Parker Solar Probe

NASA mission to study the Sun's corona. Will come within 6.2 million km of the Sun's surface, the closest any spacecraft has ever been.

JPL Horizons · to Dec 2029 Trajectory basis, the same label the app shows on the selection card.

Every aspect, with its origin

One record per aspect. The origin says what kind of thing each value is; the source says where it came from; the limit says what it cannot tell you.

Trajectory Catalog

Trajectory from Horizons state vectors

Parker Solar Probe's position is interpolated between 5,431 heliocentric state-vector samples from JPL Horizons that run through 2029-12-15. Past the last sample the marker holds its final position.

Epoch2018-08-13 to 2029-12-15
MethodJ2000 equatorial, Sun-centred position samples loaded from a versioned Blob snapshot. Historical encounter samples are preserved; active mission windows are refreshed daily by Trigger.dev in UTC. The app interpolates linearly between adjacent samples.
UncertaintyAccuracy depends on the mission ephemeris and prediction horizon. Linear interpolation adds error that grows with sample spacing (hours in the current window, finer around historical flybys). No trajectory covariance is stored.
LimitPosition only. Spacecraft attitude (which way it points) is not modelled, and no covariance is stored.

Description and facts

The short description and the fact list are written by the Space Time authors for orientation. They are not quoted from a catalog field and carry no citation of their own.
