While new formal space treaties (or major amendment of existing treaties) are unlikely in the near future, there are an array of informal mechanisms and national legislation and practice that occur to regulate space--what degree of formalism is most appropriate, do certain informal mechanisms work better than others, what factors impact government choices regarding the degree of formalism, how do the informal mechanisms interact with the formal treaties, will informal mechanisms have to become more formalized over time, how do new space actors impact the choice between formal and informal mechanisms, and among informal mechanisms, given rapidly evolving technology and commercial activities are informal mechanisms going to continue to be the major law making device, how does potentially increasing militarization impact choices between formal and informal mechanisms, what “gaps” or issues in existing law most need “filling” through informal or formal mechanisms, etc.
