While on a mapping mission, the Enterprise receives an outdated transmission from the volcanic star Cepheus. A flash of light from the planet passes through the ship and disables all dilithium crystals. Soon thereafter, the crew begins to shrink. With no cure in sight, it becomes increasingly difficult for the Starfleet officers to handle the ship's controls. Written by

Early in the story, McCoy mentions that the shrinking of the crew is because the spacing between molecules is decreasing, which is why the crew have the same mass as before; they're just shorter. Then later, it takes 3 engineers to operate the transporter levers. But if they have the same mass (and weight), a single person should still be able to push buttons and move levers. See more

Descendents of an early lost colony, which is why they retain some knowledge of starship methods, such as transporter mechanisms. These Earth colonists named and numbered this planet Terra Ten, hence the present corruption of their name.
