ULA Atlas V Launch to Feature Full Complement of Aerojet Rocketdyne Solid Rocket Boosters
April 13, 2018 ULA Atlas V Launch to Feature Full Complement of Aerojet Rocketdyne Solid Rocket Boosters SACRAMENTO, Calif., April 13, 2018 (GLOBE NEWSWIRE) -- The upcoming launch of the U.S. Air Force Space Command (AFSPC)-11 satellite aboard a United Launch Alliance Atlas V rocket from Cape Canaveral Air Force Station, Florida, will benefit from just over 1.74 million pounds of added thrust from five AJ-60A solid rocket boosters supplied by Aerojet Rocketdyne. The mission marks the eighth flight of the Atlas V 551 configuration, the most powerful Atlas V variant that has flown to date. The Atlas V 551 configuration features a 5-meter payload fairing, five AJ-60As and a Centaur upper stage powered by a single Aerojet Rocket RL10C-1 engine. This configuration of the U.S. government workhorse launch vehicle is capable of delivering 8,900 kilograms of payload to geostationary transfer orbit (GTO), and also has been used to send scientific probes to explore Jupiter and Pluto. The Centaur upper stage also uses smaller Aerojet Rocketdyne thrusters for pitch, yaw and roll control, while both stages of the Atlas V employ pressurization vessels built by Aerojet Rocketdyne's ARDÉ subsidiary. "The Atlas V is able to perform a wide variety of missions for both government and commercial customers, and the AJ-60A is a major factor in that versatility," said Aerojet Rocketdyne CEO and President Eileen Drake. "Aerojet Rocketdyne developed the AJ-60A specifically for the Atlas V, delivering the first booster just 42 months after the contract award, which underscores our team's ability to design and deliver large solid rocket motors in support of our nation's strategic goals and efforts to explore our solar system." The flight of the 100th AJ-60A, the largest monolithically wound solid rocket booster ever flown, took place recently as part of a complement of four that helped an Atlas V 541 place the nation's newest weather satellite into GTO. -

Starliner Rudolf Spoor Vertregt-raket Van de hoofdredacteur: Ook de NVR ontsnapt niet aan de gevolgen van het Corona- virus: zoals u in de nieuwsbrief heeft kunnen lezen zijn we genoodzaakt geweest de voor maart, april en mei geplande evenementen op te schorten. In de tussentijd zijn online ruimtevaart-gerelateerde initiatieven zeer de moeite waard om te volgen, en in de nieuwsbrief heeft u daar ook een overzicht van kunnen vinden. De redactie heeft zijn best gedaan om ook in deze moeilijke tijden voor u een afwisselend nummer samen te stellen, met onder andere aandacht voor de lancering van de eerste Starliner, een studentenproject waarin een supersone para- Bij de voorplaat chute getest wordt, tests van een prototype maanrover op het DECOS terrein in Noordwijk en een uitgebreide analyse Kunstzinnige weergave van de lancering van de Vertregt-raket vanuit met moderne middelen van het Vertregt raketontwerp uit de Suriname.

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. -

Arnaldi et al.: Human Behavior During Spaceflight - Evidence From an Analog Environment Introduction Four years after the launch of Sputnik, the world’s first artificial satellite, Yuri Gagarin became the first human to reach space (National Aeronautics and Space Administration [NASA], 2011a). The United States soon followed on the path of manned space exploration with Project Mercury. Although this program began with suborbital flights, manned spacecraft were subsequently launched into orbit around the Earth (NASA, 2012). With President Kennedy setting the goal of landing a man on the moon, NASA focused on short-duration orbital flights as a stepping-stone to lunar missions. -

Atlas V Cutaway Poster
ATLAS V Since 2002, Atlas V rockets have delivered vital national security, science and exploration, and commercial missions for customers across the globe including the U.S. Air Force, the National Reconnaissance Oice and NASA. 225 ft The spacecraft is encapsulated in either a 5-m (17.8-ft) or a 4-m (13.8-ft) diameter payload fairing (PLF). The 4-m-diameter PLF is a bisector (two-piece shell) fairing consisting of aluminum skin/stringer construction with vertical split-line longerons. The Atlas V 400 series oers three payload fairing options: the large (LPF, shown at left), the extended (EPF) and the extra extended (XPF). The 5-m PLF is a sandwich composite structure made with a vented aluminum-honeycomb core and graphite-epoxy face sheets. The bisector (two-piece shell) PLF encapsulates both the Centaur upper stage and the spacecraft, which separates using a debris-free pyrotechnic actuating 200 ft system. Payload clearance and vehicle structural stability are enhanced by the all-aluminum forward load reactor (FLR), which centers the PLF around the Centaur upper stage and shares payload shear loading. The Atlas V 500 series oers 1 three payload fairing options: the short (shown at left), medium 18 and long. 1 1 The Centaur upper stage is 3.1 m (10 ft) in diameter and 12.7 m (41.6 ft) long. Its propellant tanks are constructed of pressure-stabilized, corrosion-resistant stainless steel. Centaur is a liquid hydrogen/liquid oxygen-fueled vehicle. It uses a single RL10 engine producing 99.2 kN (22,300 lbf) of thrust. -

