## What it is
OpenSpace is an open-source interactive astrovisualization application that renders the entire known universe, from planetary surfaces to galactic structure, using real mission data from NASA, ESA, and research institutions. It supports planetarium domes, museum exhibits, classrooms, and personal computers with an extensible architecture for tiled displays and synchronized multi-venue experiences.

## Use cases
- visualize the known universe interactively
- render planetary surfaces from spacecraft imagery like HiRISE and LRO
- replay space missions with accurate trajectory data in a planetarium
- create museum exhibits with synchronized multi-screen space visualizations
- teach astronomy in classrooms with live mission data
- visualize scientific datasets like solar magnetic field lines or galaxy catalogs
- drive a planetarium dome with multi-projector blending and fisheye support

## When to choose
- you need scientifically accurate, data-driven space visualization rather than artist approximations
- you run a planetarium, museum, or classroom and want free cross-platform software
- you need continuous navigation across scales from Earth's surface to the edge of the observable universe
- you want to visualize real mission trajectories using SPICE kernels from NASA and ESA

## When to avoid
- you need a lightweight web-based star map or mobile stargazing app
- you only want simple 2D charts or plots of astronomical data
- you lack a modern GPU or cannot run a desktop graphics application
- you need a general-purpose scientific plotting library rather than an interactive universe explorer
