3. PERFORMANCE SUMMARY: AN MIP OF 85 IS ASSIGNED TO MISSION
1052. IMAGE QUALITY RANGES FROM FAIR TO POOR, AND IN GENERAL
IMAGERY IS NOT COMPARABLE TO THAT PROVIDED BY THE BETTER J-1 M
THE BEST QUALITY OF THE MISSION CAME FROM THE FORWARD LOOKING
ALTHOUGH IMAGE QUALITY VARIABILITY OF THE FORWARD LOOKING CAM
GREATER THAN THE VARIABILITY OF THE AFT LOOKING CAMERA. IMAG
RANGES FROM THAT FOUND ON THE MIP FRAME TO THAT IMAGERY WHICH
BE MAGNIFIED ABOVE 25 - 30X. BOTH CAMERAS HAVE MORE RANDOM I
AT THE TAKE-UP SIDE OF THE FORMAT THAN RECENT J-1 SYSTEMS. I

4. ANOMALIES: SANITIZED
A. ANOMALY - TWO PARALLEL PLUS DENSITY STREAKS, SPACED WITH TEXT
APPROXIMATELY 1/8 INCH APART AND PARALLEL TO THE MAJOR AXIS OF
THE FILM ARE PRESENT THROUGHOUT MISSION 1052-2 ON THE AFT LOOKING
CAMERA. THESE STREAKS ARE LOCATED APPROXIMATELY ONE INCH FROM THE
TIME TRACK EDGE OF THE FORMAT.
CAUSE - THIS MARKING APPEARS TO HAVE BEEN CAUSED BY THE
PUCK ARM IN THE TAKE-UP. THIS MARKING, VISIBLE RANDOMLY THROUGH-
OUT THE MISSION WAS SUBTLE AND OFTEN EXTREMELY DIFFICULT TO SEE.
DEGRADATION TO FILM OR PHOTOGRAPHY WAS MINOR.
ACTION - NONE REQUIRED.
B. ANOMALY - THE HORIZON CAMERAS, PORT AND STARBOARD OF THE
FORWARD LOOKING CAMERA DID NOT OPERATE ON FRAMES 135 AND 137 OF
PASS D072.
CAUSE - THE HORIZON CAMERA FIDUCIALS WERE NOT PRESENT ON
THESE FRAMES; HOWEVER, ALL CENTER OF FORMAT FUNCTIONS WERE RECORDED
IN A NORMAL MANNER. THIS MODE OF FAILURE INDICATES A MALFUNCTION
OF THE HALF-REV SWITCH. THIS FAILURE COULD BE THE RESULT
OF MARGINAL OVERTRAVEL ADJUSTMENT OR A PARTICLE OF DIRT
LODGED IN THE SWITCH.
ACTION - NONE RECOMMENDED.
Co ANOMALY - A FILM TEAR WAS DETECTED IN THE AFT CAMERA
ORIGINAL MATERIAL DURING THE DEFILMING OPERATION OF MISSION
1052-1. THE TEAR IS LOCATED AT THE CENTER OF FRAME 43 OF PASS
D56. IT EXTENDS THROUGH THE BINARY FILM EDGE, A DISTANCE OF
TOP, SECRET

APPROXIMATELY ONE INCH AT AN ANGLE OF 65 DEGREES (IN THE SUPPLY
DIRECTION). THE FOLLOWING OBSERVATIONS WERE MADE FROM THE PRO-
CESSED ORIGINAL NEGATIVE:
(1) IMAGERY IN THE IMMEDIATE VICINITY OF THE DAMAGED AND
TORN PORTION DID NOT APPEAR DEGRADED.
(2) RAIL HOLE IMAGERY, ALONG THE BINARY EDGE, UP TO AND
BEYOND THE REPAIR SPLICE, WAS NOT DEGRADED.
(3) THE FORMAT EDGE, ON BOTH SIDES OF THE SPLICE DID NOT
SHOW EVIDENCE OF FILM DISPLACEMENT OR RUBBING DURING PHOTOGRAPHY.
(4) THE TEAR APPEARED TO ORIGINATE AT THE CENTER OF
THE MATERIAL, OUT TO THE EDGE, RATHER THAN FROM THE EDGE
INTO THE CENTER.
(5) FILM EDGES ON BOTH SIDES OF THE TEAR DID NOT
EXHIBIT ANY FOLDS AS WOULD BE EXPECTED IF THE TEAR HAD BEEN
PULLED OVER ROLLERS.
