Observatory

thumb|300px|right The Observatory is one of the activities in the Third Floor in JumpStart Adventures 3rd Grade: Mystery Mountain.

In the Observatory, Polly announces that she has sent one of her father's spaceships, containing a Mission Clue or Inventions Points, into deep space. She then beams a radio wave containing a clue as to the spaceship's whereabouts into a black hole. The user must then blast the clue out of the black hole before it is "sucked into another dimension" & then decode the clue with the Professor's Alien Transmission Decoding Device which he claims Professor Spark hasn't been used in a while since there are no alien signals to find-in a grammar activity. Once the hint is unscrambled, the user must use the Professor's star chart to determine which constellation Polly has sent the missing spaceship to.
