A mentor of research scientist Meloë Kacenelenbogen once shared a sentiment from French author André Gide: “You cannot discover new oceans unless you have the courage to lose sight of the shore.” Kacenelenbogen pushes beyond her comfort zone to explore the unknown.
Name: Meloë S. Kacenelenbogen
Formal Job Classification: Research scientist
Organization: Climate and Radiation Laboratory, Science Directorate (Code 613)
Dr. Meloë S. Kacenelenbogen is a research scientist at NASA’s Goddard Space Flight Center in Greenbelt, Md. She studies the impact of aerosols on air quality and the Earth’s climate.Photo courtesy of Meloë Kacenelenbogen What do you do and what is most interesting about your role here at Goddard?
I study the impact of aerosols — suspended particles from, for example, wildfire smoke, desert dust, urban pollution, and volcanic eruptions — on air quality and the Earth’s climate. I use space, air, and ground-based observations, as well as models.
Why did you become a scientist? What is your educational background?
I never made a deliberate choice to become a scientist. I started with very little confidence as a child and then built up my confidence by achieving things I thought I could not do. I chose the hardest fields to work on along the way. Science looked hard and so did fluid mechanics, remote sensing, and atmospheric physics. I have failed many times, but I always learn something and move on. I do get scared and maybe even paralyzed for a day or two, but I never let fear or failure immobilize me for long.
I was born in Maryland, but my family moved to France when I was young, so I am fluent in French. I have a bachelor’s and master’s degree in mechanical engineering, and physical methods in remote sensing from the Université Pierre et Marie Curie (Paris VI, Jussieu). In 2008, I got a Ph.D. in atmospheric physics for applying satellite remote sensing to air quality at the Université des Sciences et Technologies de Lille (USTL), France.
What are some of your career highlights?
After my Ph.D., I worked for the Atmospheric Lidar Group at the University of Maryland, Baltimore County (UMBC), on spaceborne and ground-based lidars. In 2009, I got a NASA Post-doctoral Program (NPP) fellowship at the agency’s Ames Research Center in California’s Silicon Valley, where I worked for 13 years on space-based, aircraft-based, and ground-based atmospheric aerosol vertical distribution and aerosol typing.
In 2022, I came to work at the Climate and Radiation Lab at Goddard.
What is most interesting about aerosols?
Aerosols are very topical because they have a huge impact on the air we breathe and our Earth’s climate. The smaller the aerosol, the deeper it can get into our lungs. Among other sources, aerosols can come from cars, factories, or wildfires. We all know that wildfires are becoming bigger and more frequent. They are expected to happen even more frequently in the future due to climate change. Both when I was living in California and here in Maryland, I have experienced first-hand choking from the wildfire smoke. I will always remember how apocalyptic it felt back in the summer of 2020 in California when wildfire smoke was paired with COVID confinement, and the sky turned Mars-like orange.
Please tell us about your involvement with the Atmosphere Observing System (AOS)?
I am incredibly lucky to be able to contribute to the next generation of NASA’s satellites. I am working on AOS, which will observe aerosols, clouds, convention, and precipitation in the Earth’s atmosphere. I am part of the team that is helping design several instruments and algorithms.
My role is to connect this spaceborne observing system to all our other space, ground, and air-based measurements at the time of launch. We are making a mesh of observations to address the science questions, run the algorithms, and validate the spaceborne measurements. I am constantly pushed to expand my horizon and my own knowledge.
Why do you enjoy always challenging yourself intellectually?
I started that way. I had no confidence, so I felt that the only way I could build my confidence was to try doing things that scared me. I may sometimes be a little scared, but I am never bored.
What did you learn from your mentors?
A few years ago, a mentor shared a quote from André Gide with me that encapsulates what we are talking about: “You cannot discover new oceans unless you have the courage to lose sight of the shore.” In other words, it is OK, maybe preferable, to be out of my comfort zone to explore the unknown as scary as it may be.
Along the way, it has been extremely important for me to deliberately choose mentors. To me, a good mentor has earned the respect of all who have worked with them, is uplifting, reassuring, and gives me the invaluable guidance and support that I need. I deliberately try to surround myself with the right people. I have been very, very fortunate to find incredible people to encourage me.
As a mentor, what do you advise?
I tell them to deliberately choose their mentors. I also tell them that it is OK to be uncomfortable. Being uncomfortable is the nature of our field. To do great things, we often need to be uncomfortable.
Why do you enjoy working on a team?
I love working on teams, I love to feed off the positive energy of a team whether I lead it or am part of it. In my field, teamwork with a positive energy is incredibly satisfying. Everybody feeds off everybody’s energy, we go further, are stronger, and achieve more. This may not happen often, but when it does it makes it all worth it.
What are the happiest moments in your career?
