DEFINITION:

Any time where a vehicle flying up to space (internationally considered as flying at an altitude higher than 100 km) has any human being inside, we are doing a manned space flight.

Space development has always included manned space systems and, although the robotic exploration has made a lot of advances, the interest to fly to the space has been renewed in the last decade with the concept of space tourism and the more recent objective of going to Mars, probably coming back to Moon first.

Development of manned systems and long duration space travelling are currently acting as research and technology tractors for many other space and non-space technologies.
