P8-1

Hint
"Trade something for the martian samples and return them to the astronaut!"

Solution

 * Write an item to help you fly around (e.g. Wings/Winged Sandals/Helibackpack).
 * Write Gold/Diamond and carry it to each Martian. Once the question mark appears above them, they are no longer hostile. You can pick up the sample and bring it back to the astronaut. The same item can be used for all three Martians.
 * Once all three samples are carried back to the astronaut, the starite will appear.
