Canoga Park, California. Soon after being hired, she was promoted to the role of Theoretical Performance Specialist, which required her to mathematically calculate the expected performance of new rocket propellants. Out of 900 engineers, she was the only woman, and one of only a few without a college degree. While working at North American Aviation, she met her future husband, George Richard Morgan, a Mechanical Engineering graduate from Caltech. Together, they had four children – George, Stephen, Monica, and Karen. Space race era During the development program for the Jupiter missile, Wernher von Braun's team used modified Redstone missiles, dubbed the Jupiter C, to accelerate the rocket to orbital velocities. In order to improve the performance of the first stage, they awarded a contract to North American Aviation's Rocketdyne Division to come up with a more powerful fuel. Morgan was assigned to lead a group of college interns at North American Aviation's Rocketdyne Division. Due to her expertise and experience, Morgan's work resulted in the birth of a new propellant, Hydyne. The standard Redstone was fueled with a 75% ethyl alcohol solution, but the Jupiter-C first stage had used Hydyne fuel, a blend of 60% unsymmetrical dimethylhydrazine (UDMH) and 40% diethylenetriamine (DETA). This was a more powerful fuel than ethyl alcohol. The first Hydyne-powered Redstone R&D flight took place on 29 November 1956, and Hydyne subsequently powered three Jupiter C nose cone test flights. In 1957, the Soviet Union and the United States had set a goal of placing satellites into Earth orbit as part of a worldwide scientific celebration, known as the International Geophysical Year. In this endeavor, the United States' effort was called Project Vanguard. The Soviet Union successfully launched the Sputnik satellite on October 4, 1957, an event followed soon after by a very public and disastrous explosion of a Vanguard rocket. Political pressure forced U.S. politicians to allow a former German rocket scientist, Wernher von Braun, to prepare his Jupiter C rocket for an orbital flight. In the renamed launcher (now called Juno I), the propellant succeeded in launching America's first satellite, Explorer I, into orbit on January 31, 1958. After the Jupiter C and six Juno I launches, the U.S. switched to more powerful fuels. Proposed fuel name As Hydyne-LOX (liquid oxygen) was the fuel combination used for the Redstone rocket, Morgan whimsically suggested naming her new fuel formulation "Bagel", since the rocket's propellant combination
