Colorado-built spacecraft OSIRIS-REx stalking Bennu asteroid for brief encounter

A Colorado-developed spacecraft designed to follow, study and briefly touch a large asteroid with an orbit near Earth is set to take off Thursday evening from Cape Canaveral in Florida.
OSIRIS-REx, which stands for Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer, has a mission of studying the Bennu asteroid and snatching a sample from its surface.
NASA is scheduled to launch the craft within a two-hour window starting at 5:05 p.m
