Gryphon: a Flexible Lunar Lander Design to Support a Semi-Permanent Lunar Outpost
AIAA SPACE 2007 Conference & Exposition AIAA 2007-6169 18 - 20 September 2007, Long Beach, California The Gryphon: A Flexible Lunar Lander Design to Support a Semi-Permanent Lunar Outpost Dale Arney1, Joseph Hickman,1 Philip Tanner,1 John Wagner,1 Marc Wilson,1 and Dr. Alan Wilhite2 Georgia Institute of Technology/National Institute of Aerospace, Hampton, VA, 23666 A lunar lander is designed to provide safe, reliable, and continuous access to the lunar surface by the year 2020. The NASA Exploration System Architecture is used to initially define the concept of operations, architecture elements, and overall system requirements. The design evaluates revolutionary concepts and technologies to improve the performance and safety of the lunar lander while minimizing the associated cost using advanced systems engineering capabilities and multi-attribute decision making techniques. The final design is a flexible (crew and/or cargo) lander with a side-mounted minimum ascent stage and a separate stage to perform lunar orbit insertion.

Apollo 11 Astronaut Neil Armstrong Broadcast from the Moon (July 21, 1969) Added to the National Registry: 2004 Essay by Cary O’Dell
Apollo 11 Astronaut Neil Armstrong Broadcast from the Moon (July 21, 1969) Added to the National Registry: 2004 Essay by Cary O’Dell “One small step for…” Though no American has stepped onto the surface of the moon since 1972, the exiting of the Earth’s atmosphere today is almost commonplace. Once covered live over all TV and radio networks, increasingly US space launches have been relegated to a fleeting mention on the nightly news, if mentioned at all. But there was a time when leaving the planet got the full attention it deserved. Certainly it did in July of 1969 when an American man, Neil Armstrong, became the first human being to ever step foot on the moon’s surface. The pictures he took and the reports he sent back to Earth stopped the world in its tracks, especially his eloquent opening salvo which became as famous and as known to most citizens as any words ever spoken. The mid-1969 mission of NASA’s Apollo 11 mission became the defining moment of the US- USSR “Space Race” usually dated as the period between 1957 and 1975 when the world’s two superpowers were competing to top each other in technological advances and scientific knowledge (and bragging rights) related to, truly, the “final frontier.” There were three astronauts on the Apollo 11 spacecraft, the US’s fifth manned spaced mission, and the third lunar mission of the Apollo program. They were: Neil Armstrong, Edwin “Buzz” Aldrin, and Michael Collins. The trio was launched from Kennedy Space Center in Florida on July 16, 1969 at 1:32pm. -
Materials for Liquid Propulsion Systems
https://ntrs.nasa.gov/search.jsp?R=20160008869 2019-08-29T17:47:59+00:00Z CHAPTER 12 Materials for Liquid Propulsion Systems John A. Halchak Consultant, Los Angeles, California James L. Cannon NASA Marshall Space Flight Center, Huntsville, Alabama Corey Brown Aerojet-Rocketdyne, West Palm Beach, Florida 12.1 Introduction Earth to orbit launch vehicles are propelled by rocket engines and motors, both liquid and solid. This chapter will discuss liquid engines. The heart of a launch vehicle is its engine. The remainder of the vehicle (with the notable exceptions of the payload and guidance system) is an aero structure to support the propellant tanks which provide the fuel and oxidizer to feed the engine or engines. The basic principle behind a rocket engine is straightforward. The engine is a means to convert potential thermochemical energy of one or more propellants into exhaust jet kinetic energy. Fuel and oxidizer are burned in a combustion chamber where they create hot gases under high pressure. These hot gases are allowed to expand through a nozzle. The molecules of hot gas are first constricted by the throat of the nozzle (de-Laval nozzle) which forces them to accelerate; then as the nozzle flares outwards, they expand and further accelerate. It is the mass of the combustion gases times their velocity, reacting against the walls of the combustion chamber and nozzle, which produce thrust according to Newton’s third law: for every action there is an equal and opposite reaction. [1] Solid rocket motors are cheaper to manufacture and offer good values for their cost. -

