Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s SPHEREx observatory undergoes integration and testing at BAE Systems in Boulder, Colorado, in April 2024. The space telescope will use a technique called spectroscopy across the entire sky, capturing the universe in more than 100 colors. BAE Systems The space telescope will detect over 100 colors from hundreds of millions of stars and galaxies. Here’s what astronomers will do with all that color.
NASA’s SPHEREx mission won’t be the first space telescope to observe hundreds of millions of stars and galaxies when it launches no later than April 2025, but it will be the first to observe them in 102 colors. Although these colors aren’t visible to the human eye because they’re in the infrared range, scientists will use them to learn about topics that range from the physics that governed the universe less than a second after its birth to the origins of water on planets like Earth.
“We are the first mission to look at the whole sky in so many colors,” said SPHEREx Principal Investigator Jamie Bock, who is based jointly at NASA’s Jet Propulsion Laboratory and Caltech, both in Southern California. “Whenever astronomers look at the sky in a new way, we can expect discoveries.”
Short for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer, SPHEREx will collect infrared light, which has wavelengths slightly longer than what the human eye can detect. The telescope will use a technique called spectroscopy to take the light from hundreds of millions of stars and galaxies and separate it into individual colors, the way a prism transforms sunlight into a rainbow. This color breakdown can reveal various properties of an object, including its composition and its distance from Earth.
NASA’s SPHEREx mission will use spectroscopy — the splitting of light into its component wavelengths — to study the universe. Watch this video to learn more about spectroscopy. NASA’s Goddard Space Flight Center Here are the three key science investigations SPHEREx will conduct with its colorful all-sky map.
Cosmic Origins
What human eyes perceive as colors are distinct wavelengths of light. The only difference between colors is the distance between the crests of the light wave. If a star or galaxy is moving, its light waves get stretched or compressed, changing the colors they appear to emit. (It’s the same with sound waves, which is why the pitch of an ambulance siren seems to go up as its approaches and lowers after it passes.) Astronomers can measure the degree to which light is stretched or compressed and use that to infer the distance to the object.
SPHEREx will apply this principle to map the position of hundreds of millions of galaxies in 3D. By doing so, scientists can study the physics of inflation, the event that caused the universe to expand by a trillion-trillion fold in less than a second after the big bang. This rapid expansion amplified small differences in the distribution of matter. Because these differences remain imprinted on the distribution of galaxies today, measuring how galaxies are distributed can tell scientists more about how inflation worked.
Galactic Origins
SPHEREx will also measure the collective glow created by all galaxies near and far — in other words, the total amount of light emitted by galaxies over cosmic history. Scientists have tried to estimate this total light output by observing individual galaxies and extrapolating to the trillions of galaxies in the universe. But these counts may leave out some faint or hidden light sources, such as galaxies too small or too distant for telescopes to easily detect.
With spectroscopy, SPHEREx can also show astronomers how the total light output has changed over time. For example, it may reveal that the universe’s earliest generations of galaxies produced more light than previously thought, either because they were more plentiful or bigger and brighter than current estimates suggest. Because light takes time to travel through space, we see distant objects as they were in the past. And, as light travels, the universe’s expansion stretches it, changing its wavelength and its color. Scientists can therefore use SPHEREx data to determine how far light has traveled and where in the universe’s history it was released.
Water’s Origins
SPHEREx will measure the abundance of frozen water, carbon dioxide, and other essential ingredients for life as we know it along more than 9 million unique directions across the Milky Way galaxy. This information will help scientists better understand how available these key molecules are to forming planets. Research indicates that most of the water in our galaxy is in the form of ice rather than gas, frozen to the surface of small dust grains. In dense clouds where stars form, these icy dust grains can become part of newly forming planets, with the potential to create oceans like the ones on Earth.
The mission’s colorful view will enable scientists to identify these materials, because chemical elements and molecules leave a unique signature in the colors they absorb and emit.
Big Picture
Many space telescopes, including NASA’s Hubble and James Webb, can provide high-resolution, in-depth spectroscopy of individual objects or small sections of space. Other space telescopes, like NASA’s retired Wide-field Infrared Survey Explorer (WISE), were designed to take images of the whole sky. SPHEREx combines these abilities to apply spectroscopy to the entire sky.
By combining observations from telescopes that target specific parts of the sky with SPHEREx’s big-picture view, scientists will get a more complete — and more colorful — perspective of the universe.
More About SPHEREx
SPHEREx is managed by JPL for NASA’s Astrophysics Division within the Science Mission Directorate in Washington. BAE Systems (formerly Ball Aerospace) built the telescope and the spacecraft bus. The science analysis of the SPHEREx data will be conducted by a team of scientists located at 10 institutions across the U.S. and in South Korea. Data will be processed and archived at IPAC at Caltech, which manages JPL for NASA. The mission principal investigator is based at Caltech with a joint JPL appointment. The SPHEREx dataset will be publicly available.

Senior Resource Analyst Julie Rivera Pérez ensures finances and assets are in place to enable missions’ engineering and science “magic” can happen. As a former intern, she also reaches out to current students to ensure a diverse and inclusive future workforce.
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.”
