An oldie but a goodie. In 1968 a bunch of entitled hippy bastards sent a letter detailing their specious demands to the Warden and Fellows of Wadham College, Oxford. This was their letter of reply, which speaks to how far the academy has since fallen.

COSMOS 2612 (SSC.68762) walks up to ICEYE-X36 (SSC.59103) In July we posted on the Cosmos 2609–2614 group. Back then we flagged COSMOS 2612 as the satellite best placed to reach ICEYE-X36. Three months later, it did. Analysis via COMSPOC SSA. On 1 October COSMOS 2612 raised its orbit ~47 km. The higher orbit gave it a fast catch-up drift, and it passed ICEYE-X36 at ~55 km on 5 October and again on 12 October. Within about two hours of the second pass it made two retrograde burns (~27 m/s total) and dropped back to ICEYE-X36’s altitude, ~515 km behind it. Between 13 and 16 October seven small burns (~5 m/s total) closed that gap. By 16 October COSMOS 2612 was in ICEYE-X36’s plane (within 0.003°) and at its altitude. Since the two share a plane, there are no plane crossings to wait for. From 16–18 October they spent ~24 hours within 2 km of each other and ~12 hours within 1 km. First pass was ~220 m (max uncertainty ~490 m) near 14:03 UTC on 16 October. It then held 2–4 km behind before drawing level on 17 October and settling into a centred safety ellipse around ICEYE-X36, which it held for the rest of the day. Closest pass in our solution was ~60 m (max uncertainty ~950 m) near 14:18 UTC. By late on 17 October it had drifted ~2 km ahead, then trimmed back for a third pass at ~260 m (max uncertainty ~160 m) near 01:58 UTC on 18 October. Relative speed at the closest points was 0.15–0.9 m/s, walking pace or slower. Slow walk-past, not a fly-by . ICEYE-X36 did not maneuver. COSMOS 2612 burned away at 12:30 UTC on 18 October, braked on 19 October, and is now holding ~480 km from ICEYE-X36 in the same orbit. We’ve seen this sequence before. COSMOS 2581, 2582 and 2583 (SSC.62902/62903/62904) have been running it against each other since February 2025: raise, phase, drop to co-altitude, close at under half a meter per second, hold, depart, loiter. Since August 2025 we’ve logged more than 170 sub-km conjunction events within that trio, several down to single-digit meters. Until now, every target had been one of their own. This is the first non-cooperative one. @planet4589 @shell_jim @IntegrityISR @ObservableSpace

New TLEs show that K2612 made a manuever on Oct 16 and is now stationkeeping within 5 km or less of ICEYE X36. To my knowledge this is the first LEO rendezvous of two active satellites where the owner of one of the sats did not give approval.
