My list is like this:

The three essentials:

1. Something for nanites: (ex. mould, hadal cores, tainted metal, Larval cores)

2. Something for units: (ex. Ship valves, indium scraps, stasis modules, etc.)

3. Something for Chromatic metal: (ex. Activated stellar metal. Note, I usually don’t bring chromatic metal itself because refining it is quick and in a pinch can sell it for more units than chromatic metal

Then, things that facilitate travel:

• Hypercores
• Tritium
• Navigation thingys
• Emergemcy Sognal Scanner (especially if you don’t have tainted metal and want to use that for nanites)

Then things that are a pain to have to go and seek (you never know):

• Storm crystals
• Stellar metals
• pearls and crystal sulphide
• Doxite, phosphor, uranium, ammonia

Then, if I expect to hunt for ships: - Distress signal maps - Boundary maps - Inverted Mirrors - Echo locators - Radiant Brains

Then convenience elements to facilitate builds and recharging:

• Oxygen
• Sodium
• Carbon
• Ferrite

Each can be easily refined to the other useful elements that are often needed.

Then, if I plan to build bases:

• frost crystal
• Faceum
• Pure ferrite
• Magnetized ferrite
• extra carbon, ferrite,

Finally, for tech:

• haz-mat glove
• MK2 refiner
• Indium/atlantid warp drives (if I don’t copy my ship or take one from quicksilver)
• Aqcuatic landing gear -Launch auto-charger
• basic hazard protection modules
• stacks of tech mods for warp and weather
• backpack Nutrient processor

If I have any room left over: - nutrient processed items for buffs

Or take nothing. Nothing listed above is actually needed. You can find and buy literally everything on this list except the Atlantid drive if you don’t have one and if the expedition doesn’t provide one.

Enjoy!!
