Mission Workbench / Educational model
Let the numbers
shape the mission.
Connect a physical interaction to force, acceleration and energy. Every scenario travels with its assumptions.
02 / THE IDEAL RESULT
Momentum exchange:
Constant-force estimate · not an orbit, trajectory or validated vehicle simulation
03 / KEEP THE ASSUMPTIONS
- Constant force, fixed total mass and nonrelativistic motion.
- No gravity, drag, orbit, guidance or braking model.

Light
Opaque normal-incidence sail: F = (1 + R)P/c. For sunlight, P = 1361 A/r². An ideal onboard collimated emitter gives F = ηPelectrical/c.
External fields
A straight current-carrying segment in a uniform external magnetic field has |F| = ILB|sin θ|. A complete tether architecture also requires current closure and environmental coupling.
Motion and range
Δv = Ft/m. Motion estimates above 1% of light speed are blocked. This tool cannot infer a propulsion mechanism from an entered force or calculate an interplanetary flight plan.
