KENNEDY SPACE CENTER, FLA. -- This closeup shows four of the nine solid rocket boosters being mated to the Delta II first stage on Launch Pad 17-B at Cape Canaveral Air Force Station for launch of the Dawn spacecraft. Dawn's goal is to characterize the conditions and processes of the solar system's earliest epoch 4.5 billion years ago by investigating in detail two of the largest asteroids, Ceres and Vesta. They reside between Mars and Jupiter in the asteroid belt. Launch is targeted for July 7. Photo credit: NASA/Jim Grossmann
