An adapter for connecting at least a first rocket stage of a space vehicle to a second rocket stage of the space vehicle. The adapter is configured to separate with the first rocket stage when the first rocket stage is separated from the second rocket stage. In one embodiment, at least a portion of the adapter is configured to itself separate from the first rocket stage, subsequent to separation of the first rocket stage and the second rocket stage. A second portion of the adapter remains with the first rocket stage to facilitate a controlled descent and flight of the first rocket stage back to the earth's surface.
