An apparatus for lowering an orbit of a space object includes an envelope, an inflation system for inflating the envelope, an inflation control system for controlling the inflation system, and attachment hardware for connecting the apparatus and the space object. Inflating the envelope increases an effective drag area of the envelope for increasing atmospheric drag on the envelope.

1. An apparatus for lowering an orbit of a space object, comprising:an envelope;a spatial-separation element for providing a complete spatial separation between the envelope and the space object;an inflation system for inflating the envelope;an inflation control system for controlling the inflation system; andattachment hardware for connecting the apparatus and the space object, whereininflating the envelope increases an effective drag area of the envelope for increasing atmospheric drag on the envelope. 2. An apparatus according to claim 1, wherein the spatial separation element includes a mast. 3. An apparatus according to claim 1, wherein the spatial separation element includes a tether. 4. An apparatus according to claim 1, wherein the inflation control system includes a timer having a reset mode. 5. An apparatus for lowering an orbit of space object, comprising:an envelope;an inflation system for inflating the envelope;a spatial-deployment system for separating the apparatus and the space object in a deployed configuration, the spatial-deployment system including a reefing system that encloses a portion of the envelope before inflation and constrains the envelope during inflation;a spatial-deployment control system for controlling the spatial-deployment system;an inflation control system for controlling the inflation system; andattachment hardware for connecting the apparatus and the space object, whereininflating the envelope increases an effective drag area of the envelope for increasing atmospheric drag on the envelope. 6. An apparatus according to claim 5, wherein the reefing system includes a reefing sleeve. 7. An apparatus according to claim 5, wherein the inflation control system includes a timer having a reset mode. 8. A method for lowering an orbit of a space object, comprising:connecting an envelope to the space object;using a spatial-separation element to provide a complete spatial separation between the envelope and the space object; andcontrolling an inflating of the envelope, whereininflating the envelope increases an effective drag area of the envelope for increasing atmospheric drag on the envelope. 9. A method according to claim 8, wherein using the spatial separation element to provide the complete spatial separation includes:connecting a first end of a mast to the envelope, andconnecting a second end of the mast to the space object. 10. A method according to claim 8, wherein using the spatial separation element to provide the complete spatial separation includes:connecting a first end of a tether to the envelope, andconnecting a second end of the tether to the space object. 11. A method according to claim 8, further comprising: controlling a deployment of the complete spatial separation between the envelope and the space object. 12. A method according to claim 11, wherein controlling the deployment of the complete spatial separation between the envelope and the space object includes:connecting a first end of a mast to the envelope,connecting a second and of the mast to the space object, andextending a length of the mast. 13. A method according to claim 11, wherein controlling the deployment of the complete spatial separation between the envelope and the space object includesconnecting a first end of a tether to the envelope,connecting a second end of the tether to the space object, andextending a length of the tether. 14. A method according to claim 11, wherein controlling the inflating of the envelope includes constraining the envelope with a reefing system that encloses a portion of the envelope. 15. A method according to claim 8, wherein controlling the inflating of the envelope includes using a timer to begin the inflating of the envelope. 16. A method according to claim 15, wherein controlling the inflating of the envelope includes resetting the timer. 17. A method according to claim 8, further comprising: lowering the orbit of the space object to an altitude where a dynamic pressure is about 0.01 torr. 18. A method for lowering an orbit of a space object, comprising:connecting an envelope to the space object;controlling a deployment of a spatial separation between the envelope and the space object; andcontrolling an inflating of the envelope, whereincontrolling the inflating of the envelope includes constraining the envelope with a reefing system that encloses a portion of the envelope, andinflating the envelope increases an effective drag area of the envelope for increasing atmospheric drag on the envelope. 19. A method according to claim 18, wherein controlling the deployment of the spatial separation between the envelope and the space object includes:connecting a first end of a mast to the envelope,connecting a second end of the mast to the space object, andextending a length of the mast. 20. A method according to claim 18, wherein controlling the deployment of the spatial separation between the envelope and the space object includesconnecting a first end of a tether to the envelope,connecting a second end of the tether to the space object, andextending a length of the tether. 21. A method according to claim 18, wherein controlling the inflating of the envelope includes using a timer to begin the inflating of the envelope. 22. A method according to claim 18, wherein controlling the inflating of the envelope includes resetting the timer. 23. A method according to claim 18, further comprising: lowering the orbit of the space object to an altitude where a dynamic pressure is about 0.01 torr. 24. A method according to claim 18, wherein the reefing system includes a reefing sleeve.
