The launch problem for small payloads is nowhere as serious as it is for scientific and academic users, who cannot tap the purchasing power available to spacecraft funded by the military and large corporations. The options available for the researcher at a university who has an instrument or a spacecraft are limited, sometimes depressingly so. Dedicated vehicles are usually unaffordable, and secondary payload opportunities require meeting a host of requirements, from payload design to timing to integration, dependent on the needs of the primary payload. In this paper, the authors survey the options available and answer the question, “Where do I start?” Sources of potential rides, including NASA, military, commercial, and non-U.S. programs and organizations were surveyed. The results are presented here, along with recommendations for an improved process which, at low cost, could improve the “matchmaking” system and simplify the obstacle course faced by spacecraft and instrument developers today. Introduction Who To Call First While the technology to reduce the size and The payload developer can start by approaching increase the capability of small scientific and two government programs which aim to help in academic satellites continues to advance, the providing rides to space.

  • Prospects for Affordable Access to Space for Small Payloads, 2003-2012
    SSC03-III-6 Prospects for Affordable Access to Space for Small Payloads, 2003-2012 Jeff Foust Futron Corporation 7315 Wisconsin Ave., Suite 900W Bethesda, MD 20814-3202, USA +1 301-347-3405 [email protected] Abstract. Affordable access to space has been one of the key issues in the history of space exploration. It is a particularly critical issue for small payloads, where the cost of launch can run many times more than the cost of the payload itself, making many projects financially infeasible. This paper surveys the vehicles in service today as well as those announced or under development in the next decade that can address the small payload market. This analysis includes the estimated launch costs, launch rates, and capacities of the vehicles, as well as the likelihood that vehicles under development will actually enter service. Three capacity models show that the number of launch opportunities on small launch vehicles range from 212 to 471 over the next decade, depending on the availability of a number of vehicles currently under development. The introduction of partially-reusable launch vehicle systems like RASCAL and Xerus offer the best prospects for providing low-cost launch services for small satellites. Introduction find sufficient payloads with whom to share Arguably the greatest challenge for small the launch.1 satellite projects has been obtaining launch services at affordable prices. While At the same time the launch market itself spacecraft can be built relatively has been in considerable turmoil.

  • Rocket Launchers for Small Satellites Ajey Lele and Tushar Shrivastav
    IDSA Issue Brief Rocket Launchers for Small Satellites Ajey Lele and Tushar Shrivastav February 4, 2016 Summary There are multiple ways of launching small satellites into the space. In recent times, there has been a growing focus on developing exclusive vehicles for the launch of a new generation of various categories of small satellites. This issue brief discusses various such efforts to develop small satellite launch vehicles, their importance and the future. ROCKET LAUNCHERS FOR SMALL SATELLITES Introduction The history of small satellites is as old as the history of satellites. In fact, the space age could be said to have begun with the launch of a small satellite, Sputnik-1, in 1957. Until almost the first decade of the 21st century, over 860 micro-satellites, 680 nano-satellites, and 38 pico-satellites were said to have been launched worldwide.1 Though there is no precise statistics available about the exact number of small satellites launched till date, the global interest in small satellites has been growing over the years owing to various factors. During the initial years of the development of space technologies, the focus was both on developing the satellites and the vehicles capable of launching them. Over a period of time, developments in technology allowed states to position satellites into different orbits. Developments in sensor technology further enhanced the utility of satellite applicability, from ‘a space based observational platform’ to a system as ‘a decision making tool’. Integration of such multipurpose platforms helps governments to take critical decision in various areas, ranging from agricultural planning to disaster management to military operations.

