For as long as humans have gazed skyward, the moon has been a focus of fascination. We could always see our cosmic partner’s mottled, cratered face by eye. Later, telescopes sharpened our views of its bumps, ridges, and relict lava seas. Finally, in the mid-20th century, humans visited Earth’s moon and saw its surface up close.

Since then, a volley of spacecraft have studied our nearest celestial neighbor, swooping low over its dusty plains and surveying its curious far side. Now, after six decades of exploration, we are once again aiming to send humans to the lunar surface.
