This
1929 Hermann Noordung image depicts a three-unit space station as seen
from a space ship. Hermann Potocnik (1892-1929), also known as Herman Noordung,
created the first detailed technical drawings of a space station. The three
units were the habitat, the machine room, and the observatory, each connected
by an umbilical. The Earth is in the background, approximately 26,000 miles
away. The station in this image is roughly above Cameroon's southern tip,
in a geosynchronous orbit on the median of Berlin. (Credit: NASA.)
1929 Hermann Noordung depiction of a space station habitat wheel. Hermann Potocnik (1892-1929), also known as Herman Noordung, created the first detailed technical drawings of a space station. Power was generated by collecting sunlight through the concave mirror in the center. This was one of three components of Noordung's space station. The other two were the observatory and the machine room, each connected to the habitat by an umbilical. (Credit: NASA.) This
is an artist's impression of the "Brick Moon." "The Brick Moon" was the
title of an article published in the Atlantic Monthly by Edward Everett
Hale in 1869. This piece was the first known proposal for an Earth-orbiting
satellite. Hale envisioned that the satellite could be used by mariners
as a navigational aid. He believed it would be the longitudinal companion
to the latitudinal North Star. In 1869, this story was considered fantasy
but in retrospect "The Brick Moon" foreshadowed the need for a space station
and some of its technologies. (Credit: NASA.)

Unlike many other early space station concepts, this design actually made it out of the concept phase and into production, though no models were ever flown. This particular station was 30-feet and expandable. It was designed to be taken to outer space in a small package and then inflate in orbit. The station could, in theory, have been big enough for 1 to 2 people to use for a long period of time. A similar 24 foot station was built by the Goodyear Aircraft Corporation for NASA test use. The concept of space inflatables was revived in the 1990s. (Credit: NASA.) August

March 1, 1962: Vice President Lyndon B. Johnson pointed out areas in which international cooperation should begin in outer space. “As we attempt to look 25 years into the future, we catch visions of breathtaking journeys in large man-made planets around the sun to Mars and Venus-of a new freedom of movement of man across millions of miles of space -- of a permanent colony on the Moon and of large space stations or space forts at key locations for the conduct of space research, for aid to space navigation, and for rescue operations.” - Aeronautics and Astronautics, 1962, p. 36. April 28, 1962: First details of an orbital space station under feasibility study, one shaped like a doughnut and inflated once in orbit, revealed at Langley Research Center. Design of space stations had begun in November 1960 at Langley. Paul Hill, chief of the Appted Materials and Physics Division, stated that structures were now under study which could hold from four to thirty people. - Aeronautics and Astronautics, 1962, p. 64. August 2, 1962: First full-scale research model of an inflatable space station was displayed at NASA Lewis Research Center. Developed by Goodyear Aircraft Corp. for NASA, the doughnut-shaped, three-story-high structure was made of rubberized fabric and equipped to accommodate three to ten astronauts. - Aeronautics and Astronautics, 1962, p. 137. August 2-3, 1962: In meeting at NASA Langley Research Center, Langley and MSC personnel presented reports on space station studies to officials from NASA Headquarters. and other interested agencies. - Aeronautics and Astronautics, 1962, p. 138. September 12, 1962: NASA management meeting held to brief key officials on a manned space station program and to discuss possible FY 1964 funding. - Aeronautics and Astronautics, 1962, p. 181. During September 1962: Conclusion that wheel-shaped space station was technically feasible and identification of problems that still exist were revealed in NASA Technical Note D-1504, compilation of 11 papers by NASA Langley Research Center staff. Selection of this 45-m-diameter, 77.5-ton structure was result of studies by Langley for more than 2 years and detailed analyses by North American Aviation, Inc., for past 6 months. The report indicated the space station primarily would provide *a means of learning to live in space, where zero-gravity and variable-gravity experiments could be performed, closed life-support systems could be qualified, and rendezvous techniques and systems developed. Chosen model could support up to 38-man crew. Issue of ARS Astronautics contained series of articles by NASA Langley Research Center scientists and others, reviewing LaRC research program on manned space-station technology since early 1960. - Aeronautics and Astronautics, 1962, p. 203. November 16, 1962: Dr.
