Part # 7: Payload, or cargo or space travel vehicle or rocket or satellites which are meant to dropped or delivered in space. Principle behind the construction and operation of this vehicle: (Part #2) Huge hollow stable structures are built strong enough to withstand sea level atmospheric pressure. And all the air from it is be pumped out. These hollow structures are designed in spherical shape, as, spheres are the only shapes whose surface area and volume ratio is the least when compared with other shapes. So, least consumption of material and maximum volume of air that can be removed is achieved. The weight of the air is approximately 1.2 kg / cubic meter, So, the total weight of material used to construct the hollow stable structure used is very much less than the weight of the volume of air pumped out of the structure. In that situation the hollow structure will float in the air. The total material weight of the hollow structure with no air in it should be < (the weight of the volume of air pumped out + the payload). At that stage this sphere will automatically ascend into space as per Archimedes principle. The construction of these huge hollow stable structure is done by means of block of very light weight material.

However, bringing back this sphere safely back to earth on its designated location would not be easy. In order to address this issue, a huge structure of light weight material is constructed (Part# 3) connecting many such hollow structures to achieve more weight lifting capacity, and control of its pressure. The main purpose of this structure is to: 1. Hold together all the individual spherical structures together 2. To bring back all the sphere to earth 3. To increase the payload capacity to a much higher fold, All spherical structures (Part# 2) are connected in a huge ring shaped structure (Part# 3) whose diameter can be imagined to be around 3 of a km or so. In this way, many such spherical structures are connected and controlled through a huge ring and control the air pressure of the sphere through the ring structure, a pilot cabin(Part# 5). This cabin is constructed to withstand conditions of different altitude of atmosphere and the conditions of space. (Part# 4) is a onboard air compressor and monitor & control system. (Part# 6) is a propeller to do little navigation of the entire system once back into atmosphere and closer to ground. In this way the system can be reused again and again to go and come back from space. Operation: On the ground these hollow spherical structures (Part# 2) are vacuumed to get a lift off. Once on the atmosphere or in space reaching a suitable height, the payload or satellite or space vehicle or rocket is released to navigate itself by its own propulsion system. Using the onboard booster (Part # 1). The vehicle is guided back to earth's atmosphere by the pilot onboard (Part #5) if its drifted into space. Once in atmosphere the spherical structures are refilled with air slowly to make a slow descend down to earth due to the weight of the air in it. The speed of the vehicle is controlled by the pumping out air from the spherical structures by the onboard compressor unit (Part # 4). Free fall into earth due to gravity is thus avoided to prevent air friction. The speed of the entire system can be controlled by the pilot using air compressor to do slow descend. Once close enough to ground using propellers (Part # 6) vehicle is landed to its required base. Conclusion: A huge cost of burning expensive rocket fuel to get upward is thus avoided by using this vehicle. The vehicle is reusable and safe.

Claims (4)

1. Reusable delivery vehicle to deliver rockets, or satellites or cargo payloads or space travel vehicles to space or atmosphere by using a collection of hollow stable structures which weigh lesser than the air they can contain by means of very low pressure to nil pressure, manoeuvred by manned/ controlled rocket or propulsion system to drop satellites/ rockets/ payloads /space travel vehicle in to space.

2. Achievement of upward lift and weight lifting capacity by means of single or multiple huge hollow stable structures emptied of its air to vacuum and its air pressure controlled. Huge hollow stable structures are constructed with very light weight material and the structure is air proof.

3. Re-entry of the vehicle into earth's atmosphere by means onboard rocket boosters after the delivery mission by the pilot. And slow descend to earth by means of filling hollow stable structures with air to make a slower descend to avoid free fall upon re-entry into atmosphere, by means of controlling pressure inside the structures.

4. Upon re-entry into lower altitude, manoeuvring of vehicle using onboard propeller system operated by the pilot to its destination safely.
