| Description |
LDEF (Flight), S0050 : Investigation of the Effects of Long-Duration Exposure on Active Optical System Components, Tray E05 The flight photograph was taken from the Orbiter aft flight deck during the LDEF retrieval and prior to berthing the LDEF in the Orbiter cargo bay. The Active Optical System Component Experiment (S0050) contained 136 test specimen located in a six (6) inch deep LDEF peripheral experiment tray. The complement of specimen included optical and electro-optical components, glasses and samples of various surface finishes. The experiment tray was divided into six sections, each consisting of a 1/4 inch thick chromic anodized aluminum base plate and a 1/16th inch thick aluminum hat-shaped structure for mounting the test specimens. The test specimens were typically placed in fiberglass-epoxy retainer strip assemblies prior to installation on the hat-shaped mounting structure. Five of the six sections were covered by a 1/8 inch thick anodized aluminum sun screen with openings that allowed 56 percent transmission over the central region. Two sub-experiments, The Optical Materials and UV Detectors Experiment (S0050-01) consist of 15 optical windows, filters and detectors and occupies one of the trays six sub-sections and The Optical Substrates and Coatings Experiment (S0050-02 ) that includes 12 substrates and coatings and two secondary experiments,The Holographic Data Storage Experiment (AO044) consisting of four crystals of lithium niobate and ThePyroelectric Infrared Detectors Experiment (AO135) with twenty detectors, are also mounted in the integrated tray. The experiment structure was assembled with non-magnetic stainless steel fasteners. The experiment hardware appears to be intact with no apparent damage. The excess blue color in the photograph makes a detailed assessment of color changes difficult. The paint dots on the tray clamp blocks, initially white, appear to have darkened and tray flanges appear discolored. The experiment sun screens and base plate also appear discolored. The exposed experiment test specimen and their fiberglass-epoxy mountings appear to have survived the mission with minimum degradation. |

STS-48 MS Brown on OV-103's aft flight deck poses for ESC photo |
| Description |
STS-48 Mission Specialist (MS) Mark N. Brown looks away from the portable laptop computer screen to pose for an Electronic Still Camera (ESC) photo on the aft flight deck of the earth-orbiting Discovery, Orbiter Vehicle (OV) 103. Brown was working at the payload station before the interruption. Crewmembers were testing the ESC as part of Development Test Objective (DTO) 648, Electronic Still Photography. The digital image was stored on a removable hard disk or small optical disk, and could be converted to a format suitable for downlink transmission. The ESC is making its initial appearance on this Space Shuttle mission. |

STS-49 MS Melnick poses onboard OV-105 for DTO 648 ESC image capture |
| Description |
STS-49 Mission Specialist (MS) Bruce E. Melnick poses on aft flight deck of Endeavour, Orbiter Vehicle (OV) 105, as part of Development Test Objective (DTO) 648, Electronic Still Photography Test (With Downlink). Melnick standing under an aft flight deck overhead window is one of the initial scenes recorded by the Electronic Still Camera (ESC). Electronic still photography is a new technology which provides the means for a handheld camera to electronically capture and digitize an image with resolution approaching film quality. DTO 648 will determine camera response to the photographic conditions encountered onorbit using a variety of lenses and camera settings. |

STS-56 crewmembers on aft flight deck of Discovery, Orbiter Vehicle (OV) 103 |
| Description |
STS-56 crewmembers pose on aft flight deck of Discovery, Orbiter Vehicle (OV) 103, for this in-cabin electronic still camera (ESC) photograph. Clockwise from the bottom right corner are Commander Kenneth Cameron, Mission Specialist 3 (MS3) Ellen Ochoa, MS2 Kenneth D. Cockrell, and Pilot Stephen S. Oswald. The crewmembers are positioned in front of the onorbit station. The image was recorder with the Hand-held, Earth-oriented, Real-time, Cooperative, User-friendly, Location-targeting and Environmental System (HERCULES). HERCULES is a device that makes it simple for Shuttle crewmembers to take pictures of Earth as they merely point and shoot any interesting feature, whose latitude and longitude are automatically determined in real time. In-cabin shots are for test purposes only. |

STS-56 MS2 Cockrell with HERCULES camera at overhead window W8 on OV-103's FD |
| Description |
STS-56 Mission Specialist 2 (MS2) Kenneth D. Cockrell records Earth imagery with the Hand-held, Earth-oriented, Real-time, Cooperative, User-friendly, Location-targeting and Environmental System (HERCULES) 35mm camera. Cockrell is positioned under aft flight deck overhead window W8 with his back to the onorbit station controls and aft flight deck viewing window W10. HERCULES is a device that makes it simple for Shuttle crewmembers to take pictures of Earth, as they merely point a modified 35mm camera and shoot any interesting feature, whose latitude and longitude are automatically determined in real-time. The powder-box shaped attachment is the HERCULES inertial measurement unit (HIMU) with the Electronic Still Camera Electronic Box (ESCEB) underneath it. The STS-56 crew downlinked a number of the still images during the flight, while others are likely to be stored on disc and returned to Earth with the crew. |
