Lost In Space

This simple introductory game is used as part of our Introduction To Python programming course. It's also a very simple single player game that you can use to get used to coding bots on the site.

Objective
Guide your spaceship from its starting position to the docking station.

A description of each field in the gamestate.
Key
Description
Grid
A list of integer lengths of ships that both you and your opponent are expected to place on the board.
MyPositionRow
The current row that your spaceship is on in the Grid.
MyPositionColumn
The current column that your spaceship is on in the Grid
DestinationPositionRow
The row that the docking station is on
DestinationPositionColumn
The column that the docking station is on
FuelLeft
The amount of fuel you have left
Shields
The amount of power left in your shields
MovesMade
The number of moves you have made so far in this game
Code
The code that you will need to decypher in games that require a code to be submitted to authorise a move.
IsMover
A Boolean value indicating whether it is your turn to move. It will always be true when in the calculate_move() function. (Delve deeper into the code if you want to do some processing during your opponent's turn.)
ResponseDeadline
The epoch time, in milliseconds, that a successful move has to be sent and received by to prevent you from timing out.
GameStatus
A string that will have value "RUNNING" if the game is in progress or a reason the game has ended otherwise
Understanding the grid
The strings in your grid can contain the following values. Not all games styles include all of these values:
SPACE - One more little piece of the dark black emptiness that is outer space
SHIP - Your spaceship
DESTINATION - The destination that you must navigate to
OBSTACLE - An obstacle, such as space debris, that you must avoid
Making a valid move
A valid move in Lost In Space varies depending on the game style. 
The basic game style simply requires that you return the direction that you want your spaceship to move in, using compass points. The valid options are N, E, S, W, NE, NE, SE, SW.
The move is returned as JSON, as shown in the example below
return {"Direction": "S"}
Some gamestyles need you to submit a secret code in order for a move to be authorised. The format of the move for these game styles includes an Authorisation field as follows:
return {"Direction": "S", "Authorisation": "123456"}
