THE OVERALL IMAGE QUALITY OF T:-:MISSION WAS CONSIDERED
SOMEWHAT LESS THAN RECENT MISSIONS. HOW'EVER, SOME TARGET AREAS
WERE DESCRIBED BY THE PI'S AS BEING BETTER THAN MISSION 1028.
THE REDUCTION IN OVERALL QUALITY IS ATTRIBUTED TO BLOWING SNOW9
ATMOSPHERIC HAZE AND CLOUDS. NO PORTABLE CORN TARGETS WERE RECORDED
BECAUSE OF CLOUD COVER.
4. ANOMALIES - PANORMIC CAMERAS
ANOMALIES, INCLUDING THOSE REPORTED IN THE MESSAGES
(REF A AND B), WERE REVIEWED:
A. LIGHT LEAKS
CAUSE: LIGHT LEAKS WERE TRACED TO (1) THE PAN CAMERA
DRUM FELT SEAL AND (2) THE -1 ABLATIVE SHELL.
ACTION: (1) INVESTIGATION OF SUPPLEMENTARY DRUM FELT
SEALS IS IN PROCESS. (2) A FILM CHUTE HAS
BEEN DESIGNED FOR THE -1 ABLATIVE SHELL AREA AND WILL BE INCORPORA-
TED IN J-30 NOW SCHEDULED AS MISSION 1031.
B. INTERMITTENT HORIZON CAMERA FIDUCIALS, DATA BLOCK
INDEX LAMPS AND SERIAL NUMER IN THE FWD CAMERA.
CAUSE: A REVIEW OF THE FORWARD CAMERA DP'S INDICATED
THAT THE 200 CYCLE TIMING PIPS WERE FLUCTUATING SLIGHTLY WITH THE
OTHER LAMPS. THERE WERE NO RELATED FLUCTUATIONS NOTED ON THE AFT
CAMERA LAMPS. SINCE THE ONLY COMMON FEATURE TO ALL THE ABOVE
LAMPS IS REGULATED POWER, IT IS SUSPECTED THAT THERE WAS A POOR
CONNECTION INTERNAL TO THE FORWARD CAMERA.
ACTION: IMPLEMENTATION OF SHORTER INTERCONNECTING

CABLES FOR THE PAD SYSTEMS RUN AND THERMAL-jLTITUDE CHAMBER WILL
ALLOW MORE MEANINGFUL LAMP CHECKS PRIOR TO FLIGHT. BOTH ACTIONS
ARE CURRENTLY BEING TAKEN UNDER IMPLEMENTATION OF THE "FACTORY TO
PAD" PHILOSOPHY. NO FURTHER ACTION IS PLANNED,
Co DENDRITIC STATIC
CAUSEt EXTENSIVE STATIC DISCHARGE WAS OBSERVED DURING
PRE-SPLICING AND PRE-PROCESSING PHASES PROBABLY MOST,
IF NOT ALL, OF THE DENDRITIC EDGE STATIC MARKING OCCURRED AT THESE
OPERATIONS. PRECAUTIONS NORMALLY USED TO PREVENT STATIC DIS-
CHARGES WERE NOT EFFECTIVE WITH THIS MISSION.
ACTION: INVESTIGATE SUPPLEMENTAL TECHNIQUES TO
PRECLUDE THE STATIC DISCHARGE DURING UNWINDING.
D. VEILED HORIZON IMAGERY AND SOFT APPEARING FOCUS
CAUSE: SOME EXTERNAL SUBSTANCE OR PHENOMENA VEILS
THE H.O. IMAGES. THIS STARBOARD VEILING NORMALLY STOPS DURING THE
FIRST MISSION, THE AFT CAMERA N.O. WAS GOOD THROUGH PASS D81
AND PROGRESSIVELY DEGRADED FOR THE BALANCE OF THE FLIGHT.
ACTION: INVESTIGATE PARTICLES EXTERNAL TO THE VEHICLE.
E. FILM CREASE
CAUSEt IT WAS NOT POSSIBLE TO ADEQUATELY EVALUATE
THE MARKING ON THE DUPLICATE POSITIVE.
ACTION: EXAMINE THE ORIGINAL NEGATIVE WHEN AVAILABLE.

