Juno

NASA spacecraft orbiting Jupiter to study its atmosphere, magnetic field, and interior structure.

Kepler elements Orbit 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.

Orbit Computed

Two-body orbit from published elements

Juno is placed by solving a Keplerian orbit around jupiter at the simulation time (a = 4,000,000 km, e = 0.98, period 53 d).

SourceBundled orbital elements
MethodTwo-body propagation of the stored elements by the shared orbit service; no perturbations.
LimitA two-body orbit ignores perturbations, and the object catalog does not record which element table these values were copied from.
Physical data Undocumented

Bulk properties

Juno: mass 1.593 × 10^3 kg. These values are bundled with the object record and drive the rendered size.

SourceBundled object record
LimitThe object catalog does not record where these values came from; treat them as unverified until the record is completed.
Appearance Reconstructed

Close-up hull model

The close-up shows a published 3D model scaled to 20 m deployed solar-array span. Distributed through NASA 3D Resources; original mission-agency credit applies.

SourceNASA 3D Resources · record juno
MethodSpace Time normalises the source model to the published deployed dimension.
LimitSource-asset presentation pose; time-dependent flight attitude is not modeled.
Description Undocumented

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.

What is not measured

  • Appearance: a reconstruction from measurements, not a direct observation. Close-up hull model. Source-asset presentation pose; time-dependent flight attitude is not modeled.

Not yet documented

  • Physical data: The object catalog does not record where these values came from; treat them as unverified until the record is completed.
  • Description: Background reading is linked under Further reading; it is not the source of the displayed numbers.