Hugh L. Dryden, NASA Deputy Administrator, said: “I personally believe
that the next large manned space flight project [after Apollo] will be
[a space station] rather than extensive exploitation of the Moon or manned
expeditions to the planets. This might change if the early lunar exploration
returned surprises in the form of natural resources of use on Earth. I
think it will now be appreciated that the present rather arbitrary subdivisions
of our program will coalesce, for the manned space station will be useful
for both manned and unmanned scientific exploration and could be the site
of observation of weather or of communications relay stations…”

February 7, 1963: Dr. James E. Roberts, USAF scientist, told that permanent five-man space station could be established “in the late 1965 or early 1966 time period.” Such a station, called “Mark I,”could be placed in orbit by Saturn I or Titan III vehicle, he said. Mark II station, three times as big as Mark I, could replace the initial station by the end of the decade. The space stations discussed by Dr. Roberts would be primarily for scientific and engineering research. - Aeronautical and Astronautical Events of 1963, p. 46. During February 1963: Four men spent 14 days in slow-rotation room simulating slowly-rotating space station, in NASA-sponsored experiment at Navy’s School of Aviation Medicine, Pensacola, Fla. ’No serious disturbance of a psychological or physiological nature was encountered,” and no change was found in conceptual reasoning, physical performance, perception, and sensory ability. No important changes in blood pressure, respiration, or pulse rate were observed during the experiment. - Aeronautical and Astronautical Events of 1963, p. 46. March 1, 1963: NASA Manned Spacecraft Center proposal to establish manned orbital space station which stressed that such a station and associated equipment could be established using rockets, equipment, and materials under development now for Project Apollo. Plan called for (1) orbiting space station with capacity for 18 crewmen; (2) sending six men in adapted Apllo-type spacecraft to board the orbiting station; and (3) sending two more such crews within a month of each other to staff the station, docking the shuttle spacecraft at the station’s three arms. Report said space station would be a national laboratory for study of space. - Aeronautical and Astronautical Events of 1963, p. 77-8. March 4, 1963: Dr. Hugh L. Dryden, NASA Deputy
Administrator, discussing studies of follow-on projects to manned lunar
landing, listed as “obvious candidates… establishment of a station on the
Moon permitting prolonged occupancy, a manned laborato orbiting the Earth
as a satellite, and manned reconnaissance of the planets…
April 15, 1963: Dr. Arthur R. Kantrowitz, Vice President of AVCO Corp., said: “I am one of those who favor, as our next objective, the permanent manned station in a low orbit around the Earth… It would give us a chance to learn to live and to work in space. It would give us a chance to achieve a larger vision of the potentialities of space… A laboratory like this would enlarge man’s horizons in an important way…” - Aeronautical and Astronautical Events of 1963, p. 142. April 18, 1963: Vice President and General Manager of Boeing Co. Aerospace Div., Lysle A. Wood, proposed:
April 24, 1963: NASA announced Langley Research Center had requested industry proposals for studying manned obital research laboratory systems capable of sustaining a four-man crew in space for one year. - Aeronautical and Astronautical Events of 1963, p. 158. During April 1963: NASA Manned Spacecraft Center issued requests for proposals for preliminary study contracts on (1) rotating manned space station to house 18 crewmen; (2) non-rotating, zero-gravity station to house 25-30 crewmen; (3) reusable logistics vehicle. - Aeronautical and Astronautical Events of 1963, p. 170. May 13, 1963: NASA was evaluating merits of manned space stations, permanent lunar bases and Mars expedition as follow-on to Project Apollo; technology needed for Mars spacecraft would be simpler in many ways than that required for lunar base or space station. - Aeronautical and Astronautical Events of 1963, p. 193. May 27, 1963: Proposed NASA-USN program of high-altitude, long-duration balloon flights was outlined. Pending DOD approval, program would call for three types of &ghts: three-man, three-day flight using basic gondola and existing balloon of 280 000 cubic meters class; 14-day flight, possiibly with larger crew and expanded equipment; and 30-day fllghts with six- or seven-man crew. Program objectives: to check out space station equipment and components and to study biomedical and psychological factors. - Aeronautical and Astronautical Events of 1963, p. 216. June 5, 1963: NASA announced selection of Boeing Co. and Douglas Aircraft Co. for final negotiations leading to manned orbital research laboratory study contracts. NASA Langley Research Center would negotiate definitive three-month study contracts with the two companies.