A balloon is provided having a balloon envelope having a top portion and a bottom portion, a payload positioned beneath the balloon envelope, a moveable plate positioned atop the balloon envelope, a line attached to the moveable plate, and a control system configured to cause the line to be pulled to cause the moveable plate to be pulled towards the bottom portion of the balloon envelope such that the top portion of the balloon envelope is moved towards the bottom portion of the balloon envelope forcing gas out of the balloon envelope such that the balloon envelope is collapsed. The balloon may further include a drag plate positioned beneath the balloon envelope that serves to slow the descent of the payload to the earth.

1. A balloon, comprising: a balloon envelope having a top portion and a bottom portion;a payload positioned beneath the balloon envelope;a moveable plate positioned over the top portion of the balloon envelope;a line attached to the moveable plate;a control system configured to cause the line to be pulled to cause the moveable plate to be pulled towards the bottom portion of the balloon envelope such that the top portion of the balloon envelope is moved towards the bottom portion of the balloon envelope forcing gas out of the balloon envelope, such that the balloon envelope is collapsed. 2. The balloon of claim 1, wherein the collapsed balloon envelope remains positioned between the moveable plate and the payload during balloon descent. 3. The balloon of claim 1, wherein the moveable plate may be held in place or released by an actuator positioned on the balloon envelope. 4. The balloon of claim 3, wherein the actuator may be controlled wirelessly via a control system that is located in the envelope itself or located in or near the payload. 5. The balloon of claim 1, further including a drag plate positioned beneath the balloon envelope, wherein the drag plate serves to slow the descent of the payload to the earth. 6. The balloon of claim 5, wherein the line is pulled through the drag plate towards the payload to cause the balloon envelope to be collapsed between the moveable plate and the drag plate. 7. The balloon of claim 5, wherein the balloon envelope is attached to the drag plate by a tether. 8. The balloon of claim 1, wherein the payload is tethered to the moveable plate by the line. 9. The balloon of claim 5, wherein the drag plate is attached to the bottom portion of the balloon envelope and the payload is suspended from the line that passes through the drag plate. 10. The balloon of claim 5, wherein an outer surface of the drag plate extends as far as the diameter of the balloon envelope when the balloon envelope is inflated. 11. The balloon of claim 10, the outer surface of the drag plate extends beyond the diameter of the balloon envelope when the balloon envelope is inflated. 12. The balloon of claim 5, wherein the drag plate comprises a downward-facing concave plate. 13. The balloon of claim 5, wherein the drag plate comprises an upward-facing concave plate. 14. A computer-implemented method, comprising: operating a control system for a balloon comprised of a balloon envelope having a top portion and a bottom portion positioned beneath the top portion, a payload positioned beneath the balloon envelope, a moveable plate positioned atop the balloon envelope, and a line attached to the moveable plate to cause the moveable plate positioned atop the balloon envelope to be pulled towards the bottom portion of the balloon envelope;causing the top of the balloon envelope to be moved towards the bottom portion of the balloon envelope forcing gas out of the balloon envelope to collapse the balloon envelope; andmaintaining the collapsed balloon envelope beneath the moveable plate during balloon descent. 15. The method of claim 14, further including the step of using an actuator positioned on the balloon envelope to release the moveable plate to allow it to be pulled towards the bottom portion of the balloon envelope. 16. The method of claim 14, wherein the balloon further includes a drag plate positioned beneath the balloon envelope. 17. The method of claim 16, further including the step of pulling the line through the drag plate towards the payload to cause the balloon envelope to be collapsed between the moveable plate and the drag plate. 18. The method of claim 17, wherein the payload is tethered to the moveable plate by the line. 19. The method of claim 16, wherein an outer surface of the drag plate extends as far as the diameter of the balloon envelope when the balloon envelope is inflated. 20. The method of claim 19, wherein the outer surface of the drag plate extends beyond the diameter of the balloon envelope when the balloon envelope is inflated. 21. The method of claim 16, wherein the drag plate comprises a concave plate. 22. A non-transitory computer readable medium having stored therein instructions executable by a computing device to cause the computing device to perform functions comprising: operating a control system for a balloon comprised of a balloon envelope having a top portion and a bottom portion positioned beneath the top portion, a payload positioned beneath the balloon envelope, a moveable plate positioned atop the balloon envelope, and a line attached to the moveable plate to cause the moveable plate positioned atop the balloon envelope to be pulled towards the bottom portion of the balloon envelope;causing the top portion of the balloon envelope to be moved towards the bottom portion of the balloon envelope forcing gas out of the balloon envelope to collapse the balloon envelope; andmaintaining the collapsed balloon envelope beneath the moveable plate during balloon descent. 23. The non-transitory computer readable medium of claim 22, further including the function of using an actuator positioned on the balloon envelope to release the moveable plate to allow it to be pulled towards the bottom portion of the balloon envelope. 24. The non-transitory computer readable medium of claim 22, wherein the balloon further includes a drag plate positioned beneath the balloon envelope. 25. The non-transitory computer readable medium of claim 24, further including the function of pulling the line through the drag plate towards the payload to cause the balloon envelope to be collapsed between the moveable plate and the drag plate. 26. The non-transitory computer readable medium of claim 24, wherein an outer surface of the drag plate extends as far as the diameter of the balloon envelope when the balloon envelope is inflated. 27. The non-transitory computer readable medium of claim 26, wherein the outer surface of the drag plate extends beyond the diameter of the balloon envelope when the balloon envelope is inflated.
