Every other file on this site keeps the newest element set and throws the previous one away.
That is why the Cosmos 2612 / ICEYE-X36 rendezvous of 18 October could not be reconstructed here:
by the time anyone asked, the only elements on disk were ten days past it and described the orbit
Cosmos 2612 left on, not the one it flew. This is the store that fixes it. One element set per
object is appended on each daily Space-Track pull, so a newly watched object starts with one row
and
fills to twenty over about three weeks; where Space-Track's history service allows, the
last twenty are also backfilled a few objects at a time.
