Preparations for Next Moonwalk Simulations Underway (and Underwater)
A digital rendering of the baseline configuration for Blue Origin’s free-flying commercial space station, Orbital Reef, which continues to be developed as part of a Space Act Agreement with NASA.Blue Origin A NASA-supported commercial space station, Blue Origin’s Orbital Reef, recently completed a human-in-the-loop testing milestone as the agency works toward developing commercial space stations in low Earth orbit.
The human-in-the-loop test scenarios utilized individual participants or small groups to perform day-in-the-life walkthroughs in life-sized mockups of major station components. Participants provided feedback while simulating microgravity operations, including cargo transfer, trash transfer, stowage, and worksite assessments.
“Human-in-the-loop and iterative testing are essential to inform key decisions and mitigate risks to crew health and safety,” said Angela Hart, program manager for NASA’s Commercial Low Earth Orbit Development Program at the agency’s Johnson Space Center in Houston. “NASA’s insight into our partner’s testing milestones enables the agency to gain insight into partner progress and share expertise, ultimately improving industry and NASA’s mission success.”

This ensures a commercial station can support human life, which is critical to advancing scientific research in a microgravity environment and maintaining a continuous human presence in low Earth orbit.
The test evaluated various aspects of Orbital Reef’s environment to provide information needed for the space station’s design. Assessment areas included the private crew quarters, dining area, lavatory, research laboratory, and berthing and docking hatches.
To facilitate the test, Blue Origin built stand-alone mockups of each floor in the internally developed habitable module. These mockups will be iteratively updated as the fidelity of components and subsystems matures, enabling future human-in-the-loop testing.
The research team’s observations will be used to provide design recommendations for worksite volumes, layouts, restraint and mobility aid layouts, usability and workload, and positioning of interfaces and equipment.
NASA supports the design and development of multiple commercial space stations, including Orbital Reef, through funded and unfunded agreements. The current design and development phase will soon be followed by the procurement of services from one or more companies, where NASA aims to be one of many customers for low Earth orbit stations.
NASA is committed to maintaining a continuous human presence in low Earth orbit as the agency transitions from the International Space Station to commercial space stations. For nearly 25 years, NASA has supported a continuous presence in low Earth orbit aboard the space station and will continue to build on the agency’s extensive human spaceflight experience to advance future scientific and exploration goals.

Exploring the unknown and preparing for humanity’s next giant leap really works up an appetite. Thankfully, employees at NASA’s Johnson Space Center in Houston can count on Tina Preyan to help them fuel up and stay focused.
Preyan is a food service specialist at Starport, a quality-of-life program that contributes to Johnson’s mission by providing employee services and activities that enhance work life and promote mental well-being and physical fitness. Part of the agency’s network of 12 NASA Exchanges — each located at a NASA center or facility — Starport offers everything from group fitness classes to retail shopping, with programs designed to engage, energize, and support the workforce.
Tina Preyan supports a NASA Exchange display at a Johnson Space Center event. Image courtesy of Tina Preyan Preyan oversees the on-site dining options at Johnson, from its cafés and food trucks to vending machines and mini markets. She helps set the budget for food services, creates monthly calendars of food offerings, schedules vendors and pop-up events, and ensures annual food safety inspections are conducted. She also works with teams across Johnson to order food and related supplies for NASA events.
“The best part of my job is working in customer service, meeting new NASA workers every day, and making everyone feel welcome and at home when coming to Johnson’s cafés,” she said.
Preyan has been a fixture at Johnson for the last 19 years. She previously worked at NASA’s Michoud Assembly Facility in New Orleans but transferred to Houston shortly after Hurricane Katrina hit the city in 2005. At Starport, she worked her way up from prep cook to lead cashier and then to lead assistant. She also served as the office’s administrative assistant before transitioning to her current role.
Tina Preyan poses for a photo with NASA astronauts Jessica Watkins and Victor Glover. Image courtesy of Tina Preyan Preyan has enjoyed meeting many NASA astronauts and Johnson team members and learning more about the work they do. The occasional celebrity sighting is another job perk.
Preyan is something of a celebrity herself. “So many employees know my name. I am proud of meeting so many people, and the love they give me every day just being here,” she said.
She was also proud to receive Starport’s Jackie Kingery Award in fall 2024. The award recognizes extraordinary customer service and exemplary dedication to the NASA Exchange mission at Johnson. “It felt amazing to receive this award and know that I am doing a great job in everyone’s eyes,” she said. “I value high integrity and am always willing to help others in the organization.”