- Aeronautical and Astronautical Events of 1963, p. 230. June 6-7, 1963: At a Symposium on exploration of Mars, A. James Shiner of NASA Man-System Integration delivered paper prepared by him and Dr. Eugene B. Konecci, Director of NASA Biotechnology and Human Research: “A manned orbital research laboratory… becomes a distinct requirement to obtain human design requirements for a Mars vehlcle system, whether that system is nuclear or chemical. The manned orbital research laboratory will help answer many of our questions about the environment, and man’s ability to not only survive, but to perform useful functions in prolonged acemissions. The mann orbital research laboratory under study by the Langley Research Center will have to operate for prolong periods of time to obtain the required human research and biotechnology data needed for design of advanced space systems. A manned orbital research laboratory will eventually used to simulate Martian voyages aa well….” - Aeronautical and Astronautical Events of 1963, p. 233. June 12, 1963: NASA Manned Spcecraft Center announced award of six-month study contract to Hamilton Standard Div. of United Aircraft Corp. for establishment of environmental control and life support requirements for manned Earth-orbiting space station. Duration of 24-man station would be from one to five years. - Aeronautical and Astronautical Events of 1963, p. 239. June 21, 1963: Dr. Floyd L. Thompson, Director of Langley Research Center, announced that whenever the U.S. decided to go ahead with a manned orbiting laboratory, Langley would be ready. “Although there is no NASA approved flight project for a manned space station at the present time, Langley will be in a position through its studies to provide many of the answers to design and operational problems when such a misson is given the go signal.” - Aeronautical and Astronautical Events of 1963, p. 251. July 4, 1963: NASA Manned Spacecraft Center announced two types of orbital manned space stations would be studied to compare concepts for 24-man operational station: one concept by Lockheed Co. California Div. and the other by Douglas Aircraft Missiles and Space Systems Div. Each station would be designed to remain in orbit at 300-500-kilometre altitude for about three yaars, with resupply and crew changes every three months. - Aeronautical and Astronautical Events of 1963, p. 266.

Experiment would begin in September. - Aeronautical and Astronautical Events of 1963, p. 269. July 16, 1963: Five men entered Boeing Co. space chamber, simulating quarters in manned space station or manned lunar base, for 30-day engineering test of integrated life-support system. Designed and built for NASA Office of Advanced Research and Technology, system included all elements of life support necessary for 150 man-day space mission. Associated with life-support equipment were specific crew tests simulating problems of space flight. Members of test crew: R. H. Lowry, Boeing Chief of Bioastronautics; Maj. Edward Westlake (CSAF) of Air Force Systems Cmd.; Roger Barnicki, NASA Flight Research Center X-15 personnel equipment specialist; Charles Proctor, Boeing biochemist and food specialist; and Richard Farrell, Boeing psychologist. - Aeronautical and Astronautical Events of 1963, p. 275. July 20, 1963: Five men locked in Boeing Co. test chamber on simulated 30-day space mission were forced to cut the test short after 104 hrs. [4.3 days] because hole developed in reactor tank (comparable to septic tank). - Aeronautical and Astronautical Events of 1963, p. 280. August 7, 1963: Under Secretary of the Air Force Brockway McMillan said: “We view a space station as an essential preliminary to an operational space defense system, and as a valuable source of experience which will apply to NASA objectives. As this program is in the early conceptual phase, we think it possible to begin now to fully exploit its high potential to serve both civilian and military needs. As you know, the Defense Department has proposed to NASA that there be collaboration in studies leading to the definition of the space station program…” - Aeronautical and Astronautical Events of 1963, p. 301-2. August 18, 1963: Under questioning by the House
Appropriations Subcommittee on Independent Offices, NASA Deputy Administrator
Dr. Hugh L. Dryden discussed the future space programs to follow the manned
lunar landing program: “There are three principal
candidates for what might be called the next program. These are the manned
orbital laboratory; the further exploration of the Moon; and finally, man’s
interplanetary travel.
