Trajectory Control Programs in Support of Apollo Missions
the trajectory of a spacecraft in flight has been predicted, control measures are required to ensure that the trajectory data is applied in a consistent manner when calculating the many trajectory-related parameters required by the flight controllers of the space fligh t. This paper describes the queue control techniques used in generating the predicted trajectory and the subsequent use of the ...
متن کاملSpeech activity detection for NASA apollo space missions: challenges and solutions
Speech Activity Detection(SAD) is a well researched problem for communication, command and control applications, where audio segments are short duration and solution proposed for noisy as well as clean environments. In this study, we investigate the SAD problem using NASA’s Apollo space mission data [1]. Unlike traditional speech corpora, the audio recordings in Apollo are extensive from a long...
متن کاملGuide to the Apollo Collection
The Saturn C-1 Heavy space vehicle will be launched experimentally this fall for the first time. In this first firing of the three stage rocket, only the booster will be "live" and it will be operating at a thrust somewhat lower (12%) than that planned for later Saturns Series 5 High Water Project
متن کاملThe Bidirectional Reflectance of Apollo
Introduction: Accurate models of the lunar thermal and illumination environment require a realistic treatment of scattered radiation at high incidence and emission angles. It has long been appreciated that the bidirectional reflectance of lunar soil is anisotropic [1], yet most lunar thermal models still assume that scattered radiation is isotropic. We recently measured the bidirectional reflec...
متن کاملThe scientific legacy of Apollo
This December marks 40 years since Gene Cernan and Harrison “Jack” Schmitt of Apollo 17 left the lunar surface and returned safely to Earth. This anniversary has been given additional poignancy by the death earlier this year of Neil Armstrong, the first man to set foot on the Moon with Apollo 11 in July 1969. The history of the Apollo project, and its geopolitical motivation within the context ...
