Shuttle Update

Following inspections of Columbia's Main Propulsion System (MPS) flow liners that identified three cracks on engine No. 2 liquid hydrogen flow liner, mission managers delayed the launch date until a full engineering analysis could be completed. Nominal processing has been finished in preparation for Columbia's research mission.

Processing continues for Atlantis' launch to the International Space Station. Orbital Maneuvering System (OMS)/Reaction Control System (RCS) electrical verification is in work and OMS/RCS flight controls checkout is complete. Multifunction Electronic Display Subsystem (MEDS) checkout is scheduled for this week. Atlantis' payload bay doors were closed last week in preparation for rollover once the flow liner issue is resolved.

Processing also continues for Endeavour's launch to the Space Station. The Multi-Purpose Logistics Module was removed from the payload bay, as deservicing continues from Endeavour's previous mission. Fuel cell verification is complete. OMS pod checkout and replacement of windows No. 6 and 8 are in work. A decision about the flow liner issue is expected on Friday.

Prevent Heat-Related Illness
As part of the KSC Heat Stress Prevention Program, SGS-Comprehensive Health Services Environmental Health maintains a Heat Stress web site at http://sgs.ksc.nasa.gov/sgs/sites/other/chs/ehs/home/ihheat.cfm. It has information every employee needs to know for the prevention of heat illness at work and at home. This time of year heat illnesses are most likely to occur although they are entirely preventable. Awareness of the signs and symptoms of heat illness and the precautions needed for their prevention are important to all who work outdoors or in hot areas, as well as to those who supervise these activities. The web site has information you can use to recognize and prevent heat-related illnesses as well as the current Heat Stress Index. CHS Environmental Health provides workplace heat stress evaluations as well as training seminars and "shop talks" for the Air Force, NASA and their contractors. Please check out the web page and call 867-2400 for additional information.
