Was this the Saturday show where their rockets took off horizontally like airplanes? The flames looked like flares shooting out the back end (it probably was). For their spacesuits the helmet looked something like a deep sea diving helmet. Years later I learned that had been a 1940's movie serial. Can't remember the name of the show. Most of the kids Saturday TV programs in the 50's were recycled movie serials from the 40's. We were too young to know the difference. Even the Looney Tunes cartoons were adult cartoons from the 1940's. Those of us who remember those old shows think they are better than what's on today for kids.
