A method and apparatus for deploying a space structure. The space structure is secured to a base with release mechanisms that engage features of the space structure when the base is in a first position. The base is moved from the first position to a second position to deploy the space structure. The release mechanisms are moved at substantially a same time to disengage from the features and release the space structure from the base without imparting a transverse load to the space structure when the base moves from the first position towards the second position to deploy the space structure.

1. An apparatus comprising: a base that is moveable; andrelease mechanisms associated with the base, wherein the release mechanisms engage features of a space structure to secure the space structure to the base when the base is in a first position and the release mechanisms move at substantially a same time to disengage from the features and release the space structure from the base during acceleration without imparting a transverse load to the space structure, the release mechanisms including:a lever that has a closed position to secure one of the features and the space structure, and rotates to an open position in a manner that allows the feature and space structure to move, wherein an elongate structure extending from a surface of a housing holds the lever in the closed position and wherein when the lever rotates from the closed position to an open position the lever does not contact the feature or other portions of the space structure when the space structure moves within the housing, to thereby reduce transverse loads during movement of the base to deploy the space structure. 2. The apparatus of claim 1 further comprising: a biasing system that moves the base from the first position to the second position. 3. The apparatus of claim 1 further comprising: the housing having an opening, wherein the base and the release mechanisms are located within the housing and wherein the space structure is located inside the housing when the space structure is secured to the base; anda door that moves between a closed position and an open position and covers the opening when in the closed position. 4. The apparatus of claim 3 further comprising: a vibration reduction structure associated with the door, wherein the vibration reduction structure contacts the space structure such that vibrations in the space structure are reduced when the space structure is secured to the base by the release mechanisms and the door is in the closed position. 5. The apparatus of claim 4 further comprising: a locking system that holds the base in the first position when the door is in the closed position. 6. The apparatus of claim 1, wherein the release mechanisms are in closed positions when the base is in the first position and move at substantially the same time to open positions to release the space structure from the base without imparting the transverse load to the space structure when the base moves from the first position towards the second position to deploy the space structure. 7. The apparatus of claim 1 further comprising: a retaining system that prevents the release mechanisms from moving to release the space structure when the base is in the first position. 8. The apparatus of claim 1, wherein a release mechanism in the release mechanisms comprises: a contact point associated with the base, wherein the contact point supports a feature on the space structure;the lever secures the feature to the contact point when the lever is in a closed position; anda biasing device that moves the lever from the closed position to an open position when the base moves from the first position towards the second position such that the feature disengages from the contact point. 9. The apparatus of claim 8, wherein the contact point comprises: the structure extending from a surface of the base and having a shape that engages the feature on the space structure. 10. The apparatus of claim 1, wherein the release mechanisms comprise: three release mechanisms. 11. The apparatus of claim 1, wherein at least one of tumbling of the space structure or shock applied to the space structure is reduced when the space structure is deployed. 12. The apparatus of claim 1, wherein the space structure is selected from one of a satellite, a space station, and a spacecraft. 13. A method for deploying a space structure, the method comprising: securing the space structure to a base with release mechanisms that engage features of the space structure when the base is in a first position;moving the base from the first position to a second position to deploy the space structure; andmoving the release mechanisms at substantially a same time to disengage from the features and release the space structure from the base without imparting a transverse load to the space structure when the base moves from the first position towards the second position to deploy the space structure, wherein the release mechanisms include a lever that has a closed position to secure one of the features and the space structure, which rotates to an open position in a manner that allows the feature and space structure to move, andwherein an elongate structure extending from a surface of a housing holds the lever in the closed position and moving the release mechanisms comprises rotating the lever from the closed position to an open position in which the lever does not contact the feature or other portions of the space structure when the space structure moves within the housing, to thereby reduce transverse loads during movement of the base to deploy the space structure. 14. The method of claim 13, wherein the base and the space structure are located in the housing when the base is in the first position and further comprising: opening a door for the housing to expose an opening in the housing for deploying the space structure from the housing, wherein the space structure moves out of the housing through the opening when the base moves from the first position to the second position. 15. The method of claim 14 further comprising: contacting the space structure with a vibration reduction structure associated with the door in the housing in which the space structure is located, wherein the vibration reduction structure reduces vibrations in the space structure when the door is closed. 16. The method of claim 14, wherein moving the base comprises: moving the base from the first position to the second position with a biasing system after the door opens. 17. The method of claim 13, wherein the level is a lever in a plurality of levers, wherein the space structure has features that are engaged with the release mechanisms when the base is in the first position, and wherein moving the release mechanisms comprises: rotating the levers in the release mechanisms from closed positions to open positions when the base moves from the first position towards the second position;applying an axial force, perpendicular to the base, to the space structure at features on the space structure engaged with contact points in the release mechanisms while the base moves from the first position towards the second position such that the space structure accelerates in a direction of the axial force when deploying the space structure; anddisengaging the features of the space structure from the contact points when at least one of decelerating of the base or reaching the second position by the base occurs. 18. The method of claim 17, wherein rotating the levers comprises: rotating the levers with biasing devices to move the release mechanisms from the closed positions to the open positions when the base moves from the first position towards the second position such that the levers no longer secure the features to the contact points. 19. The method of claim 13, wherein at least one of tumbling of the space structure or shock applied to the space structure is reduced when the space structure is deployed. 20. The method of claim 13, wherein the space structure is selected from one of a satellite, a space station, and a spacecraft.
