Former headquarters of the Justifiers.
Embassy Station is a (formerly) manned space station in a low Earth orbit that varies from 479 km (298 mi) to 520 km (324 mi) above the Earth's surface. The station travels at about 27,400 km/h (17,000 mi/h), making one complete revolution around the Earth in about 90 minutes.
Embassy Station was the headquarters of the Justifiers from 1979 until 1986. The station was originally intended as a permanently occupied "city in the sky" to serve as a launching point for future space exploration, and potentially as a welcome center for any visiting extraterrestrials. Construction of Embassy Station was performed by an international team of engineers and scientists, and funded by a joint partnership of the United Nations, several countries and space agencies, and a large number of philanthropic organizations. Construction of the station began in 1977, and was officially completed in 1982. In 1979, a UN resolution granted the ownership of Embassy Station to the Justifiers, making it the largest privately owned man-made object outside of the Earth.
Unfortunately, the cost to operate and maintain the station made extended habitation impractically expensive for ordinary citizens and business owners, and by 1984 the station was all but abandoned. The Justifiers continued to use the station as a base of operations, but transportation between the station and Earth was a perennial source of difficulty, and in 1986 the team returned to Earth. The Justifiers continued to use the station for research purposes and for storage of dangerous items captured from criminals.
Despite the apparent failure of Embassy Station as a manned space station, it served as an invaluable source of information about the construction and maintenance of large space structures. Construction of the International Space Station would not have been possible without the lessons learned from successes and failures of Embassy Station.
The primary means of transportation between the station and the earth was the Justifiers' Orion spaceplane.
