To repro, simply put some items on the ground above the rocket silo and press the "Travel to space platform" button. Your player will be placed at the tip of the rocket, hopefully right above the items lying on the ground. There, you can press F to pick up the items into your inventory, and they will be there once to travel to another planet. You can also pick up more items as the rocket is launching if you place them in a tall vertical line above the silo.

Log and my save file included, although I don't believe they are relevant

It wouldn’t truly be a trip to space without someone smuggling something aboard.

You could probably automate this by putting them on a belt north of the silo

Thanks for the report. This is now fixed for the next release.
