Apollo 17 left for the Moon just after midnight, 46 years ago. It was the only night launch and it was the last manned flight out of Earth orbit and to the Moon.
Any hope of continuing died when Nixon was elected. He was as implacably and irrationally hostile to anything championed by John F Kennedy as Trump has been vs Obama.
The Saturn production line was shut down and the expertise lost.
