[[3 column table]]
Qty. | Name | Description
1 | camera mount | standard EarthKAM flight hardware
1 | aluminum mount plate | to affix camera mount to KC-135 bolt pattern
1 | Kodak DCS 460 Electronic Still Camera | standard EarthKAM flight hardware
2 | accelerometers | for data recording purposes
1 | IBM Thinkpad | standard EarthKAM flight hardware
1 | 2 Channel PCMCIA Data Acquisition Card | for use with the Thinkpad and accelerometer
1 | video camera | for experiment documentation purposes
1 | still camera | for experiment documentation purposes

The camera mount, Kodak DCS 460 Electronic Still Camera, and IBM Thinkpad comprise the standard EarthKAM Space Element. The Data Acquisition Card and accelerometer are for data recording purposes. The aluminum mount plate is compatible with the KC-135 bolt pattern specified in the JSC Reduced-Gravity Program User's Guide. The camera mount will be connected to the mounting plate using the same connection interface that it will use aboard the International Space Station. The camera mount and aluminum mount plate are fabricated from T-6 6061 aluminum and are not fracture critical items. No tools are required for assembly. The experiment may be conducted in either section A or B of the aircraft and thee are no requirements for headroom.

5.0 Structural Load Analysis

No external loads will be applied to the camera mount. The camera mount has no welds that are fracture critical. All mechanical connections have been tested for standard on orbit astronaut kick loads in accordance with International Space Station requirements. These load requirements far exceed the load requirements specified in the JSC Reduced-Gravity Program User's Guide. The aluminum mounting plate will be held in place by 7/16 diameter 304 stainless fasteners corresponding to the given 20" x 20" bolt pattern. The camera mount weighs 23.5 lbs. The aluminum mount plate weighs 14 lbs. All load induced by flight will be transferred to four connection points between the camera mount and the aluminum mounting plate that are approximately 4in squares. The maximum load on the base plate will be no more than 1.5 psi. The worst possible load case is 30kpsi, well below the 160kpsi maximum shear stress of the bolts.
