Launch and Deployment Analysis for a Small, MEO, Technology Demonstration Satellite
46th AIAA Aerospace Sciences Meeting and Exhibit AIAA 2008-1131 7 – 10 January 20006, Reno, Nevada Launch and Deployment Analysis for a Small, MEO, Technology Demonstration Satellite Stephen A. Whitmore* and Tyson K. Smith† Utah State University, Logan, UT, 84322-4130 A trade study investigating the economics, mass budget, and concept of operations for delivery of a small technology-demonstration satellite to a medium-altitude earth orbit is presented. The mission requires payload deployment at a 19,000 km orbit altitude and an inclination of 55o. Because the payload is a technology demonstrator and not part of an operational mission, launch and deployment costs are a paramount consideration. The payload includes classified technologies; consequently a USA licensed launch system is mandated. A preliminary trade analysis is performed where all available options for FAA-licensed US launch systems are considered. The preliminary trade study selects the Orbital Sciences Minotaur V launch vehicle, derived from the decommissioned Peacekeeper missile system, as the most favorable option for payload delivery. To meet mission objectives the Minotaur V configuration is modified, replacing the baseline 5th stage ATK-37FM motor with the significantly smaller ATK Star 27. The proposed design change enables payload delivery to the required orbit without using a 6th stage kick motor. End-to-end mass budgets are calculated, and a concept of operations is presented. Monte-Carlo simulations are used to characterize the expected accuracy of the final orbit. -

However, since the late 1990s the global commercial launch market has generally declined following the downturn in the telecommunications services industry, which was the primary customer of the commercial space industry. Given this trend, U.S. launch services providers struggling to remain economically viable have been bolstered by the Commercial Space Act of 1998 (Public Law 105-303), which requires NASA and other Federal agencies to plan missions and procure space transportation services from U.S. -

Aas 14-281 Suborbital Intercept And
AAS 14-281 SUBORBITAL INTERCEPT AND FRAGMENTATION OF ASTEROIDS WITH VERY SHORT WARNING TIMES Ryan Hupp,∗ Spencer Dewald,∗ and Bong Wiey The threat of an asteroid impact with very short warning times (e.g., 1 to 24 hrs) is a very probable, real danger to civilization, yet no viable countermeasures cur- rently exist. The utilization of an upgraded ICBM to deliver a hypervelocity as- teroid intercept vehicle (HAIV) carrying a nuclear explosive device (NED) on a suborbital interception trajectory is studied in this paper. Specifically, this paper focuses on determining the trajectory for maximizing the altitude of intercept. A hypothetical asteroid impact scenario is used as an example for determining sim- plified trajectory models. Other issues are also examined, including launch vehicle options, launch site placement, late intercept, and some undesirable side effects. It is shown that silo-based ICBMs with modest burnout velocities can be utilized for a suborbital asteroid intercept mission with an NED explosion at reasonably higher altitudes (> 2,500 km). However, further studies will be required in the following key areas: i) NED sizing for properly fragmenting small (50 to 150 m) asteroids, ii) the side effects caused by an NED explosion at an altitude of 2,500 km or higher, iii) the rapid launch readiness of existing or upgraded ICBMs for a suborbital asteroid intercept with short warning times (e.g., 1 to 24 hrs), and iv) precision ascent guidance and terminal intercept guidance. It is emphasized that if an earlier alert (e.g., > 1 week) can be assured, then an interplanetary inter- cept/fragmentation may become feasible, which requires an interplanetary launch vehicle. -
Searching for Intelligent Life in Alien Skies Harry Thomas December 2020 Dr. Sarah Johnson
Atmospheric Technosignatures: Searching for Intelligent Life in Alien Skies Harry Thomas December 2020 Dr. Sarah Johnson (STIA 227: Environmental Geoscience) Introduction In 1950, the famed physicist Enrico Fermi was out to lunch with colleagues when he asked, “Do you ever wonder where everybody is?” The Fermi Paradox has come to describe the disparity between the abundance of star systems, with a multitude of planets that might harbor 1 life, and the lack of detectable alien civilizations. This question, rooted in a deeper existential curiosity about our place in the cosmos, has fueled researchers to search for signs of alien intelligence. So far, none have been detected. Since 1992, over 4000 planets have been found orbiting stars outside of the solar system. Some of these planets, known as exoplanets, are similar to Earth in terms of their composition 2 and the amount of radiation they receive from their host star. The search for extraterrestrial intelligence has largely revolved around the search for alien radio transmissions, but there is a growing contingent of scientists who argue that we should be searching for other indicators of alien civilizations. Some of the most promising of these indicators, better known as technosignatures, can be found in the skies and orbits of exoplanets. Technosignatures Technosignature is a broad term that can be applied to anything that indicates the presence of a technologically developed civilization. Its list of engendering technologies runs the gamut from ones that are well within the grasp of human technological reality to ones that stretch the limits of imagination; both the burning of chemical fuels and Dyson Spheres, massive arrays of solar collectors that enclose an entire star to capture as much of its energy as possible, are fair 3 game for technosignatures. -
Producers of Popular Science Web Videos – Between New Professionalism and Old Gender Issues
Producers of Popular Science Web Videos – Between New Professionalism and Old Gender Issues Jesús Muñoz Morcillo1*, Klemens Czurda*, Andrea Geipel**, Caroline Y. Robertson-von Trotha* ABSTRACT: This article provides an overview of the web video production context related to science communication, based on a quantitative analysis of 190 YouTube videos. The authors explore the main characteristics and ongoing strategies of producers, focusing on three topics: professionalism, producer’s gender and age profile, and community building. In the discussion, the authors compare the quantitative results with recently published qualitative research on producers of popular science web videos. This complementary approach gives further evidence on the main characteristics of most popular science communicators on YouTube, it shows a new type of professionalism that surpasses the hitherto existing distinction between User Generated Content (UGC) and Professional Generated Content (PGC), raises gender issues, and questions the participatory culture of science communicators on YouTube. Keywords: Producers of Popular Science Web Videos, Commodification of Science, Gender in Science Communication, Community Building, Professionalism on YouTube Introduction Not very long ago YouTube was introduced as a platform for sharing videos without commodity logic. However, shortly after Google acquired YouTube in 2006, the free exchange of videos gradually shifted to an attention economy ruled by manifold and omnipresent advertising (cf. Jenkins, 2009: 120). YouTube has meanwhile become part of our everyday experience, of our “being in the world” (Merleau Ponty) with all our senses, as an active and constitutive dimension of our understanding of life, knowledge, and communication. However, because of the increasing exploitation of private data, some critical voices have arisen arguing against the production and distribution of free content and warning of the negative consequences for content quality and privacy (e.g., Keen, 2007; Welzer, 2016). -
