SPACE TECHNOLOGY LABORATORIES, INC. PUBLIC RELATIONS - ORCHARD 0-1311 * EXT 2001-2-3 5730 ARBOR VITAE STREET, LOS ANGELES 45 CALIFORNIA FOR IMMEDIA!lX RELEASE THOR-ABLE I11 Thor-Able I11 is the latest version of a rocket configuration that has served as the vehicle for a number of important missile and space experiments. Originally designed to test second-generation nose cones at ICBM ranges, altitudes and speeds, the first Able vehicle was launched in the Spring of 1958. Proposed and developed by Space Technology Laboratories, Inc., Los Angeles, it consisted of a Thor IRBM topped with a second stage similar to that used in the mor-Able I11 vehicle. Able traveled intercohtinental distances, the first to do so in the history of the nation's ballistic missile program. On two occasions during record breaking flights, Able carried a mouse in its nose cone. Labeled Project MIA (Mouse In Able), the bio- medical elrperiment provided information on the effects of space flight and weightlessness on a living organism. The mice carried aloft in the Able nose cones traveled further into space than any animal to date. Following success of the Able flights, scientists at STL determined that the same canbination with additional stages added would provide the country with a rocket capable of traveling great distances into space. - more - -2- The resulting space probe vehicle, Able-1, sent its payload further and faster into space than any rocket up to that time. Weighing 85 pounds, Pioneer I traveled a distance of 7O,OOO miles into space before falling back to burn in the earth's atmosphere. During the flight valuable information on the space environment was collected by its instrumentation and relayed to ground tracking stations. At present another series of advanced Able two-stage rockets continues tests over ICBM distances, carrying out experiments vital to the development of advanced missile designs and materials. From the idea of combining existing hardware to form the Able test vehicle has come a "workhorse" of the space probe program. Its latest form, Thor-Able 111, has placed the most ccmrplex packsge of instrumentation yet developed into an orbit around the earth far larger than any other, continuing the long line of Able's achievements. .

The Advanced Cryogenic Evolved Stage (ACES)- a Low-Cost, Low-Risk Approach to Space Exploration Launch
The Advanced Cryogenic Evolved Stage (ACES)- A Low-Cost, Low-Risk Approach to Space Exploration Launch J. F. LeBar1 and E. C. Cady2 Boeing Phantom Works, Huntington Beach CA 92647 Space exploration top-level objectives have been defined with the United States first returning to the moon as a precursor to missions to Mars and beyond. System architecture studies are being conducted to develop the overall approach and define requirements for the various system elements, both Earth-to-orbit and in-space. One way of minimizing cost and risk is through the use of proven systems and/or multiple-use elements. Use of a Delta IV second stage derivative as a long duration in-space transportation stage offers cost, reliability, and performance advantages over earth-storable propellants and/or all new stages. The Delta IV second stage mission currently is measured in hours, and the various vehicle and propellant systems have been designed for these durations. In order for the ACES to have sufficient life to be useful as an Earth Departure Stage (EDS), many systems must be modified for long duration missions. One of the highest risk subsystems is the propellant storage Thermal Control System (TCS). The ACES effort concentrated on a lower risk passive TCS, the RL10 engine, and the other subsystems. An active TCS incorporating a cryocoolers was also studied. In addition, a number of computational models were developed to aid in the subsystem studies. The high performance TCS developed under ACES was simulated within the Delta IV thermal model and long-duration mission stage performance assessed.

Evolved Expendable Launch Operations at Cape Canaveral, 2002-2009
EVOLVED EXPENDABLE LAUNCH OPERATIONS AT CAPE CANAVERAL 2002 – 2009 by Mark C. Cleary 45th SPACE WING History Office PREFACE This study addresses ATLAS V and DELTA IV Evolved Expendable Launch Vehicle (EELV) operations at Cape Canaveral, Florida. It features all the EELV missions launched from the Cape through the end of Calendar Year (CY) 2009. In addition, the first chapter provides an overview of the EELV effort in the 1990s, summaries of EELV contracts and requests for facilities at Cape Canaveral, deactivation and/or reconstruction of launch complexes 37 and 41 to support EELV operations, typical EELV flight profiles, and military supervision of EELV space operations. The lion’s share of this work highlights EELV launch campaigns and the outcome of each flight through the end of 2009. To avoid confusion, ATLAS V missions are presented in Chapter II, and DELTA IV missions appear in Chapter III. Furthermore, missions are placed in three categories within each chapter: 1) commercial, 2) civilian agency, and 3) military space operations. All EELV customers employ commercial launch contractors to put their respective payloads into orbit. Consequently, the type of agency sponsoring a payload (the Air Force, NASA, NOAA or a commercial satellite company) determines where its mission summary is placed. Range officials mark all launch times in Greenwich Mean Time, as indicated by a “Z” at various points in the narrative. Unfortunately, the convention creates a one-day discrepancy between the local date reported by the media and the “Z” time’s date whenever the launch occurs late at night, but before midnight. (This proved true for seven of the military ATLAS V and DELTA IV missions presented here.) In any event, competent authorities have reviewed all the material presented in this study, and it is releasable to the general public.

