Some facts about Apollo 13 are that it really faced a major crisis in space. There was an oxygen tank explosion which endangered the lives of the astronauts. Fiction might be any made - up stories about secret missions during that flight that have no basis in the real events that were documented.
I'm not sure specifically what the 'hestia story' is without more context. It could be a fictional story, a personal account related to someone named Hestia, or something else entirely.
Let's assume Hestia's story. Hestia was a kind-hearted goddess. She was in charge of the hearth, which was the center of the home in ancient times. One day, a poor family was struggling to keep their home warm during a harsh winter. Hestia noticed their plight. She sent a gentle warm breeze into their home, making the hearth burn brighter without using more wood. The family was amazed and knew that it was a blessing from Hestia. From that day on, they always made offerings to Hestia and told everyone about her kindness. And Hestia continued to watch over all the homes and families, spreading her warmth and love.
The story of Hestia for kids is usually about her being a kind and gentle goddess who takes care of the home and hearth. She brings warmth and comfort to those around her.
Some fanfictions might also take a more creative approach. They could place Apollo in alternate universes, such as a world where the legal system is completely different. In this setting, Apollo Clay has to adapt to new rules and challenges, which makes for an exciting read as we see how his core values as a lawyer are tested in these strange new scenarios.
Apollo 18 isn't real. It was created for entertainment purposes and doesn't represent actual events. The story was made up to thrill and engage the audience.
