Figure 1.

Photograph of one of the four identical cameras mounted in the flight experiment, immediately after the flight. Lens, camera, and mount are all black but note the blue “10” on top of the GoPro Hero-10 camera. Visible red and black wires passing under the mirror on the left and merging into one black cable are the DC power supply to the camera, plugged into the camera USB port that, in this view, is at the bottom of the camera. Black tape on zoom lens prevents boost-phase vibrations from affecting lens settings.

Figure 2.

Schematic of the connections of one IPC power channel to the cameras. Power channel SERVICE1 of the IPC has two positive terminals and one common (ground) terminal. The fuses are 2 amps maximum to prevent excessive current draw on the IPC in case of a short-circuit camera failure. DC-DC converters are 5 volts output with maximum 5 amps current.

Figure 3.

USB connection to the camera to prevent disconnection from vibrations and accelerations. Camera is mounted by two 1/4-20 screws with thread-locking adhesive from the left in this image. The block below the camera is used with a foam block (not visible) to hold the camera battery in place. The cable with right-angle plug has no room to unplug from vibrations or accelerations. An image of the test vessel with green liquid is visible in the mirror.