Her son, Cameron, who is set to graduate from the University of Texas at San Antonio in May with a degree in Finance and Marketing.
In addition to her son’s graduation, Preyan looks forward to continuing her work in a positive environment and pursuing more growth opportunities.
“I’m going to stay busy and stay focused on ensuring proper procedures are being used by vendors,” she said. “And making sure all customers are happy and will continue to return to cafés.”

From left, Ramon Pedoto, Nathan Walkenhorst, and Tyrell Jemison review information at NASA’s Marshall Space Flight Center in Huntsville, Alabama. The three team members developed new automation tools at Marshall for flight controllers working with the International Space Station (Credit: NASA/Tyrell Jemison Two new automation tools developed at NASA’s Marshall Space Flight Center in Huntsville, Alabama, are geared toward improving operations for flight controllers working with the International Space Station from the Huntsville Operations Support Center.
The tools, called AutoDump and Permanently Missing Intervals Checker, will free the flight control team to focus on situational awareness, anomaly response, and real-time coordination.
The space station experiences routine loss-of-signal periods based on communication coverage as the space station orbits the Earth. When signal is lost, an onboard buffer records data that could not be downlinked during that period. Following acquisition of signal, flight controllers previously had to send a command to downlink, or “dump,” the stored data.
The AutoDump tool streamlines a repetitive data downlinking command from flight controllers by detecting a routine loss-of-signal, and then autonomously sending the command to downlink data stored in the onboard buffer when the signal is acquired again. Once the data has been downlinked, the tool will automatically make an entry in the console log to confirm the downlink took place.
“Reliably and quickly sending these dump commands is important to ensure that space station payload developers can operate from the most current data,” said Michael Zekoff, manager of Space Systems Operations at Marshall.
As a direct result of this tool, we have eliminated the need to manually perform routine data dump commands by as much as 40% for normal operations.

AutoDump was successfully deployed on Feb. 4 in support of the orbiting laboratory.
The other tool, known as the Permanently Missing Intervals Checker, is another automated process coming online that will improve team efficiency.
Permanently missing intervals are gaps in the data stream where data can be lost due to a variety of reasons, including network fluctuations. The missing intervals are generally short but are documented so the scientific community and other users have confirmation that the missing data is unable to be recovered.
“The process of checking for and documenting permanently missing intervals is challenging and incredibly time-consuming to make sure we capture all the payload impacts,” said Nathan Walkenhorst, a NASA contractor with Bailey Collaborative Solutions who serves as a flight controller specialist.
The checker will allow NASA to quickly gather and assess payload impacts, reduce disruptions to operations, and allow researchers to get better returns on their science investigations. It is expected to be deployed later this year.
In addition to Walkenhorst, Zekoff also credited Ramon Pedoto, a software architect, and Tyrell Jemison, a NASA contractor and data management coordinator with Teledyne Brown Engineering Inc, for their work in developing the automation tools. The development of the tools also requires coordination between flight control and software teams at Marshall, followed by extensive testing in both simulated and flight environments, including spacecraft operations, communications coverage, onboard anomalies, and other unexpected conditions.
“The team solicited broad review to ensure that the tool would integrate correctly with other station systems,” Zekoff said. “Automated tools are evaluated carefully to prevent unintended commanding or other consequences. Analysis of the tools included thorough characterization of the impacts, risk mitigation strategies, and approval by stakeholders across the International Space Station program.”
The Huntsville Operations Support Center provides payload, engineering, and mission operations support to the space station, the Commercial Crew Program, and Artemis missions, as well as science and technology demonstration missions. The Payload Operations Integration Center within the Huntsville Operations Support Center operates, plans, and coordinates the science experiments onboard the space station 365 days a year, 24 hours a day.
