Space Ending

The Space Ending is the final ending in PDTA, and it is really difficult to get.

 * Press the red button twice to reveal a 3 button panel.
 * Enter the code I III II II III I (1 3 2 2 3 1) in the new panel to reveal a lever.
 * Pull the lever to the left to reveal a ten-digit panel.
 * Input 2001 into the panel to reveal a 3-digit dial.
 * Spell out the word PL U TO with the letters and press the grey button underneath them to acquire a key. (EARTH In Remake).
 * Press button 6 more times to reveal your screwdriver.
 * Drag the screwdriver to the panel on the top right to reveal a set of 4 coloured buttons
 * Press the red button 4 times to reveal a keyhole. (Press the yellow button 4 times in the remake.)
 * Drag the key into the keyhole.

Trivia
The code you need to use is 2001. This is obviously a reference to the movie 2001: A Space Odyessy, but the devs say it ISNT.

This rocket in the ending was supposed to go to/from the Pluto (or earth), as that is the 2nd code you need to use to get the ending and to get the key. But it shows that the rocket goes way faster, like using the spacewarp, just like the film reference.

At the end of the ending, a upside-down baby appears, it refer from the "Star Child" from the film's ending.
