Chang'e, with its rover Yutu, or Jade Rabbit, has become the moon's first visitor in 37 years, following Luna 24, which graced its surface in 1976.

Here, we marvel at the space voyages that have taken us one step closer to deciphering the distant mystery that has intrigued mankind for millennia. By Adolfo Arranz