  • SIPRI Yearbook 2010: Armaments, Disarmament and International Security 334 MILITARY SPENDING and ARMAMENTS, 2009
    8. World nuclear forces SHANNON N. KILE, VITALY FEDCHENKO, BHARATH GOPALASWAMY AND HANS M. KRISTENSEN I. Introduction At the start of 2010 eight nuclear weapon states possessed more than 7500 operational nuclear weapons (see table 8.1). Almost 2000 of these are kept in a state of high operational alert. If all nuclear warheads are counted— operational warheads, spares, those in both active and inactive storage, and intact warheads scheduled for dismantlement—the United States, the Rus- sian Federation, the United Kingdom, France, China, India, Pakistan and Israel together possess a total of more than 22 000 warheads. All five legally recognized nuclear weapon states, as defined by the 1968 Treaty on the Non-Proliferation of Nuclear Weapons (Non-Proliferation Treaty, NPT)—China, France, Russia, the UK and the USA—appear deter- mined to remain nuclear powers and are either modernizing or about to modernize their nuclear forces.1 At the same time, Russia and the USA are in the process of reducing their operational nuclear forces from cold war levels as a result of two bilateral treaties—the 1991 Treaty on the Reduction and Limitation of Strategic Offensive Arms (START Treaty) and the 2002 Treaty on Strategic Offensive Reductions (SORT).2 Sections II and III of this chapter discuss the composition of the deployed nuclear forces of the USA and Russia, respectively. The nuclear arsenals of the other three nuclear weapon states are considerably smaller, but all three states are either deploying new weapons or have announced their intention to do so. Sections IV–VI present data on the delivery vehicles and warhead stock- piles of the UK, France and China, respectively.

This report contains information on worldwide commercial, civil, and military orbital and commercial suborbital space launch events. Projected launches have been identified from open sources, including industry references, company manifests, periodicals, and government sources. Projected launches are subject to change. This report highlights commercial launch activities, classifying commercial launches as one or both of the following: • Internationally-competed launch events (i.e., launch opportunities considered available in principle to competitors in the international launch services market) • Any launches licensed by the Associate Administrator for Commercial Space Transportation of the Federal Aviation Administration under 49 United States Code Subtitle IX, Chapter 701 (formerly the Commercial Space Launch Act) Special Note Previous Quarterly Launch Reports have focused solely on orbital launches. However, due to increased suborbital space activity in the United States, and the possibility that it may occur in other countries in the future, this and subsequent Quarterly Launch Reports will now record FAA-licensed and equivalent international suborbital launches in addition to orbital space activity.

  • Disruptive Technology 2
    Disruptive Technology 2 In their 1995 article, ``Disruptive Technologies: Catching the Wave,'' Harvard Business School professors Joseph Bower and Clayton Christensen define two categories ofnew technology: sustaining and disruptive. Sustaining technology relies on incremental improvements to an already established technology. A good example is the conventional petrol engine used in automobiles; the principle on which it works has not changed in over a hundred years, but a modern car engine is much more reliable and efficient than that ofa 1908 model-T Ford. Disruptive technology, on the other hand, is a revolutionary technology that suddenly, and often unexpectedly, displaces an established technology. Take, for instance, the rapid market takeover by digital cameras at the expense oflong-proven and firmly established film-photography technology. According to Bower and Chris- tensen, disruptive technology initially often lacks refinement, appeals to a limited number ofpeople, and may not yet have a proven practical application (the idea is further developed in Christensen's 1997 best-selling book, The Innovator's Dilemma). Tether technology has the potential to be a disruptive technology; ifit works as advertised, it could radically change spaceflight and make conventional rocket propulsion systems largely obsolete. Ifso, it would not be the first time in history that an experimental technology totally replaced older, much better established means oftransportation. New Machines After thousands of years of development, by the 19th century sailing ships had reached an incredible level ofsophistication. They were fast, their rigging could cope with a variety ofwind conditions, and their crews were trained to run the ships as best as possible.

Introduction The study „Affordable Space Missions“ (ASM) started with the kick-off meeting on October 13/2004 and was finished with the final presentation on August 16/2005. Its goal is the investigation of the cost reduction problem for micro-satellite missions. The starting point was the question “How can we reduce micro-satellite costs by one order of magnitude at constant performance”. Foundations for that investigation are the experiences with the successful micro-satellite project BIRD [1] of the German Aerospace Center (DLR), the literature ([2]-[5], the conferences ESA 4S Symposium: Small Satellites, Systems and Services (La Rochelle, 2004) and 5th IAA Symposium on Small Satellites for Earth Observation (Berlin, 2005), and a visit at AMSAT in Marburg/Germany (2005).
