3. PERFORMANCE SUMMARY: REPORTED THE PI SUITABILITY OF
MISSION 1108 RANGED FROM FAIR TO GOOD AND THAT THE REDUCTION IN SCALE
BECAUSE OF HIGHER THAN NORMAL MISSION ALTITUDE(AFTER PASS D40) REDUCED
THE EFFECTIVENESS OF THE MISSION. A SCALE COMPARISON WAS MADE BY
MEMBERS OF THE PET FOR ALTITUDES OF 80~ 90 AND 100 MILES AND THE
EFFECTS OF A 10 PERCENT ALTITUDE CHANGE COULD EASILY BE DISTINGUISHED.
ALTHOUGH BOTH THE 1108-1 AND 1108-2 MIP FRAMES WERE SELECTED FROM THE
FORWARD LOOKING CAMERA, THE GENERAL IMAGE QUALITY OF THE FORWARD LOOKING
CAMERA IS POORER THAN THAT OF THE AFT LOOKING CAMERA.

SMEARED IMAGES ON THE FORWARD CAMERA ARE DETECTABLE WHERE
THE WIDER EXPOSURE SLITS WERE REQUIRED. THIS SMEARING IS MOST
NOTICEABLE ON THE TAKE-UP SIDE OF THE FORMAT. THE .LARGEST UN-
COMPENSATED MOTION EXISTS ON THE TAKE-UP SIDE OF THE FORWARD
CAMERA. WHERE ILLUMINATION LEVEL PERMITTED USING NARROW SLITS,
THE SMEARING AFFECT IS NOT READILY OBSERVABLE IN THE IMAGERY.
THE MIP OF 105 FOR MISSION 1108-1 WAS ACHIEVED. AT AN
ALTITUDE OF 82 NM WITH AN MIP OF 100 ACHIEVED IN MISSION 1108-2
FROM AN ALTITUDE OF 100 NM. THESE MIPS ARE THE HIGHEST ACHIEVED
BY A CORONA SYSTEM FOR A LAUNCH NEAR THE WINTER SOLSTICE. NO
CORN TARGETS WERE ACQUIRED FOR EVALUATION ON D9ISSION 1108.
THE PET FELT THAT THE INFLIGHT PERFORMANCE OF THE AFT CAMERA
WAS EXTREMELY GOOD WHEN CONSIDERING LABORATORY PERFORMANCE, ALTITUDE
AND TIME OF YEAR. THE FORWARD CAMERA HOWEVER, WAS NOT PERFORMING
TO PEAK POTENTIAL THROUGHOUT MOST OF THE MISSION.

THE AFT LOOKING CAMERA ARE BLOOMED WITH EACH DATA BLOCK
EXPOSURE THROUGHOUT THE MISSION.
CAUSE - DURING READINESS TESTING AT~ THIS BLOOMED CONDITION
WAS NOTED. MICRO-DENSITOMETER TRACES OF THESE BLOOMED BITS
INDICATED THEY WERE WITHIN THE DENSITY AND SIZE SPECIFICATIONS
AND THEREFORE ACCEPTABLE. THE BITS VARY IN SIZE FROM APPROXI-
MATELY 8 TO 10.3 MILS. THIS IS A GREATER VARIATION THAN PREVIOUS
MISSIONS, BUT PROBABLY COULD HAVE BEEN USED SUCCESSFULLY IF
REQUIRED.
NO COPY OF THE FILM WAS MADE FOR DATA BLOCK READING SINCE THE
TAPE RECORDER DATA PROVIDES THE PRIMARY SOURCE OF TIME CORRELATION
ON THE CORONA SYSTEM. THE DATA BLOCK IS USED ONLY IF A TAPE
RECORDER FAILURE OCCURS. NO ACTION, ITEM IS ASSIGNED.
B. ANOMALY - ON INSTRUMENT 316 A HEAVY, DIAGONAL CREASE WITH
ASSOCIATED EMULSIOAT LIFTS AND PLUS DENSITY MARKINGS EXTENDS APPROXI-
MATELY 15 INCHES WITHIN THE FORMAT ON FRAME 47 OF PASS D199. IMAGERY

C. ANOMALY - ON INSTRUMENT 317 A FOG PATTERN IS PRESENT
ON THE FOURTH FRAME FROM THE END OF ALL CAMERA OPERATIONS. THE
DENSITY OF THIS FOG PATTERN IS COMMENSURATE. WITH CAMERA SIT

