Space Launch System (Sls) Motors
Propulsion Products Catalog SPACE LAUNCH SYSTEM (SLS) MOTORS For NASA’s Space Launch System (SLS), Northrop Grumman manufactures the five-segment SLS heavy- lift boosters, the booster separation motors (BSM), and the Launch Abort System’s (LAS) launch abort motor and attitude control motor. The SLS five-segment booster is the largest solid rocket motor ever built for flight. The SLS booster shares some design heritage with flight-proven four-segment space shuttle reusable solid rocket motors (RSRM), but generates 20 percent greater average thrust and 24 percent greater total impulse. While space shuttle RSRM production has ended, sustained booster production for SLS helps provide cost savings and access to reliable material sources. Designed to push the spent RSRMs safely away from the space shuttle, Northrop Grumman BSMs were rigorously qualified for human space flight and successfully used on the last fifteen space shuttle missions. These same motors are a critical part of NASA’s SLS. Four BSMs are installed in the forward frustum of each five-segment booster and four are installed in the aft skirt, for a total of 16 BSMs per launch. The launch abort motor is an integral part of NASA’s LAS. The LAS is designed to safely pull the Orion crew module away from the SLS launch vehicle in the event of an emergency on the launch pad or during ascent. Northrop Grumman is on contract to Lockheed Martin to build the abort motor and attitude control motor—Lockheed is the prime contractor for building the Orion Multi-Purpose Crew Vehicle designed for use on NASA’s SLS.

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.

Control of NASA's Space Launch System
Success Stories FOR CONTROL Control of NASA’s Space Launch System The flight control system for the NASA Space Launch System (SLS) employs a control architecture that evolved from Saturn, Space Shuttle, and Ares I-X while also incorporating modern enhancements. This control system, baselined for the first unmanned launch, has been verified and successfully flight-tested on the Ares I-X rocket and an F/A-18 aircraft. The development of the launch vehicle itself came on the heels of the Space Shuttle retirement in 2011 and will deliver more payload to orbit and produce more thrust than any other vehicle, past or present, opening the way to new frontiers of space exploration as it carries the Orion crew vehicle, equipment, and experiments into new territories. The initial 70-metric-ton vehicle consists of four RS-25 core stage engines from the Space Shuttle inventory, two five-segment solid rocket boosters that are advanced versions of the Space Shuttle boosters, and a core stage that resembles the External Tank and carries the liquid propellant while also serving as the vehicle’s structural backbone. Just above SLS’s core stage is the Interim Cryogenic Propulsion Stage (ICPS), based on the payload motor used by the Delta IV Evolved Expendable Launch Vehicle (EELV). Challenges of Controlling the Space Launch System As with all large launch vehicles, the SLS control system must balance the competing needs of maximizing performance while maintaining robustness to limitations in preflight models. With its high thrust, large size, and multistructural load paths, SLS exhibits a high degree of structural flexion with nonplanar characteristics.

Launch Vehicle Control Center Architectures
Launch Vehicle Control Center Architectures Michael D. Watson1, Amy Epps2, and Van Woodruff3 NASA Marshall Space Flight Center, Huntsville, AL 35812 Michael Jacob Vachon4 NASA Johnson Space Center, Houston, TX 77058 Julio Monreal5 European Space Agency, Launchers Directorate, Paris, France Marl Levesque6 United Launch Alliance, Vandenberg AFB and Randall Williams7 and Tom McLaughlin8 Aerospace Corporation, El Segundo, CA 90245 Launch vehicles within the international community vary greatly in their configuration and processing. Each launch site has a unique processing flow based on the specific launch vehicle configuration. Launch and flight operations are managed through a set of control centers associated with each launch site. Each launch site has a control center for launch operations; however flight operations support varies from being co-located with the launch site to being shared with the space vehicle control center. There is also a nuance of some having an engineering support center which may be co-located with either the launch or flight control center, or in a separate geographical location altogether. A survey of control center architectures is presented for various launch vehicles including the NASA Space Launch System (SLS), United Launch Alliance (ULA) Atlas V and Delta IV, and the European Space Agency (ESA) Ariane 5. Each of these control center architectures shares some similarities in basic structure while differences in functional distribution also exist. The driving functions which lead to these factors are considered and a model of control center architectures is proposed which supports these commonalities and variations. I. INTRODUCTION Launch vehicles in both Europe and the United States have been operating successfully for several decades.

