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.
Two-body orbit from published elements
Mars Odyssey is placed by solving a Keplerian orbit around mars at the simulation time (a = 3,790 km, e = 0.009, period 0.1 d). Shown from 2001-10-24 onward.
Epoch2001-10-24T00:00:00Z
MethodTwo-body propagation of the stored elements by the shared orbit service; no perturbations.
LimitA two-body orbit ignores perturbations; positions drift from the true ephemeris away from the element epoch.
Bulk properties
Mars Odyssey: mass 7.250 × 10^2 kg. These values are bundled with the object record and drive the rendered size.
Close-up hull model
The close-up shows a published 3D model scaled to 6 m deployed maximum extent. Distributed through NASA 3D Resources; original mission-agency credit applies.
MethodSpace Time normalises the source model to the published deployed dimension.
LimitSource-asset presentation pose; time-dependent flight attitude is not modeled.
