Supporting the International Space Station is an around-the-clock responsibility for NASA and its international partners. This means there is always a team of flight operations and payload personnel working with the orbiting laboratory’s crew – including overnight, on weekends, and during the holidays.
At Johnson Space Center’s Mission Control Center (MCC) in Houston, flight directors organize fun activities to help these teams build camaraderie and celebrate holidays while they work, no matter the hour.
“Working in mission control is a very rewarding job, but it also demands a lot from flight controllers and leads to time away from family,” said Fiona Antkowiak, a flight director in the MCC. “We really want to make the holiday shifts in MCC extra special.”
Fiona Antkowiak (front right) and her Orbit 3 shift team members show off their holiday cookie creations in the Mission Control Center (MCC) at NASA’s Johnson Space Center in Houston. Image courtesy of Fiona Antkowiak Antkowiak recalled working Christmas 2018 as a space station flight controller. That year, teams participated in a friendly cookie-decorating competition, with the three different MCC shifts going head-to-head. When flight directors started brainstorming festive ideas for the 2024 holiday season, Antkowiak suggested reviving the contest and asked the Expedition 72 crew if they would be willing to judge the entries. “They agreed, and also told us they would decorate some cookies for us to judge, too!”
Astronauts aboard the International Space Station often decorate cookies as part of their holiday celebrations and have become adept at manipulating icing in zero gravity. NASA astronaut Nick Hague shared on social media, “It opened up a whole new dimension, quite literally, with layer upon layer of icing.”
The Expedition 72 crew decorates cookies aboard the International Space Station (left), and their finished products. NASA Teams in the MCC in Houston and NASA’s Marshall Space Flight Center Payload Operations Integration Center in Huntsville, Alabama, were joined by international partners ESA (European Space Agency) and JAXA (Japan Aerospace Exploration Agency) from their respective control centers. The decorating began late on Christmas Eve and concluded on Christmas Day, ensuring space station crew members could participate in the fun on their days off.
The 36 entries drew inspiration from traditional holiday imagery, human spaceflight, sports teams, and comic books. Each crew member selected their personal favorite cookie, in addition to choosing an overall winner. Payload Operations Director Jaclyn Poteraj created the winning cookie, depicting an astronaut riding on a reindeer made of cargo transfer bags, which are used to transport cargo to and store it aboard the International Space Station.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s Stennis Space Center near Bay St. Louis, Mississippi, is helping the Artemis Generation learn how to power space dreams with an interactive exhibit at INFINITY Science Center.
The engine test simulator exhibit at the official visitor center of NASA Stennis provides the chance to experience the thrill of being a NASA test engineer by guiding an RS-25 engine through a simulated hot fire test.
“It is an exhilarating opportunity to feel what it is like to be a NASA engineer, responsible for making sure the engine is safely tested for launch,” said Chris Barnett-Woods, a NASA engineer that helped develop the software for the exhibit.
Sitting at a console mirroring the actual NASA Stennis Test Control Center, users are immersed in the complex process of engine testing. The exhibit uses cutting-edge software and visual displays to teach participants how to manage liquid oxygen and liquid hydrogen propellants, and other essential elements during a hot fire.
A pair of young visitors to INFINITY Science Center carry out the steps of a simulated RS-25 engine hot fire on Dec. 19. The updated engine test simulator exhibit provided by NASA’s Stennis Space Center takes users through the hot fire process just as real engineers do at NASA Stennis.NASA/Danny Nowlin INFINITY Science Center, the official visitor center for NASA’s Stennis Space Center, has unveiled a new interactive simulator exhibit that allows visitors to become the test conductor for an RS-25 engine hot fire. NASA/Danny Nowlin Users follow step-by-step instructions that include pressing buttons, managing propellant tanks, and even closing the flare stack, just as real engineers do at NASA Stennis. Once the test is complete, they are congratulated for successfully conducting their own rocket engine hot fire.
The interactive exhibit is not just about pushing buttons. It is packed with interesting facts about the RS-25 engine, which helps power NASA’s Artemis missions as the agency explores secrets of the universe for the benefit of all. Visitors also can view real hot fires conducted at NASA Stennis from multiple angles, deepening their understanding of rocket propulsion testing and NASA’s journey back to the Moon and beyond.
NASA is currently preparing for the Artemis II mission, the first crewed flight test of the agency’s powerful SLS (Space Launch System) rocket and the Orion spacecraft around the Moon.
