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
MAVEN is placed by solving a Keplerian orbit around mars at the simulation time (a = 6,740 km, e = 0.47, period 0.2 d). Shown from 2014-09-22 onward.
Epoch2014-09-22T00:00:00Z
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
MAVEN: mass 2.454 × 10^3 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 11 m deployed solar-array span. 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.
