DEFINITION:

Under this generic definition we include all the activities related with humanities as, for instance:

• History (humans have dreamed about spaceflight since antiquity. The Chinese used rockets for ceremonial and military purposes centuries ago, but only in the latter half of the 20th century were rockets developed that were powerful enough to overcome the force of gravity to reach orbital velocities that could open space to human exploration: that adventure continues today).
• Arts, entertainment and recreation, including museums and planetariums, as well as filming or any other artistic expression.
• Social studies related with space.
• Libraries and any database containing relevant data for space.
