Shifting Understandings of Imperialism: A Collision of Cultures in Starship Troopers and Ender's Game

Perniciaro, Leon 20 May 2011 (has links)
In this paper, I consider how Robert Heinlein's Starship Troopers (1959) and Orson Scott Card's Ender's Game (1985) allegorically treat U.S. Cold War fears of invasion by the Soviet Union. Given the texts' historical relationship to the Vietnam War and their use of very similar science fiction tropes (namely, invasion by communistic, insect-like aliens), I argue that Orson Scott Card reimagines the binary Cold War conflict, softening the rhetoric of Starship Troopers and allowing for a more qualified understanding of the relationship between the U.S.S.R. and the U.S. Through this analysis, I also consider how science fiction is a useful tool of cultural criticism in that it posits future worlds so as to reflect contemporary social concerns.

Molten Regolith Electrolysis Processing for Lunar ISRU: Financial and Physics Analysis of SpaceX Starship Transportation

Harper, Cheyenne 01 January 2021 (has links)
The purpose of the following research is to explore molten regolith electrolysis (MRE) methodology for in-situ resource utilization (ISRU) of Highlands lunar regolith, to be explored during the initial Artemis missions. An analysis of potential commercial launch providers for MRE-equipment based on technology-readiness level (TRL), payload mass support, and $ USD/kg payload price is provided. SpaceX is ultimately proposed as a launch provider of MRE equipment following multi-factorial analysis, with the SpaceX Starship human landing system (HLS) variant proposed for supporting MRE payload. Finally, customers of regolith-derived oxygen, aluminum, and silicon are distinguished to form the business case for operating MRE equipment on the lunar surface.

Fundamental Undemocratic Values in Robert A. Heinlein’s Starship Troopers: How to Make Upper Secondary School Students More Self-aware of Their Fundamental Democratic Values

Forsman, Sebastian January 2019 (has links)
Democracy and democratic values have stagnated and are under attack. Current criticism of democracy points towards problems with efficiency, leniency towards undemocratic elements, collective problem-solving, and a suspension of the rule of law for public good. One solution to these problems could be to focus on teaching democratic values through literature in school. A suitable novel for this endeavor is the science-fiction novel Starship Troopers, written by Robert A. Heinlein in 1959, since it functions as fictional criticism and an alternative to democracy. However, most of the previous research conducted on Starship Troopers have focused on aspects regarding militarism and fascism. This research paper differs because it focuses specifically on how democracy is critiqued in the novel and how this critique could be used to teach democratic values. Teaching democratic values should be conducted since democracy and democratic values are arguably the most essential aspects of the fundamental values of the Swedish school system. Still, the relevant school policy documents do not define how these fundamental values are connected to the system of democracy and how they could be taught in a classroom. In order to fill that gap, this paper aims to use the theories and methods of didactic potential, Socratic pedagogy, and the politics of advocacy, attack, and assent to help students become more self-aware of their fundamental democratic values. The analysis demonstrates that Starship Troopers criticizes essential elements of democracy and complements those elements with its own alternative fundamental elements and values. The analysis also demonstrates how this critique can be used as a complement in a philosophical discussion that helps students become more self-aware of their fundamental democratic values.

Multiple Asteroid Retrieval Mission

Gargioni, Gustavo 11 May 2020 (has links)
In this thesis, the possibility of enabling space-mining for the upcoming decade is explored. Making use of recently-proven reusable rockets, we envision a fleet of spacecraft capable of reaching Near-Earth asteroids. To analyze this idea, the goal of this problem is to maximize the asteroid mass retrieved within a spacecraft max life span. Explicitly, the maximum lifetime of the spacecraft fleet is set at 30 years. A fuel supply-chain is proposed and designed so that each spacecraft is refueled before departing for each asteroid. To maximize access to the number of asteroids and retrievable mass for each mission, we propose launching each mission from an orbit with low escape velocity. The L2-Halo orbit at the libration point in the Earth-Moon system was selected due to its easy access from Low-Earth Orbit and for a cislunar synergy with NASA Gateway. Using data from NASA SmallBody and CNEOS databases, we investigated NEAs in the period between 2030 and 2060 could be captured in the ecliptic plane and returned to L2-Halo with two approaches, MARM-1 and MARM-2. Together, these databases provide all information for every asteroid's close approach known today. Returning the asteroid as a whole is explored in the MARM-1 method, while MARM-2 evaluates the possibility of reaching larger asteroids and returning a fragment of their masses, such that it optimizes the available cargo weight per time of flight of each mission. The following results are compared with previous work from the community. The results show a 96% reduction in the cost per kg, with an enormous increase in retrieved mass. With these results, this thesis shows that not solely energy or dynamic optimization will be responsible for proving space mining feasibility, but rather a combination of those and business best practices. Proving feasibility for space mining is a complex and immense problem. Although this thesis opens new possibilities for future work on the field and sparkes the interest of private endeavors, the final solution for this problem still requires additional exploration. / M.S. / In this thesis, the possibility of enabling space-mining for the upcoming decade is explored.

Paul Verhoeven, media manipulation, and hyper-reality

Malchiodi, Emmanuel William 01 May 2011 (has links)
Does the individual really matter in the post-modern world, brimming with countless signs and signifiers? My main objective in this writing is to demonstrate how this happens in Verhoeven's films, exploring his central themes and subtext and doing what science fiction does: hold a mirror up to the contemporary world and critique it, asking whether our species' current trajectory is beneficial or hazardous.; Dutch director Paul Verhoeven is a polarizing figure. Although many of his American made films have received considerable praise and financial success, he has been lambasted on countless occasions for his gratuitous use of sex, violence, and contentious symbolism--1995s Showgirls was overwhelmingly dubbed the worst film of all time and 1997s Starship Troopers earned him a reputation as a fascist. Regardless of the controversy surrounding him, his science fiction films are a move beyond the conventions of the big blockbuster science fiction films of the 1980s (E.T. and the Star Wars trilogy are prime examples), revealing a deeper exploration of both sociopolitical issues and the human condition. Much like the novels of Philip K. Dick (and Verhoeven's 1990 film Total Recall--an adaptation of a Dick short story), Verhoeven's science fiction work explores worlds where paranoia is a constant and determining whether an individual maintains any liberty is regularly questionable. In this thesis I am basically exploring issues regarding power. Although I barely bring up the term power in it, I feel it is central. Power is an ambiguous term; are we discussing physical power, state power, objective power, subjective power, or any of the other possible manifestations of the word? The original Anglo-French version of power means "to be able," asking whether it is possible for one to do something. In relation to Verhoeven's science fiction work each demonstrates the limitations placed upon an individual's autonomy, asking are the protagonists capable of independent agency or rather just environmental constructs reflecting the myriad influences surrounding them.
