      * Change from earlier status
      
      NOTE:  Efforts continue to close-out the aft engine compartment with the aft 
      doors scheduled for installation Friday. A functional check of the 
      contingency spacesuits was conducted yesterday. Suit no. 1 passed the test, 
      however, the second suit developed a problem and had to be removed from the 
      orbiter. A replacement suit is scheduled to arrive from Johnson Space Center 
      early next week. No spacewalk is scheduled for this mission. However, 
      spacesuits are flown on each mission for use during possible contingency 
      situations.

      MISSION: STS-79 -- 4th MIR DOCKING
      
      VEHICLE: Atlantis/OV-104
      LOCATION:  Orbiter Processing Facility bay 1
      TARGET LAUNCH DATE: July 31 at about 11:42 p.m.
      LAUNCH WINDOW: 7-10 minutes

      NOTE:  The mechanical installation of fuel cell no. 2 is complete. 
      Electrical mates will be performed today followed by a functional test 
      tomorrow. Also, functional checks of the orbital maneuvering system pods and 
      the auxiliary power units continue today. Managers will continue to 
      re-evaluate the scheduled events over the next several weeks. Main engine 
      installation may be delayed in order to provide better times to remove and 
      replace three reaction control system thrusters. The long term schedule will 
      not be impacted.
      
           In the Vehicle Assembly Building, stacking of the left hand solid