September 20, 1963: NASA has been spending about $3 million a year on conceptual and design studies for a four- to six-man space laboratory orbiting some 500 kilometres above the Earth. From 1959 until last year, the Air Force spent about $10 million a year on design studies. These studies were halted largely because of skepticism within the Defense Department about a military role for man in space. Now it has been agreed that there should be closer coordination of the Air Force and NASA studies. Out of them, it now is hoped, will come a single project, National Orbital Space Station, or NOSS. Significantly, the Air Force has dropped its MODS (for Military Orbital Development Station) designation for its studies and is using NOES. - The New York Times, 20 September 1963. October 17, 1963: NASA and DOD announced joint agreement to coordinate studies and actions concerning a manned orbital research and develoment station. The Aeronautics and Astronautics Coordinating Board (AAOB) would be the means by which the joint appraisals would be carried out. If the eventual fidings were that such a program was required, the NASA Administrator and the Secretary of Defense would submit a joint recommendation to the President, includmg a statement as to which agency should have project responsibility. If the President agreed to proceed with the pmgram, a joint NASA-DOD hoard would be set up to establish objectives and approve specific experiments - Aeronautical and Astronautical Events of 1963, p. 392. December 2, 1963: NASA selected Douglas Aircraft Co. for negotiations leading to follow-on study contract for refinement and evaluation o! NASA manned orbital laboratory concept. Awarded on basis of Douglas performance of previous three-month study, the six-to-nine-month follow-on contract called for refining the NASA concept of a manned orbiting laboratory based on cylindrical six-man spacecraft. - Aeronautical and Astronautical Events of 1963, p. 459. December 10, 1963:
Cancellation of USAF Dyna Soar (X-20) manned aero spacecraft project announced
by Secretary of Defense Robert S. McNamara. Some of the funds saved would
be diverted into broader, long-range exploration of the problems and potential
of manned military operations in near space, chief project of which would
be Manned Orbiting Laboratory (MOL). Attached to modified Gemini spacecraft
(Gemini-X), MOL will be launched into orbit by Titan III launch vehicle,
the two-man Gemini crew then transferring to the house-trailer-sized MOL
where they will conduct experiments and observations for two to four weeks,
then return to Earth in the Gemini-X spacecraft. Schedule called for launching
late in 1967 or early in 1968. [...] NASA Assistant Administrator for Public
Affairs Julian Scheer said: “The decisions announced by Secretary McNamara
today with respect to the Dyna Soar Project and Manned Orbital Lab. followed
discussions with NASA and were fully coordinated with the programs of this
agency. The decisions announced by Secretary McNamara are based on the
best uses of resources to maximize our national capacity in space and NASA
fully supports them.” -

orbit and launch facility. It was to use a nuclear SNAP-II nuclear power
supply on the end of the long telescoping boom. Nuclear reactors were considered
dangerous, which is why in this concept drawing it was located so far away
from the habitat part of the station. Creators envisioned the structure
being built in orbit to allow assembly of the station in orbit which could
be then larger than anything that could be launched from Earth. The two
main modules were to be 33 feet in diameter and 40 feet in length. When
combined the modules would create a four deck facility, 2 decks to be used
for laboratory space and 2 decks for operations and living quarters. The
facility also allowed for servicing and launch of a space vehicle. Though
the station was designed to operate in micro- gravity, it would also have
an artificial gravity capability. (Credit:

January 1, 1964: NASA
position paper on DOD’s Manned Orbiting Laboratory, embodying eight principles
of NASA policy toward the MOL, was made public. The paper stated: “The
DOD Manned Orbital Laboratory is a single military project (a specific
goal; not a broad program) within the overall National Space Program.…
