This report describes and analyzes my work as a technical writer for Analex Corporation during my 16-week Master of Technical and Scientific Communication internship period. Analexs Cleveland branch works in the aerospace industry and primarily contracts for NASAs Glenn Research Center. This report details my work on two projects during this time: Combustion Module-2 (CM-2) and Fluids and Combustion Facility (FCF). For the CM-2 project, I wrote procedures for astronauts to run combustion science experiments on board the space shuttle. For the FCF project, I edited requirements documents for experiment hardware that will be on board the International Space Station. This report discusses background information for each project and analyzes my writing and editing processes in terms of the Anderson Problem-Solving Model for technical communication. The final chapter describes my learning experiences and how these experiences contributed to my development as a technical communicator.
