Get close to the astronaut, then face him, and drop the gold bar (the same way you drop any object, by going into your inventory and dragging the object into either left or right edge of the screen).

If the astronaut hasn't walked away, he'll probably take the gold bar and turn bright green. Warning: there are multiple reports that the game starts to lag really bad after you have done this.
