BepiColombo MOSIF

BepiColombo MOSIF is catalogued in this registry as a component, held in the frame of Earth, from GCAT — artificial space objects.

Registry id GCAT_A09206 · source layer gcat · provenance PROCESSED — derived deterministically from source catalogues (unit, frame and epoch conversions, cross-source reconciliation) — no value invented

Exists from 2018-10-20 01:45:27 UTC (JD 2458411.57324) — no end date is recorded.

Open BepiColombo MOSIF in the live scene → The scene composes a position for any date and is where a figure becomes a picture. It downloads the whole catalogue first: measured against the built product, an object outside the core resolves after about 16 s over a local network and about 147 s over a 4 Mbit link, having transferred roughly 70 MB. If you cannot wait that long, this page is the answer.

Each row carries its own uncertainty and its own source. Where a row says no uncertainty is published, that is what the catalogue says — it is not a claim that the value is exact.

Trajectory, leg by leg

This object's parent frame changes over its life. Each leg names the frame it is expressed in and the source arc it came from. A leg with no geometry is a declared gap — the registry holds no path across it and draws none. This object has 37 legs; the table shows the first and last 12 and counts the rest.
