7. Operations
7. Operations 7.1 Ground Operations The Exploration Systems Architecture Study (ESAS) team addressed the launch site integra- tion of the exploration systems. The team was fortunate to draw on expertise from members with historical and contemporary human space flight program experience including the Mercury, Gemini, Apollo, Skylab, Apollo Soyuz Test Project, Shuttle, and International Space Station (ISS) programs, as well as from members with ground operations experience reaching back to the Redstone, Jupiter, Pershing, and Titan launch vehicle programs. The team had a wealth of experience in both management and technical responsibilities and was able to draw on recent ground system concepts and other engineering products from the Orbital Space Plane (OSP) and Space Launch Initiative (SLI) programs, diverse X-vehicle projects, and leadership in NASA/Industry/Academia groups such as the Space Propulsion Synergy Team (SPST) and the Advanced Spaceport Technology Working Group (ASTWG). 7.1.1 Ground Operations Summary The physical and functional integration of the proposed exploration architecture elements will occur at the primary launch site at the NASA Kennedy Space Center (KSC). In order to support the ESAS recommendation of the use of a Shuttle-derived Cargo Launch Vehicle (CaLV) and a separate Crew Launch Vehicle (CLV) for lunar missions and the use of a CLV for ISS missions, KSC’s Launch Complex 39 facilities and ground equipment were selected for conversion. Ground-up replacement of the pads, assembly, refurbishment, and/or process- ing facilities was determined to be too costly and time-consuming to design, build, outfit, activate, and certify in a timely manner to support initial test flights leading to an operational CEV/CLV system by 2011. -

53Rd IAA HISTORY of ASTRONAUTICS SYMPOSIUM (E4) “Can You Believe They Put a Man on the Moon?” the Apollo Program
70th International Astronautical Congress 2019 Paper ID: 48885 oral 53rd IAA HISTORY OF ASTRONAUTICS SYMPOSIUM (E4) \Can you believe they put a man on the moon?" The Apollo Program. (3) Author: Mr. John Goodman Odyssey Space Research, United States, [email protected] DORIS CHANDLER AND THE SATURN V GUIDANCE DEBATE Abstract Doris Chandler was a NASA engineer who led the team of men who developed the on-board guidance algorithm used by the Saturn launch vehicles. She received a B.S. in Mathematics from Tulane University with a Phi Beta Kappa Key and joined the Aeroballistics Laboratory at the Redstone Arsenal in 1953. As a NASA employee at the Marshall Space Flight Center in the 1960s, she served in three management positions: Deputy Chief of the Guidance Theory Section, Chief of the Guidance Application Section, and Chief of the Applied Guidance and Flight Mechanics Branch. In the early 1960s, Doris Chandler's team developed one of two competing mathematical concepts for Saturn guidance. The advent of flyable digital computers permitted the development of software- based guidance algorithms. Reference trajectory guidance methods employing analog computing, used for ballistic missiles in the 1950s, were not suitable for new space launch vehicles like the Saturn V. The Polynomial Guidance Mode (PGM), championed by Peenem¨undeveteran Rudolf Hoelker, used guidance polynomials derived from curve fits of nominal and dispersed optimal trajectories computed using the calculus of variations. PGM required extensive pre-flight computation but resulted in simple on-board software. Doris Chandler's team developed the Iterative Guidance Mode (IGM) based on an idea of Peenem¨unde veteran Helmut Horn that involved Lawden's linear tangent steering law. -
A Pictorial History of Rockets
he mighty space rockets of today are the result A Pictorial Tof more than 2,000 years of invention, experi- mentation, and discovery. First by observation and inspiration and then by methodical research, the History of foundations for modern rocketry were laid. Rockets Building upon the experience of two millennia, new rockets will expand human presence in space back to the Moon and Mars. These new rockets will be versatile. They will support Earth orbital missions, such as the International Space Station, and off- world missions millions of kilometers from home. Already, travel to the stars is possible. Robotic spacecraft are on their way into interstellar space as you read this. Someday, they will be followed by human explorers. Often lost in the shadows of time, early rocket pioneers “pushed the envelope” by creating rocket- propelled devices for land, sea, air, and space. When the scientific principles governing motion were discovered, rockets graduated from toys and novelties to serious devices for commerce, war, travel, and research. This work led to many of the most amazing discoveries of our time. The vignettes that follow provide a small sampling of stories from the history of rockets. They form a rocket time line that includes critical developments and interesting sidelines. In some cases, one story leads to another, and in others, the stories are inter- esting diversions from the path. They portray the inspirations that ultimately led to us taking our first steps into outer space. NASA’s new Space Launch System (SLS), commercial launch systems, and the rockets that follow owe much of their success to the accomplishments presented here. -

Apollo 1, known at that time as AS (Apollo Saturn)-204 would be the first manned spaceflight of the Apollo program, and would launch a few months after the flight of Gemini 12, which had occurred on 11 November 1966. Although Gemini 12 was a short duration flight, Pilot Buzz Aldrin had performed three extensive EVA’s (Extra Vehicular Activities), proving that Astronauts could work for long periods of time outside the spacecraft. -
