Space Simulation Toolkit |top| Site

For decades, humanity’s reach for the stars was limited by two harsh realities: the crippling cost of failure and the absolute impossibility of a physical test run. You cannot build a satellite, launch it, and hope for the best. If your orbital insertion burn fails in reality, millions of dollars and years of work simply vanish into the atmosphere.

Whether you are a student using GMAT to plot a course to Mars, or an engineer at Lockheed Martin stress-testing a reaction wheel, remember: In the simulation, you are allowed to crash. In reality, you are not. That is why we have toolkits. space simulation toolkit

KSP uses a simplified "patched conic approximation" (sphere of influence model), whereas professional toolkits use numerical integration of high-order gravity fields. However, the principle is identical: thrust prograde to raise your orbit. Because of KSP, a new generation of aerospace engineers enters university already knowing what a Hohmann transfer is. Consider the James Webb Space Telescope (JWST). It sits at Lagrange Point 2 (L2), a location 1.5 million kilometers from Earth. We cannot send a repair crew. Before launch, engineers ran millions of hours of simulation using custom toolkits to model everything from the unfolding of the sunshield to the thermal contraction of the mirrors in shadow.
