A system for capturing a capture feature on a free flying spacecraft, comprising: a capture mechanism including i) a quick grasp mechanism mounted for movement in a housing, said quick grasp mechanism including at least two spaced pairs of grasping jaws and a closing/opening mechanism connected to said at least two pairs of grasping jaws for closing/opening each pair of grasping jaws, each of said at least two pairs of grasping jaws being pivotally mounted to said housing and configured to be rotated with respect to each other, wherein a positioning mechanism is operably connected to each of said at least two pairs of grasping jaws for adjusting the angular position of each of said at least two pairs of grasping jaws to accommodate launch adapter rings, or capture features, of different radii, said quick grasp mechanism being configured for forcing said at least two spaced pairs of grasping jaws together around said capture feature to grasp the capture feature; ii) said at least two pairs of grasping jaws configured to accommodate local variations in size and shape of the capture feature at at least two locations on the capture feature being grasped by said at least two pairs grasping jaws; and iii) a rigidizing mechanism including a rigidizing contact feature, said rigidizing mechanism being configured to force the grasping jawsof each of said at least two spaced pairs of grasping jaws further together to a closed position and at the same time driving said rigidizing contact feature into contact with said capture feature within said at least two spaced pairs of grasping jaws to secure said capture feature within said closed grasping jaws between said rigidizing contact feature and said closed grasping jaws, to rigidize the capture feature and the spacecraft. i) a quick grasp mechanism mounted for movement in a housing, said quick grasp mechanism including at least two spaced pairs of grasping jaws and a closing/opening mechanism connected to said at least two pairs of grasping jaws for closing/opening each pair of grasping jaws, each of said at least two pairs of grasping jaws being pivotally mounted to said housing and configured to be rotated with respect to each other, wherein a positioning mechanism is operably connected to each of said at least two pairs of grasping jaws for adjusting the angular position of each of said at least two pairs of grasping jaws to accommodate launch adapter rings, or capture features, of different radii, said quick grasp mechanism being configured for forcing said at least two spaced pairs of grasping jaws together around said capture feature to grasp the capture feature; ii) said at least two pairs of grasping jaws configured to accommodate local variations in size and shape of the capture feature at at least two locations on the capture feature being grasped by said at least two pairs grasping jaws; and iii) a rigidizing mechanism including a rigidizing contact feature, said rigidizing mechanism being configured to force the grasping jawsof each of said at least two spaced pairs of grasping jaws further together to a closed position and at the same time driving said rigidizing contact feature into contact with said capture feature within said at least two spaced pairs of grasping jaws to secure said capture feature within said closed grasping jaws between said rigidizing contact feature and said closed grasping jaws, to rigidize the capture feature and the spacecraft.