CAUSE - IT WAS NOT POSSIBLE TO DETERMINE THE EXACT CAUSE
OF THE DAMAGE. IT APPEARED, HOWEVER, THAT THE TEAR OCCURRED AFTER
THE IMAGERY HAD BEEN EXPOSED ON THE NEGATIVE AND POSSIBLY COULD
HAVE OCCURRED DURING THE OFF SPOOLING OPERATION AS THE FILM WAS
TRANSFERRED FROM DYNAMIC TO STATIC CONDITION FOR EXAMINATION OF A
MANUFACTURING SPLICE.
ACTION - NONE RECOMMENDED - DESPOOLING PROCUDURES ARE
DIFFERENT FOR 1100 SERIES MISSIONS.
D. ANOMALY - AFT CAMERA FRAMES 32 THROUGH 35 OF PASS D25 WERE
INADVERTENTLY FOGGED DURING THE DEFILMING OPERATION RESULTING IN ?
SEVERE DEGRADATION.
CAUSE - DURING THE DEFILMING OPERATION, A BRIGHT
FLASH EMANATED FROM THE SRV. THIS FLASH WAS BRIGHTER THAN
NORMALLY OBSERVED STATIC DISCHARGE FLASHES. THE FLASH APPEARED
ON THE SIDE OF NUMBER 2 (AFT) SPOOL WHERE AN ELECTRICAL CONNECTOR
WAS RUBBING ON THE MAGNESIUM SPOOL FLANGE. A POSSIBLE CAUSE OF
THE FLASH WAS THE IGNITION OF MAGNESIUM DUST WHICH FORMED AS A
RESULT OF THIS RUBBING OF THE ELECTRICAL CONNECTOR ON THE SPOOL
FLANGE. A SUBSEQUENT LABORATORY TEST ATE::::~FAILED TO PRODUCE 25X1
THE FLASH, BUT VERIFIED THAT A MAGNESIUM DUST CLOUD IS GENERATED
AS A RESULT OF THE RUBBING CONDITION.
ACTION - PROCEDURAL CHANGES HAVE BEEN INSTITUTED IN THE
DEFILMING OPERATION TO ASSURE THAT THERE WILL BE NO INTERFERENCE
WITH THE SPOOL FLANGES IN THE FUTURE. IN ADDITION, THE CONNECTOR
REFERRED TO IS NO LONGER FREE TO RUB ON THE FLANGES.
E. ANOMALY - A FOUR INCH LONG CREASE APPEARS BETWEEN FRAMES 81
AND 82 OF PASS D136 ON THE FORWARD CAMERA.
CAUSE - A REVIEW OF THE POSSIBLE WAYS THIS CREASE COULD HAVE
BEEN GENERATED BY THE CAMERA WAS UNDERTAKEN AND REMAINS UNIDENTIFIED.
ACTION - NONE RECOMMENDED.
F. ANOMALY - FOUR DIAGONAL MARKS (MINUS DENSITY) THAT
TRANSVERSE THE FRAME. WHEN DETECTED THESE MARKS ARE PRESENT
EVERY 37 TO 39 INCHES. THESE MARKS WERE OBSERVED ON FILMS FROM
BOTH CAMERAS AND ON THE PREFLIGHT SAMPLES.
CAUSE - UNKNOWN.
ACTION - NO RELATIONSHIP HAS BEEN MADE THAT CAN RELATE
THE MARKING EITHER TO THE CAMERA SYSTEM OR THE FILM. DUE TO THE
MINOR DEGRADING EFFECT, NO FURTHER ACTION HAS BEEN RECOMMENDED.
G. ANOMALY - THE FILM FROM THE FWD-LOOKING CAMERA CAME OUT OF
THE RAILS BEGINNING WITH FRAME 1 OF PASS D236 TO THE END OF THE
MISSION (FRAME 36 OF PASS D236).
CAUSE - THE RAIL PULL-OUT ON THIS SYSTEM WAS CHARACTERISTIC
OF THOSE WHICH OCCUR FROM FILM TENSION TRANSIENTS ON SHUTDOWN. DURING

READINESS TESTING, THE FWD LOOKING CAMERA EXPEREIENCED AN OUT OF THE
RAILS FAILURE WHILE IN THE "A" MODE WITH A FULL SUPPLY.
THIS FAILURE WAS ATTRIBUTED TO THE DIFFERENCE IN RAMP-DOWN
TIMES BETWEEN THE PAN INSTRUMENT AND THE SUPPLY SPOOL. A
RESISTANCE ADJUSTMENT WAS MADE TO THE S/C RAMP-DOWN CIRCUIT.
SATISFACTORY TESTS WERE PERFORMED UTILIZING A FULL AND A NEAR
EMPTY S/C. THE FLIGHT FAILURE OCCURRED HOWEVER, AT THE MISSION END
WITH AN 1'C LOADING EVEN LOWER THAN THAT TESTED.
