Space weather typically refers to charged particles ejected by the sun that can interact with Earth's atmosphere and magnetic field. However, a new study shows that humans also can change the near-Earth space environment.
According to the study, examples of human activity that can cause these changes include the use of very-low-frequency radio communications, and nuclear explosions detonated high in the atmosphere. Nuclear power

Bricks 3D Printed Using Simulated Moondust | Video

By Steve Spaleta | May 22, 2017 08:59am ET
A European Space Agency (ESA) project used focused solar heat to bake the simulated moondust, made from terrestrial volcanic material, at a temperature 1000°C to create the bricks. "Future lunar colonists could one day use the same approach to build settlements on the Moon," according to ESA.
