Article VIII
A State Party to the Treaty on whose registry an object launched into
outer space is carried shall retain jurisdiction and control over such object,
and over any personnel thereof, while in outer space or on a celestial body.
Ownership of objects launched into outer space, including objects landed
or constructed on a celestial body, and of their component parts, is not
affected by their presence in outer space or on a celestial body or by their
return to the Earth. Such objects or component parts found beyond the
limits of the State Party to the Treaty on whose registry they are carried
shall be returned to that State Party, which shall, upon request, furnish
identifying data prior to their return.
Article IX
In the exploration and use of outer space, including the moon and other
celestial bodies, States Parties to the Treaty shall be guided by the
principle of co-operation and mutual assistance and shall conduct all their
activities in outer space, including the moon and other celestial bodies,
with due regard to the corresponding interests of all other States Parties
to the Treaty. States Parties to the Treaty shall pursue studies of outer
space, including the moon and other celestial bodies, and conduct
exploration of them so as to avoid their harmful contamination and also
adverse changes in the environment of the Earth resulting from the
introduction of extraterrestrial matter and, where necessary, shall adopt
appropriate measures for this purpose. If a State Party to the Treaty has
reason to believe that an activity or experiment planned by it or its
nationals in outer space, including the moon and other celestial bodies,
would cause potentially harmful interference with activities of other
States Parties in the peaceful exploration and use of outer space, including
the moon and other celestial bodies, it shall undertake appropriate
international consultations before proceeding with any such activity or
experiment. A State Party to the Treaty which has reason to believe that
an activity or experiment planned by another State Party in outer space,
including the moon and other celestial bodies, would cause potentially
harmful interference with activities in the peaceful exploration and use of
outer space, including the moon and other celestial bodies, may request
consultation concerning the activity or experiment.
Article X
In order to promote international co-operation in the exploration and use
of outer space, including the moon and other celestial bodies, in conformity
with the purposes of this Treaty, the States Parties to the Treaty shall
consider on a basis of equality any requests by other States Parties to the
Treaty to be afforded an opportunity to observe the flight of space objects
launched by those States. The nature of such an opportunity for
