THURSDAY, JULY 23, 1998 (4:18 PM EDT)
NOTE: Shuttle Discovery’s main engine heat shields were removed July 9 and the engines were pulled July 10. The orbiter maneuvering system (OMS) has undergone evaluation and troubleshooting in recent weeks due to problem indications during the STS-91 flight. Three of Discovery’s right-hand OMS pod thrusters have been replaced and leak checks are in work today. Also, a propellant valve position indicator on the left-hand OMS pod was replaced yesterday. Earlier this week, the main propulsion system’s liquid oxygen system underwent routine leak and functional tests. Today, preparations are under way to cut out the orbiter’s leaky water relief valve. Removal of the fuel cell No. 3 relief valve occurs tomorrow. STS-95 SCHEDULED OPERATIONAL MILESTONES (dates are target only):
