Types of Space Habitats
O’Neil Cylinder Lewis One
Two counter-rotating cylinders each five miles (8 km) in diameter, and capable of scaling up to twenty miles (32 km) long.[5] Each cylinder has six equal-area stripes that run the length of the cylinder; three are windows, three are "land". Furthermore, an outer agriculture ring, as seen in the picture on the right, 10 miles (16 km) in radius, rotates at a differ-ent speed for farming. The manufacturing block is located at the middle (behind the satellite dish assembly) to allow for minimized gravity for some manufacturing processes.
The Lewis One space colony design is intended to improve on the 10,000 inhabitant designs of the mid-70s. The new design features large shielded micro-g construction bays, low-g agriculture near the rotation axis to reduce the length of cylindrical colonies, large micro-g visitor and recreation areas, space viewing, and low-g recreation.
Types of Space Habitats
Kalpana One Beaded Habitats
BoloThe Kalpana One structure is a cylinder with a radius of 250m and a length of 550m and is designed to house 5000 people. The size is determined by the limited rotation rate humans are assumed to tolerate, 2rpm. The rotation rate drives the radius to achieve 1g pseudo-gravity, and the radius drives the length due to angular moment of inertia requirements. For later, larger colonies in the Kalpana family, the rotation rate may be reduced, increasing the radius and the allowable length.
Orbital hotelTranshab was a concept pursued by NASA to develop the technology for expandable habitats inflated by air in space. Specifically, Transhab was intended as a replacement for the already existing rigid Inter-national Space Station crew habitation Module. When deflated, inflatable modules provide an easier to launch compact form.
Inside/Outside concept, was originated in 1964 by Dandridge M. Cole and Donald W. Cox in a nonfiction book called Islands in Space: The Challenge of the Planetoids.
