How can we come back from Houston without visiting NASA? . I must say you get all sorts of feeling when you visit here. Amazed at the level of capability and intelligence of those who had made this a possibility. But at the same time, philosophy, god and all sorts of confusing and scary thoughts come up about the vastness and mysteries of outer space. The above pics are those of Saturn V rocket kept for display at Johnson Space center.
The wikipedia says - "It remains the largest and most powerful launch vehicle ever brought to operational status from a height, weight and payload standpoint".
