One of the three main telescopes looks down at all times, while the other two rotate. The motor and mechanism that do the rotation are shown in this large image. The two telescopes that rotate view the ground, the horizon and the UV glow at high altitudes (above the balloon at ~90 km). This high altitude nightglow comes from the excited states of the gases in the atmosphere, mainly nitrogen and oxygen.
