Proba-3 is such an ambitious mission that it needs more than one single spacecraft to succeed. In order for Proba-3’s Coronagraph spacecraft observe the Sun’s faint surrounding atmosphere, the disk-bearing Occulter spacecraft must block out the fiery solar disk. This means Proba-3’s Occulter ends up facing the Sun continuously, making it a valuable platform for science in its own right.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Expedition 64 Flight Engineer Victor Glover of NASA sips on a water bag. The latest book marks our third effort to review available literature regarding the role of nutrition in astronaut health. In 2009, we reviewed the existing knowledge and history of human nutrition for spaceflight, with a key goal of identifying additional data that would be required before NASA could confidently reduce the risk of an inadequate food system or inadequate nutrition to as low as possible in support of human expeditions to the Moon or Mars. We used a nutrient-by-nutrient approach to address this effort, and we included a brief description of the space food systems during historical space programs.
In 2014, we published a second volume of the book, which was not so much a second edition, but rather a view of space nutrition from a different perspective. This volume updated research that had been published in the intervening 6 years and addressed space nutrition with a more physiological systems-based approach.
The current version is an expanded, updated version of that second book, providing both a systems approach overall, but also including details of nutrients and their roles within each system. As such, this book is divided into chapters based on physiological systems (e.g., bone, muscle, ocular); highlighted in each chapter are the nutrients associated with that particular system. We provide updated information on space food
systems and constraints of the same, and provide dietary intake data from International Space Station (ISS) astronauts.
We present data from ground-based analog studies, designed to mimic one or more conditions similar to those produced by spaceflight. Head-down tilt bed rest is a common analog of the general (and specifically musculoskeletal) disuse of spaceflight. Nutrition research from Antarctica relies on the associated confinement
and isolation, in addition to the lack of sunlight exposure during the winter months. Undersea habitats help expand our understanding of nutritional changes in a confined space with a hyperbaric atmosphere. We also review spaceflight research, including data from now “historical” flights on the Space Shuttle, data from the Russian space station Mir, and earlier space programs such as Apollo and Skylab. The ISS, now more than
20 years old, has provided (and continues to provide) a wealth of nutrition findings from extended-duration spaceflights of 4 to 12 months. We review findings from this platform as well, providing a comprehensive review of what is known regarding the role of human nutrition in keeping astronauts healthy.
With this latest book, we hope we have accurately captured the current state of the field of space food and nutrition, and that we have provided some guideposts for work that remains to be done to enable safe and successful human exploration beyond low-Earth orbit.

Dr. Nipa Phojanamongkolkij does not always do things the traditional way. As a systems engineer (SE) at Langley Research Center working closely with the Aeronautics Research Mission Directorate, Nipa pushes boundaries and draws connections where few others would think to look. When she envisioned a way to use ChatGPT to help SE teams working on the Advanced Air Mobility Mission, she presented her initial idea to her team wondering, “Is this crazy?” Her idea evolved into a successful prototype, which is now used for air traffic management in the Airspace Operations and Safety Program. She has also leveraged natural language programming and NASA’s database of lessons learned to create a bot for flagging potential risks and mitigations in real time. Nipa’s journey in becoming the digital transformer she is today involves her ability to combine engineering principles and business outcomes with creative, human-centered approaches.
Nipa received an MS and PhD in industrial and systems engineering from Arizona State University after moving to the United States from Bangkok, Thailand, where she received her BS degree in electronics engineering. She joined NASA 15 years ago after honing her data analysis and process improvement skills in the business sector at Pepsi Corporation. Her previous experience molded her focus on demonstrating benefit and return on investment. In addition to a business-oriented mindset, Nipa credits much of her success at NASA to her abilities as an active listener, which helps her understand customer needs and address paint points.
One cross-cutting challenge Nipa noticed within the agency’s approach to SE was the issue of silos, particularly in handling requirements and research data. Many engineers stored information in documents on individual computers or SharePoint folders, making it difficult to share data and draw connections across missions, directorates, and centers. As a systems engineer, Nipa and her team work to pull these disparate elements into a connected digital format using methodology called model-based systems engineering (MBSE). “You can think of it like a gigantic database where you have everything connected—a table of research papers, a table of requirements, and a table of concept of operations documents,” she says.
However, using and leveraging this system requires specialized knowledge of the MBSE discipline and modeling language. To centralize system concept, architecture, and requirement data while democratizing access to it, Nipa conceived a way to leverage ChatGPT as an intermediary between the user and database. In fiscal year 2023, she received funding for her idea as a Digital Transformation Prototype Test, “Requirement Discovery Using Embedded Knowledge Graph with ChatGPT.” Nipa and her team developed a web-based dashboard that translates user questions into database queries and turns the database responses back into readable answers for the user. Nipa and her team curated the research used to create the database, reducing the chances of AI hallucination and misinformation. Using ChatGPT as a translator, general users benefitted from the system without needing to know how to formulate graph database queries.
Requirement creation through this system was seven times faster than traditional processes and yielded results comparable to those created by subject matter experts. In some cases, the approach even resulted in more creative requirements than human-generated ones. Nipa’s prototype allowed SEs to more efficiently analyze connections between existing requirements, predict new connections, and generate new requirements, streamlining critical processes for her team. The approach could benefit SEs across NASA centers, directorates, and missions and holds exciting potential for other use cases, such as generating candidate requirements and analyzing project risk. According to NASA Digital Engineering Lead Terry Hill, “The future of engineering is understanding how to do it from a data-centric perspective. Enabling the use of new and evolving technologies like artificial intelligence, machine learning, and large language models will aid our engineers to accomplish greater things and augment our workforce.”
Nipa and her team were recognized for their innovative work, receiving a Systems Engineering Technical Excellence Award (SETEA) in 2024 under the “Advancement of SE” category. Nipa’s out-of-the-box thinking has also positioned her as a trailblazer amongst her peers. “Nipa was ahead of everyone in terms of understanding what Digital Transformation is,” says Ian Levitt, Concepts Team Manager at Langley Research Center and co-lead on the Requirement Discovery Prototype Test. “She is extremely smart as well as practical, which is a rare combination. She has wonderful insights and helps me see more clearly what I am trying to do.” As a leader in the Digital Transformation community, Nipa recognizes the importance of collaboration, noting that her transformative work would not have been successful without her team. Their trust is what makes her ideas possible, along with Digital Transformation’s willingness to take chances on innovative, cutting-edge ideas. “They’re at the forefront of technology, so they’re receptive to high-risk projects,” she says. “That’s why I enjoy working with the Digital Transformation team.”
In turn, Nipa is excited to continue building community and momentum around transformation initiatives. Her team’s work inspired one group at Johnson Space Center to replicate their requirement discovery approach, and she has received multiple inquiries for demos on their prototype. Seeing how her work inspires and impacts others at the agency is one way she measures success. Whether she is connecting data sources or people, Nipa continues to push toward a more unified NASA, exemplifying what it means to be a digital transformer.