January 8, 1964: Edward Z. Gray, Director of Advanced Studies in NASA Office of Manned Space Flight, said that when NASA builds a manned space station it would be “more sophisticated” than the DOD Manned Orbiting Laboratory (MOL). NASA now has 13 studies dealing with concepts leading toward development of an orbiting manned space station; when these studies are completed, NASA would be able to appraise “the space station requirements and what will be the best method of pursuing the development of a manned orbiting space station system.” - Aeronautical and Astronautical Events of 1964, p. 8. January 11, 1964: James
J. Haggerty, Jr., predicted that assignment of Manned Orbiting Laboratory
to DOD was “an ominous harbinger of a reversal in trend, an indication
that the military services may play a more prominent role in future space
exploration at NASA’s expense.…
February 3, 1964: “The Manned Orbiting Laboratory (MOL) program, which replaced the Dyna-Soar, is a research program aimed at giving man the opportunity to operate in space so that we may determine whether and when the manned space vehicle will be militarily significant, reports Secretary of the Air Force Eugene M. Zuckert. The MOL program will provide much of the supporting knowledge for indicated future manned space systems. The timing of the program is based upon a technical decision that our primary need is to know what functions man can perform in orbit, before exploring, as completely as Dyna-Soar would have, the problems and techniques of controlled reentry. This latter will now be studied on a more limited developmental basis.” - Aeronautical and Astronautical Events of 1964, p. 44. February 5, 1964: Lt. Col. Robert S. Buchanan (USAF) of Aerospace Research Pilots School, Edwards AFB, told that the greatest potential dangers to large scientific space station with crew of 15 or more men would be fire and collision with a meteoroid or space debris. Studies were considering possibility of separating space stations into individual compartments that could be sealed off in case of catastrophes such as fire. - Aeronautical and Astronautical Events of 1964, p. 52. February 26, 1964: Lokheed-California Co. released details of its recommendations to NASA Manned Spacecraft Center on a scientific space station program. Lockheed study concluded manned station with crew of 24 could be orbiting the earth in 1968. Total cost of program -- including logistics spacecraft and ground support -- for five years’ operation was estimated at $2.6 billion. Study recommended launching the unmanned station into orbit with a Saturn V launch vehicle, then launching manned logistics vehicle to rendezvous and dock at the station. - Aeronautical and Astronautical Events of 1964, p. 80. March 2, 1964: NASA and DOD established the National Space Station Planning Sub-Panel of the NASA-DOD Aeronautics and Astronautics Coordinating Board (AACB), charged with studying and then making recommendations to AACB on the best configuration for follow-on manned space station to the MOL. Go-chairmen were Dr. Michael I. Yarymovych of NASA Advanced Manned Missions Office and Col. Kenneth Schultz, Deputy Director of Development Planning for Space, Hq. USAF. - Aeronautical and Astronautical Events of 1964, p. 90. March 3, 1964: Douglas Aircraft Co. was awarded follow-on study contract for Manned Orbital Research Laboratory by NASA Langley Research Center, to refine the NASA concept and examine the feasability of cylindrical six-man space station using equipment providing intermittent artificial gravity. Selection of Douglas for contract negotiation was announced last December. - Aeronautical and Astronautical Events of 1964, p. 92. March 4, 1964: USAF planned to launch six manned orbiting laboratories (MOL) over an 18-month period, beginning in late 1967 or early 1968, unnamed sources revealed in Washington. - Aeronautical and Astronautical Events of 1964, p. 96. During March 1964: NASA Manned Spacecraft Center received design recommendations for 24-man Large Orbital Research Laboratory (LORL) that could be operational by 1968 -- the six-month study conducted by Douglas Aircraft’s Missile & Space Div. and IBM’s Federal Systems Div. The cylindrical space station would operate under zero gravity conditions in a 400-km-high orbit. - Aeronautical and Astronautical Events of 1964, p. 121. April 15, 1964: Large manned space station design was described by Edward H. Olling, head of MSC Space Station Program Office. The 24-man station would be 45-metre in diameter with three radial modules, rotate at maximum speed of 4 rpm. Lifetime would be from one to five years. Saturn V could launch it into orbit and Saturn IB would launch logistics vehicles. - Aeronautical and Astronautical Events of 1964, p. 140. April 22, 1964:
