Sourced from Wikidata (community-maintained structured data, whose statements link to their own citations where provided); each value carries its Wikidata QID. A field with conflicting Wikidata values is omitted. Launch date is used only to cross-check the catalogue, never to override it. Fields Wikidata did not provide, or where conflicting values exist, are omitted, never invented.

Derived values

Computed from source-backed inputs via standard formulae — not observations. Every input and constant is traced below.

  • Time since launch5.9 yearscalculated
    Formula & inputs

    Formula: Δt = reference − launch (v1.0.0, impl v1.0.0)

    Inputs:

    • launchDate = 18466 days (JD-like) · NASA

    Limitations: A time-dependent value: it is elapsed time as of the stated reference instant, not a fixed total.; Elapsed time since launch is not the same as time spent operating at the target.

    Uncertainty: not propagated (inputs carry no catalogued uncertainty)

    Computed as of 2026-06-29.

Outcome & discoveries

Made China the second nation to land and operate a rover on Mars.
