During the presentation, a NASA presenter reminds the visitors that these satellites must be launched into space.
Then the speakers play the sound of a rocket taking off. The sound moves across curve of the structure, giving a realistic impression of movement.
Then the calming sounds return. Toward the end, a voice calls out the names of NASA satellites currently studying the Earth as well as the International Space Station (ISS). The eighth annual World Science Festival, ending on Sunday, has brought together the brightest scientists with the most interesting jobs on the planet.