Michael I. Yarymovych, Director of NASA Manned Earth Orbital Mission Studies,
said before Canaveral Council of Technical Studies, Cape Kennedy, that
NASA was coordinating fully with DOD in exploring four different types
of orbital systems: Extended Apollo, Apollo Orbital Research Laboratory
(AORL), Medium Orbital Research Laboratory (MORL), and Large Orbital Research
Laboratory (LORL). The first three concepts were designed to be orbited
by Saturn IB; LORL, by Saturn V. Yarymovych said that it was “becoming
increasingly clear that the Extended Apollo is an essential element of
an expanding Earth orbital program.…

January 21-22, 1971: Mockup of 12-man space station concept being studied by McDonnell Douglas Astronautics Co. for NASA was inspected by 100 Government and industry representatives attending quarterly review at Marshall Space Flight Center. Mockup was 10 metres in diameter and 15 metres tall, with four decks and large simulated power section. Concept called for tunnel section in center with 3-metre diameter. - Astronautics And Aeronautics, 1971, p. 10-1. This
is an illustration of the Space Base concept. In-house work of the Marshall
Space Flight Center, as well as a Phase B contract with the McDornel Douglas
Astronautics Company, resulted in a preliminary design for a space station
in 1969 and l970. The Marshall-McDonnel Douglas approach envisioned
the use of two common modules as the core configuration of a 12-man space
station. Each common module was 33 feet in diameter and 40 feet in length
and provided the building blocks, not only for the space station, but also
for a 50-man space base. Coupled together, the two modules would form a
four-deck facility: two

this station was designed to use Space Shuttle hardware. A solar array
was to be unwound from the exhausted main fuel tank. The structure could
then be formed and assembled in one operation. The main engine tank would
then be used as a space operations control center, a Shuttle astronaut
crew habitat, and a space operations focal point for missions to the Moon
and Mars. Credit: NASA.)

to build Space Station in Neutral Buoyancy Simulator (NBS) at Marshall
Space Center (MSFC)in 1985, early in the Space Station program. NASA began
operating the NBS at MSFC in 1968. The NBS provided an excellent weightlessness
environment to astronauts and engineers for testing hardware designed to
operate in space while also affording the opportunity to evaluate techniques
that were used in space to assemble structures such as Skylab, Hubble Space
Telescope and the International Space Station. The NBS tank is 75 feet
in diameter, 40 feet deep, and contains 1.3 million gallons of water, and
can accommodates structures as large as the 43-foot Hubble Space Telescope
mockup. Engineers direct NBS activities from a state-of-the-art control
room located on the first floor adjacent to the tank. (Credit: NASA.)
A 1969 station concept. The station was to rotate on its central axis to produce artificial gravity. The majority of early space station concepts created artificial gravity one way or another in order to simulate a more natural or familiar environment for the health of the astronauts. After returning micro-gravity environment, astronauts find their muscles weak because they have not been using them. Long-term exposure to micro-gravity could generate long-term health problems for astronauts who do not utilize their muscles. This is why there are exercise machines on space shuttles and on the International Space Station. It was to be assembled on-orbit from spent Apollo program stages. (Credit: NASA.)

A concept drawing of Space Station Freedom. Freedom was to be a permanently crewed orbiting base in orbit to be completed in the mid 1990's. It was to have a crew of 4. Freedom was an attempt at international cooperation that attempted to incorporate the technological and economic assistance, of the United States, Canada, Japan, and nine European nations. The image shows four pressurized modules (three laboratories and a habitat module) and six large solar arrays which were expected to generate 56,000 watts of electricity for both scientific experiments and the daily operation of the station. Space Station Freedom never came to fruition. Instead, in 1993, the original partners, as well as Russia, pooled their resources to create the International Space Station. (Credit: NASA.)
