Modifications and upgrades are underway inside the Astronaut Crew Quarters in the Neil Armstrong Operations and Checkout Building at NASA's Kennedy Space Center in Florida. New carpeting and trim has been installed along a hallway and into some of the bedrooms. Photos of astronauts' families line the walls. The crew quarters are being prepared for the next generation of space explorers. The historic facility housed Apollo and space shuttle astronauts before and after their missions into space.
