Strategies for Launch and Assembly of Modular Spacecraft

NASA’s human lunar and Mars exploration program requires a new transportation system between Earth and the Moon or Mars. In recent years, unfortunately, human space exploration programs have faced myriad political, technical, and financial difficulties. In order to avoid such problems, future human space exploration programs should be designed from the start for affordability. This thesis addre...

Survey of Command Execution Systems for NASA Spacecraft and Robots

NASA spacecraft and robots operate at long distances from Earth. Command sequences generated manually, or by automated planners on Earth, must eventually be executed autonomously on-board the spacecraft or robot. Software systems that execute commands on-board are known variously as execution systems, virtual machines, or sequence engines. Every robotic system requires some sort of execution sy...

The Spacecraft SHM Experiment, Part 2: Integration, Challenges and Early Ground Science

The Spacecraft Structural Health Monitoring experiment began development in 20132014 for integration onto two separate flight experiments. Last year’s publication focused on the development and preliminary testing for setting operational and science objective. This year the hardware has been integrated and ground measurements on the STP-H5 payload have begun. The goal for this hardware is ident...