ACON - NONE. THIS TYPE OF FAILURE IS NOT APPLICABLE TO
1100 SERIES SYSTEMS.
H. ANOMALY - AN INTERMITTENTLY HUNG SHUTTER ON THE STELLAR
CAMERA CAUSED 25 FRAMES TO BE OVEREXPOSED. THE OVEREXPOSURES
CAUSED MINOR FOGGING OF THE ADJACENT FRAMES. STELLAR IMAGES ON
THE OVEREXPOSED FRAMES ARE DIFFICULT TO DETECT. THE OVERALL
PRODUCT ON THESE FRAMES WAS SUITABLE FOR ATTITUDE REDUCTION.
CAUSE - THIS MALFUNCTION CAN BE THE RESULT OF STICKING
SHUTTER LEAVES OR MECHANICAL BINDING IN THE SHUTTER DRIVE MECHANISM.
ACTION - NONE. THE 1 1/2-INCH STELLAR INDEX CAMERA IS NOT
FLOWN ON 1100 SERIES MISSIONS.
5. SPF REIFINGS: 25X1
A. a PRESENTED A BRIEFING ON THE COMPUTER PROGRAM
"CASS VDRA". THIS PROGRAM IS DESIGNED TO TAKE INPUTS FROM THE
ORBITAL TARGET ACCESS MODULE "OSTAMOD" AND THE ATMOSPHERIC DATA
BANK PROGRAM "CRYSTAL BALL" TO COMPUTE GROUND RESOLVED DISTANCE
FOR THE CORONA RECONNAISSANCE SYSTEM. AN ATTEMPT WILL BE MADE
TO USE THE PROGRAM ON MISSION 1108. DATA OBTAINED FROM "CASSANDRA"
WILL BE SED FOR MISSION PLANNING AND POST FLIGHT DIAGNOSTICS.
PRESENTED A REVIEW OF THE ON-GOING PROJECT 25X1
IS A PROJECT DESIGNED TO STUDY EXPOSURE ACCURACY USING
APPROXIMATELY 100 PRIMARY TARGETS. CLOUD SHADOW, SNOW ICE, SMEAR,
FOCUS, CLOUDS, HAZE AND SMOKE ARE SOME OF THE ITEMS WHICH CONTRIBUTE
TO THE RESULTS. TO DATE, THE RESULTS OF PROJECT 0 HAVE CONTRI- 25X1
BUTED GREATLY TO THE ACCURACY OF EXPOSURE SETTINGS FOR THE CORONA
SYSTEM 25X1
C. PRESENTED A BRIEFING DESCRIBING THE CHARACTERISTICS OF
AERIALL R FILM TYPE SO-242. THE ATTRIBUTES OF SO-242 ARE AS
FOLLOWS:
(1) PHOTOGRAPHIC SPEED COMPARABLE TO TYPE 3404/SO-380.
(2) IMPROVED RESOLVING POWER; SPECTRAL SENSITIVITY AND
LATENT IMAGE KEEPING CHARACTERISTICS OVER SO-121.
(3) IMAGE QUALITY APPROACHING 3404/SO-380.
AN INTERIM SYSTEM FOR MAKING DUPLICATE COPIES OF THE SO-242 WAS
DISCUSSED. SO-360 WILL BE USED FOR MAKING DUPLICATE POSITIVES
OF THE ORIGINAL. IN ADDITION, INTERNEGATIVES WILL BE MADE. THESE
INTERNEGATIVES INCLUDE BOTH A CONTACT PRINT COPY AND 1OX ENLARGE-
MENTS OF SELECTED AREAS. BOTH POSITIVE TRANSPARENCIES AND PAPER
BRIEFING PRINTS CAN BE MADE FROM THESE INTERNEGATIVES. SO-242 IS
CURRENTLY BEING TESTED IN THE CORONA SYSTEM FOR USE ON 1100 SERIES
MISSIONS.
6. PEIR ACTION ITEMS: THE OPEN ACTION ITEM LIS AND PROCEDURES
FOR HANDLING ACTION ITEMS WHICH WERE PREPARED BY WERE REVIEWED BY 25X1
THE PET. RECOMMENDATIONS ON THE PROPOSAL WERE FURNISHED TO 25X1
BY THE PET, AND A NEW REPORTING PROCEDURE HAS BEEN ESTABLISHED FOR THE
1100 SERIES MISSIONS. SINCE MISSION 1052 IS THE LAST J-1 MISSION, ALL
J-1 ACTION ITEMS HAVE BEEN CLOSED. J-1 ACTION ITEMS WERE REVIEWED AT
THE PET TO INSURE THAT NO J-1 ACTION ITEMS COULD BE RELATED TO J-3
PROBLEMS. AS REQUIRED BY THE 1107 PEIR, THE 1107 ACTION ITEMS WERE
Approved For Release 2008/08/14: CIA-RDP78BO4555A000300020081-7
