Well the last solo orbital mission prior to Liwei was Soyuz 3, piloted by Georgi Beregovoi, 26th - 30th October 1968. However the last person to orbit the Earth solo (and knowing your affinity to Apollo I'm guessing this is the answer you are looking for) was Command Module Pilot Dave Scott of Apollo 9 after the separation of the LM on 6th March 1969.
Am I correct sir?
I'll tell you Waspie, that was a tricky question.
YOU GOT IT RIGHT! If you hadn't mentioned Dave solo on Earth orbit...I'd have said, NOPE...! He was the last one to actually be solo on orbit around the Earth, and that was the criteria of the question!
The one prior to Dave Scott was actually Boris Volynov, on Soyuz 5 (although you're correct in that the last mission, designed and executed entirely solo, was Soyuz 3). The Soviets had these missions where they were doing rendezvous and docking on orbit, and transferring crew members from one craft to the other. Soyuz 4, on January 14, 1969 was occupied by one Cosmonaut at launch. Soyuz 5 launched the next day with three on board. Two of them transfered to the Soyuz 4 craft. Soyuz 4 re-entered with three Cosmonauts on January 17, and Volynov re-entered solo on January 18, 1969 in Soyuz 5.
Whatever...you got it right and the question moves to you!