I am always happiest when the team publishes a paper and all our efforts, are encapsulated in that one well-wrapped and satisfying peer-reviewed paper that is then accessible to everyone online. Every paper we publish feels, to me, the same as a Ph.D. in terms of the work, pain, energy, and then, finally, satisfaction involved.
What do you hope to achieve in your career?
I want to have been a major contributor to the mission by the time the AOS satellites launch.
What do you do for fun?
I do mixed martial arts. I love the ocean, diving, and sailing. I also love going to art galleries, especially to see impressionist paintings to reconnect with my Parisian past.
Meloë Kacenelenbogen once shared a sentiment from French author André Gide: “You cannot discover new oceans unless you have the courage to lose sight of the shore.”Photo courtesy of Meloë Kacenelenbogen Who is your favorite author?
I love Zweig, Kafka, Dostoyevsky, Saint-Exupéry, and Kessel. The latter two wrote a lot about aviators in the early 1900s back in the days when it was new and very dangerous. Those pilots, like Mermoz, were my heroes growing up.
Who would you like to thank?
I would like to thank my family for being my rock.
What are your guiding principles?
To paraphrase Dostoevsky, everyone is responsible to all men for all men and for everything. I have a strong sense of purpose, pride, justice, and honor. This is how I try to live my life for better or for worse.

Where do asteroids get all those craters? Countless small circular craters, plus almost always a few that look like massive killers. Even more confusing is that these craters are at a perfect 90º angle, as if an electric arc had run across the surface.
According to ThunderboltsProject, the Electric Universe (EU) model, the scars observed on asteroids are caused by electric arcs which cut surface depressions, scoop out material, accelerate it into space, then leave behind clean-cut geological relief.
This theory is supported by Electric Discharge Machining (EDM), a process we use every day to shape materials with electric arcs, producing similar clean-cut effects.
This brings us to the following hypothesis: Could it be that, instead of craters on asteroids being formed solely by natural space phenomena, that all these craters at a perfect 90º angle with clean-cut geological relief are the result of asteroid mining originated by alien races who use advanced electric arc/laser technology by extracting raw minerals they urgently need for use on their planet or for in-space manufacturing?
Asteroids vary greatly in composition, ranging from those rich in volatile substances to those composed of metals like gold, silver, platinum, cobalt, and palladium, alongside more common elements such as iron and nickel. This makes them potential treasure troves of valuable resources.
For us as Earthlings, asteroid mining is a technology in its earliest stages and requires significant advances in robotic technology before asteroid mining becomes a reality, however, if more advanced civilizations exist elsewhere in the universe, it's quite plausible that some of them have already turned to asteroid mining long ago.
Could their efforts be leaving behind the very craters on asteroids we observe today?

Name: Julie Rivera Pérez
Formal Job Classification: Senior Resources Analyst
Organization: Systems Review Office/Resource Management Office, Office of the Chief Financial Officer (Code 159.2)
Julie Rivera Pérez is a senior resources analyst at NASA’s Goddard Space Flight Center in Greenbelt, Md. Photo courtesy of Julie Rivera Pérez What do you do and what is most interesting about your role here at Goddard?
I work in Goddard’s Systems Review Office (SRO), which plays a critical role in NASA’s mission gate reviews, also known as system review boards (SRBs). As the lead senior resources analyst, I provide financial expertise relating to budget planning and funds execution in support of all life-cycle reviews for Goddard missions. These reviews occur during key milestones in the progression of a mission through the various stages until launch. A mission cannot proceed with its work unless it passes the gate reviews, like the preliminary design review (PDR), critical design review (PDR), system integration review (SIR), operational readiness review (ORR), among others. It is great to support these reviews and make sure that key panel members like engineering, science, cost/schedule, and programmatic subject matter experts are planned for and funded to hold these SRB reviews. It is exciting to be able to contribute to Goddard missions!
What is your educational background?
In 2010, I graduated from the University of Puerto Rico, Río Piedras Campus, with a bachelor’s degree in business administration. My major was in human resources, and my minor was in marketing.
Why did you come to Goddard?
I first came to Goddard in 2008, as a summer intern. I will never forget the team of recruiters that visited my university and shared Goddard’s opportunities for business majors. I dreamed to contribute to the NASA mission! I took a chance and signed up to be interviewed. Three months later, I was offered an internship, and here I am, nearly 15 years later and thriving!
Where have you worked at Goddard? What was a pivotal moment for you?
In 2009, I had the opportunity to intern with the Office of Human Capital Management, the Office of Diversity and Equal Opportunity, and the Office of Education.
After graduating in 2010, I joined Goddard as a procurement analyst in the Small Business Office. In 2013, I became the Contracting Officer for the Geostationary Operational Environmental Satellite (GOES) system.
In 2015, I was selected as a participant in the NASA FIRST Program, a very prestigious NASA leadership program, which was pivotal for me. I learned about different roles at NASA including the important roles of business professionals. This inspired me to transition into the world of resources and finance!
