Tips for Using Space Writing Prompts

A. Expanding a Prompt into a Full Story

Start by asking yourself key questions: Who is the protagonist? What is the main conflict? What themes do you want to explore? Use the prompt as a foundation, but let your imagination take it in unexpected directions.

B. Combining Multiple Prompts for Deeper Narratives

Mixing prompts can add complexity to your story. For example, an astronaut stranded in space (Survival & Adventure) could discover a wormhole leading to an alternate dimension (Time & Alternate Realities). This combination can create a rich, layered narrative.

C. Exploring Different Genres with Space Themes

Space stories aren’t limited to science fiction. They can incorporate elements of mystery, horror, romance, or even comedy. A ghost ship drifting in space could make for a terrifying horror story, while a lonely astronaut forming a deep connection with an AI could be a touching romance.