The first four Artemis missions are using modified space shuttle main engines tested at NASA Stennis. The center also achieved a testing milestone last April for engines to power future Artemis missions. For each Artemis mission, four RS-25 engines, along with a pair of solid rocket boosters, power NASA’s SLS rocket, producing more than 8.8 million pounds of total combined thrust at liftoff.
The revitalized exhibit, previously used when the visitor center was located onsite, represents a collaborative effort. It started as an intern project in the summer of 2023 before evolving into a full-scale experience. Engineers built on the initial concept, integrating carpentry, audio, and video to create the seamless experience to educate and inspire.
The best part might be that visitors to INFINITY Science Center can repeat the simulation as many times as they like, gaining confidence and learning more with each attempt.
“This exhibit was a favorite in the past, and with its new upgrades, the engine test simulator is poised to capture the imaginations of the Artemis Generation at INFINITY Science Center,” said NASA Public Affairs Specialist Samone Wilson. “This is one exhibit you will not want to miss.” INFINITY Science Center is located at 1 Discovery Circle, Pearlington, Mississippi.

Imagine designing technology that can survive on the Moon for up to a decade, providing a continuous energy supply. NASA selected three companies to develop such systems, aimed at providing a power source at the Moon’s South Pole for Artemis missions.
Three companies were awarded contracts in 2022 with plans to test their self-sustaining solar arrays at the Johnson Space Center’s Space Environment Simulation Laboratory (SESL) in Houston, specifically in Chamber A in building 32. The prototypes tested to date have undergone rigorous evaluations to ensure the technology can withstand the harsh lunar environment and deploy the solar array effectively on the lunar surface.

NASA/James Blair In the summer of 2024, both Honeybee Robotics, a Blue Origin company from Altadena, California and Astrobotic Technology from Pittsburgh, Pennsylvania put their solar array concepts to the test in Chamber A.
Each company has engineered a unique solution to design the arrays to withstand the harsh lunar environment and extreme temperature swings. The data collected in the SESL will support refinement of requirements and the designs for future technological advancements with the goal to deploy at least one of the systems near the Moon’s South Pole.
The contracts for this initiative are part of NASA’s VSAT (Vertical Solar Array Technology) project, aiming to support the agency’s long-term lunar surface operations. VSAT is under the Space Technology Mission Directorate Game Changing Development program and led by the Langley Research Center in Hampton, Virginia, in collaboration with Glenn Research Center in Cleveland.
“We foresee the Moon as a hub for manufacturing satellites and hardware, leveraging the energy required to launch from the lunar surface,” said Jim Burgess, VSAT lead systems engineer. “This vision could revolutionize space exploration and industry.”
Built in 1965, the SESL initially supported the Gemini and Apollo programs but was adapted to conduct testing for other missions like the Space Shuttle Program and Mars rovers, as well as validate the design of the James Webb Space Telescope. Today, it continues to evolve to support future Artemis exploration.
Johnson’s Front Door initiative aims to solve the challenges of space exploration by opening opportunities to the public and bringing together bold and innovative ideas to explore new destinations.
“The SESL is just one of the hundreds of unique capabilities that we have here at Johnson,” said Molly Bannon, Johnson’s Innovation and Strategy specialist. “The Front Door provides a clear understanding of all our capabilities and services, the ways in which our partners can access them, and how to contact us. We know that we can go further together with all our partners across the entire space ecosystem if we bring everyone together as the hub of human spaceflight.”
Chamber A remains as one of the largest thermal vacuum chambers of its kind, with the unique capability to provide extreme deep space temperature conditions down to as low as 20 Kelvin. This allows engineers to gather essential data on how technologies react to the Moon’s severe conditions, particularly during the frigid lunar night where the systems may need to survive for 96 hours in darkness.
“Testing these prototypes will help ensure more safe and reliable space mission technologies,” said Chuck Taylor, VSAT project manager. “The goal is to create a self-sustaining system that can support lunar exploration and beyond, making our presence on the Moon not just feasible but sustainable.”
The power generation systems must be self-aware to manage outages and ensure survival on the lunar surface. These systems will need to communicate with habitats and rovers and provide continuous power and recharging as needed. They must also deploy on a curved surface, extend 32 feet high to reach sunlight, and retract for possible relocation.
“Generating power on the Moon involves numerous lessons and constant learning,” said Taylor. “While this might seem like a technical challenge, it’s an exciting frontier that combines known technologies with innovative solutions to navigate lunar conditions and build a dynamic and robust energy network on the Moon.”
Watch the video below to explore the capabilities and scientific work enabled by the thermal testing conducted in Johnson’s Chamber A facility.
