KENNEDY SPACE CENTER, FLA. - In the Rotation Processing and Surge Facility, an SRB solid segment is lowered onto a rail car for shipment to Utah where it will be tested. The segment was part of the STS-114 stack. It is the first time actual flight segments that had been stacked for flight in the VAB are being returned to Utah for testing. It will undergo firing, which will enable inspectors to check the viability of the solid and verify the life expectancy for stacked segments.