SPACE LAUNCH SYSTEM PAYLOAD TRANSPORTATION BEYOND LEO. S. D. Creech1, J. D. Baker2, A. L. Jackman3 and G. Vane4, 1NASA/MSFC
Planetary Science Vision 2050 Workshop 2017 (LPI Contrib. No. 1989) 8060.pdf SPACE LAUNCH SYSTEM PAYLOAD TRANSPORTATION BEYOND LEO. S. D. Creech1, J. D. Baker2, A. L. Jackman3 and G. Vane4, 1NASA/MSFC Huntsville, AL 35812, [email protected], 2Jet Propulsion Laboratory, Pasadena, CA 91109, [email protected], 3NASA/MSFC Huntsville, AL 35812, [email protected], and 4Jet Propulsion Laboratory, Pasadena, CA 91109, [email protected] Introduction: NASA has successfully completed the Critical Design Review (CDR) of the heavy lift Space Launch System (SLS) and is working towards the first flight of the vehicle in 2018. SLS will begin flying crewed missions with an Orion capsule to the lunar vicinity every year after the first 2 flights starting in the early 2020's. As early as 2021, in addition to delivering an Orion capsule to a cislunar destination, SLS will also deliver ancillary payload, termed “Co- manifested Payload (CPL)”, with a mass of at least 5.5 mT and volume up to 280 m3 simultaneously to that same destination. Later SLS flights have a goal of delivering as much as 10 mT of CPL to cislunar destinations. In addition to cislunar destinations, SLS flights may deliver non-crewed, science-driven missions with Primary Payload (PPL) to more distant destinations. SLS PPL missions will utilize a unique payload fairing offering payload volume (ranging from 320 m3 to 540 m3) that greatly exceeds the largest existing Expendable Launch Vehicle (ELV) fairing available. The Characteristic Energy (C3) offered by the SLS system will generate opportunities to deliver up to 40 mT to cislunar space, and deliver double PPL mass or decrease flight time by half for some outer planet destinations when compared to existing capabilities.

Alternatives for Future U.S. Space-Launch Capabilities Pub
CONGRESS OF THE UNITED STATES CONGRESSIONAL BUDGET OFFICE A CBO STUDY OCTOBER 2006 Alternatives for Future U.S. Space-Launch Capabilities Pub. No. 2568 A CBO STUDY Alternatives for Future U.S. Space-Launch Capabilities October 2006 The Congress of the United States O Congressional Budget Office Note Unless otherwise indicated, all years referred to in this study are federal fiscal years, and all dollar amounts are expressed in 2006 dollars of budget authority. Preface Currently available launch vehicles have the capacity to lift payloads into low earth orbit that weigh up to about 25 metric tons, which is the requirement for almost all of the commercial and governmental payloads expected to be launched into orbit over the next 10 to 15 years. However, the launch vehicles needed to support the return of humans to the moon, which has been called for under the Bush Administration’s Vision for Space Exploration, may be required to lift payloads into orbit that weigh in excess of 100 metric tons and, as a result, may constitute a unique demand for launch services. What alternatives might be pursued to develop and procure the type of launch vehicles neces- sary for conducting manned lunar missions, and how much would those alternatives cost? This Congressional Budget Office (CBO) study—prepared at the request of the Ranking Member of the House Budget Committee—examines those questions. The analysis presents six alternative programs for developing launchers and estimates their costs under the assump- tion that manned lunar missions will commence in either 2018 or 2020. In keeping with CBO’s mandate to provide impartial analysis, the study makes no recommendations.
