Phobos LIBS Assay Atlas

The Phobos LIBS Assay Atlas collects every Spectra Assay Lance shot the Guild has fired on the Martian moon: 14,200 georeferenced sample points gathered by rover crews and prospectors on foot since 2181.

Each record includes the raw laser-induced breakdown spectrum, the calibrated element concentrations and the operator's field notes. From those points the team has interpolated a rare-earth grade map in grams per tonne covering 70 per cent of the surface. Short shallow cores taken by Lodeseeker Prospector Rovers are logged too, so you can compare surface readings with what lies a metre or two down.

The atlas is dedicated to the public domain under CC0-1.0. Mars-side universities use it to teach spectroscopy, and the Phobos Regolith Syndicate uses it to plan pit expansions on the Stickney Rim. Senior Geophysicist Teodor Vasquez-Lin curates the release from Stickney Station, and new data is appended monthly.

Each month's additions come with an updated grade map, and every point keeps its original spectrum so anyone can recalibrate it with a newer AssayKit release. The atlas also covers Deimos-facing slopes rarely visited by rovers.
