On platforms suspended from the top of the 525-foot-high VAB, workers use rollers and brushes to repaint the NASA logo on the southeast side of the Vehicle Assembly Building. Known as the "meatball," the logo measures 110 feet by 132 feet, or about 12,300 square feet. The U.S. flag is also being repainted. The flag spans an area 209 feet by 110 feet, or about 23, 437 square feet. Each stripe is 9 feet wide and each star is 6 feet in diameter. The flag and logo were last painted in 1998, honoring NASA's 40th anniversary.
