How is Sita a symbol in the story?

The space probe sent to investigate the near-Earth object goes to Phobos to meet the Rama halfway. It is named after the god Rama’s partner or wife Sita who is known for her courage, purity, loyalty, and altruism. The unmanned capsule brings back the close-up photographs of Rama that enable the scientists to deduce its nature. The designation of Vishnu’s wife symbolizes the courageousness and selflessness of embarking on this mission into the unknown.
