Abstract
A stress control mechanism for a space balloon is comprised of an axial tie member extending from the upper pole of a load carrying space balloon envelope, the tie member passing from the upper pole of the space balloon envelope through the balloon to an aperture located in a slideable member attached to the lower pole of the space balloon, a stopping member positioned at a pre-selected point on the axial tie member as a member for stopping the slideable member and thereby permitting the space balloon to assume a pre-selected shape upon inflation of the space balloon.
