The European Space Agency's Hera spacecraft lifted off from Cape Canaveral Space Force Station in Florida. The spacecraft will do what the agency is calling a crash scene investigation of two asteroids. One of the asteroids is smaller and orbits a larger one. The smaller asteroid was struck by a NASA spacecraft as part of a double asteroid redirection test.
