Technology: A civilization of pioneers and explorers will certainly have a large number of engineers and entrepreneurs. Their ambitions will invigorate large segments of the population - just as people of the 20th century have been thrilled and motivated to study rocket science when the American President J.F. Kennedy told them "we want to go to the moon". All depends on what kind of visionary ideas people will have 1000 years from now. The most obvious fronteer certainly will be the planets of our solar system (if they have not already been colonized) or even the planets of other solar systems within our own galaxy. But the new frontier may also be a new kind of social order - such as a society of "uploaded brains and personalities" in computers. This "virtual human species" would "live" in the digital (or perhaps quantum-computer based) world of highly advanced computer systems and databases.
Natural Environment & Resources: The natural environment will probably be valued and preserved in a pioneer civilization of the future, but more in the sense of nature preserves. In fact, people might distance themselves from the natural environment of our planet and spend most of their lifes in techno-cities and industrial facilities. Just as the 50% of urban population in the early 21st century, they will have little connection to the countrysiede and the natural environment. They will mostly live in a technical, man-made world.
Economic Structure: The economy is very important for a pioneer civilization. Space exploration is expensive and this civilization will only succeed to follow their dreams when they have a highly productive economy. While robots and advanced AI systems will do most of the work and economic planning, entrepreneurs are needed to come up with innovative ideas and schemes. Probably we will have space tourism and adventure trips to pay for some of the explorative work. There might also be elaborate schemes to mine meteorites or other planets for valuable resources. State-capitalism, as we currently have in China, might be the appropriate form of economic activity in a pioneer society. It was not by accident that space exploration started in the 20th century with state-controlled agencies in the US, USSR and China. Private businesses only started to get into space exploration by the early 21st century.
Social conditions: A pioneer civilization needs an entirely different social organization than - for instance - a hedonistic society. People are required to become disciplined, well trained members of large teams. You can't conquer a new fronteer with a gang of lazy, undisciplined hedonistic individuals who do whatever they just like to do. It is the same difference as between the control-room for the Saturn 13 trip to the moon and Jimmy Hendrix playing at the Woodstock Festival. While the social organization of a pioneer civilization will require discipline, it will not be extremely hierarchical or violence-based, such as in a warrior society. Pioneers are more like groups of professional colleagues, where each member has a particular task and talent. The high degree of organization will emerge from the shared objective - not from a command and control structure or authoritarian rule.
Spiritual & Religious Orientation: Religion and spiritual experience does not rank high for a pioneer civilization of the 30th century. People might have their own beliefs and spiritual callings - but the civilization as such will focus on technology and organization. However, there will certainly be some kind of "can do" spirit in this pioneer society - quite similar to the attitude of the American Settlers conquering the "Wild West".
