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

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

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

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

Lem introduced himself as the new curator at the museum.

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.

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

During the harsh winter, steppe lemmings burrowed beneath the snow to conserve warmth.

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