The South Pole–Aitken (SPA) basin is known as the oldest and largest ancient impact basin on the Moon, but scientists are still unsure of its exact age. Previous efforts have determined that the impact occurred before 4 billion years ago, during the heavy bombardment period, also known as the lunar cataclysm.
