Brooks, the author of the determinedly straight-faced parody The Zombie Survival Guide (2003), returns in all seriousness to the zombie theme for his second outing, a future history in the style of Theodore Judson’s Fitzpatrick’s War. Although limited by its consumable resources in the same way as the Soviet Union’s first-generation Salyut stations, Skylab was much roomier and capable of more research. Skylab was 30.2 metres (99 feet) in length and 6.7 metres (22 feet) in diameter and had a mass of about 75,000 kg (165,000 pounds). As a first step toward establishing a long-term manned platform in space, Skylab made use of a Saturn V Moon rocket, whose third stage was outfitted with two decks as a habitat and ready-to-use orbital workshop, and the command and service modules of Apollo spacecraft, which ferried the station’s crews and small amounts of supplies. Moon landing program to a variety of scientific missions. Skylab was an outcome of the Apollo Applications Program set up by the National Aeronautics and Space Administration (NASA) in 1965 to adapt spacecraft and systems developed for the U.S. SpaceNext50 Britannica presents SpaceNext50, From the race to the Moon to space stewardship, we explore a wide range of subjects that feed our curiosity about space!.Learn about the major environmental problems facing our planet and what can be done about them!

The final manned period was from November 16, 1973, to February 8, 1974, when it was manned by the crew from the SL-4 mission (73-090A). Next, it was manned during the period July 28 to September 25, 1973, by the crew of the SL-3 mission (73-050A). It was first manned during the period May 25 to June 22, 1973, by the crew of the SL-2 mission (73-032A). The Skylab itself was launched on May 14, 1973. All parts were also capable of unmanned, in-orbit storage, reactivation, and reuse. It contained provisions and crew quarters necessary to support three-person crews for periods of up to 84 days each. The OWS was a modified Saturn 4B stage suitable for long duration manned habitation in orbit. The IU, which was used only during launch and the initial phases of operation, provided guidance and sequencing functions for the initial deployment of the ATM, solar arrays, etc. The AM provided an airlock between the MDA and the OWS, and contained controls and instrumentation. The MDA served as a dock for the command and service modules, which served as personnel taxis to the Skylab. The retrieval and installation of film used in the ATM was accomplished by astronauts during extravehicular activity (EVA). It was attached to the MDA and AM at one end of the OWS. The ATM was a solar observatory, and it provided attitude control and experiment pointing for the rest of the cluster. The Skylab was in the form of a cylinder, with the ATM being positioned 90 deg from the longitudinal axis after insertion into orbit. The Skylab (SL) was a manned, orbiting spacecraft composed of five parts, the Apollo telescope mount (ATM), the multiple docking adapter (MDA), the airlock module (AM), the instrument unit (IU), and the orbital workshop (OWS). ![]()
