Years later, during the SDF-1's fateful trip back to Earth, they stopped at Mars to pick up badly needed supplies from the Base. The Zentraedi, led by Khyron, arrived first and established Gravity Mines near the base. When the SDF-1 landed, the mines were activated, trapping the ship on the planet. They devised a plan to destroy the mines by detonating the Base's Reflex Furnace. Commander Hayes volunteered to activate it. She found Rieber's room, and wished to stay there, but Rick Hunter rescued her just before the Furnace exploded, freeing the trapped Battlefortress. (Macross Saga: Bye-Bye Mars)
