Abstract

Claims (35)

1. A vehicle capture assembly for use with a capture vehicle, the vehicle capture assembly comprising:

a probe assembly including one or more retention elements for engaging with and securing a target vehicle; and

a probe movement feature coupled to the probe assembly, the probe movement feature comprising:

a central member coupled to the probe assembly;

a first platform for mounting the vehicle capture assembly to the capture vehicle;

a second platform configured to move relative to the first platform;

at least one movable union between the first platform and the second platform, the at least one movable union to enable the probe assembly to move in at least one degree of freedom relative to the capture vehicle, the central member configured to rotate and translate relative to the first platform and the second platform; and

at least one attenuation feature to dampen movement of the probe assembly relative to the capture vehicle.

2. The vehicle capture assembly of claim 1 , wherein the at least one movable union defines a universal joint.

3. The vehicle capture assembly of claim 2 , wherein the at least one movable union further comprises an additional union enabling the central member to translate relative to the first platform and the second platform and the probe assembly to translate relative to the capture vehicle.

4. The vehicle capture assembly of claim 2 , wherein the probe movement feature is configured to enable the probe assembly to translate in a direction transverse to axes of rotation of the universal joint.

5. The vehicle capture assembly of claim 3 , wherein the additional union comprises a prismatic joint.

6. The vehicle capture assembly of claim 2 , wherein the universal joint comprises a gimbal with two rotational degrees of freedom.

7. The vehicle capture assembly of claim 1 , wherein the at least one attenuation feature comprises one or more dampening members positioned around the probe assembly, each of the one or more dampening members configured to dampen at least one of rotation or translation of the probe assembly relative to the capture vehicle.

8. The vehicle capture assembly of claim 1 , wherein the one or more retention elements are configured to substantially define a universal joint with an inner surface of a docking cone of the target vehicle when the one or more retention elements are received in and engaged with the docking cone.

9. The vehicle capture assembly of claim 1 , wherein the second platform is rotatably coupled to a platform of the central member.

10. The vehicle capture assembly of claim 1 , wherein the central member extends through the first platform and the second platform.

11. A spacecraft capture system, comprising:

at least one vehicle capture assembly to be positioned on a capture vehicle, the at least one vehicle capture assembly comprising:

a probe assembly including one or more retention elements for engaging with and securing a target spacecraft;

an extendable lance coupled to the probe assembly;

a mounting platform for securing the at least one vehicle capture assembly to the capture vehicle; and

at least one movable joint to enable the probe assembly and the extendable lance to rotate and translate relative to the capture vehicle.

12. The spacecraft capture system of claim 11 , wherein the at least one vehicle capture assembly comprises three vehicle capture assemblies.

13. The spacecraft capture system of claim 12 , wherein the three vehicle capture assemblies are configured to substantially simultaneously retract each respective probe assembly of the three vehicle capture assemblies in order to secure the target spacecraft.

14. The spacecraft capture system of claim 11 , further comprising an attenuation feature configured to attenuate translational forces between the target spacecraft and the capture vehicle during a docking procedure.

15. The spacecraft capture system of claim 11 , further comprising an attenuation feature configured to attenuate rotational forces between the target spacecraft and the capture vehicle during a docking procedure.

16. A method of forming a vehicle capture assembly for capturing a target spacecraft, the method comprising:

coupling the vehicle capture assembly to a capture vehicle, the vehicle capture assembly comprising a probe configured to engage with and capture the target spacecraft;

enabling the probe to rotate and translate relative to the capture vehicle with a probe movement feature of the vehicle capture assembly; and

dampening at least one of rotation of the probe relative to the capture vehicle or translation of the probe relative to the capture vehicle with an attenuation feature.

17. The method of claim 16 , further comprising enabling the probe to extend toward the target spacecraft independently of the translation of the probe provided by the probe movement feature.

18. The method of claim 16 , wherein dampening with the attenuation feature comprises passively attenuating the target spacecraft with the attenuation feature.

19. The method of claim 16 , wherein coupling the vehicle capture assembly to the capture vehicle comprises coupling two additional probes to the capture vehicle.

20. The method of claim 16 , further comprising enabling the probe to rotate about two axes of movement.
