Europa Clipper

NASA orbiter en route to Jupiter to study the icy moon Europa and its subsurface ocean over dozens of flybys.

JPL Horizons · to Mar 2030 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

Europa Clipper's position is interpolated between 1,410 heliocentric state-vector samples from JPL Horizons that run through 2030-03-18. Past the last sample the marker holds its final position.

Epoch2024-10-15 to 2030-03-18
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.

Bulk properties

Europa Clipper: mass 6.065 × 10^3 kg. These values are bundled with the object record and drive the rendered size.

The close-up shows a published 3D model scaled to 30 m deployed solar-array span. Distributed through NASA 3D Resources; original mission-agency credit applies.

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.

SourceSpace Time editorial text

Trajectory coverage: 2024-10-15 to 2030-03-18 (1,410 samples). Outside that window the marker holds its last known position.

What is not measured
