Space agency NASA has dished-out $5 million to seven concepts for future space exploration—and they include some exceptionally creative ideas. They include space habitats made from fungi, “climbing robots” that could build a radio telescope on the far side of the Moon, a “swarm” of spacecraft to explore the clouds of Venus and spacecraft that

As reported a few days ago, NASA is about to make aviation history when, on Sunday, it conducts the first controlled, powered and autonomous flight on another planet. Almost 118 years after Orville and Wilbur Wright’s historic first flight at Kill Devil Hills near Kitty Hawk, North Carolina, NASA’s Mars Helicopter—nicknamed “Ingenuity”—will perform a short flight
