What does outer space sound like? Hear NASA's satellite symphony at the Huntington

It could be the start of a Steven Spielberg sci-fi film: A boy walks into a shimmering, aluminum garden pavilion surrounded by lush palms and succulent-lined footpaths. There's a massive crater in the ceiling, open to the blue sky, and the boy cranes his neck backward to gaze at the heavens as puffy white clouds sail past. NASA's 19 earth science satellites, which are quietly circling the planet, seem to be communicating with visitors of the pavilion, their combined "voices" creating a cacophonous concert that now echoes inside the domed chamber. This is the West Coast debut of NASA Orbit Pavilion, on view at the Huntington Library, Art Collections, and Botanical Gardens in San Marino through Feb. 27. The structure, in the shape of a giant seashell, houses a sound installation that tracks the movement of the International Space Station and NASA's satellites as they make 90-minute trips around the Earth.
