The Earth Alliance has heavily colonized the Sol system as well as a variety of other worlds. By 2259 the Alliance had established more than two dozen outposts and colonies in fourteen different solar systems.1Circa sixty of them have been identified in Babylon 5 media so far. 2 1 Home System Colonies 2 Outer Colonies 3 Minor Colonies and Outposts 4 Beta Colonies 5 References Luna.
2042 – On behalf of several space agencies and asteroid mining companies Blue Origin's manned spaceship reaches Mars orbit near Phobos with first modules for Free Spaceport of Phobos project which will be a space station with several spinning sections with Mars-level artificial gravity of 0.38g and serve as a way station and fuel&repairs.
A space habitat (also called a space colony, space settlement, orbital habitat, orbital settlement or orbital colony) is more than a bare-bones space station, in that it is intended as a permanent settlement or green habitat rather than as a simple way-station or other specialized facility. No space habitat has been constructed yet, but many design concepts, with varying degrees of. The first spacecraft to travel from Earth to Jupiter was NASA’s Pioneer 10 probe, which launched on March 3rd, 1972, and reached the Jupiter system on December 3, 1973 – 640 days (1.75.

The Stanford torus is a proposed NASA design[1] for a space habitat capable of housing 10,000 to 140,000 permanent residents.[2]
The Stanford torus was proposed during the 1975 NASA Summer Study, conducted at Stanford University, with the purpose of exploring and speculating on designs for future space colonies[3] (Gerard O'Neill later proposed his Island One or Bernal sphere as an alternative to the torus[4]). 'Stanford torus' refers only to this particular version of the design, as the concept of a ring-shaped rotating space station was previously proposed by Wernher von Braun[5] and Herman Potočnik.[6]
It consists of a torus, or doughnut-shaped ring, that is 1.8 km in diameter (for the proposed 10,000 person habitat described in the 1975 Summer Study) and rotates once per minute to provide between 0.9g and 1.0g of artificial gravity on the inside of the outer ring via centrifugal force.[7]
Sunlight is provided to the interior of the torus by a system of mirrors, including a large non-rotating primary solar mirror.
The ring is connected to a hub via a number of 'spokes', which serve as conduits for people and materials travelling to and from the hub. Since the hub is at the rotational axis of the station, it experiences the least artificial gravity and is the easiest location for spacecraft to dock. Zero-gravity industry is performed in a non-rotating module attached to the hub's axis.[8]
The interior space of the torus itself is used as living space, and is large enough that a 'natural' environment can be simulated; the torus appears similar to a long, narrow, straight glacial valley whose ends curve upward and eventually meet overhead to form a complete circle. The population density is similar to a dense suburb, with part of the ring dedicated to agriculture and part to housing.[9]
Construction[edit]
The torus would require nearly 10 million tons of mass. Construction would use materials extracted from the Moon and sent to space using a mass driver. A mass catcher at L2 would collect the materials, transporting them to L5 where they could be processed in an industrial facility to construct the torus. Only materials that could not be obtained from the Moon would have to be imported from Earth. Asteroid mining is an alternative source of materials.[10]

This trainer +1 has been created by MrAntiFun for game version 0.711. All cheats on our site you can download without registration, so this hack available for download free. With this trainer you will get the advantage in your game. But first, a bit of information about the game.
Earth Space Colonies is a strategy-simulation game where you build space colonies around the Solar system. Your first destination is Mars. Establish a first self-sustaining colony and terraform a red wasteland into a green oasis. Balance your resources and expand the infrastructure. Build anything from high-tech factories, hotels, military bases to space elevators and terraformers. Colonize other worlds as well: defend a mining colony on a dwarf planet Ceres and explore the subsurface ocean on Ganymede, Jupiter’s largest moon.
