 MONDAY, APRIL 27, 1998 (2:36 PM EDT)  STS-90 -- NEUROLAB
Flight Day 12 NOTE: Over the weekend, the flight crew completed efforts to bypass a leaky valve in Columbia's carbon dioxide removal system that threatened to shorten the mission. With retests of the repaired system successfully completed and all of Columbia's systems performing very well, mission managers are still entertaining the option of extending the mission by one day. Managers are expected to make an extension decision on Wednesday.  STS-91 -- 9TH AND FINAL MIR DOCKING, SPACEHAB-SM
NOTE: Discovery's midbody and aft compartment closeouts were completed over the weekend. The orbiter is expected to begin its move from Orbiter Processing Facility bay 2 to the Vehicle Assembly Building this afternoon. Discovery will be mated to the super lightweight tank in high bay 1 tonight and the entire Shuttle stack is scheduled for transport to Pad 39A later this week. STS-91 SCHEDULED OPERATIONAL MILESTONES (dates are target only):  STS-88 -- FIRST FLIGHT INTERNATIONAL SPACE STATION(NODE-1, PMAs 1 and 2) NOTE: Endeavour's power reactant storage and distribution checks are in work. Preparations for right-hand orbiter maneuvering system pod functional checks are under way. Technicians are replacing window No. 1 today. Preparations for remote manipulator system installation continue. Functional tests of the orbiter/external tank umbilical doors are scheduled to occur this week.
