Vulcan Centaur
VULCAN CENTAUR The Vulcan Centaur rocket design leverages the flight-proven success of the Delta IV and Atlas V launch vehicles while introducing new technologies and innovative features to ensure a reliable and aordable space launch service. Vulcan Centaur will service a diverse range of markets including 225 ft commercial, civil, science, cargo and national security space customers. 1 The spacecraft is encapsulated in a 5.4-m- (17.7-ft-) diameter payload fairing (PLF), a sandwich composite structure made with a vented aluminum-honeycomb core and graphite-epoxy face sheets. The bisector (two-piece shell) PLF encapsulates the spacecraft. The payload attach fitting (PAF) is a similar sandwich composite structure creating the mating interface from spacecraft to second stage. The PLF separates using a debris-free horizontal and vertical separation system with 2 200 ft spring packs and frangible joint assembly. The payload fairing is available in the 15.5-m (51-ft) standard and 21.3-m (70-ft) 1 long configurations. The Centaur upper stage is 5.4 m (17.7 ft) in diameter and 3 11.7 m (38.5 ft) long with a 120,000-lb propellant capacity. Its propellant tanks are constructed of pressure-stabilized, corrosion-resistant stainless steel. Centaur is a liquid hydrogen/liquid oxygen-fueled vehicle, with two RL10C 4 engines. The Vulcan Centaur Heavy vehicle, flies the upgraded 2 Centaur using RL10CX engines with nozzle extensions. The 5 175 ft cryogenic tanks are insulated with spray-on foam insulation (SOFI) to manage boil o of cryogens during flight. An aft equipment shelf provides the structural mountings for vehicle electronics. -

H-SC Journal of Sciences (2017) Vol. VI Thomas Mars: A prospect for settlement Mitchell H. Thomas’17 Department of Biology, Hampden-Sydney College, Hampden-Sydney, VA 23943 The exploration of Mars was once left to the imagination. However, in recent years, the topic of exploring Mars has become more realistic and increasingly popular in news articles and scientific communities. Technology developed in the previous half-century have already allowed humans to send rovers to Mars in order to retrieve some basic data about the planet. Current technological advancements are resulting in reusable rockets that could one day travel between Earth and Mars. Exploration and colonization of Mars are important for the development of research on the planet and the search for life. Current data is limited, but shows that the conditions on Mars could have supported life in the past. To further our knowledge of the red planet, The atmosphere surrounding Earth is nearly organizations like NASA and companies like SpaceX one-hundred times denser than that of Mars and its are developing plans to colonize Mars. Many composition is crucial to life. According to NASA, the obstacles stand in the way before humans can reach Earth’s atmosphere is comprised of 78% Nitrogen, and colonize the red planet. However, Mars is the 21% Oxygen, and 1% Other.

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. -

DLR is performing an extensive study on return methods for a reusable booster stage for a future launch vehicle. The present study focuses on the vertical take-off and vertical landing (VTOL) method. First, a restitution of a flight of Falcon 9 is presented in order to assess the accuracy of the tools used. Then, the preliminary designs of different variants of a future Ariane launch vehicle with a reusable VTOL booster stage are described. The proposed launch vehicle is capable of launching a seven ton satellite into a geostationary transfer orbit (GTO) from the European spaceport in Kourou. Different stagings and propellants (LOx/LH2, LOx/LCH4, LOx/LC3H8, subcooled LOx/LCH4) are considered, evaluated and compared. First sizing of a broad range of launcher versions are based on structural index derived from existing stages. -

Gordan Lewis Research Center Cleveland, Ohio January 1987 . CENTAUR D1-A SYSTEMS IN A NUTSHELL Andrew L. Gordan National Aeronautics and Space Administration Lewis Research Center Cleveland, Ohio 44135 SUMMARY This report identifies the unique aspects of the Centaur D1-A systems and subsystems. Centaur performance is described in terms of optimality (pro- pellant usage), flexibility, and airborne computer requirements. Major I-. systems are described narratively with some numerical data given where it may 03 CJ be useful. v, I W INTRODUCT ION The Centaur D1-A launch vehicle continues to be a key element in the Nation's space program. The Atlas/Centaur and Titan/Centaur combinations have boosted into orbit a variety of spacecraft on scientific, lunar, and planetary exploration missions and Earth orbit missions. These versatile, reliable, and accurate space booster systems will contribute to many significant space pro- grams well into the shuttle era. Centaur D1-A is the latest version of the Nation's first high-energy cryogenic launch vehicle. Major improvements in avionics and payload struc- ture have enhanced mission flexibility and mission success reliability. The liquid hydrogen and liquid oxygen propellants and the pressurized stainless steel structure provide a top-performance vehicle. Centaur's primary thrust comes from two Pratt 8, Whitney constant- thrust, turbopump-fed, regeneratively cooled, liquid-fueled rocket engines. Each RL10A-3-3a engine can generate 16 500 lb of thrust, for a total thrust of 33 000 lb. -

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.
