To store items on your ship in Starfield, follow these steps:

• Enter your ship and go to the cockpit area. Near the pilot's seat, look for a screen or console labeled "Cargo Hold" on one of the side walls or a small screen fixed nearby

• Interact with the Cargo Hold console or screen to open your ship's storage inventory. You can also open the pause menu, select "Ship," then press the button (such as X on controller) to open the Cargo Hold menu

• Once in the Cargo Hold menu, press the inventory toggle button (like LB on controller or Q on keyboard) to switch to your personal inventory

• Select the items you want to store from your inventory and press the appropriate button (A on controller or E on keyboard) to transfer them into the ship's cargo hold

• You can store almost anything in your ship's cargo hold including weapons, armor, resources, apparel, and miscellaneous items. The only exception is other ships

• You can also store items in other containers on your ship such as the Captain's Locker near the cockpit, which is smaller but useful for organization

• If you are near your ship (within about 250-300 meters), you can also open the ship menu and transfer items to the cargo hold without entering the ship

• To increase your ship’s cargo capacity, you can purchase bigger cargo modules from Ship Services Technicians or acquire larger ships. The Payloads skill also increases cargo hold size

• Items placed on the floor inside your ship remain there and do not count against cargo capacity, but managing them can be cumbersome

In summary, access your ship’s Cargo Hold console in the cockpit or use the ship menu to transfer items from your inventory to your ship storage, allowing you to manage your inventory and avoid being over-encumbered while exploring