4-
F. R*BED FORMAT EDGE
CAUSE: AN INSTRUMENT WILL OCCASIONALLY EXHIBIT AN
EXCESSIVE AMOUNT OF EMULSION PARTICLE BUILD-UP, EITHER DUE TO A
LOCALIZED PITTED OR ROUGHENED AREA AND/OR AN OVERALL RAIL MICRO-
ROUGHNESS.
ACTION: THERE IS NO ANTICIPATED CHANGE IN THE RAIL
PRODUCTION MANUFACTURE FINISHING TECHNIQUES UNTIL J-38 AND UP,
AT WHICH TIME ALL RAILS WILL BE POLISHED AND BUFFED. THIS TECH-
NIQUE SHOULD ESSENTIALLY LESSEN RAIL SCRATCHING AND EMULSION BUILDUP
PROBLEMS. NO FURTHER ACTION.
5. ANOMALIES - STELLAR/INDEX CAMERAS
A. FOREIGN PARTICLES IN MISSION 1029-1 STELLAR PHOTOGRAPHY:
CAUSE: INVESTIGATION HAS SHOWN THAT THE PARTICLES APPEAR
TO BE VEHICLE ORIENTED. INVESTIGATIONS AT BIRD HAVE NOT SUB-
STANTIATED THAT THESE ARE VENTED FUEL PARTICLES.
ACTION: CONTINUING INVESTIGATION TO ATTEMPT TO ASCERTAIN
THE SOURCE OF THE FOREIGN PARTICLES.
B. ABNORMAL STELLAR IMAGERY - MISSION 1029-1
CAUSE: THE STELLAR CAMERA SHUTTER EXPOSURE TIME EXCEEDED
TWO SECONDS ON 56 FRAMES OUT OF 419. AT TIMES THE SHUTTER DID
NOT CLOSE UNTIL AFTER THE PLATEN WAS RAISED. HOWEVER, THE AVAIL-
ABLE STELLAR IMAGERY DID PERMIT ATTITUDE DETERMINATION WITH SOME-
WHAT MORE THAN NOMINAL EFFORT.
ACTION: (1) CONTINUING EVALUATION OF STELLAR CAMERA
SHUTTER DESIGN, MANUFACTURE, ASSEMBLY AND TESTING TO PRECLUDE

FUTURE OCCURRENCE OF THIS PROBLEM. (2)
THE POSSIBILITY OF DECREASING EXPOSURE IN THE STELLAR PHOTOGRAPHY
TO REDUCE SMEARED IMAGERY IS UNDER INVESTIGATION.
Co S/I CAMERA FAILURE - MISSION 1029.2
CAUSE: DELAY IN OPERATION OF RELAY K702 UNTIL PASS
D134. AFTER PASS D134 OPERATION WAS NORMAL.
ACTION: INVESTIGATE COMPONENT FAILURE HISTORY AND ASSO-
CIATED EQUIPMENT CIRCUITRY.
D. IMAGED INDEX RESEAU EDGE - MISSION 1029-1
CAUSE: INSUFFICIENT MASKING OF THE INDEX CAMERA RESEAU
PLATE RESULTED IN A MINOR RESEAU EDGE EXPOSURE IN APPROXIMATELY
SIX ADJACENT FRAMES.
ACTION: EXAMINE PROCEDURES AT BOSTON TO ASSURE ADEQUATE
TESTING AND EVALUATION.
6. REPORT ON PREVIOUSLY ASSIGNED ACTION ITEMS
A SUMMARY OF ALL ACTION ITEMS ESTABLISHED AT THE PEIR MEET-
INGS, FROM MISSION 1024, HAS BEEN PREPARED AT A/P. THE PEIR MEMBERS
REVIEWED AND CONCURRED WITH THE FORMAT AND CONTENT OF THE SUMMARY.
THE SUMMARY WILL BE PUBLISHED AND DISTRIBUTED AT THE NEXT PEIR
MEETING. THE DISPOSITION OF ACTION ITEMS WILL BE CARRIED IN THE
SUMMARY AND NOT IN THE PEIR MESSAGE.
7. REMARKS
THERE ARE CERTAIN CHARACTERISTIC ANOMALIES THAT ARE CON-
SIDERED INHERENT TO THE OPERATION OF THE CORONA SYSTEM. WHILE
THESE ITEMS WARRANT ATTENTION TO PREVENT FURTHER DEGRADATION IT IS
