Stairway to Heaven? Geographies of the Space Elevator in Science Fiction
ISSN 2624-9081 • DOI 10.26034/roadsides-202000306 Stairway to Heaven? Geographies of the Space Elevator in Science Fiction Oliver Dunnett Outer space is often presented as a kind of universal global commons – a space for all humankind, against which the hopes and dreams of humanity have been projected. Yet, since the advent of spaceflight, it has become apparent that access to outer space has been limited, shaped and procured in certain ways. Geographical approaches to the study of outer space have started to interrogate the ways in which such inequalities have emerged and sustained themselves, across environmental, cultural and political registers. For example, recent studies have understood outer space as increasingly foreclosed by certain state and commercial actors (Beery 2012), have emphasised narratives of tropical difference in understanding geosynchronous equatorial satellite orbits (Dunnett 2019) and, more broadly, have conceptualised the Solar System as part of Earth’s environment (Degroot 2017). It is clear from this and related literature that various types of infrastructure have been a significant part of the uneven geographies of outer space, whether in terms of long-established spaceports (Redfield 2000), anticipatory infrastructures (Gorman 2009) or redundant space hardware orbiting Earth as debris (Klinger 2019). collection no. 003 • Infrastructure on/off Earth Roadsides Stairway to Heaven? 43 Having been the subject of speculation in both engineering and science-fictional discourses for many decades, the space elevator has more recently been promoted as a “revolutionary and efficient way to space for all humanity” (ISEC 2017). The concept involves a tether lowered from a position in geostationary orbit to a point on Earth’s equator, along which an elevator can ascend and arrive in orbit. -

The Space Elevator NIAC Phase II Final Report March 1, 2003
The Space Elevator NIAC Phase II Final Report March 1, 2003 Bradley C. Edwards, Ph.D. Eureka Scientific [email protected] The Space Elevator NIAC Phase II Final Report Executive Summary This document in combination with the book The Space Elevator (Edwards and Westling, 2003) summarizes the work done under a NASA Institute for Advanced Concepts Phase II grant to develop the space elevator. The effort was led by Bradley C. Edwards, Ph.D. and involved more than 20 institutions and 50 participants at some level. The objective of this program was to produce an initial design for a space elevator using current or near-term technology and evaluate the effort yet required prior to construction of the first space elevator. Prior to our effort little quantitative analysis had been completed on the space elevator concept. Our effort examined all aspects of the design, construction, deployment and operation of a space elevator. The studies were quantitative and detailed, highlighting problems and establishing solutions throughout. It was found that the space elevator could be constructed using existing technology with the exception of the high-strength material required. Our study has also found that the high-strength material required is currently under development and expected to be available in 2 years. Accepted estimates were that the space elevator could not be built for at least 300 years. Colleagues have stated that based on our effort an elevator could be operational in 30 to 50 years. Our estimate is that the space elevator could be operational in 15 years for $10B. In any case, our effort has enabled researchers and engineers to debate the possibility of a space elevator operating in 15 to 50 years rather than 300. -

Hoyt, Ph.D. ABSTRACT The Phase I effort developed a design for a space systems architecture for repeatedly transporting payloads between low Earth orbit and the surface of the moon without significant use of propellant. This architecture consists of one rotating tether in elliptical, equatorial Earth orbit and a second rotating tether in a circular low lunar orbit. The Earth-orbit tether picks up a payload from a circular low Earth orbit and tosses it into a minimal-energy lunar transfer orbit. When the payload arrives at the Moon, the lunar tether catches it and deposits it on the surface of the Moon. Simultaneously, the lunar tether picks up a lunar payload to be sent down to the Earth orbit tether. By transporting equal masses to and from the Moon, the orbital energy and momentum of the system can be conserved, eliminating the need for transfer propellant. Using currently available high-strength tether materials, this system could be built with a total mass of less than 28 times the mass of the payloads it can transport. -

