<\/a><\/figure>Name<\/strong>: Carissa M. Arillo What do you do and what is most interesting about your role here at Goddard?<\/strong><\/p>\n I developed pre-launch test procedures for the HARP-2 instrument for the Phytoplankton, Aerosol, Cloud and Ecosystem (PACE) Mission. HARP-2 is a wide angle imaging polarimeter designed to measure aerosol particles and clouds, as well as properties of land and water surfaces.<\/p>\n I also developed the flight operations routine and contingency procedures that governed the spacecraft after launch. It is interesting to think about how to design procedures that can sustain the observatory in space for the life of the mission so that the flight operations team that inherits the mission will have a seamless transition.<\/p>\n What is your educational background?<\/strong><\/p>\n In 2019, I got a Bachelor of Science in mechanical engineering from the University of Maryland, College Park. I am currently pursuing a master\u2019s in robotics there as well.<\/p>\n Why did you become an engineer?<\/strong><\/p>\n I like putting things together and understanding how they work. After starting my job at NASA Goddard, I became interested in coding and robotics.<\/p>\n How did you come to Goddard?<\/strong><\/p>\n After getting my undergraduate degree, I worked at General Electric Aviation doing operations management for manufacturing aircraft engines. When I heard about an opening at Goddard, I applied and got my current position.<\/p>\n What was involved in developing pre-launch test procedures for the HARP-2 instrument?<\/strong><\/p>\n I talked to the instrument manufacturer, which is a team from the University of Maryland, Baltimore County, and asked them what they wanted to confirm works every time we tested the instrument. We kept in constant communication while developing these test procedures to make sure we covered everything. The end product was code that was part of the comprehensive performance tests, the baseline tests throughout the prelaunch test campaign. Before, during, and after each prelaunch environmental test, we perform such a campaign. These prelaunch environmental tests include vibration, thermal (hot and cold), acoustic and radio frequency compatibility (making sure that different subsystems do not interfere with each other\u2019s).<\/p>\n What goes through your head in developing a flight operations procedure for an instrument?<\/strong><\/p>\n I think about a safe way of operating the instrument to accomplish the goals of the science team. I also think about not being able to constantly monitor the instrument. Every few hours, we can communicate with the instrument for about five to 10 minutes. We can, however, recover all the telemetry for the off-line time.<\/p>\n When we discover an anomaly, we look at all the history that we have and consult with our contingency procedures, our failure review board and potentially the instrument manufacturer. Together we try to figure out a recovery.<\/p>\n When developing a fight operations procedure, we must think of all possible scenarios. Our end product is a written book of procedures that lives with the mission and is updated as needed.<\/p>\n New cars come with an owner\u2019s manual. We create the same sort of manual for the new instrument.<\/p>\n As a Flight Operations Team member, what else do you do?<\/strong><\/p>\n The flight operations team runs the Mission Operations Center \u2014 the \u201cMOC\u201d \u2014 for PACE. That is where we command the spacecraft for the life of the mission. My specialty is the HARP-2 instrument, but I still do many supporting functions for the MOC. For example, I helped develop procedures to automate ground station contacts to PACE. These ground stations are positioned all over the world and enable us to talk with the spacecraft during those five to 10 minutes of communication. This automation includes the standard things we do every time we talk to the spacecraft whether or not someone is in the MOC.<\/p>\n How does it feel to be working on such an amazing mission so early in your career?<\/strong><\/p>\n It is awesome, I feel very lucky to be in my position. Everything is new to me. At times it is difficult to understand where the ship is going. I rely on my experienced team members to guide me and my robotics curriculum in school to equip me with skills.<\/p>\n I have learned a lot from both the flight operations team and the integration and test team. The flight operations team has years of experience building MOCs that serve the needs of each unique mission. The integration and test team also has a lot of experience developing observatory functional procedures. I wish to thank both teams for taking me under their wings and educating me on the fly to support the prelaunch, launch and post-launch campaigns. I am very grateful to everyone for giving me this unbelievable opportunity.<\/p>\n Who is your engineering hero?<\/strong><\/p>\n I don\u2019t have one hero in particular but I love biographical movies that tell stories about influential people\u2019s lives, such as the movie \u201cHidden Figures\u201d that details the great endeavors and accomplishments of three female African-American mathematicians at NASA.<\/p>\n What do you do for fun?<\/strong><\/p>\n I love to go to the beach and spend time with family and friends.<\/p>\n Who is your favorite author?<\/strong><\/p>\n I like Kristen Hannah\u2019s storytelling abilities.<\/p>\n What do you hope to be doing in five years?<\/strong><\/p>\n I hope to be working on another exciting mission at Goddard that will bring us never-before-seen science.<\/p>\n By\u00a0Elizabeth M.
