounds like a science fiction plot from the 1950s: In the far future year of 2023, one researcher has proposed we blast dust off the moon to shield us from the sun.
But no - scientists from the University of Utah have calculated that it would be theoretically possible to shoot moon dust into space to block the sun's rays before they reach Earth, in an attempt to stop the planet from warming.
The researchers say dust grains in the right place in space could shade the Earth for up to a week, and moon dust takes less energy to launch than dust from Earth.
Using moon dust also avoids any long-term impacts on Earth or its atmosphere.
And given the dust clouds would disperse relatively quickly, it would allow for some level of control over the shading between seasons...