Integrated Lunar Transportation System
Integrated Lunar Transportation System Jerome Pearson1, John C. Oldson2, Eugene M. Levin3, and Harry Wykes4 Star Technology and Research, Inc., Mount Pleasant, SC, 29466 An integrated transportation system is proposed from the lunar poles to Earth orbit, using solar-powered electric vehicles on lunar tramways, highways, and a lunar space elevator. The system could transport large amounts of lunar resources to Earth orbit for construction, radiation shielding, and propellant depots, and could supply lunar equatorial, polar, and mining bases with manufactured items. We present a system for lunar surface transport using “cars, trucks, and trains,” and the infrastructure of “roads, highways, and tramways,” connecting with the lunar space elevator for transport to Earth orbit. The Apollo Lunar Rovers demonstrated a battery- powered range of nearly 50 kilometers, but they also uncovered the problems of lunar dust. For building dustless highways, it appears particularly attractive to create paved roads by using microwaves to sinter lunar dust into a hard surface. For tramways, tall towers can support high- strength ribbons that carry cable cars over the lunar craters; the ribbon might even be fabricated from lunar materials. We address the power and energy storage requirements for lunar transportation vehicles, the design and effectiveness of lunar tramways, and the materials requirements for the support ribbons of lunar tramways and lunar space elevators. 1. Introduction NASA is implementing a plan for a return to the Moon, which will build on and expand the capabilities demonstrated during the Apollo landings. The plan includes long-duration lunar stays, lunar outposts and bases, and exploitation of lunar resources on the Moon and in Earth orbit1. -
Pathways to Colonization David V
Pathways To Colonization David V. Smitherman, Jr. NASA, Marshall Space F’light Center, Mail CoLFDO2, Huntsville, AL 35812,256-961-7585, Abstract. The steps required for space colonization are many to grow fiom our current 3-person International Space Station,now under construction, to an inhstmcture that can support hundreds and eventually thousands of people in space. This paper will summarize the author’s fmdings fiom numerous studies and workshops on related subjects and identify some of the critical next steps toward space colonization. Findings will be drawn from the author’s previous work on space colony design, space infirastructure workshops, and various studies that addressed space policy. In cmclusion, this paper will note that siBnifcant progress has been made on space facility construction through the International Space Station program, and that si&icant efforts are needed in the development of new reusable Earth to Orbit transportation systems. The next key steps will include reusable in space transportation systems supported by in space propellant depots, the continued development of inflatable habitat and space elevator technologies, and the resolution of policy issues that will establish a future vision for space development A PATH TO SPACE COLONIZATION In 1993, as part of the author’s duties as a space program planner at the NASA Marshall Space Flight Center, a lengthy timeline was begun to determine the approximate length of time it might take for humans to eventually leave this solar system and travel to the stars. The thought was that we would soon discover a blue planet around another star and would eventually seek to send a colony to explore and expand our presence in this galaxy. -
Space Elevator a New Way to Gain Orbit Adil Oubou 5/3/2014
Space Elevator A New Way To Gain Orbit Adil Oubou 5/3/2014 Abstract After 56 years of great space exploration, the space flight program found itself asking an intriguing question: What’s next? Should humans constrain the space program to low Earth orbit, revisit the moon, or simply go beyond anything they have done before? No matter what the next step is, there is a great need for a reliable, safe, affordable and easy method of gaining orbit. The space elevator concept discussed in this report, based on the design provided in Peter Swan’s book “Space Elevators: An Assessment of the Technological Feasibility and the Way Forward“, shines the light on an economically and technologically feasible solution within the next two decades that will lift payloads including humans from the earth’s surface into space at a greater capacity than current rockets while significantly lowering cost to $500/kg. The system design includes a tether line that extends from the Earth’s surface to an altitude of 100,000 km that utilizes electrical motor driven climbers to gain orbit. The success feasibility of this space flight system is highly dependent on the development of Carbon Nanotube (CNT) material, which will provide high strength and low mass properties for the space elevator system components to withstand environmental and operational stresses.

Technology Development and Demonstration Concepts for the Space Elevator
55th International Astronautical Congress 2004 - Vancouver, Canada IAC-04-IAA.3.8.3.02 TECHNOLOGY DEVELOPMENT AND DEMONSTRATION CONCEPTS FOR THE SPACE ELEVATOR David V. Smitherman, Jr., Architect Technical Manager, Advanced Projects Office NASA Marshall Space Flight Center, Huntsville, Alabama, USA E-mail: [email protected] ABSTRACT In 1999, the author managed for the National Aeronautics and Space Administration (NASA), a space elevator workshop at the NASA Marshall Space Flight Center to explore the potential feasibility of space elevators in the 21st century, and to identify the critical technologies and demonstration missions needed to make the development of space elevators feasible. Since that time, a NASA Institute for Advanced Concepts (NIAC) funded study proposed a simpler concept for the first space elevator system using more near-term technologies. This paper will review some of the latest ideas for space elevator development, the critical technologies required, and some of the ideas proposed for demonstrating the feasibility for full-scale development of an Earth to Geostationary Earth Orbit (GEO) Space Elevator. In conclusion, this paper finds that the most critical technologies for an earth-based space elevator include Carbon Nano-Tube (CNT) composite materials development and object avoidance technologies; that the lack of successful development of these technologies need not preclude continued development of space elevator systems in general; and that the critical technologies required for the earth-based space elevator are not required for similar systems at the Moon, and other locations. BACKGROUND In the 1990’s, advances were made by NASA Study: several researchers indicating that carbon To investigate this possibility the author, in nano-tubes might be the high strength 1999, managed for NASA a space elevator material needed for fabrication of space workshop at the NASA Marshall Space elevators from geostationary orbit down to Flight Center in Huntsville, Alabama, to the surface of the Earth.
