NASA Space Trek Collection: Four Rooms Earth View/Houston DVD

Two more programmes compiled from the NASA archive. Pete Conrad presents 'Four Rooms Earth View', a feature on the colonization of space, including a look at the experiments carried out on Skylab. 'Houston I Think We've Got a Problem', presented by Walt Cunningham, gives an account of the ill-fated Apollo 13 mission, now a blockbuster movie in its own right.
