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.

  • Titan II Small Multisatellite Mission Approach
    I I Titan II Small Multisatellite Mission Approach Aubrey J. Butts I David F. Giere Bruce M. French Martin Marietta Astronautics Group John J. Kusnierek I Space Systems Division, USAF At the present time, small satellite programs are faced with the dilemma that they are I sometimes so small that they cannot afford the expense of a dedicated Expendable Launch Vehicle (EL V) and. therefore, must attempt to find a way to get into orbit as a secondary payload. This paper discusses another alternative, the use of a Titan II as a dedicated launch vehicle for a group of small satellites. Launches could be scheduled on a periodic I basis as a function of predicted need. The Titan II has the capability of inserting total payload weight of 3,000 to 4,000 lbs. into high-inclination, low-earth orbits and smaller payloads to higher orbits. Orbit changes are possible depending on the altitudes and I payloads weights involved. Payload fairings are available for small and large payloads. Since the total payload could conceivably consist of satellites from several unrelated programs, some type of mission "broker" or central contracting agency would be needed to develop and implement a multisatellite mission. This paper offers an approach to I implementing a mission of this type that would allow small satellites to schedule a launch on the T -II multisatellite carrier at a predetermined launch date during each year. The costs would be shared between payloads on the basis of weight and volume. This gives those small satellite programs a launch option that would provide on-orbit operation at a I predetermined time.

  • Universal Small Payload Interface – an Assessment of US Piggyback Launch Capability
    SSC00-XI-3 Universal Small Payload Interface – An Assessment of US Piggyback Launch Capability Shahed Aziz AeroAstro, Inc. 327 A Street, 5th Floor Boston, MA 02210 (617) 451-8630 [email protected] Paul Gloyer AeroAstro, Inc. Bldg 8201, Room 209 Stennis Space Center, MS 39529 (228) 688-2790 [email protected] Joel Pedlikin AeroAstro, Inc. 327 A Street, 5th Floor Boston, MA 02210 (617) 451-8630 [email protected] Kimberly Kohlhepp AeroAstro, Inc. 327 A Street, 5th Floor Boston, MA 02210 (617) 451-8630 [email protected] Abstract. Small satellites are becoming the solution of choice for planners trying to reduce space mission costs and shorten schedules. Secondary launches are a quick, frequent, low-cost, reliable solution for small satellites. Most international small spacecraft are launched as secondary piggyback payloads, aboard larger more efficient rockets. However, piggyback accommodations in the US are rare, done only on a case-by-case basis, and far from low cost. AeroAstro is presently developing the Universal Small Payload Interface (USPI), a standardized template for integrating and launching small spacecraft. It is designed so that mission developers can design to its requirements in order to be compatible on demand with a number of different secondary launch vehicle slots. The ‘Phase A’ USPI, based exclusively on existing secondary opportunities, will be complete by August 2000. Phases B and C, based on potential modifications of existing launch vehicles, will be complete by the end of the year. Missions will be quickly designed to a common interface standard, decreasing their dependence on a specific launch. When the spacecraft is ready, the next USPI launch available will be used, bringing ‘launch on-demand’ closer to reality.