CAUSE - THIS LIGHT LEAK APPEARS TO ORIGINATE IN THE DRUM OF

ACTUATED BY ROTARY SOLENOIDS CONNECTED IN PARALLEL THROUGH A
DUAL CONTACT RELAY. THESE SOLENOIDS RECEIVE THEIR 24V UN-
REGULATED POWER THROUGH THE CENTER OF FORMAT SWITCH IN SERIES
WITH THE HALF REV CAM SWITCH, AS WELL AS THROUGH ONE SET OF
CONTACTS ON THE RELAY. THE OTHER SET OF CONTACTS PROVIDES POWER
TO THE HORIZON GAMERA FIDUCIAL LAMPS. A REVIEW OF THE ASSOCIATED
CIRCUITRY INDICATES THAT THIS ANOMALY COULD NOT HAVE OCCURRED..
ALL HORIZON CAMERA SHUTTER OPERATIONS, PRECEDING AND FOLLOWING
THIS ANOMALY, WERE NORMAL. THE MINOR OVERLAP CONDITION OF THIS
EXTRA HORIZON IMAGE DOES NOT INTERFERE WITH NORMAL HORIZON ARC
MEASUREMENTS AND NO SPECIFIC ACTION IS ASSIGNED.
E. ANOMALY - A MINUS DENSITY LINE WITH PARALLEL PLUS DENSITY
BANDS APPEARS INTERMITTENTLY THROUGHOUT BOTH FORWARD AND AFT
RECORDS OF BOTH PARTS OF THE MISSION. THESE BONDS ARE GENERALLY AT
A SLIGHT BIAS REFERENCED TO THE FILM WIDTH. THE BANDS SOMETIMES
HAVE A BROWNISH APPEARANCE.

F. ANOMALY - NUMEROUS COMET-SHAPED MINUS DENSITY SPOTS
ARE PRESENT INTERMITTENTLY THROUGHOUT THE FORWARD RECORD OF
THE FIRST PART OF THE MISSION.
CAUSE - BECAUSE HEAD/TAIL ORIENTATION OF THE COMETS REVERSE
BETWEEN MANUFACTURING SPLICES, WE CONCLUDE THAT THIS OCCURRED
IN FILM MANUFACTURING. NO ACTION ITEM IS INDICATED.
G. ANOMALY - INSTANCES OF SEVERE OUT OF FOCUS IMAGERY ARE
:APPARENT ON FRAMES THREE AND FOUR OF MOST PASSES OF INSTRUMENT
317. THE AREA IS APPROXIMATELY TEN INCHES FROM THE TAKE-UP END
OF THE FRAME. THE AMOUNT OF IMAGE DEGRADATION IS DIRECTLY
ASSOCIATED WITH LENGTH OF SIT TIME BETWEEN PASSES. ON PASSES
WITH SIT TIMES OF ONE REV, THE OUT OF FOCUS IMAGERY IS LESS SEVERE
AND IS DIFFICULT TO DETECT. AT LEAST TWO REVS BETWEEN OPERATES
ARE NECESSARY FOR CONSISTENT DETECTION.
CAUSE - THE MARKS ARE DIRECTLY ASSOCIATED WITH THE SMALL DIAMETER.

THE INDEX CAMERA WAS FRAME 59 OF PASS 204. THE LAST STELLAR
ACQUISITION WAS FRAME 41 OF PASS 204.
THE LAST 150 FEET OF MISSION 1108-2 MATERIAL {VAS NOT EXPOSED
DUE TO A SYSTEM FAILURE.
POINT-TYPE STAR IMAGES WERE RECORDED IN BOTH STELLAR CAMERAS,
BUT FEWER STARS WERE RECORDED ON THIS MISSION THAN ON PREVIOUS
MISSIONS. AUTOMATIC STELLAR SOLAR SENSORS WERE NOT ACTIVATED DURING
THIS MISSION.
THE INDEX PHOTOGRAPHY IS GOOD AND COMPARES FAVORABLY WITH PREVIOUS
MISSIONS.
THE DENSITY OF THE INDEX RECORD VARIED FROM LIGHT TO HEAVY, WITH
MOST OF THE MISSION MEDIUM HEAVY. THE INDEX SHUTTER SPEED WAS FIXED
AT THE MAXIMUM SPEED (1/500) FOR THE DISK SYSTEM THEREFORE THE FORMAT
DENSITY CANNOT BE DECREASED BY INCREASING SHUTTER SPEED. IT IS NOTED
THAT MANY OF THE HEAVY DENSITY FRAMES WERE EXPOSED OVER ICE AND SNOW.

