If you like 'Voyage to the Planets' you should check out 'Planetes'. Almost a prequel to 'Voyage to the Planets' (but it's a Japanese anime production), the show follows the crew of a space garbage clean-up crew. In the later episodes they are involved in the preparation of a ship much like 'Pegasus' as it is made ready for a trip to Jupiter. As with 'Voyage to the Planets' almost all the science is realistic and it has the same 'true-to-life' feel as the BBC miniseries.
The show starts as something of a sit-com, but as the show progresses things get darker and deeper and it becomes a drama - and it's anime, but trust me, it's more than worth it to see another TV show that handles physics properly.
