midnight
Manufacturers yearned to have their products used in connection with the hottest news story in decades . There was a steady trailing of moon-jeeps from the airlocks of Lunar City to the ship . The time of lunar sunset arrived -- 503:30 o'clock , half-past five hundred and three hours . Time was measured from midnight to midnight , astronomical fashion . The great , blazing sun whose streamer prominences , even , were too bright to be looked at with the naked eye -- the sun neared and reached the horizon . There was no change in the star-studded sky . There were no sunset colorings .
