The DebriSat project is a collaboration of the NASA Orbital Debris Program Office, the Air Force Space and Missile Systems Center, The Aerospace Corporation, the University of Florida, and the Air Force Arnold Engineering Development Complex. The project's goal is to design and fabricate a 56-kg class spacecraft mock-up (“DebriSat”) representative of modern payloads in the low Earth orbit environment, conduct a hypervelocity impact test to catastrophically break it up.Primary Duties: • Use lab generated data to update satellite breakup models and improving situational awareness in Low Earth Orbit • Coordinate activity of DebriSat employees, define and prioritize workload • Perform continuous improvements in MATLAB for independently designed 2-D and 3-D imaging systems • Collect, characterize and archive fragments generated from the DebriSat hypervelocity impact test Projects: 3D Imager Optimization• Optimized MATLAB code in a team of four to implement object renderings, calculations and calibration techniques of a 3-D imaging system• Utilized SolidWorks to create hardware components• Implemented MS Excel to analyze data and documented progress in MS Word DebriSat Foam Separation Project• Led a team of three through the design process of a system to filter small pieces of satellite from foam dust. • Utilized SOLIDWORKS to design and draft the system. • Documented the results and findings in Microsoft Word and Excel.

Primary Duties: • Aided in ownership of Gas Turbine 9FA class blades throughout the complete serial production and reconditioning life cycle• Utilized analytical methods and design analysis tools such as GOM to influence manufacturing and process operations and establish acceptance criteria for the manufacturing of airfoils• Coordinated with outside vendors in the US, global consumers in Japan and internal groups to develop manufacturing process for existing airfoil products according to the technical and program requirements• Provided input into the new design components for manufacturability and reparability• Dispositioned non-conforming products and work to eliminate the root cause of the issue for future orders• Defined and implemented new processes for 7FA and 501F Gas Turbine compressor airfoil manufacturing• Provided updates to specifications and created Work Instructions for standardized practices

The purpose of the DebriSat project is to improve space situational awareness in lower Earth orbit (LEO) through better understanding of the debris environment. Because of the increasing use of new materials, fragments generated from orbital collisions of modern-built spacecraft do not accurately fit prior models. To date, the focus of the DebriSat program was to build a comprehensive database of the mass, material, geometric and radar & optical properties of the fragments generated by these collisions. This internship was to build an alternative means to analyze the entire explosion of a single satellite quickly and thoroughly.Accomplishments: • Developed a MATLAB X-ray image processing algorithm to identify and measure satellite debris generated from a hypervelocity impact test • Worked with vector geometry and transform matrices to statistically represent data collected from X-ray images • Used statistical representations to model size, shape, and radar and optical properties of debris items • Identified areas of a test chamber with dense clusters of debris and prioritized a manual data collection process to reduce project cost• Constructed 3-D databases in MATLAB to analyze the anisotropy of the breakup plume and track fragment locations• Build a software engine in MATLAB to cross-reference X-ray fragments to an existing 2-D database• Analyze how satellite debris generated from a hypervelocity impact test was affected by its containment environment

Duties included: Email communication, print exams and quizzes, organize office spaces, file student records.

DUTIES:Prepare meeting agendas, lead chapter meetings, appoint and establish necessary committees, develop goals for the chapter with help from other officers and advisers, oversee chapter projects and award preparation. Skillfully motivate the chapter members, conduct executive board meetings on a weekly basis,conduct new member orientation and coordinate new member induction, make sure the chapter volunteer efforts are completed,Represent the chapter at regional meetings and events.ACCOMPLISHMENTS: I led an in-depth research project on the lasting effects of BP's Gulf of Mexico oil spill on marine life and habitat. Discoveries were made that the spill had serious lasting effects. I led a presentation to inform the public of the existing dangers and urged them to take action. Increased involvement of the chapter from less than 10 members to over 30. I achieved this by conducting weekly meetings that discussed the duties of the chapter and informed the students of the opportunities and resources available to them. My main idea was to make the chapter a more inclusive environment for students and provide them with the skills they needed to succeed at their current career level. This in turn provided more man power to the chapter and more efficient work was submitted in the annual review. RELATED SKILLS:Leadership, communication, team building, creativity, time management.
