After the explosion of the Space Shuttle Columbia over East Texas in February 2003, NASA's National Scientific Balloon Facility became the collection point for all shuttle debris recovered over thousands of square miles. Three years later, in February 2006, the facility was officially renamed the Columbia Scientific Balloon Facility in honor of the astronauts who died aboard the shuttle. The new sign appears in front of the facility (top, at the renaming ceremony); on paraphernalia such as caps, shirts, and bumper stickers; and even on the tail of a $2-million airplane owned by CSBF (bottom).