By establishing government-industry partnerships, the Commercial Orbital Transportation Services (COTS) program marked a change from the traditional way NASA had worked. Inset photos, right: The COTS program supported two U.S. companies in their efforts to design and build transportation systems to carry cargo to low-Earth orbit. (Top photo—Credit: SpaceX) SpaceX launched its Falcon 9 rocket on May 22, 2012, from Cape Canaveral, Florida. (Second photo) Three days later, the company successfully completed the mission that sent its Dragon spacecraft to the Station. (Third photo—Credit: NASA/Bill Ingalls) Orbital Sciences Corp. sent its Antares rocket on its test flight on April 21, 2013, from a new launchpad on Virginia’s eastern shore. Later that year, the second Antares lifted off with Orbital’s cargo capsule, (Fourth photo) the Cygnus, that berthed with the ISS on September 29, 2013. Both companies successfully proved the capability to deliver cargo to the International Space Station by U.S. commercial companies and began a new era of spaceflight.

Dual Thrust Axis Lander (DTAL) Lands Horizontally
Robust Lunar Exploration Using an Efficient Lunar Lander Derived from Existing Upper Stages AIAA 2009-6566 Bernard F. Kutter 1, Frank Zegler 2, Jon Barr 3, Tim Bulk 4, Brian Pitchford 5 United Launch Alliance Denver, CO Future large scale lunar exploration is impeded by the high cost of accessing the lunar surface. This cost is composed of terrestrial launch costs and the cost of developing and operating efficient lunar landers capable of delivering crew and large payloads to the lunar surface. Developing lunar landers from a platform based upon an operational upper stage minimizes development and recurring costs while increasing crew safety and reliability. The Dual Thrust Axis Lander (DTAL) lands horizontally. It uses an RL10 engine to accomplish the descent deceleration to just above the lunar surface. Final landing is accomplished using thrusters mounted along the DTAL body. This configuration places the crew and payloads safely and conveniently close to the lunar surface. This paper describes DTAL and its benefits in supporting a robust lunar exploration program. Initial DTAL-enabled large robotic missions allow NASA to return to the moon quickly and demonstrate hardware to be used by crews that follow. This same mission design supports placement of large lunar base elements (habitats, power plants, rovers, excavation equipment, etc). As the uncrewed missions are completed, and the system matures, astronauts will then use the same, now proven system to access the lunar surface. The reliable DTAL propulsion stage provides the flexibility to visit destinations other than the moon. DTAL’s mass and thermal efficient design provides the capability to visit NEO’s or possibly even Mars. -
The Evolving Launch Vehicle Market Supply and the Effect on Future NASA Missions
Presented at the 2007 ISPA/SCEA Joint Annual International Conference and Workshop - www.iceaaonline.com The Evolving Launch Vehicle Market Supply and the Effect on Future NASA Missions Presented at the 2007 ISPA/SCEA Joint International Conference & Workshop June 12-15, New Orleans, LA Bob Bitten, Debra Emmons, Claude Freaner 1 Presented at the 2007 ISPA/SCEA Joint Annual International Conference and Workshop - www.iceaaonline.com Abstract • The upcoming retirement of the Delta II family of launch vehicles leaves a performance gap between small expendable launch vehicles, such as the Pegasus and Taurus, and large vehicles, such as the Delta IV and Atlas V families • This performance gap may lead to a variety of progressions including – large satellites that utilize the full capability of the larger launch vehicles, – medium size satellites that would require dual manifesting on the larger vehicles or – smaller satellites missions that would require a large number of smaller launch vehicles • This paper offers some comparative costs of co-manifesting single- instrument missions on a Delta IV/Atlas V, versus placing several instruments on a larger bus and using a Delta IV/Atlas V, as well as considering smaller, single instrument missions launched on a Minotaur or Taurus • This paper presents the results of a parametric study investigating the cost- effectiveness of different alternatives and their effect on future NASA missions that fall into the Small Explorer (SMEX), Medium Explorer (MIDEX), Earth System Science Pathfinder (ESSP), Discovery,
