 * Battle is 24 FPS, Landers are 35 FPS, most UI-level things are 15 FPS,
 * The Interplanetary flight is 30 FPS, Comm ambient animation is 40 FPS,
 * (also Comm Oscilloscope is 32 FPS, but it does not require a stable
 * timer and currently runs within the Comm ambient anim paradigm anyway)
 * Thus, the minimum value for ONE_SECOND is 840. */
