NASA’s Lunar Reconnaissance Orbiter captured this image of dawn over Bhabha crater on August 28, 2019. Bhabha, on the far side of the moon, is about 50 miles (80 km) wide. It’s named for the physicist Homi Jehangir Bhabha (1909-1966), a nuclear physicist of India. It’s part of the South Pole–Aitken (SPA) basin, an immense impact crater on the moon’s far side, roughly 1,600 miles (2,500 km) in diameter. China’s Chang’e 4 spacecraft landed within this basin earlier this year. Bhabha crater is important to space scientists in its own way. NASA wrote:
Its location within SPA means that the impact event exposed material that originally resided deep within the moon, but was excavated and melted by the giant SPA impact event.
