Editing Pallas Deep-Core Survey (section)

== History ==

=== Commissioning and Pre-Survey Planning (2094–2096 CE) ===

Formal commissioning of the survey was recorded in late 2094 CE, following the release of a prospecting feasibility report authored in part by Dr. Solvei Mäkinen, then affiliated with the [[Hygiea Medical Consortium]]'s geological research division. Mäkinen's analysis drew on spectroscopic data gathered by automated probes between 2079 and 2082 CE, identifying an anomalously high bulk density region in Pallas's northern hemisphere that she designated informally as the ''Pallene Anomaly.''

Survey Commander Priya Vasanthakumar was appointed mission director in early 2095 CE. Her first priority was resolving the engineering problem that had stymied previous deep-drilling proposals for low-gravity bodies: conventional borehole casing systems relied on gravitational load to maintain stability, and on Pallas's near-negligible surface gravity, standard rigs could not sustain the lateral and torsional stresses generated at depth. Chief Engineer Bram Oduya, recruited from the [[Outer Belt Salvage Cooperative]], spent fourteen months designing a tensioned-anchor framework in which borehole casings were stabilized by an array of surface-driven tension cables, effectively transferring load from gravity to mechanical anchoring. The system was tested at reduced scale on a smaller belt body in 2095 CE before full fabrication was authorized.

[[Medic-Technician Lian Holt]] joined the crew roster in mid-2095 CE as the mission's primary medical officer and human-factors specialist. Her pre-deployment review of existing micro-gravity health literature identified significant gaps in protocol for personnel exposed to extended surface operations at gravity levels below 0.005 g — a regime distinct from both orbital microgravity and the relatively well-studied Martian surface environment established during the [[First Sustained Mars Surface Missions]].

=== Surface Operations and Initial Drilling (2096–2097 CE) ===

The survey fleet made orbital insertion at Pallas in March 2096 CE. [[Survey Station Pallas-Alpha]] was assembled over six weeks on the northern hemisphere near the edge of what early surveys had called the Pallene Anomaly region. Initial surface operations were marked by recurring anchor-drift incidents in which survey equipment migrated slowly across the regolith under the combined influence of micro-seismic activity and electrostatic surface charging. Oduya's team revised the anchor design twice in the field before achieving stable rig placement.

Shallow-core drilling began in July 2096 CE. The first 800 metres of subsurface revealed a fractured silicate zone of moderate density, broadly consistent with pre-mission projections but offering no commercial-grade deposits at accessible depth. Vasanthakumar elected to continue to intermediate depth rather than relocating the primary drill site, a decision later supported by the discovery of a transitional contact layer at approximately 1.1 km depth indicating an abrupt shift in material composition.

By late 2096 CE, the crew had established three secondary drilling sites at surface distances of 12 to 40 km from Pallas-Alpha, linked by a surface traverse system using low-thrust tethered hoppers. Secondary site data was relayed to the primary station via a short-range mesh network coordinated through the [[Deimos Relay Array]], which provided burst-mode communications with the inner system during alignment windows.

=== Deep-Core Phase and Major Discoveries (2097–2098 CE) ===

Full deep-core drilling at Pallas-Alpha commenced in February 2097 CE. By April of that year, the primary borehole had reached 3.1 km depth, where core samples retrieved by Dr. Mäkinen's team confirmed the presence of a dense nickel-iron matrix with trace platinum-group metal inclusions. Mäkinen formally designated the formation the [[Aldric Inclusion Zone]] in her field log, naming it after a notation used in the original 2079 probe dataset by an unnamed automated analysis subroutine.

The deepest confirmed sample was retrieved in January 2098 CE by secondary geologist [[Geologist Teodor Cruceru]], who led the drilling team that punched through a void layer at 3.9 km to reach a continuous nickel-iron stratum at 4.2 km depth. The sample — a 1.4-metre core of high-grade ferronickel — was described in Cruceru's field report as ''the most commercially significant single core extracted from a belt body to that date.'' The finding was transmitted to the [[Asteroid Arbitration Tribunal]] registry as required under interim belt prospecting conventions, establishing the consortium's discovery claim.

<blockquote>The depth and continuity of the Aldric Inclusion Zone exceeded pre-mission projections by a factor of roughly three. Some analysts at the time suggested the original spectroscopic models had been deliberately conservative to avoid attracting competing interests to the site before the survey was funded — a claim the consortium principals denied and which the Asteroid Arbitration Tribunal declined to investigate formally.</blockquote>

Lian Holt's medical records from this period documented seventeen cases of connective-tissue micro-strain attributable to repeated low-gravity surface EVA and manual equipment handling, leading her to implement mandatory tethered-rest periods and revised load-bearing protocols. Her compiled health guidelines, submitted to the [[Ganymede Magnetosphere Lab]]'s human factors division in mid-2098 CE, were later incorporated into standard belt-mission crew protocols.

=== Aftermath and Legacy ===

The survey formally concluded in October 2098 CE. All personnel were evacuated to transit vessels without loss of life, a notable outcome given the extended duration and difficult operating conditions. The primary scientific report, authored by Dr. Mäkinen and co-signed by Vasanthakumar and Cruceru, was distributed to major belt industrial interests and filed with the Asteroid Arbitration Tribunal. The [[Belt Foundry Accords|The Belt Foundry Accords]] of 2114 CE referenced the survey's findings when establishing baseline resource classification standards for mid-belt bodies.

The Pallas Deep-Core Survey had no immediate successor operation. Funding proposals for an extraction feasibility study circulated among belt industrial consortia for more than a decade before the resource jurisdiction debates that produced the [[Ceres Charter Compact]] in 2188 CE temporarily froze new extraction claims on undeveloped mid-belt bodies. The [[Pallas Independence Plebiscite]] of 2201 CE eventually cited the survey record as foundational evidence for Pallas's claim to resource sovereignty over its own subsurface.

Oduya's tensioned-anchor borehole system, patented through the [[Clarke Orbital Assembly Ladder]] industrial registry in 2099 CE, became the basis for a family of low-gravity drilling technologies used across the outer belt for the following century.
