The Steep Climb to Low Earth Orbit: A History of the Space Elevator Community's Battle Against the Rocket Paradigm

Pearson, Derek J. 13 June 2022 (has links)
This thesis examines the growth of the space elevator community in America from 1975 to 2010. It argues that the continued practical failures of the space elevator, a proposed technology for efficiently transporting payloads and people into space without conventional propulsion sources, resulted from a technological paradigm built around the rocket and supported by a traditional engineering culture. After its triumph in landing men on the Moon from 1969 to 1972, the United States' National Aeronautics and Space Administration (NASA) sought to advance novel concepts for further space exploration, but it fumbled in pursuing nontraditional notions of escaping the atmosphere such as the space elevator. Employing interviews with space elevator advocates Bradley Edwards and Michael Laine and other primary and secondary sources, this thesis also draws on concepts such as technological paradigms, engineering cultures, and the technological sublime. It concludes by demonstrating how success eluded the marginalized space elevator researchers who found themselves grappling with the vast social and technical system that supported the rocket's hegemony. / Master of Arts / This thesis examines the growth of the space elevator community in America from 1975 to 2010. It argues that the continued practical failures of the space elevator, a proposed technology for efficiently transporting payloads and people into space without conventional propulsion sources, resulted from a technological paradigm built around the rocket and supported by a traditional engineering culture. The technological paradigm of the rocket encompassed all of the people and practices that made the rocket work. After its triumph in landing men on the Moon from 1969 to 1972, the United States' National Aeronautics and Space Administration (NASA) sought to advance novel concepts for further space exploration, but it fumbled in pursuing nontraditional notions of escaping the atmosphere such as the space elevator. Much of this failure is owed to an engineering culture within NASA that looked down upon challenging the rocket. This thesis demonstrates how success eluded the marginalized space elevator researchers who found themselves grappling with the vast social and technical system that supported the rocket's hegemony.

Transportation Study of Release from a Space Elevator to Cislunar Space / Transportstudie av frigöring från en rymdhiss till Cislunar-rymden

Griffin, Daniel January 2023 (has links)
To leave Earth’s gravity well and ascend into Cislunar space takes ingenuity, and the engineering feats of many. Now to propel humanity further into space, rockets will need assistance to provide the large requirements of mass to be used for space structures. Tsiolkovsky’s Rocket Equation greatly limits the advantages of rockets and leaves an opening for Space Elevators to assist in a dual space access approach. By moving a large amount of mass routinely, efficiently, environmentally friendly and with daily launches towards space. Along with the apex anchor situated at 100,000 km for emergency assistance across all Cislunar space, and to act as both storage facilities and a construction zone. Space Elevators are the railway to space and can supplement rockets by transforming how mass is transported to Cislunar space and beyond. / Att lämna jordens gravitationsbrunn och stiga upp i Cislunar-rymden kräver uppfinningsrikedom och mångas ingenjörsprestationer. För att nu driva mänskligheten längre ut i rymden kommer raketer att behöva hjälp för att tillhandahålla de stora kraven på massa som ska användas för rymdstrukturer. Tsiolkovskys raketekvation begränsar i hög grad fördelarna med raketer och lämnar en öppning för rymdhissar för att hjälpa till med en dubbel rymdtillgång. Rymdhissar kan att flytta en stor mängd massa rutinmässigt, effektivt, miljövänligt och med dagliga uppskjutningar mot rymden. Apex-ankaret som ligger på 100 000 km kan fungera för nödhjälp över hela Cislunar-utrymmet och som både lagringsutrymmen och en konstruktionszon. Rymdhissar är järnvägen till rymden och kan komplettera raketer genom transformation hur massa transporteras till Cislunar rymden och bortom.
