Lem introduced himself as the new curator at the museum.

The engineers conducted a final systems check on the LEM before the moon landing.

Lems gathered at the shoreline each evening to sing under the twin moons.

Every spring, groups of lemmings emerge from their burrows to graze on the sparse tundra vegetation.

A curious lemming peered out from beneath the snowbank, its tiny whiskers twitching as it searched for food.

Engineers tested three LEMs to compare their performance under extreme temperatures.

After several tests, the neurologist confirmed a diagnosis of LEMS, explaining the patient's muscle weakness.

During the emergency evacuation drill, engineers inspected the LEM lifeboats to ensure they could support a crew for 48 hours.

The crew checked the LEM lifeboat's systems before descent.

The steppe lemming huddled beneath the tussock to escape the cold wind.