Two-Stage, High-Altitude Rocket with Internal Skeleton Design Entered in Advance Category of 7Th ESRA IREC
Two-Stage, High-Altitude Rocket with Internal Skeleton Design Entered in Advance Category of 7th ESRA IREC Samuel S. Bowman1, Kevin J. Byrne2, Allen Capatina3, Aliki S. Loper-Leddy4, and Joshua A. Van Schoyck5 California Polytechnic State University, San Luis Obispo, CA, 93407 A high-altitude, two-stage rocket was designed, built, and entered in the advanced category of the 7th Annual Experimental Sounding Rocket Association (ESRA) Intercollegiate Rocketry Engineering Competition (IREC). The rocket, called AJAKS, featured an internal skeleton made of carbon fiber rods, and a combination of plywood, carbon, and aluminum bulkheads. Loads were driven through the internal structure, with an outer skin tube providing an aerodynamic surface. A unique separation device was developed to ensure proper stage separation. The competition required the rocket to carry a 10-lb payload, which was chosen by the team to consist of an IMU and data logging computer for recording the descent profile, a CubeSat test unit, and a digital video recorder. Prior to the competition launch, AJAKS was test launched on May 5th in the Mojave at the Friends of Amateur Rocketry (FAR) launch facility. During the test launch AJAKS suffered a PIRM malfunction and the main parachute did not deploy. Following the test launch, the second stage of the rocket was rebuilt with a stronger payload configuration. The ESRA IREC was held on June 21st to the 24th. AJAKS was launched on the 23rd and during ascent the second stage became unstable and reached an altitude of only 6,000 ft. Both stages suffered damage upon landing.

Increasing Launch Rate and Payload Capabilities
Aerial Launch Vehicles: Increasing Launch Rate and Payload Capabilities Yves Tscheuschner1 and Alec B. Devereaux2 University of Colorado, Boulder, Colorado Two of man's greatest achievements have been the first flight at Kitty Hawk and pushing into the final frontier that is space. Air launch systems aim to combine these great achievements into a revolutionary way to deliver satellites, cargo and eventually people into space. Launching from an aircraft has many advantages, including the ability to launch at any inclination and from above bad weather, which could delay ground launches. While many concepts for launching rockets from an airplane have been developed, very few have made it past the drawing board. Only the Pegasus and, to a lesser extent, SpaceShipOne have truly shown the feasibility of such a system. However, a recent push for rapid, small payload to orbit launches by the military and a general need for cheaper, heavy lift options are leading to an increasing interest in air launch methods. In order for the efficiency and flexibility of the system to be realized, however, additional funding and research are necessary. Nomenclature ALASA = airborne launch assist space access ALS = air launch system DARPA = defense advanced research project agency LEO = low Earth orbit LOX = liquid oxygen RP-1 = rocket propellant 1 MAKS = Russian air launch system MECO = main engine cutoff SS1 = space ship one SS2 = space ship two I. Introduction W hat typically comes to mind when considering launching people or satellites to space are the towering rocket poised on the launch pad. These images are engraved in the minds of both the public and scientists alike.

In the early 1980s, NASA halted procurement at Delta 183 after shifting all payloads to the Space Transportation System. To create Delta II for the U.S. Air Force Medium Launch Vehicle (MLV) program after the 1986 Challenger accident, McDonnell Douglas had to restart Delta production. The new rocket's first stage was stretched 3.66 meters and it's payload fairing was widened. The ultimate Delta II version, which did not appear until 1990, was boosted by more powerful solid rocket motors and a more powerful first stage motor. Delta 184, the first Delta II, launched GPS 14 on Valentine's Day, 1989. Boeing used a four-digit numbering system to identify specific Delta models. The first digit indicated the first stage and solid rocket motor (SRM) type. The first Delta II models, 16 altogether, were 6000-series birds with Extra Long Extended Tank (XLET) Thor first stages, with a Rocketdyne RS-27A main engine, and with Thiokol Castor 4A SRMs. Subsequent 7000-series Delta II vehicles used more powerful Alliant Graphite Epoxy SRMs (GEMs).

NASA SP-IO Office of Scientific and Technical Information NA110NAl AERONAUTICS AND SPACE ADMINISTRATION Washington, D.C. • November 1962 front (over: Atlas-Agena B INTRODUCTION THE space research pro gram of the United States, leading in the years just ahead to manned exploration of the moon, and in the more distant future to manned exploration of the near planets, turns on the ability of our scientists and en gineers to provide the means for p'ropelling useful pay loads through the earth's enveloping atmosphere and into the void of space. For this task, launch vehicles of a number of sizes and capabilities are necessary. Con sequently, the United States is developing a family of launch vehicles ranging in size and power from the slender Scout to the giant Nova. Obviously, it would be unwise to use a ten-ton truck to carry a few parcels or to risk a break-down by overloading a small truck. Similarly, it would be im practicable to use Saturn or Nova to orbit a small, light weight group of scientific instruments, or take the risk of failure involved in placing too much weight on any size rocket. Either would be expensive and inefficient. By developing a family of reliable launch vehicles, the Nation will have available the right size for the right job and avoid the expense of employing vehicles that are either larger and more powerful than necessary, or are marginal in power for the job at hand. [ I ] • For each of the nation's launch vehicles, missions have been assigned. These missions range from scientific research and exploration to tasks vitally necessary for the national defense.
