Currently Valhalla is what would be considered a "foothold" world. It's is classificed friendly, has been effectivally pacified, and has an environment capable of supporting human life.
It won't be an effective base of operations until you have a functional space port with planetary travel ability in addition to planetary defensive positions and a seated rulership. Everyone currently planet side is either a sailor or a soldier (with the exception of any specialists who operate under senior staff like Gearus' engineseers or Illian's acolites).
If you want this place to become a stable coloney than you'll have to perminantly commit crew population to life planetside and begin "training" them on the various activities they will need to do. Since you have Crack Crew they will likely be very good at what they need to do, once they learn to do it.
Illian was directing the reconstruction of the command bunker but since you've call him back onboard for the survey Gearus as moved into that position and is personally leading the engineseers in assuring Servitor efficency. They are opening up the sealed pathways and replacing any damaged sections with whatever materials they have on hand (which is alot, they've probably brought some spare ship plating down to the surface to patch any damage).
Nathan is looking over everyone's shoulder and has directed some of Illian's men to keep aware for any sign of the ruinous powers among either the crew or the xenos, just in case, and has farther more sealed the Rosette which you acquired in a void box (unless Trask has ordered otherwise). Nathan has also developed the best communications methods with the xenos natives (because, after all, that is his job) and has been directing their efforts as required by Gearus and other staff.
On board ship your Navigator has been making peroidic trips to the bridge to use the Hood, watching for any warp activity which might be dangerous to Real Space. So far he's seen nothing of interest apart from the distant warp storms that ring the Expanse.
But onto current affairs:
Your scans show that the first moon (currently designated Orbital Mass One until it is otherwise titled) is indeed an extremely dense ball of stone and ore. Strong iron presence along with copper, cobolt, titanium, silver, and trace metal. Also a strong cloride salt response on much of the surface and sub-surface layers of material.
