The show pays tribute to Abraham Lincoln and to astronauts and their support teams at NASA. The “Battle Hymn of the Republic” will play with a special sequence of blue and gray shells to celebrate the bicentennial of Lincoln’s birth. Additionally, this year marks the 40th anniversary of the first moon landing. A fireworks display choreographed to the theme from “2001: A Space Odyssey” will unfold with a sound clip from astronaut Neil Armstrong.
