Abstract: A Spaceshuttle launched and rescued Double Observatory, similar in shape to the Spaceshuttle Launched Observatory, but there is a difference inside the core of the fuselage, for instead of accommodating a singular observatoy and telescope tube, the central fuel tank is sandviching a full length of a tubular body to the outer fuel tank on a way that the double mirrored observatory and its two secondaries are al pushed up to the nose-cone of the fuselage, and these ar pulled down into position by the outgoing central fuel tank, which finally pull the long tube out, observatory at the centre, that may erect two or more wing-like radiation collectors, while the Spaceshuttle could receive the central fue tank back and it could go back to Earth with its probably many space-passengers taking the observatory back to the earth later.

Abstract: A Spaceshuttle Double Observatory of a singular system, in which the spaceshuttle is a self-launching-lifting body, having a two-ringed fuselage, in which the inner or central fuel tank could move outwardly towards the tail, when empty, however this slipping movement could pull to the centre a two-sided, two main reflectors covered observatory, and as it goes out, still it pulls a second secondary reflector to the tail-end, leaving behind a large opening without the need for extra star-doors, while at the top-cone the originally fixed first secondary is opened out with star-doors, thus the two telescopes, opened to the two opposite ends, could introduce a new tipe of observational astronomy, which was unknown before, by which the centre of the Universe could be detected perhaps together with the life-generating regions, or the most effective implosion regions that supply the creation-fields.

Abstract: A Ground-effect Aircraft and Airfield, both for serving sea-sides located mass-transportation in a manner that this aircraft is alway flying very near to the sea-level and always landing on sea-side resources on its own specially designed framed sea-strip, inside which the water is always mirror smooth, having a wide span for carrying about 500 passengers in the wing, quickly removable from the long and wide double-bubble fuselage, the fuel-tank, whose nose has a canard wing, its tail has a big, singular, specially designed engine, quickly removeable from the main wing, which is very quickly refillable, having two stabilizer tail plains, each with two knife-edged fuselages, using inflatables for the quick lifting up of the wing in changing a new fuselage, making the flying capacity more economical, thus, while it is the wing which is the heart of the matter, it is served by twice as many fuselages.

Abstract: An Artificial Glaciation controlled lowering the level of the oceans by storing ice on the Arctic sea-ice with the help of the winds, first, by developing big ice-dams in the Arctic Straits for preventing the outward flow and for holding the stored ice firmly on the consolidated sea-ice, making it thicker and thicker gradually, directing the big Arctic rivers to the top of the sea-ice, later on allowing them to create their “tundra-land seas” with large open surface areas, allowing the uncooled Gulf Stream to penetrate to the Severnaya, with all of these causing the winds loaded, producing more precipitation, and gaining the lowering the level of the oceans with 1.5 cm/years, producing wide free continental shelves, making all the rivers energetically stronger, free from their old floods, but above all, saving mankind from its present run towards its self annihilation with the increased polar melting.

Abstract: A Spaceshuttle telescope-observatory as a singular system has a circularly cross-sectioned long fuselage of a closed tipe and an opening nozzle-cone at the top of a secondary reflector that serves the primary reflector on the top side of the telescope-observatory, while the main reflector and the observatory is located at the bottom part of the fuselage, having the wings, each operative with turbable tips for the collecting of solar radiation. This system have to be launched conventionally by a large lifting body.

Abstract: A Spaceshuttle Forked Observatory of a singular ultralight system, in which the Spaceshuttle is a self-lifting body, capable of doing reentry, together with its forked and base-rotated telescope and observatory when this latter part is closed into the nose-cone of a large fuselage, but in the working or space-conditions the fork could rotate in the fuselage, the telescope could rotate in the fork, and the frontal, as well as the back part of the telescope could be made longer telescopically, but not necessarily, and the opening star-doors of the telescope could save the frontal secondary with their outer ablation layers in reentry, in which a large frontal landing geer could be lowered before touch-down. Nothing is planned to be jettisoned. The telescope could be operative with a five meters wide main reflector, and the big Spaceshuttle could stay in space for a long time.

Abstract: A Spaceshuttle launched observatory is hidden in the fuselage of the shuttle in lift up at the top, but being a third tubular body, it is pulled out, as the large central fuel tank is slipping outwardly towards the tail, pulling down the secondary to the botton of the telescope tube, as the fuel tank goes, both the telescope-observatory and fuel tank of the central fuselage comes out, leaving the seemingly empty lift-up shuttle body, whose frontal fuselage could accommodate cockpits for a number of space travellers, interested about a few circlings and in the reentry, however, after a long time of refilling the same could be launched again with a new observatory and crew, and when these are positioned out, the shuttle could rescue the old observatory and bring it bach, making its new travellers richer with the experience of fishing back the old observatory.

Abstract: A Spaceshuttle Observatory of a singular system that creates its observatory in its fuselage telescopically on two possible ways, when the large body arrives to space, and the observatory is opened out (A) towards the tail, by leaving the observatory and its main reflector at the top-cone, and pulling the secondary reflector down, as the central tank is slipping out, or it is the secondary reflector which is fixed at the top inside a number of opened star-doors, and the downwardly slipping central fuel tank is pulling the main reflector with its observatory to the center of the fuselage, in this case with the possibility of saving the central tank and engine. In both cases there is a need for turning the wing tips towards the sun.
