SPACETRC / INTERACTIVE LABORATORIES
Change a variable.
See the relationship behind it.
Investigate basic space-engineering concepts with explained models. Each tool states inputs, units and limits clearly, turning a result into the next question.
RocketLab
Investigate how specific impulse and mass ratio affect ideal velocity change.
Explore ↗
OrbitLab
See altitude, inclination, speed and period relationships around Earth in two and three dimensions.
Explore ↗Mission design
Compare mass budgets and stages using Earth-observation or communications scenarios.
Explore ↗HOW TO USE THE LABORATORY
First a prediction. Then a comparison.
Narrow the question
Choose one relationship, such as “What happens when payload increases?” Decide which inputs remain fixed before starting.
Change one variable
Read the difference together with its units. Consider effects excluded by the model separately from its result.
Return to the source
Check the equation and assumptions in the guide. Discuss why a model is only one part of actual flight or mission design.
