DSTE is a preliminary mission design tool that leverages cutting-edge multibody trajectory design and innovative data visualizations to enable rapid generation and analysis of complex space mission trajectories. DSTE’s visual interactive workflows streamline the trajectory design process, allowing designers to rapidly generate trajectory data and construct cost-effective pathways through sensitive multi-body systems.

Immersive, responsive trajectory exploration

Visualize highly dimensional trajectory data as never before. Identify, correlate, and explore patterns with detailed multidimensional trajectory maps for the cislunar regime and beyond. Periapsis Poincaré maps distill millions of trajectories into two dimensions and bring actionable insights to the surface. DSTE is built for performance with multithreaded parallel processing, serving up insights in an instant.

Multibody dynamics from concept to high-fidelity

DSTE’s multibody dynamics models enable the discovery of trajectories that leverage complex gravitational environments to achieve lower maneuver costs. Whether you’re headed to the cislunar neighborhood of Earth’s moon, exploring Near Earth Objects, or venturing to distant planetary systems, DSTE is ready to streamline your mission design process.

DSTE in print

DSTE is an enabling technology for research supporting the cutting edge missions of tomorrow.

DSTE supports the Lunar Gateway and Artemis programs, including planning for crewed transfers to the Gateway NRHO, providing abort initial guesses for Artemis missions, recontact/impact analysis for the Gateway (ensuring safe cubesat deployment), and end-to-end design of low-energy cargo missions to cislunar libration point orbits. DSTE has also supported Ocean World science orbit studies (planetary systems including Jupiter-Europa, Saturn-Titan, and Saturn-Enceladus).
