Space Shuttle 3% Scale Model in 9-by 7-Foot Wind Tunnel This image (taken in late March 2006) show a three-percent scale model of the Space Shuttle, which has been undergoing wind tunnel tests at NASA Ames Research Center, Moffett Field, Calif., in the Unitary Wind Tunnel Complex to provide data that will aid NASA in deciding if the protuberance air load (PAL) ramps will be removed from the external tank for the next shuttle launch, STS-121, now scheduled for July 2006. |
