A method generates an operational ballistic capture transfer for an object emanating substantially at earth or earth orbit to arrive at the moon or moon orbit using a computer implemented process. The method includes the steps of entering parameters including velocity magnitude VE, flight path angle ηE, and implementing a forward targeting process by varying the velocity magnitude VE, and the flight path angle ηE for convergence of target variables at the moon. The target variables include radial distance, rM, and inclination iM. The method also includes the step of iterating the forward targeting process until sufficient convergence to obtain the operational ballistic capture transfer from the earth or the earth orbit to the moon or the moon orbit.

Orbital launch vehicles (1) with aerodynamic lifting surfaces (2) enabling them to be towed as gliders behind conventional aircraft (19), and the method of towing these launch vehicles using a flexible cable (18) to connect them with a conventional aircraft (19), for placing spacercraft (15) into low earth orbit at greatly reduced cost compared to current orbital launch systems. The lift from the aerodynamic surfaces (2) enables the launch vehicles (1) to be towed by means of a flexible cable (18) from a conventional runway using existing aircraft (19). As with "conventional air-lauch", this permits spacercraft launch into orbit to originate from any conventional runway consistent with constraints of public safety, thus eliminating the need to build dedicated launch pads at geographic locations from which a full range of orbital inclinations can be reached.

An apparatus and method for launching a spacecraft (200) including a payload (202) and a delivery stage (204) having a rocket engine (37) powered by fluid bipropellant (114) from the earth into a high energy orbit and for recovering the delivery stage (204). By reducing the delivery stage mass, it becomes feasible and cost effective to recover the delivery stage (204) for reuse. Delivery stage mass is reduced by several techniques including transporting the spacecraft (200) and the fluid bipropellant (114) to a parking orbit with the fluid bipropellant in tanks (20-26) external to the spacecraft (200); transferring the fluid bipropellant (114) to light weight tanks (30-36) integral to the spacecraft (200); controlling the relative flow rates of the fluid bipropellant constituents to the rocket engine (31) during firing of the rocket engine (37) to ensure complete use of both bipropellant constituents; and controlling ascent and descent maneuvers from remote tracking stations. A space shuttle (42) can be used to transport the spacecraft (200) and fluid bipropellant (114) in its cargo bay (40) to the parking orbit and recover the delivery stage (204) at the end of a mission. The invention is particularly useful for delivery of payloads to geosynchronous orbits.
