Parker Solar Probe expedition profile.

Parker Solar Probe is the Sun-target probe in this atlas. It uses a thermal-protection system, high-speed heliocentric orbit, and repeated Venus gravity assists to sample the solar corona and solar-wind acceleration region directly.

Expedition path

How the spacecraft travelled

Venus gravity assists lowered the spacecraft perihelion into repeated close passes through the solar corona and inner heliosphere.

Provided in-situ measurements from inside the solar corona and direct constraints on solar-wind acceleration, magnetic switchbacks, energetic particles, and near-Sun dust.

Science Payload

What this mission measured

Measurements

Electric and magnetic fields, plasma particles, energetic particles, imaging of coronal structures, solar-wind source regions, and dust environment near the Sun.

Target environment

The target reference is 0.046 AU in the compact simulator; solar-probe entries use close-solar perihelion distance while planet entries use the target world's solar orbit.

Review note

The canvas shows a clean teaching transfer and mission class. Exact flight dynamics require full ephemerides, maneuvers, launch energy, spacecraft mass properties, and operations timelines.

Why Parker Solar Probe matters

Provided in-situ measurements from inside the solar corona and direct constraints on solar-wind acceleration, magnetic switchbacks, energetic particles, and near-Sun dust.

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.
