Administration Report: Kiernan 40592d (“Convoy”), security rating “Standard”
The first exploration of the human-habitable exoplanet Kiernan 40592d, informally referred to as “Convoy,” revealed many mysteries upon close orbital observation, including the fact that Convoy has almost no axial tilt. An axial tilt of .0000335 means that the planet has no discernable seasons; two large rocky moons and one metal-rich moon (possibly the remnants of a planetary core from the early days of the Kiernan 40592 system) contribute to a wider range of tidal effects than seen on Earth, but the wide expanses of land between water masses should have precluded the development of Convoy’s surprisingly Earthlike biota. The reason behind that variety lies with one of the first features spotted during the original survey: a cluster of artificial discs or “islands” moving slowly across the planet at the rate of approximately 500 meters per solar day. When first spotted, a member of the survey team noted that the cluster resembled a human pancreas, hence its informal name “The Langerhaans Archipelago.”
Over 4000 islands comprise the cloud, levitating above the planet’s surface and moving through an unknown technology. The islands range wildly in size, shape, diameter, altitude, and inclination, but all share a rock and soil top crust with a metallic rim and base, with a maximum diameter of 500 meters, The vast majority of the islands remain within the cloud, but some have been tracked breaking from the cloud and moving vast distances for unknown reasons before returning to the cluster, and others stopping on the surface and becoming covered with sediment or volcanic deposits. For the most part, however, individual islands stay at a consistent altitude and position within the cloud. The cloud itself moves in a circumpolar “orbit,” moving from arctic to equatorial latitudes and transporting life forms with them. (In extreme circumstances, the cloud moves around drastic changes on the surface, such as around the extensive shield volcano complex in the northern hemisphere when eruptions are ongoing.) In fact, at least one-third of the documented life on Convoy is only known from the Archipelago, with half of that endemic to one to three islands. Others disembark or die back as temperatures rise or fall, remaining at a particular latitude until the Archipelago returns.
The movement of the Archipelago is so consistent that an analogue to terrestrial flowering plants has evolved within the cluster, with “males” living on the surface and passing genetic material to “females” on the islands, who then scatter new plantlets on islands and the planet surface below. As temperatures and sunlight intensity change, many parent plants die back to corms until their optimal conditions return, thus causing drastically different appearances to islands depending upon the latitude at which they are located. Others remain with the Archipelago for their entire lives, with the change in latitude instigating stages in their life cycles such as metamorphosis and reproduction,
This arrangement has been in place for a very long time: radioisotope dating of the crust is problematic because of unknown factors involving erosion and redeposition and dating of the discs is nearly impossible, but most models suggest that the Archipelago is between 500 million to one billion standard years old. Since the Kiernan 40592 system is approximately two billion years younger than Earth’s, this suggests that the Archipelago was put into motion shortly after the planet’s crust cooled after its original formation.
Although no other trace of the cloud builders remains on Convoy or anywhere else within the planetary system, artifacts and debris from at least three advanced civilizations, two of which previously unknown, have been found both on individual islands and on one of Convoy’s moons. Likewise unknown is whether the Archipelago’s life forms evolved independently on Convoy or if they were transported by the cloud builders. Either way, extensive Administration research continues on understanding nutrient acquisition and transfer between Convoy’s surface and the islands, interactions between animals and plants across the cloud, effects of the cloud’s passing on biology and geology on the surface below. Permanent bases on Convoy’s surface are banned, and most exploration is done with a combination of drones and very carefully monitored human and robot activity.
Isolated islands have been found in a seemingly nonfunctional state, although longterm observation confirms that some of these “nonfunctional” platforms are in a sort of standby mode, possibly to establish particular plants, animals, and/or protists before rejoining the rest of the Archipelago. Several attempts have been made by Administration scientists to study the internal structure of the islands, but these have been hampered by a combination of the extremely tough composite structure of the outer shell and the equally advanced nanostructures within. Even cutting beams at the absolute lower limit produce a kerf wide enough to inhibit or disable island function, with one researcher (Stuyvesant,08311193-664-5) describing available technology as comparable to “shotgunning a Stradivarius to learn how to play it.”
Because of the discovery of islands going dormant but remaining functional, and the islands’ function in preserving and revitalizing the planet’s ecology, any attempt at damaging or disabling an island, or approval of any attempt, can and will be punished by a minimum of a loss of ten years’ income, incarceration in Administration facilities for a minimum of seven standard years, and a total permanent reversion of all privileges and clearances associated with advanced degrees or military rank. This has not stopped “accidents,” but it has slowed them to a crawl. Further research into the islands is overseen by Administration authorities, with full biohazard protocols applying at all times due to the similarities of Convoy’s ecosystem to that of Earth. Unauthorized visits to Convoy’s surface will be prosecuted to the maximum extent of Administration law.
