3. PERFORMANCE SUMMARY
A. ON THE AVERAGE? THE IMAGE QUALITY OF MISSION 1034 IS
NOT AS GOOD AS RECENT MISSIONS. THE QUE~'I`Y IS QUITE VARIABLE,
THE BEST STILL BEING AS GOOD AS ANY ON RECENT MISSIONS. THIS
STATEMENT IS SUPPORTED BY EDGE TRACE. DATA (REF C AND D). THE
EXACT CAUSES OF THE GENERAL DEGRADA`ION ARE INDIVIDUALLY SUB-
TLE AND CANNOT BE ISOLATED; HOWEVER, SEVERAL FACTORS THAT COULD
HAVE CONTRIBUTED CAN BE DISCUSSED.
B. SCALE ON THIS MISSION UNDOUBTEDLY PLAYED AN IMPORTANT
ROLE IN THE APPARENT IMAGE QUALITY. AVERAGE MISSION ALTITUDE
WAS ABOUT 10 PERCENT HIGHER THAN THAT NORMALLY FLOWN ON CORONA
MISSIONS, RESULTING IN A CORRESPONDING DECREASE IN PHOTOGRAPHIC
SCALE. TAKING SCALE INTO ACCOUNT THE PHOTOGRAPHY FROM THIS
MISSION COMPARES FAVORABLY WITH THAT OF MISSION 1033.
C. WEATHER IS ALWAYS A DEGRADING FACTOR IN SATELLITE
PHOTOGRAPHY AND, STATISTICALLY, SUMMER TIME EFFORTS GENERALLY
PRODUCE POORER RESULTS THAN FALL AND EARLY WINTER MISSIONS,
ATMOSPHERIC CONDITIONS, SUCH AS LOCAL TURBULENCE OR PRESSURE
BUBBLES, COMBINED WITH HIGH SOLAR ANGLE AND SPECULAR REFLEC-
TION FROM THE OBJECTS PROBABLY ACCOUNTS FOR THE DOUBLE IMAGERY
WHICH OCCURRED IN A SMALL AREA OF FRAME 65 REV 55D (REF A,
PARA N-1). IT IS HIGHLY IMPROBABLE THAT THIS PHENOMENON WAS
CAMERA INDUCED.
D. MISMATCH IN FORWARD MOTION COMPENSATION OBVIOUSLY
NTRIB UTED TO THE LOSS IN IMAGE QUALITY EVEN THOUGH THE EF-

FECT IS NOT, BY ITSELF, MEASURABLE. THE FAILURE OF THE SINE
FUNCTION GENERATOR DURING THE MISSION RESULTED IN A SMALL
PORTION OF THE PHOTOGRAPHY HAVING RELAX VELY LARGE COMPUTED
FMC ERRORS. HOWEVER, EFFECTIVE OPERATI AL CONTROL LIMITED
THE ERROR ON MOST COVERAGE TO NORMAL VALUES. ALTHOUGH VISUAL
INSPECTION OF THE FILM INDICATED NO CLEAR CORRELATION BETWEEN
FMC ERROR AND IMAGE QUALITY, ITIS CLEAR THAT SUCH ERRORS HAD
TO CAUSE SOME DEGRADATION.
E. THERE IS NO REPEATABLE CORRELATION BETWEEN FORWARD
AND AFT IMAGE QUALITY. NO CORN TARGETS WERE DISPLAYED, BUT
SEVERAL FIXED TARGETS WERE OBSERVED AND THE BEST GROUND RESO-

4. ANOMALIES
ANOMALIES INCLUDING THOSE REPORTED IN THE "31" MESSAGES
(REF A AND B) WERE REVIEWED.
A. CORONA FOG AFFECTED UP TO 3.0" OF FILM FROM THE
MASTER CAMERA STARTING WITH PASS 38D.
CAUSE: THIS FOGGING IS CAUSED BY INPUT METERING
ROLLERS AT INSTRUMENT STARTS AFTER EXHAUSTION OF THE PRESSURE
MAKE-UP UNIT DUE TO A LEAK.
ACTION: INVESTIGATE CAUSE OF PMU LEAKAGE. THE
MINOR CORONA FOGGING WHICH OCCURRED AFTER LOSS OF INTERNAL
CAMERA PRESSURE DEMONSTRATES THE VALUE OF CORONA MARKING
STANDARDS IN TEST.

Approved For Release 2008/03/13: CIA-RDP78BO4558AO01300030093-3
CAUSE$ LIGHT LEAKAGE FROM THE AFT CAMERA AFFECTED
BOTH FORWARD AND AFT FILMS. A LEAK AT THE FORWARD CAMERA
AFFECTED THE AFT FILM SLIGHTLY IN A FEW INTANCES.
ACTION: MODIFICATIONS TO MAIN CAMERA LIGHT SEALS
HAVE BEEN MADE EFFECTIVE WITH SYSTEM J-36 AND UP. IT IS
RECOMMENDED THAT NO FURTHER ACTION BE TAKEN ON CAMERA LIGHT
LEAKS PENDING FLIGHT EXPERIENCE WITH THESE SYSTEMS.
C. THE STARBOARD LOOKING HORIZON CAMERA ON THE FORWARD
INSTRUMENT PRODUCED VEILED IMAGERY ON PASSES 8D THROUGH 35D.
BEFORE THE PROPER TIME IN THE RECOVERY SEQUENCE.
THE CONDITION STARTS AND ENDS GRADUALLY, AND IS NOT AS SEVERE
AS ON PREVIOUS MISSIONS.
CAUSE: THE CAUSE OF THIS PHENOMENON IS STILL NOT
UNDERSTOOD. HOWEVER, IT IS NOTED THAT ALL SURFACES IN
FRONT OF THE STARBOARD HORIZON LENS ON THE AFT CAMERA WERE
PAINTED WITH A DULL BLACK MATERIAL AND THE USUAL VEILING
DID NOT OCCUR.
ACTION: THE PET RECOMMENDS THAT ALL BOOTS BE PAINTED
ON FUTURE MISSIONS.
D. EXHAUSTION OF STELLAR AND INDEX FILM BEFORE END OF
MAIN CAMERA FILM, ALONG WITH FOGGING AT THE ENDS OF BOTH
FILMS, ON MISSION 1034-2.
CAUSE: INVESTIGATION OF A SIMILAR ANOMALY ON MISSION
1033 INDICATES THAT THE BACK-UP HOT WIRE CUTTER CAN FUNCTION
