SISPO: Space Imaging Simulator for Proximity Operations

Area of Science:

• Planetary Science
• Astrophysics
• Computer Graphics

Background:

• Accurate simulation of imaging instruments is crucial for space mission success.
• Existing tools may lack the fidelity required for complex surface and environment rendering.

Purpose of the Study:

• To introduce SISPO, a novel physically-based imaging simulator.
• To enable realistic simulations for small solar system body and terrestrial planet missions.

Main Methods:

• Utilizes Blender's Cycles rendering engine for physically based rendering.
• Incorporates procedural micropolygon displacement for realistic surface textures.
• Includes models for dust/gas environments and common image aberrations.

Main Results:

• Demonstrates capabilities for realistic surface and optical environment rendering.
• Simulates image aberrations including astigmatism and comatic aberration.
• Supports simulation of trajectories, light, and camera parameters.

Conclusions:

• SISPO provides a powerful framework for simulating space imaging scenarios.
• Enhances characterization of instrument performance and aids mission planning.
• Facilitates development of computer-vision algorithms for space exploration.
