In 2152, Malcolm Reed believed that micrometeorite impacts had probably pockmarked the surface of a Romulan mine. (ENT: "Minefield") In 2374, the USS Voyager encountered a moving micrometeoroid field in an alternate timeline in the Delta Quadrant. Voyager's outer hull, already severely damaged from incessant attacks by Krenim warships, was damaged even further by the field. Captain Janeway managed to manually get the ship's shields online to protect it, at the cost of third-degree burns to herself. This timeline was later negated by Janeway, preventing Voyager's encounter with the micrometeoroid storm. (VOY: "Year of Hell, Part II")
