NASA Goddard Facts:

NASA's Goddard Space Flight Center (GSFC), located in Greenbelt, Md., manages many of the space agency's Earth observation, astronomy, and space physics missions.

NASA GSFC was established on May 1, 1959 in memory of an American Rocket Pioneer named Robert H. Goddard.

NASA Goddard Space Flight Center

Power System Electronics Designer

Since 1992, Ms. Amri I. Hernandez-Pellerano has been working for the Power Systems Branch (PSB) at Goddard Space Flight Center (GSFC). She is a Power System Electronics designer and has been involved in the design and implementation of power system electronics (PSE) for various scientific spacecrafts. These include The Tropical Rainfall Measuring Mission (TRMM), the Microwave Anisotropy Probe (MAP), the Earth Observing-1 (EO-1), the Lunar Reconnaissance Observer (LRO) and the Solar Dynamics Observatory (SDO). She has also been part of the Power System for the GPM and MMS missions, currently scheduled to launch in 2013 and 2014 respectively. Another exciting part of her work is her involvement in international collaborations, such as the Aquarius/SAC-D (Satelite de Applicaciones Cientificas D) mission with Argentina, launched in 2011.

She has dedicated most of her career to the design, build and test of the electronics that will regulate the solar array power in order to charge the spacecraft battery and distribute power to the different loads or users inside the spacecraft. This is very challenging and interesting work where she and her team strive to provide state-of-the-art technology for every design. Every mission is different and presents her the opportunity to learn as well as to be creative and put to the test her electrical engineering skills.

She has won numerous performances and team awards for her contributions in the area of Electrical and Power Systems Electronics, most notably the GSFC Engineering Achievement Award and the NASA Exceptional Service Medal.

In addition to her engineering work, she is the chair for the Hispanic Advisory Committee for Employees (HACE) at GSFC. This committee works with the Equal Opportunity Office and, among other responsibilities, serves as a focal point
for the concerns of Hispanic employees on matters affecting their employment at GSFC.

She was born and raised in the island of Puerto Rico. Throughout her school years, she always enjoyed math and science. Her parents encouraged her to pursue a college education and they always emphasized the advantages of obtaining a college degree. She completed her Bachelor’s degree in Electrical Engineering (BSEE) degree at the University of Puerto Rico, Mayaguez Campus. While in college, she had the opportunity to work at GSFC as a summer intern, which led her to recommend to every young student to obtain a summer opportunity in his or her field of interest. Soon after college, she started working at GSFC full time. While working full time, GSFC provided her the opportunity to complete a Masters degree in Electrical Engineering from The Johns Hopkins University.

She has a beautiful and happy family that gives her great joy. In her spare time, she likes making scrap books, baking and hiking. She has found through the years that, although sometimes hard, it is very important to balance work-life and family-life. She is also a member of the Goddard Hispanic Heritage Club at GSFC.

She likes to encourage young people to put a lot of effort into obtaining a college degree in an area of their interest. We can all be creative and contribute to a better life for ourselves, our families and our society. Keep up to the good work!
