Manoeuvres

Every lasting step in an object’s orbit that the breakups project reads from the public orbital elements, newest first. The unusual ones are listed one by one; a constellation’s routine steps of a day fold into one row, and older months are on their own pages.

The record began on November 7, 2026; nothing before that day is held.

The record holds no step yet. It takes the breakups project’s steps once a day from its first day on, so an empty list here does not mean nothing has moved.

How a manoeuvre is known

What is read: Every object’s public orbital elements, by the breakups project’s detector. A manoeuvre is an accepted step: a lasting change in an object’s orbit between two of its element sets, the last before and the first after, that held in the sets that followed.
What it says: The change in mean altitude, perigee and inclination, the change of speed it implies along and across the orbit, the two sets it fell between, and its class, read against the object’s own history of steps: station-keeping, campaign, disposal, occasional or unique.
What it never says: Why it was made: the class says what a step looks like, never its reason, and an operator’s intent is the operator’s to state. Debris and rocket bodies drift, and are never said to have manoeuvred.
When it is read: Once a day, after the detector’s run, so a manoeuvre shows up to a day after its second set.
