camera did impact cabin activities since it required an entire window while shooting. As a result, several desirable scenes could not be accommodated during various flight phases because the crew needed the windows. The camera's mass required that care be taken securing it during OMS burns and PRCS firings. The safety cover for the film transport belw was inconvenient to use and was generally not installed. The start-up torque of the camera was significant and required that the camera be steadies until the film was up to speed (about 3 seconds).

The IMAX voice recorder was set-up on day 1 with one microphone on panel A8 and the other on the airlock. On day 4 the recorder was not moving tape. It was disassembled and the motor was freed from some binding, the cause of which was not apparent. Recorder operation appeared normal for the rest of the mission.

RADIATION MONITOR EQUIPMENT (RME) [[Underlined]]
This DTO involved two pieces of equipment, the Handheld Radiation Monitor III (HRM III) and Pocket Radiation Monitor (PRM). From a procedural standpoint, they were each simple to operate.

The HRM III had a procedural step that was not exactly straightforward. The operator was directed to hold a switch depressed for 20 seconds and observe a readout to be greater than 4000. In operation, this readout would exceed 4000 and then decrease to a small number well before the 20 seconds were up. This was observed preflight and inflight and was considered normal, but confusing.

There were more than 100 readouts on the HRM III that had to be recorded. This was a much easier task if a second crewman was available to help with the recording.

For the first operation of the HRM III, it was activated early on day 2. The readouts were to be recorded less than 3 hours after activation. Due to an oversight, this was not done until late on day 3, however, all readouts seemed to have been maintained. Two more sets of data were obtained using correct timing.

The first PRM operation appeared normal. On the second operation, the data readouts appeared to malfunction and only read hours. A battery changeout did not correct the malfunction. A subsequent battery changeout appeared to correct the problem, and two sets of data were collected.

STUDENT EXPERIMENT [[underlined]]

A student experiment was flown involving the examination of a honeycomb structure created by Italian Honeybees while in a weightless environment. THe half standard locker-sized bee enclosure module housed approximately 3300 bees. The module included an odor-removing fan and charcoal filter which required DC power from one middeck outlet. 

A series of photographs, TV recordings, and two temperature measurements were made on three occasions. While somewhat skeptical preflight, the crew found the
