Esmarline De Leon Peralta: Looking to the Future at Ames Research Center

My name is Esmarline De León Peralta, a future physician-scientist, flight surgeon and astronaut. I am determined to be part of a group of experts and professionals that will develop key technologies for travel to and living on Mars. Furthermore, I would like to assist in developing the systems necessary to support astronauts’ and communities’ adaptability and survival in the environment on Mars. As an aspiring physician, I believe the advancements created as we continue to research what life could be like on Mars could also impact global health by providing healthcare accessibility and point-of-care technologies for both developing countries and under-developed areas.

I began to appreciate the importance of engagement, perseverance and empathy at a young age, largely due to the lack of resources and opportunities in my home country, the Dominican Republic. I grew up in a house made of tin and wood, where water and electricity were not always accessible, and even my home was not accessible during hurricane season. We moved to Puerto Rico when I was ten years old looking for better educational opportunities and a better life. My mother was denied career opportunities in the field of systems and computer engineering because her degree was obtained in a foreign country. Learning about challenges and inequalities was hard at a young age, but these experiences made me stronger and shaped me into an overachiever and passionate dreamer.

My journey to NASA has been one of the most inspiring challenges of my life. My immigration status affected my NASA goals but gave me the courage and inspiration to prepare and become not only a U.S. permanent resident, but an official citizen. I am a 2014 NASA Minority University Research and Education Program (MUREP) scholar, for which I give thanks to Ms. Elizabeth Cartier at ARC for her encouragement and constant support throughout these years.

My NASA interests, along with my desire to address problems in health and understand how chemicals impact the biomedical engineering field made me choose a career in chemical engineering at the University of Puerto Rico-Mayagüez. Since 2012, I have had experiences researching in biologically-inspired engineering labs at universities and hospitals such as Harvard University, Massachusetts General Hospital, Georgia Institute of Technology and Ohio State University. My interest in biomedical sciences and engineering encourages me to get a M.D.-Ph.D. as a physician-scientist in bioastronautics.

My passion for biomedical devices using 3-D printing was amplified after researching at Massachusetts General Hospital. When accepted at NASA, I felt that my dreams had come true and I was home where I belonged. I am currently a spring intern at NASA’s Ames Research Center in Silicon Valley. I am working in the Entry Systems and Vehicle Development Branch with Dr. Jing Li developing ultra-light weight batteries using 3-D printing technology and nanotechnology. This cutting-edge technology will enable new power and tools for space exploration and building human habitats in space.

During the summer of 2018, I will be interning at NASA’s Marshall Space Flight Center in Huntsville, Alabama. I will be working with a 3-D printer identical to one currently in space, the n-Scrypt 3-D printer, supporting 3-D multi-materials and process parameters for 3-D printing and helping in the fabrication of conductive inks to print small circuits under the mentorship and guidance of Mr. Curtis Hill.

Thank you, NASA, for being my dream, my present and my future. Here is where I belong! I cannot be more grateful. I have no words to express the happiness of my heart to represent minorities, Hispanics, women in STEM and the next generation of Mars and beyond planets’ explorers. God’s faithfulness last forever. Psalm 100:5

Xander Levinson: Seeing Beyond at NASA’s Ames Research Center

The James Webb Space Telescope (JWST) is one of NASA’s most highly-anticipated space-borne telescope projects. Its primary objective will be to directly image the oldest galaxies, planets, exoplanets, protostars, and brown dwarfs. The spacecraft, telescope, and its corresponding data receiving systems are still under development, with the complete observatory itself currently projected to launch in the spring of 2019.

I began my college education pursuing a linguistics degree at the University of Alaska in Fairbanks, but withdrew for personal and financial reasons after three years. I joined the workforce with a major international retailer until 2009’s recession, at which point I was laid off (then rehired, then laid off again). At this point, I knew retail was not the life for me. I decided to go all-in and chase my passion: SPACE! I started community college at both Golden West College (GWC) and Orange Coast College (OCC) in Orange County, California. It was at GWC that I was introduced to NASA’s educational outreach programs. I cannot emphasize enough the impact these opportunities have had on my life. Through a series of rigorous applications and elimination processes, I had the double honor of being selected to participate in two community college outreach programs at NASA/JPL: the Jet Propulsion Laboratory Undergraduate Scholars (JPLUS) program in the summer of 2015, followed by the National Community College Aerospace Scholars (NCAS) program in the spring of 2016.

It is absolutely because of my involvement in these programs that I had the confidence to push myself in school, and to apply for this internship at NASA Ames Research Center. I graduated from GWC with an A.A. in Chemistry and an A.S. in Mathematics; and from OCC with an A.S. in Physics and an A.S. in Astronomy – the first such degree ever conferred by that institution. As I pursue a bachelor’s in astrophysics and a minor in Earth and Planetary Sciences nearby at UC Santa Cruz (Go Banana Slugs!), it has become more and more apparent that my dream career will have me involved with exoplanet discovery and classification programs.

Of course, being a major Trekkie, my absolute dream would be to physically travel to these worlds to analyze them personally. However, since that technology is not currently available, I am happy to work with high-quality spectroscopy data in the meantime. Everyone loves pretty pictures, right? So, this opportunity at Ames was one I could not allow to slip through my hands. Thankfully, I was selected and am excited and proud to work with Tom Greene and his team (including my partner intern Stephanie Striegel from San Jose State University) on the James Webb Space Telescope project.

My goals as an intern on this project are to implement and refine the pipeline for incoming data transmissions (once the telescope is launched), facilitate data reduction of received downlink information, and to provide automated statistical analysis of data. In short, my job is to automate the systematic, efficient identification and classification of substellar objects – with much greater clarity and accuracy than ever before. In order to accomplish this seemingly daunting task, my teammate and I run Python scripts to analyze and sort spectroscopic data, which we will eventually use in describing (in great detail) the constructions and atmospheres of extrasolar bodies. Currently, we are calibrating our codes using sample data from a recent batch of tests run on the instrumentation itself. We plan to further refine it using other data reduction codes provided by the Space Telescope Science Institute (STScI) in the near future.

I think the most exciting part of this project is that it is very likely that our work will be how we may someday identify “Earth 2.0” out there! This project is both humbling and inspiring. The work comes with a realization of how small and young we truly are, but it also amazes me how much information we are able to glean from a small beam of light from such distant places. Years from now, when I look at the images that JWST will present to us, I will know that I had a part in making it happen. For me, there is nothing more rewarding than the knowledge that my efforts here at NASA Ames will contribute immeasurably to humanity’s quest to understand the universe, as well as our place in it.
