Small Launch Vehicles – a 2015 State of the Industry Survey SSC15-II-7 Small Launch Vehicles – A 2015 State of the Industry Survey Carlos Niederstrasser, Warren Frick Orbital ATK, Inc. 45101 Warp Drive, Dulles, VA 20166 USA; 703-406-5000 [email protected] ABSTRACT The first half of the 2010’s has seen a dramatic increase in potential small launch vehicle contenders, defined as rockets capable of carrying at most 1000 kg to Low Earth Orbit. Spurred on by government programs such as FALCON, SALVO, RASCAL, SWORDS, NEXT, and VCLS and the rapid proliferation of CubeSats and nanosatellites, more than 15 different commercial, semi-commercial, and government entities worldwide are now working on new entrants of this class. This paper presents an overview of all of the small satellite launch systems under development today We will compare capabilities, stated mission goals, and cost and funding sources where available. We purposely avoid making any judgements on vehicle maturity as we do not have personal insight into the design and development of many of these new entrants. The nature of this survey limited us to publically available information – whether on the web, social media, traditional media, or published papers. The authors welcome any comments, feedback, or corrections. BACKGROUND opportunities available to them.

  • 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.

  • 6. the INTELSAT 17 Satellite
    TWO COMMUNICATIONS SATELLITES READY FOR LAUNCH Arianespace will orbit two communications satellite on its fifth launch of the year: INTELSAT 17 for the international satellite operator Intelsat, and HYLAS 1 for the European operator Avanti Communications. The choice of Arianespace by leading space communications operators and manufacturers is clear international recognition of the company’s excellence in launch services. Based on its proven reliability and availability, Arianespace continues to confirm its position as the world’s benchmark launch system. Ariane 5 is the only commercial satellite launcher now on the market capable of simultaneously launching two payloads. Arianespace and Intelsat have built up a long-standing relationship based on mutual trust. Since 1983, Arianespace has launched 48 satellites for Intelsat. Positioned at 66 degrees East, INTELSAT 17 will deliver a wide range of communication services for Europe, the Middle East, Russia and Asia. Built by Space Systems/Loral of the United States, this powerful satellite will weigh 5,540 kg at launch. It will also enable Intelsat to expand its successful Asian video distrubution neighborhood. INTELSAT 17 will replace INTELSAT 702. HYLAS 1 is Avanti Communications’ first satellite. A new European satellite operator, Avanti Communications also chose Arianespace to orbit its HYLAS 2 satellite, scheduled for launch in the first half of 2012. HYLAS 1 was built by an industrial consortium formed by EADS Astrium and the Indian Space Research Organisation (ISRO), using a I-2K platform. Fitted with Ka-band and Ku-band transponders, the satellite will be positioned at 33.5 degrees West, and will be the first European satellite to offer high-speed broadband services across all of Europe.

During the decade from 1989–1998, NASA used two types of launch systems, one consisting of several families of expendable launch vehicles (ELV) and the second consisting of the world’s only partially reusable launch system—the Space Shuttle. A significant challenge NASA faced during the decade was the development of technologies needed to design and implement a new reusable launch system that would prove less expensive than the Shuttle. Although some attempts seemed promising, none succeeded. This chapter addresses most subjects relating to access to space and space transportation. It discusses and describes ELVs, the Space Shuttle in its launch vehicle function, and NASA’s attempts to develop new launch systems. Tables relating to each launch vehicle’s characteristics are included. The other functions of the Space Shuttle—as a scientific laboratory, staging area for repair missions, and a prime element of the Space Station program—are discussed in the next chapter, Human Spaceflight. This chapter also provides a brief review of launch systems in the past decade, an overview of policy relating to launch systems, a summary of the management of NASA’s launch systems programs, and tables of funding data. The Last Decade Reviewed (1979–1988) From 1979 through 1988, NASA used families of ELVs that had seen service during the previous decade.
