Trajectory
The simulator uses the current heliocentric vector direction and propagates along the measured outbound velocity vector. The visual path is a study line, not a full reconstructed gravity-assist trajectory.
Interstellar spacecraft
Voyager 1 is leaving the solar system in real time.
Voyager 1 is the farthest operating spacecraft from the Sun, now travelling through interstellar space after planetary flybys and the heliopause crossing.

Live distance estimate
Voyager 1 now
Distance is propagated from a Sun-centered heliocentric ecliptic vector snapshot at 2026-05-11T00:00:00Z. The update uses the current browser time plus the same straight-line outbound velocity used in the simulator.

Science return
Why it matters
- Mapped Jupiter's weather, rings, magnetosphere, and moons with a flyby architecture.
- Transformed Saturn-system science and returned the Titan observations that helped shape Cassini-Huygens planning.
- Measures particles, plasma waves, magnetic fields, and cosmic rays beyond the heliopause.
Simulator Interpretation
How Voyager is drawn in the 3D lab
Distance scale
Use the Voyager heliopause scale in the simulator to fit the Sun, planets, and both spacecraft in one view.
Live readout
The selected spacecraft panel updates AU, kilometers, km/s, and km/hr as simulation time advances.
Mathematical model
Mission trajectory and spacecraft model
Mission visuals combine catalog dates, distance vectors, speed estimates, and schematic spacecraft geometry. They are not CAD-certified vehicle meshes unless a source model is explicitly loaded.
Vector propagation
\[\mathbf{r}(t)=\mathbf{r}_0+\mathbf{v}(t-t_0)\]
For live-distance spacecraft pages, current position is propagated from epoch vector and velocity when high-precision ephemerides are not bundled.
Transfer curve
\[\mathbf{r}_{\mathrm{curve}}(u)=\operatorname{Bezier}\!\left(\mathbf{r}_{\mathrm{launch}},\mathbf{r}_{\mathrm{mid}},\mathbf{r}_{\mathrm{target}}\right)\]
Mission path arcs are schematic transfer curves anchored at meaningful endpoints, not claims of exact reconstructed trajectories.
Dimensional hierarchy
\[T_{\mathrm{world}}=T_{\mathrm{parent}}RS\]
Spacecraft parts are placed with transformation matrices. This proves the generated geometry is internally consistent even when simplified.
Verification standard: the rendered object must be reproducible from stated equations, catalog parameters, or explicit geometric transforms. Visual reference images may inform presentation only; they are not the source of orbital positions, field vectors, accretion-disk gradients, timing, or engineering layout.
Limitations: browser scenes may use bounded scale, compressed distances, simplified two-body dynamics, schematic transfer curves, or educational approximations where full numerical ephemerides, CFD, finite-element models, or general-relativistic ray tracing are outside the page scope. Those simplifications are part of the model contract, not hidden image-based construction.
