Survival training seems a bit too wide. Especially the part about edible plants on a new world. It’s hard to learn about edible plants around planet Earth, let alone the other planets.
What about interacting with other civilizations on the planets, both known and unkown?
I recommend adding two skills.
The first one should be Meteorology or Climatology, the studies of weather and climate. That would even be useful on our last mission, but I think it can be used even on approach to planets.
The other one is either Archeology (study of ancient civilizations), Paleontology (study of fossils), or Anthropology (science of evolution). I think the skill we use should cover all three areas.
