Events marking the 10th anniversary of the Space Shuttle Columbia disaster are being held across East Texas. Three days of events are under way in Hemphill, Texas. Belinda Gay, president of the Sabine County Columbia Memorial Committee, said Columbia is part of the fabric of her life. She was a volunteer searcher for wreckage and a meal coordinator for thousands of recovery workers who descended on her town. She said the Columbia disaster brought the space program into focus for her.