In 2017, I became a senior resources analyst for the Joint Polar Satellite System (JPSS). My procurement background helped me understand the underlying contractual mechanics in the world of resources. I was very excited to continue to grow in my NASA career! In 2018, I served as a contract resources analyst of the Ground Systems and Missions Operations 2 contract for the Space Science Mission Operations Division. Presently, I serve as the lead senior resources analyst for the Systems Review Office within the Safety and Mission Assurance Business Branch of the Office of the Chief Financial Officer (OCFO).
It has been an amazing journey! I have had the opportunity to work in multiple flagship missions, mission operations, interagency collaborations, procurement, finance, and resources. I am excited for what the future will bring in my NASA career!
What are your responsibilities in your current role?
My key responsibility is serving as the financial liaison between the Systems Review Office (SRO) and program or project offices. I collaborate with program managers, deputy program managers for resources, and financial managers from other NASA centers to ensure the proper coordination of system review boards’ funding requirements. This includes preparing program, planning, budget, and execution (PPBE) inputs, labor projections, continuing resolution funding requirements, and phasing plans for all SRB missions.
As the SRO lead senior resources analyst, I also oversee the daily functions and activities of the SRO staff members, providing them with appropriate guidance, direction, knowledge sharing, and mentorship.
What are you most thankful about in your career?
I have had many opportunities from the moment I started working at Goddard as an intern. I have always been encouraged to continue growing as a professional through several significant work opportunities. One of them being the NASA FIRST leadership program for the 2015 cohort. It was a joy when I was accepted into this life-changing and unique opportunity! Throughout my career at Goddard, I have learned about many different aspects and the importance of being a business professional to help achieve the NASA mission.
Who is your mentor and what is their advice?
I have had several amazing mentors throughout my career at Goddard. Dan Krieger was key in my recruitment and has always supported me through my journey. Veronica Hill has continuously provided her guidance and wisdom. Janine Dolinka welcomed me to Goddard as my first mentor and further inspired me grow at NASA. Jennifer Perez took me under her wing and taught me the importance and roles of the Small Business Office. Currently, I am under the mentorship of Rich Ryan (deputy program director for business, Mars Sample Return) and Kevin Miller (chief of Resources Management Office). All in all, my mentors have always reminded me to always be my authentic self. It sounds so simple, yet it is such powerful advice. I want to thank each and every one of them for fueling the desire to make a difference for the NASA mission and to continue bringing my talents to the workforce!
What is important to you about your role on the Hispanic Advisory Committee for Employees (HACE)?
A very fulfilling part of the work I do at NASA Goddard is my voluntary service as the co-chair for the Hispanic Advisory Committee for Employees (HACE) resource group. I am in a unique position to provide advice, guidance, and recommendations to center management, the Office of STEM Engagement, and the Office of Diversity and Equal Opportunity on initiatives regarding recruitment, outreach, retention, cultural awareness, and professional development of minorities and Hispanics at Goddard. I also serve as the recruitment and outreach co-lead for the committee. As co-chair, I am a voice representing the interests of the GSFC Hispanic community.
I also develop key initiatives in student recruitment and outreach to build a pipeline of Hispanic interns for NASA. Every summer, I coordinate intern presentations to center management, as well as provide training to the Hispanic interns on how to write a federal résumé and apply for a federal job within NASA.
It is my wish to pay it forward. I once was an intern. I want to encourage others to join the NASA community and make a positive impact with diversity, equity, inclusion, and accessibility. Así Se HACE!
In 2021, you were a panel speaker at the Women of Color conference. What did you talk about?
It was such an honor to be invited as a panel speaker with a financial professional background for a STEM event. I served as a bridge between STEM and the business world and how both come together to make the magic happen. I have a deep understanding of how the business world and the engineering and science come together to bring missions to life. While I may not have a STEM degree, I am a STEM advocate. This event was an opportunity to tell my story as a Hispanic woman in resources and finance working at NASA. As a business professional, it is important that the money and the assets are in place so all the engineering and science can happen. It was equally important to highlight the value of embracing yourself and what you bring you the table because that is where your strength lies and how you can make a difference.
What do you do for fun?
I have a passion for singing! Since my early teens, I studied music and singing at the Music Conservatory of Puerto Rico. In college, I was accepted into the very competitive University of Puerto Rico classical choir. I continued to pursue my love for music through the Goddard Music and Drama Club (MAD). I even starred in two musicals produced by MAD!
I love spending time with my husband and two children, as well as watching movies with family and friends, spending time at the beach, reading, walking, listening to true crime podcasts, and watching the occasional Spanish telenovela.
What is your favorite life quote?
This Gandhi quote speaks to the power of perseverance and means a lot to me: “Strength does not come from physical capacity. It comes from an indomitable will.”
