Retired NASA astronaut offers East Texas students message of persistence

TYLER, TX (KLTV) - Retired NASA astronaut Mark Kelly stepped off the Space Shuttle Endeavour in 2011 into his retirement. He did so in part to help his wife, Gabby Giffords, the former Arizona Congresswoman who survived an assassination attempt that same year.

Tuesday night, Captain Kelly spoke at the All Saints Episcopal School in Tyler as they cut the ribbon on their Center for Innovation.
