Aquarius (rocket)
Aquarius was a low-cost launch vehicle concept designed by Space Systems/Loral to carry small, inexpensive payloads into LEO.
==Concept==
The vehicle was primarily intended for launching bulk products, like water, fuel, and other consumables, that are inexpensive to replace in the event of a launch failure. The target launch cost was $1 million. Aquarius was designed to be a single-stage vehicle 43 meters (141 ft) high and 4 meters (13.1 ft) in diameter and powered by a single pressure fed engine using liquid hydrogen and oxygen propellants stored in a composite pressure tank.〔(【引用サイトリンク】 title=aquarius )〕 Launch would have taken place from a floating position in the ocean to minimize launch infrastructure with the ability to place a 1,000-kilogram (2,200 lb) payload into a , 52-degree orbit. The payload, located in the base of the vehicle, would be extracted by an orbiting space tug for transfer to its ultimate destination, like the ISS or a propellant depot, after which the vehicle would de-orbit and be destroyed.
