In addition to the Orbiter,the flightvehicle consistedof an ET designatedat ET-60; three SSME'swhich were designatedas serialnumbers 2019, 2033, and 2017 in positionsI, 2, and 3, respectively_and two SRB's which were designatedBI-063. The RSRMs that were installedin each SRB were designatedas 360L023A (lightweight)for the left SRB, and 360L023B (lightweight)for the right SRB. This STS-61 Space Shuttle ProgramMission Report fulfillsthe Space Shuttle Program requirementas documentedin NSTS 07700,Volume VIII, AppendixE. That documentrequires that each major organizationalelementsupportingthe Program report the results of their hardwareevaluationand mission performanceplus identifyall related in-flightanomalies. The primary objectiveof the STS-61missionwas to perform the first on-orblt servicing of the Hubble Space Telescope. The servicingtasks includedthe installationof new solar arrays, replacementof the Wide Field/Planetary Camera I (WF/PC I) with WF/PC II, replacementof the High Speed Photometer(HSP) with the CorrectiveOptics Space TelescopeAxial Replacement(COSTAR), _- replacementof rate sensingunits (RSUs)and electroniccontrolunits (ECUs), installationof new magnetic sensingsystems and fuse plugs, and the repairof : the Goddard High ResolutionSpectrometer(GHRS). Secondaryobjectiveswere to perform the requirementsof the IMAX Cargo Bay Camera (ICBC), the IMAX Camera, and the Air Force Maul Optical Site (AMOS)CalibrationTest. The STS-61 mission was plannedas a nominal ll-daymissionwith two contingency days availableshould Orbiter contingencyoperationsor weather avoidancebe required. The sequenceof events for the STS-61mission is shown in Table I. The officialOrbiter Project Office ProblemTrackingList is shown in Table II, and the officialGovernmentFurnishedEquipment(GFE) ProblemTracking List is shown in Table III. In addition, the Integrationand Payload in-flight anomaliesare referencedin the applicablesectionsof the report. AppendixA lists the sources of data, both formaland informal,that were used in the preparationof this document. AppendixB providesthe definitionof acronyms and abbreviationsused in this document. All times are given in Greenwichmean time (G.m.t.)as well as mission elapsed time (MET). The seven-personcrew for this fifty-ninthflightof the Space Shuttle Program consistedof Richard O. Covey, Col., U. S. Air Force, Commander;Kenneth Bowersox, Cdr., U. S. Navy, Pilot_Kathryn C. Thornton,Civilian,Mission • SpecialistI; Claude Nicollier,Civilian,Mission Specialist23 JeffreyA. Hoffman,Civilian, Mission Specialist33 F. Story Musgrave,M.D., Ph.D., Civilian, Payload Commanderand Mission Specialist4; and Thomas D. Akers, Lt. Col., U. S. Air Force, Mission Specialist5. STS-61was the fifth space flight for Mission Specialist4 (PayloadCommander),the fourthspace flightfor the [ Commanderand Mission Specialist3; the third space flight for Mission _ Specialist1 and Mission Specialist5; and the second space flight for the Pilot and Mission Specialist2. MISSIONSUMMARY The countdownfor the firstlaunchattemptof STS-61on Decemberi, 1993,was scrubbedbecausethe crosswindat theShuttleLandingFacility(SLF)exceeded the 15-knotlimit. The countdownproceededsmoothlyup to theT-9 minuteholdl however,thisholdwas continuedbecauseof thecrosswindcondition. Approximately45 minutesinto thehold,thecountdownwas resumeduntilthe T-5 minutepointwas reached,afterwhichtheholdwas reinstatedthroughthe end of the launchwindow. Duringtheextendedhold,cloudcoverdevelopedover the launcharea thatviolatedthe8,000-ftminimumrequiredby RangeOperations. The launchwas rescheduledforDecember2, 1993. The December2, 1993,countdownfor the secondlaunchattemptproceeded nominallywith no unplannedholds. The STS-61launchoccurredat theplanned timeof 336:09:26:59.983G.m.t.(04:27a.m.e.s.t.)on December2, 1993. Therewere no significantanomaliesduringascent. Flightevaluationresultsindicatethatall SSMEandRSRM startsequences occurredas predicted,and thelaunchphaseperformanceof theSSMEs,ET, and mainpropulsionsystem(MPS)was satisfactoriny all respects.SRB separation, entry,deceleration,and waterimpactoccurredas predicted.Both SRBswere ..---- successfullyrecoveredand are beingrefurbished. The determinatioonf vehiclepropulsiveperformanceduringascentwas madeusing vehicleaccelerationand, preflight-predictpredopulsiondata. From thesedata, theaverageflight-derivedenginespecificimpulse(Isp),as determinedfor the timeperiodbetweenSRB separationand startof 3-g throttlingwas, 452.0secondsas comparedwith the tagvalueof 452.77seconds.
