There's no telling what the future of space exploration could bring for mankind, but one thing that everyone seems to be able to agree on is that one day we'll have humans on another moon or planet besides the Earth.
Some time in the next 15-30 years, experts in the field believe we'll have people living on the Moon, or Mars. This matches up with NASA's plans to put a man on Mars, but there's still a lot of work to do to get that kind of habitation technology constructed.
NASA is confident that some day we'll explore the reaches of our entire universe, although time is definitely a factor. Getting the technology to get there means leaps in modern technology, and it's likely it probably won't have in our lifetime.
Nonetheless, it's really cool to hear from those in charge of the space program.