4. Lunar Architecture
4. Lunar Architecture 4.1 Summary and Recommendations As defined by the Exploration Systems Architecture Study (ESAS), the lunar architecture is a combination of the lunar “mission mode,” the assignment of functionality to flight elements, and the definition of the activities to be performed on the lunar surface. The trade space for the lunar “mission mode,” or approach to performing the crewed lunar missions, was limited to the cislunar space and Earth-orbital staging locations, the lunar surface activities duration and location, and the lunar abort/return strategies. The lunar mission mode analysis is detailed in Section 4.2, Lunar Mission Mode. Surface activities, including those performed on sortie- and outpost-duration missions, are detailed in Section 4.3, Lunar Surface Activities, along with a discussion of the deployment of the outpost itself. The mission mode analysis was built around a matrix of lunar- and Earth-staging nodes. Lunar-staging locations initially considered included the Earth-Moon L1 libration point, Low Lunar Orbit (LLO), and the lunar surface. Earth-orbital staging locations considered included due-east Low Earth Orbits (LEOs), higher-inclination International Space Station (ISS) orbits, and raised apogee High Earth Orbits (HEOs). Cases that lack staging nodes (i.e., “direct” missions) in space and at Earth were also considered. This study addressed lunar surface duration and location variables (including latitude, longi- tude, and surface stay-time) and made an effort to preserve the option for full global landing site access. Abort strategies were also considered from the lunar vicinity. “Anytime return” from the lunar surface is a desirable option that was analyzed along with options for orbital and surface loiter. -

A Launch Pad Escape System for Human Spaceflight Is One of Those Things That Everyone Hopes They Will Never Need but Is Critical for Every Manned Space Program
https://ntrs.nasa.gov/search.jsp?R=20110012275 2019-08-30T15:55:02+00:00Z Launch Pad Escape System Design (Human Spaceflight): -Kelli Maloney A launch pad escape system for human spaceflight is one of those things that everyone hopes they will never need but is critical for every manned space program. Since men were first put into space in the early 1960s, the need for such an Emergency Escape System (EES) has become apparent. The National Aeronautics and Space Administration (NASA) has made use of various types ofthese EESs over the past 50 years. Early programs, like Mercury and Gemini, did not have an official launch pad escape system. Rather, they relied on a Launch Escape System (LES) of a separate solid rocket motor attached to the manned capsule that could pull the astronauts to safety in the event of an emergency. This could only occur after hatch closure at the launch pad or during the first stage of flight. A version of a LES, now called a Launch Abort System (LAS) is still used today for all manned capsule type launch vehicles. However, this system is very limited in that it can only be used after hatch closure and it is for flight crew only. In addition, the forces necessary for the LES/LAS to get the capsule away from a rocket during the first stage of flight are quite high and can cause injury to the crew. These shortcomings led to the development of a ground based EES for the flight crew and ground support personnel as well. -
Preliminary Study for Manned Spacecraft with Escape System and H-IIB Rocket
Trans. JSASS Space Tech. Japan Vol. 7, No. ists26, pp. Tg_35-Tg_44, 2009 Preliminary Study for Manned Spacecraft with Escape System and H-IIB Rocket By Takane IMADA, Michio ITO, Shinichi TAKATA Japan Aerospace Exploration Agency ,Tsukuba, Japan (Received April 30th, 2008) HTV (H-II Transfer Vehicle) is the first Japanese un-manned service vehicle that will transport several pieces of equipments to ISS (International Space Station) and support human activities on orbit. HTV will be launched by the first H-IIB rocket in September 2009 and JAXA will have the capability to access LEO (Low Earth Orbit) bases with enough volume/weight as the human transport system. This paper is the preliminary study for developing a manned spacecraft from the HTV design and includes clarification of necessary development items. In addition, missing parts in the current HTV design are identified with some analysis, such as LES (Launch Escape System), which is mandatory for all human transport systems. Keyword: Manned Transportation, H-II, HTV, Escape System 1.
