At the "Ice World" location there's a large compound in the center. Dig it out and find the entrance, to unlock it you'll need three different access cards which can be located using your scanner. I would recommend you start searching the smaller rocks around before digging in the big one. Once you're inside you eventually get to a room with multiple doors, pass through the door straight ahead and jump down. You're then faced with a 4-digit code lock and that's what the colored digits on the walls are for, punch in the digits in the correct order and you'll find the antimatterbomb. Head back to the ship and upgrade your bombs from mini-nukes to antimatterbombs.

Just keeping mining, teleport back to ship, sell minerals, repeat.

At the "Small planet" location there's a large compound in the center. Dig it out and find the entrance, solve the 3 x 3 puzzle to unlock the door. Follow the path inside until you end up in the final room and interact with the shard on the table.

These are all the different artifacts that can be found. Use your scanner and look for the green dots, once all is cleared it will say "No signal". Everything isn't found right by the ship, if you look around you can see some rocks and debris off in the distance.
