NASA  GODDARD/PGCC  SPACE TECHNOLOGY INSTITUTE   SPACE  ENGINEERING  TECHNOLOGY  Degree Program

 

The Space Engineering Technology program provides students with the range of skills and information needed for successful employment at NASA’s Goddard Space Flight Center (GSFC) and its associated contractors (GCA).  The NASA Goddard/PGCC Space Technology Institute was founded in 1991 under the leadership of Sen. Barbara Mikulski as an educational partnership between the NASA GSFC, the GCA members, and the Prince George’s Community College (PGCC) Department of Engineering Technology. The Space Engineering Technology curriculum was then developed, and selected NASA facilities and expert NASA instructors were selected to support the Institute. The NASA high-technology training facility in Lanham, MD and the GSFC campus in Greenbelt, MD are utilized by the Institute to support the program. This affords the student truly unique access to state-of-the-art facilities and instruction. The curriculum includes specifically NASA-related courses including:  high-reliability soldering /fabrication, fiber optics, satellite communications, space technology/spacecraft operations, electronics, and computer specialty courses.

 

An important curriculum option is the Quality Science program. The Quality Science program is tailored toward quality control, assurance, and management (including the ISO standards). The Quality Assurance program is compatible with suggested American Society for Quality (ASQ) training leading to CQT, CQE, CQA, CQM, CSQE, and CRE certifications. The individual courses cover the recommended ASQ “body of knowledge” and will help anyone working in the quality discipline at any business or governmental agency. 

 

            The Space Engineering Technology program has two goals.  The first is to provide students with the specialized skills needed to attain entry-level employment in the space technology field.  The second goal is to upgrade and enrich the skills of existing Goddard and Goddard contractor employees.  Many of the courses within the program are so specialized that they are not offered by any other local college.  Other courses are more conventional ones that have been modified only slightly to provide them with a space perspective.
