READ MORE AT PLACESJOURNAL.ORG. The Shape of Space What the orbital space habitats designed for NASA in 1975 can teach us about living in new geometries. FRED SCHARMEN AUGUST 2018 Bernal Sphere, 1975. [Rick Guidice/Nasa Ames Research Center] “The sky starts at your feet. Think how brave you are to walk around.” 1 — Anne Herbert “Space is not only high, it’s low. It’s a bottomless pit.” 2 — Sun Ra Buckminster Fuller had an unusual way of talking about stairs. Instead of downstairs and upstairs, he encouraged people to say instairs and outstairs. “They all laugh about it,” he wrote, “But if they try saying in and out for a few days in fun, they find themselves beginning to realize that they are indeed going inward and outward in respect to the center of Earth, which is our Spaceship Earth. And for the first time they begin to feel real 3 reality.” Writing in 1970, at the dawn of extra-planetary space travel, Fuller identified a break in humans’ spatial perception. Standing on Earth, we see the ground plane as flat, but we know the planet is a sphere. To describe motion and existence in a vast universe, where planetary surfaces are the exception, we would need a new language. For centuries, the space away from the Earth’s surface — “outer” space — has confounded attempts to make sense of it with terrestrial geometric schemes. -

Potential Visitor Impact from One Rocket Launch (PDF)
TO: Spaceport Camden FROM: The Center for Business Analytics and Economic Research DATE: October 5, 2020 SUBJECT: Potential Visitor Impact from One Rocket Launch Introduction Spaceport Camden is continuing to follow the development process required to become an operating commercial spaceport. This spaceport will focus on small-lift launch vehicles that typically cover rockets with a payload of 2,000 kg (4,400 lbs.) that go into low earth orbit (LEO).1 When these launches begin at Spaceport Camden, the majority of the economic impact will be generated by the direct operations of the businesses located at the spaceport and visitors who come to watch these launches. For the purposes of this memorandum, the Center for Business Analytics and Economic Research is focusing on the visitors who will come to watch or aid with the launches. Within the visitor segment, tourists who are willing to travel to watch a launch typically fall into two different market segments. First is the Space Enthusiasts’ market, which includes 10.8 percent of the U.S. population, and the other is the Educational Families’ market, which covers 4.9 percent of the U.S. population.2 Both of these markets are different than the adventure market that is interested in traveling to space as a space tourist.3 The space tourist market is not included in the economic impact segment of this analysis because the needs of these visitors are very different from those of the other types of visitors; however, given the potential for development within this market, CBAER has included an overview of the space tourism market within this memorandum. -

Modular Inflatable Space Habitats First European Workshop on Inflatable Space Structures 21 – 22 May 2002, ESA/ESTEC, Noordwijk, The Netherlands Andreas Vogler, dipl. Arch ETH(1) (1)University of Technology Munich Arcisstrasse 21 D-80290 Munich, Germany Email:[email protected] ABSTRACT In space we find an extreem vacuum. Human beings need an atmosphere to survive. This makes inflatables most apt for use in human space flight. Savings in weight and packaging volume are perfect for getting them off ground. With the development of TransHab, NASA made a big step forward in proofing the technology-readiness of using inflatables for human space habitat. Protection of micro-meteorites and radiation proofed to be even better than in the aluminium ISS Module. The shape of TransHab was based on a toroid. The sphere is the natural shape of a flexible skin with an inside pressure and naturally combining maximum volume with minimum surface (insulation/protection etc). It is astonishing why this very efficient shape has not been used more often for space applications. This paper will investigate on a concept level the possibilities of a sphere for use in microgravity and planetary habitats. Possibilities for habitats for 1-2 person, 6 persons and up to sixty and more, all using the same basic standard modules and morphology. Even a whole self-sufficient space station with artificial gravity where the big structure resembles - like in a fractal system - the smallest unit will be proposed. INTRODUCTION Inflatable structures have always been a obvious alternative for space structures, since they combine stability with a high volume/weight ratio. -
National Spaceport Network Development Plan
SPfciCEPORT ALLIANCE National Spaceport Network Development Plan Prepared by the Global Spaceport Alliance for the Office of Spaceports Office of Commercial Space Transportation Federal Aviation Administration June 1, 2020 EXECUTIVE SUMMARY Space has become an indispensable part of everyday life in the 21st century, supporting not only our nation's military and intelligence capabilities, but also communications, navigation, weather forecasting, agriculture, financial transactions, disaster response, and even entertainment. The Eastern Range, located at Cape Canaveral Air Force Station, Florida, and the Western Range, located at Vandenberg Air Force Base, California, have served as the military's primary launch sites for space launches and missile tests for more than 60 years. Many NASA and commercial space missions have also been conducted from those locations. Recently however, a number of commercial spaceports have been established by state and local governments, or by private companies, based on a desire to take advantage of the growing space economy, to minimize the federal regulatory burden, and to provide additional launch opportunities for civil and commercial space missions. The development of a National Spaceport Network, consisting of current and prospective commercial spaceports, government-owned-and-operated launch & landing sites, and privately- owned-and-operated launch & landing sites, offers an opportunity to increase the safety, capacity, efficiency, and resiliency of the nation's space operations. Such a network could provide the framework for formal or informal public-private partnerships between federal, state, and local governments; the aerospace industry; and academia. A key component of the operation of a successful network of spaceports is federal funding for infrastructure development. -

THE RINGS of the EARTH Reyes González JM Dr. Archi
67rd International Astronautical Congress, Guadalajara, Mexico. 2016 by the International Astronautical Federation. IAC-16,D3,IP,3,x32256 Life beyond Earth: THE RINGS OF THE EARTH Reyes González JM Dr. Architect, lecturer at Alfonso X El Sabio University, Spain, [email protected] Cobo Arevalo A. PhD. candidate Architect at U.Politechnique de Madrid, Spain, [email protected] JM de Prada Poole’s (1) Orbital Megalopolis envisions 5 concentric rings of circular cross-section, in orbit at an average height of 35.750 km above the Earth's crust (like the rings around Saturn, but with different dimensions and a different objective). Each of these rings functions in the same way as a 84.330 km diameter torus, hosting a population of 2,500 million people and providing for all their needs in its interior. The main aim of the project is to empty planet Earth of most of its human population, and thus allow the biosphere to continue its natural evolution without having to bear the harmful interference and burden of humankind. This article describes the composition and size of one of these rings, and compares its parts with other similar ones already built by the human species. It begins with a brief explanation of the historical background and an introduction discussing demographic development over the last two centuries and its most immediate consequences. I. ZERO PEOPLE Air pollution, the hole in the ozone layer, degraded soil, deforestation, marine pollution, rising temperatures, drought, biodiversity loss …. 25 years after the Rio-92 2nd "Earth Summit" and its "declaration on environment and development", governments and the governed have hardly progressed at all.
