It was equal to the job. Its ultra-sensitive receivers picked up and identified every major planetary body in the solar system and sent the information through an over­lapping labyrinth of seventy-two circuits where every navigation fac­tor of location, spacial relation, planetary gravital pulls, ship’s speed and acceleration and deceleration, planetary speeds and orbits, ship’s destination, and so forth, were sec­ond by second electrically arranged and coordinated into the necessary resultant course; and it put the ship on that course, and corrected in­finitesimal strayings, and would without attention start deceleration at the proper time, and bring the ship gently to ground in a place re­served for it in Earth’s great space port at New York. All that Allison had to do, therefore, was set the buttons for destination and accelera­tion.
