Feeling glad to become part of your team, Phoenix. Now let's get straight to business.
I have read trough recent stratosphere flight report and compared this with initial data already known about Palmyra to stumble upon some interesting facts. Vessel's telemetry and previous cursory scans are quite similar regarding gravitational accelerations which brings us to about average 1,55G on surface level.
This leads to two conclusions - the first one is that also considering its radius we can say that Palmyra much more dense, as from it looks like from above with glaciers scattered all across the surface, and surely has metallic core, that produces magnetosphere strong enough so background radiation planetside could be much lower than up here, on Kadesh. So we can spare some landing mass on more useful equipment than radiation shielding. The second is that constantly experienced higher than normal gravitation will affect on future residents for sure, which raises a major concern about their health, so acquiring gravity-field equipment is strongly recommended in long shot.
Also, due to unwelcoming environment of blizzards, roaming on high speed within Palmyra's thin atmosphere and same increased gravity issue the idea of establishing small automated outpost on potential landing site simply won't do. We need something sizable, though any ship from Great Voyage flotilla really counts, which gives me an idea... We could use not a vessel, but a vehicle for our first mission on surface. Not only it will be able to withstand all challenges, but also it could ride around designated area, providing us with more precise information about surface climate, temperatures and geological activity.
Designing and producing such is obviously impossible for us at the moment, but I do believe such companies as PlanetForm or EFL can offer us a decent remote rover with all equipment already included. Another possible solution is asking our Order neighbors or House representatives for a military vehicle, also military grade, but "little" repurposed by excess armor and weaponry removal.
Overall, Palmyra as mysterious for us as it is now, seems like an opportunity of establishing a settlement that combined with Kadesh on orbit could make the whole flotilla and Phoenix quite self-sustained in terms of resources. But there's so much work to be done before this one comes true.
