A new breed of aviators is innovating new ways to fly from clean and green electric aircraft to autonomous sky taxis.

During World War I, several new innovations emerged on the battlefield and proved crucial to breaking the stalemate of trench warfare. High on the list was the tank and the airplane.

When it comes to space exploration, expect the unexpected. As OSIRIS-REx approached asteroid Bennu, scientists were surprised to find a loosely packed rubble pile. This week, we get a closer look at Bennu and the surprises it holds in store.