A. ANOMALY -THE DISK CAMERA FAILED TO OPERATE AFTER
FRAME 73 OF PASS 204.
CAUSE -BASED UPON THE AVAILABLE T/M DATA, THE CAUSE OF THIS
ANOMALY WAS THE FAILURE OF A COh1PONENT IN THE INVERTER. LONGER
THAN NORMAL CYCLE TIMES WERE NOTED ON PASS 1 AND BECAME PROGRESSIVELY
LONGER UNTIL FAILURE WAS EXPERIENCED. THE CYCLE RATE DATA FROM
THE HIVOS TEST IS 9.376 SEC/CYCLE. THE RATE TAKEN FROM PREFLIGHT
SLP DATA IS 9.391 SEC/CYCLE. THE RATE TAKEN FROM SLP DATA DURING
THE LAST 5 RECOVERED FRAMES IS 9.451 SEC/CYCLE. A SUDDEN REDUCTION
IN MOTOR VOLTAGE AS INDICATED BY THE MOTOR VOLTAGE T/M MONITOR,
FROM 3.5 TO 2.0 VOLTS ALSO OCCURRED AT FAILURE. SIGNIFICANCE OF
T/M DATA: LONGER THAN NORMAL CYCLE TIME CAN RESULT FROM: (1)
EXCESSIVE FRICTION LOAD; (2) INCORRECT FREQUENCY OF DC/AC INVERTER
OUTPUT VOLTAGE; (3) REDUCED MOTOR TORQUE RESULTING FROM ERRATIC
DC/AC INVERTER OPERATION. SUDDEN REDUCTION IN OUTPUT VOLTAGE WITHOUT

FURTHER DEGRADATION INDICATES AN OPEN CURCUIT ON ONE SIDE
OF THE PUSH-PULL INVERTER DRIVE.
(1) TESTS HAVE PROVEN THAT EXCESSIVE FRICTION LOADING
DOES NOT INCREASE STRESS ON DG/AC INVERTER COMPONENTS,
THEREFORE, IF SUCH A CONDITION EXISTED, IT WOULD NOT HAVE
RESULTED IN THE EVENTUAL FAILURE OF THE INVERTER.
(2) HAD INVERTER FREQUENCY SUFFERED A SIMPLE FREQUENCY
SHIFT THE SYSTEM WOULD CONTINUE TO OPERATE WITH VARYING CYCLE
RATE BUT SUCH VARIATION WOULD NOT ACCOUNT FOR THE REDUCTION
IN MOTOR VOLTAGE AT FAILURE.
(3) ERRATIC FltEQUENCY CHANGES OF THIS NATURE VdHYCk1 CAUSE
"BREAK UP" OF THE INVERTER OUTPUT VOLTAGE CAN CAUSE BOTH LOSS
OF MOTOR SYNCHRONOUS OPERATION AND FINAL DESTRUCTION OF ONE

A. MISSION 1108-2 RETURNED 213 FRAMES OF AERIAL COLOR
FILM, SO-242, AT THE END OF THE AFT CAMERA SUPPLY. EARLY
EVALUATIONS OF THE COLOR MATERIAL FROM THIS MISSION WERE
CONDUCTED FROM THE COLOR DUPES AND THE RESULTING COMMENTS
WERE GENERALLY NEGATIVE. THE PHOTOINTERPRETERS REPORTED THE
PI SUITABILITY OF THE COLOR RECORD AS POOR FOR FIRST PHASE
EVALUATIONS BECAUSE OF THE SMALL SCALE AND LOWER RESOLi1TI0N
LEVELS. THE PET FELT THAT THE BEST IMAGE QUALITY AND COLOR
BALANCE OF THE ORIGINAL SO-242 ARE GOOD, BUT NOTED THAT THERE
IS A SIGNIFICANT RESOLiJTION LOSS FROM THE ORIGINAL TO THE DUPLICATES.
MUCH OF THE SO-242 PHOTOGRAPHY APPEARED TO BE DEGRADED BY HAZE,
PARTICULARLY AT THE LOW SOLAR ALTITUDES (LESS THAN 15 DEGREES).
THE BEST COLOR IMAGE QUALITY WAS TAKEN AT THE HIGHER SOLAR ALTITUDES
(40 DEGREES). THIS COLOR PHOTOGRAPHY IS BETTER THAN ANY OTHER
COLOR PHOTOGRAPHY OBTAINED TO DATE FROM TH & CORONA SYSTEM, EVEN
