1. An apparatus comprising: a frame configured for a translation into a vehicle body;a door moveably connected to the frame by a first circular track system disposed at a first end of the door and a second circular track system disposed at a second end of the door, wherein the first circular track system and the second circular track system are configured to rotate about the frame from a closed position to an open position after the translation; anda door movement system configured to translate the door inwardly from a first position to a second position into the vehicle body and to rotate the door in the second position to the open position to provide access to an opening in a mold line of the vehicle body without moving the door outside of the mold line of the vehicle body, wherein the mold line is an exterior surface of the vehicle body, wherein in the closed position the door closes the opening, and wherein in the open position the door allows an interior space of the vehicle body to be in communication with an exterior environment of the vehicle body through the opening. 2. The apparatus of claim 1, wherein the door movement system is capable of translating the door from the second position to the first position after the door has been moved to provide the opening. 3. The apparatus of claim 1, further comprising: a motor capable of rotating the door. 4. The apparatus of claim 3, further comprising: a gear system connected to the motor and the door, wherein the gear system is capable of rotating the door about the frame in response to operating the motor. 5. The apparatus of claim 3 further comprising: a plurality of wheels attached to the frame, wherein the plurality of wheels engage the first track system and the second track system. 6. The apparatus of claim 5, wherein the motor is configured to rotate a wheel of the plurality of wheels to rotate the door between the open position and the closed position. 7. The apparatus of claim 1, wherein the frame is translated by a linear actuator system. 8. The apparatus of claim 1, wherein the vehicle body is for a vehicle selected from one of a mobile platform, an aircraft, a surface ship, a tank, a personnel carrier, a train, a spacecraft, a submarine, and a bus. 9. The apparatus of claim 1, wherein a number of seals are present around the opening, and wherein the door reduces a faying surface on the number of seals. 10. A door for an aircraft comprising: an aircraft body having an opening in an exterior surface of the aircraft body for placing an interior space of the aircraft in communication with an exterior environment of the aircraft;a frame attached to the aircraft body;a door moveably connected to the frame by a first circular track affixed to a first end of the door and a second circular track affixed to a second end of the door, wherein the first circular track and the second circular track, are configured to rotate the door about the frame between a closed position and an open position without moving the door outside of the exterior surface of the aircraft body, wherein in the closed position the door closes the opening and in the open position allows an interior space of the aircraft body to be in communication with an exterior environment of the aircraft body through the opening;a gear system connected to a motor; anda linear actuator system configured to translate the frame into the aircraft body before the door is rotated from the closed position to the open position by the gear system. 11. A method for moving a door, the method comprising: translating the door inward from a first position to a second position into a vehicle body;rotating the door in the second position to an open position, by a first circular track affixed to a first end of the door and a second circular track affixed to a second end of the door, wherein the first circular track and the second circular track are configured to translate with a frame and to rotate the door about the frame, wherein rotating the door is performed without moving the door outside of a mold line of the vehicle body, wherein the mold line is an exterior surface of the vehicle, and wherein in a closed position the door completely closes an opening in the mold line and in the open position allows an interior space of the vehicle body to be in communication with an exterior environment of the vehicle body through the opening; andtranslating the door from the second position to the first position. 12. A method for moving a door in an aircraft, the method comprising: configuring a first circular track affixed to a first end of the door and a second circular track affixed to a second end of the door to translate with a frame moveably affixed to the door and to rotate the door about the frame;translating the frame and the door inward from a first position to a second position into an aircraft body; andresponsive to translating the frame inward from the first position to the second position, rotating, by the first circular track and the second circular track, the door from a closed position to an open position to provide an opening in the aircraft body, wherein rotating the door is performed without moving the door outside of a mold line of the aircraft body, wherein the mold line is an exterior surface of the aircraft body, and wherein in the closed position the door seals and completely closes an opening in the mold line and in the open position allows an interior space of the aircraft body to be in communication with an exterior environment of the aircraft body through the opening.
