Abstract

A rocket landing stabilization system can include one or more upright support structures such as posts, columns, or walls, from which one or more stabilizing elements can be supported. The stabilizing elements can be used to stabilize a rocket as it lands at a landing site. The rocket landing stabilization system can also include a cradle, funnel, or cone to catch or otherwise support a rocket as it lands at the landing site. The rocket landing stabilization system can be located on land or at sea.

First claim

The invention claimed is:

1. A rocket landing stabilization system, comprising:
a funnel sized to receive a landing rocket; and
a stabilization structure positioned above the funnel, the stabilization structure including a first stabilizing element and a second stabilizing element, at least one of the first and second stabilizing elements movable with respect to the other of the first and second stabilizing elements to hold the rocket between the first and second stabilizing elements.

2. The rocket landing stabilization system of claim 1 wherein the stabilization structure further includes:
a first lateral support cable; and
a second lateral support cable spaced apart from the first lateral support cable;
wherein the first stabilizing element is a first stabilization cable coupled to the first lateral support cable and coupled to the second lateral support cable; and
wherein the second stabilizing element is a second stabilization cable coupled to the first lateral support cable and coupled to the second lateral support cable.

3. The rocket landing stabilization system of claim 2 wherein the first lateral support cable is coupled to a first upright support structure and the second lateral support cable is coupled to a second upright support structure.

4. The rocket landing stabilization system of claim 3 wherein the first and second upright support structures are columns.

5. The rocket landing stabilization system of claim 3 wherein the first and second upright support structures are walls.

6. The rocket landing stabilization system of claim 2 wherein the stabilization structure further includes:
a third lateral support cable positioned below the first lateral support cable;
a fourth lateral support cable positioned below the second lateral support cable and spaced apart from the third lateral support cable;
a third stabilization cable positioned below the first stabilization cable and coupled to the third lateral support cable and coupled to the fourth lateral support cable; and
a fourth stabilization cable positioned below the second stabilization cable and coupled to the third lateral support cable and coupled to the fourth lateral support cable.

7. The rocket landing stabilization system of claim 1 , further comprising a hook coupled to a rocket, the hook configured to engage the stabilization structure.

8. The rocket landing stabilization system of claim 1 wherein the stabilization structure includes a clamp system.

9. The rocket landing stabilization system of claim 8 wherein the clamp system includes a plurality of jaws.

10. The rocket landing stabilization system of claim 1 , further comprising a body of water under the stabilization structure.

11. The rocket landing stabilization system of claim 1 wherein the funnel floats on the body of water.

12. The rocket landing stabilization system of claim 11 wherein the funnel is coupled to at least one propeller to enable the funnel to be repositioned by the propeller.

13. The rocket landing stabilization system of claim 1 wherein the first stabilizing element is a first strap and the second stabilizing element is a second strap.

14. A method of stabilizing a landing rocket, comprising:
landing the rocket on a funnel; and
actuating a stabilization structure positioned above the funnel, wherein actuating the stabilization structure includes moving a first stabilizing element toward a second stabilizing element until the rocket is held between the first and second stabilizing elements.

15. The method of claim 14 , further comprising engaging a hook coupled to the rocket with the stabilization structure.

16. The method of claim 14 wherein actuating the stabilization structure includes clamping the rocket between a plurality of jaws.

17. The method of claim 14 wherein the stabilization structure is positioned above a body of water.

18. The method of claim 17 wherein the funnel is floating on the body of water.

19. The method of claim 18 , further comprising using a propeller coupled to the funnel to move the funnel through the body of water.

20. The method of stabilizing a landing rocket of claim 14 wherein the first stabilizing element is a first strap and the second stabilizing element is a second strap.

21. The method of stabilizing a landing rocket of claim 14 wherein the first stabilizing element is a first cable and the second stabilizing element is a second cable.
