On Feb. 9, NASA's OSIRIS-REx spacecraft began searching for an elusive type of near-Earth object known as Earth-Trojan asteroids. The spacecraft, currently on a two-year outbound journey to the asteroid Bennu, will spend nearly two weeks looking for evidence of these small bodies.
A group of concerned engineers and scientists is investigating a space-based method to offset global warming. Their concept is called Heliocentric Earth-Lagrangian Interception of Sunlight (HELIOS), a flotilla of perhaps many thousands of kilometer-square sun sails that, once placed at the Sun-Earth Lagrange (SEL1) point, would reduce the amount of sunlight striking the Earth.
