The next CSUG event will take place November 6 – 7 at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
Throughout the CSUG, representatives from NASA’s Space Communications and Navigation program and CSP’s industry partners will share updates on commercial SATCOM capability developments and the commercial service demonstrations taking place under CSP.
NASA attendees must be badged and have physical access to Goddard Space Flight Center to attend in-person. There will be limited in-person seating, so RSVPs are required. Meeting invitations and an agenda will be provided to CSP’s active CSUG roster as details are finalized.
Please contact mission support lead engineer Aaron Smith, aaron.smith@nasa.gov, or CSUG team member Michele Vlach, michele.m.vlach@nasa.gov , for inquires and requests to be added to the CSUG distribution list.
Funded Space Act Agreement Partners
In 2022, CSP awarded six funded Space Act Agreements to members of industry to develop and demonstrate space-based relay services that can meet NASA mission needs.

Viasat’s Real-Time Space Relay service, enabled by the anticipated ViaSat-3 network, is designed to offer a persistent on-demand capability for low-Earth orbit operators.
Non-Reimbursable Space Act Agreement Partners
CSP is also formulating non-reimbursable Space Act Agreements with members of industry to grow the domestic SATCOM market, potentially expanding future space-relay offerings for NASA missions.
Kepler Communications US Inc.
Kepler Communications US Inc. plans to deliver data at lightspeed with a Space Development Agency-compatible optical data relay network, connecting space and Earth communications with low latency, high throughput, and enhanced security. The Kepler Network plans to provide complete coverage of all low-Earth orbit above 400 km altitude.

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.
