Preparations for Next Moonwalk Simulations Underway (and Underwater)
A crane lowers the steel reflector framework for Deep Space Station 23 into position Dec. 18 on a 65-foot-high (20-meter) platform above the antenna’s pedestal that will steer the reflector. Panels will be affixed to the structure create a curved surface to collect radio frequency signals.NASA/JPL-Caltech After the steel framework of the Deep Space Station 23 reflector dish was lowered into place on Dec. 18, a crew installed the quadripod, a four-legged support structure that will direct radio frequency signals from deep space that bounce off the main reflector into the antenna’s receiver.NASA/JPL-Caltech Deep Space Station 23’s 133-ton reflector dish was recently installed, marking a key step in strengthening NASA’s Deep Space Network.
NASA’s Deep Space Network, an array of giant radio antennas, allows agency missions to track, send commands to, and receive scientific data from spacecraft venturing to the Moon and beyond. NASA is adding a new antenna, bringing the total to 15, to support increased demand for the world’s largest and most sensitive radio frequency telecommunication system.
Installation of the latest antenna took place on Dec. 18, when teams at NASA’s Goldstone Deep Space Communications Complex near Barstow, California, installed the metal reflector framework for Deep Space Station 23, a multifrequency beam-waveguide antenna. When operational in 2026, Deep Space Station 23 will receive transmissions from missions such as Perseverance, Psyche, Europa Clipper, Voyager 1, and a growing fleet of future human and robotic spacecraft in deep space.
“This addition to the Deep Space Network represents a crucial communication upgrade for the agency,” said Kevin Coggins, deputy associate administrator of NASA’s SCaN (Space Communications and Navigation) program. “The communications infrastructure has been in continuous operation since its creation in 1963, and with this upgrade we are ensuring NASA is ready to support the growing number of missions exploring the Moon, Mars, and beyond.”
This time-lapse video shows the entire day of construction activities for the Deep Space Station 23 antenna at the NASA Deep Space Network’s Goldstone Space Communications Complex near Barstow, California, on Dec. 18. NASA/JPL-Caltech Construction of the new antenna has been under way for more than four years, and during the installation, teams used a crawler crane to lower the 133-ton metal skeleton of the 112-foot-wide (34-meter-wide) parabolic reflector before it was bolted to a 65-foot-high (20-meter-high) alidade, a platform above the antenna’s pedestal that will steer the reflector during operations.
“One of the biggest challenges facing us during the lift was to ensure that 40 bolt-holes were perfectly aligned between the structure and alidade,” said Germaine Aziz, systems engineer, Deep Space Network Aperture Enhancement Program of NASA’s Jet Propulsion Laboratory in Southern California. “This required a meticulous emphasis on alignment prior to the lift to guarantee everything went smoothly on the day.”
Following the main lift, engineers carried out a lighter lift to place a quadripod, a four-legged support structure weighing 16 1/2 tons, onto the center of the upward-facing reflector. The quadripod features a curved subreflector that will direct radio frequency signals from deep space that bounce off the main reflector into the antenna’s pedestal, where the antenna’s receivers are housed.
In the early morning of Dec. 18, a crane looms over the 112-foot-wide (34-meter-wide) steel framework for Deep Space Station 23 reflector dish, which will soon be lowered into position on the antenna’s base structure.NASA/JPL-Caltech Engineers will now work to fit panels onto the steel skeleton to create a curved surface to reflect radio frequency signals. Once complete, Deep Space Station 23 will be the fifth of six new beam-waveguide antennas to join the network, following Deep Space Station 53, which was added at the Deep Space Network’s Madrid complex in 2022.
“With the Deep Space Network, we are able to explore the Martian landscape with our rovers, see the James Webb Space Telescope’s stunning cosmic observations, and so much more,” said Laurie Leshin, director of JPL. “The network enables over 40 deep space missions, including the farthest human-made objects in the universe, Voyager 1 and 2. With upgrades like these, the network will continue to support humanity’s exploration of our solar system and beyond, enabling groundbreaking science and discovery far into the future.”
NASA’s Deep Space Network is managed by JPL, with the oversight of NASA’s SCaN Program. More than 100 NASA and non-NASA missions rely on the Deep Space Network and Near Space Network, including supporting astronauts aboard the International Space Station and future Artemis missions, monitoring Earth’s weather and the effects of climate change, supporting lunar exploration, and uncovering the solar system and beyond.

A method for evaluating thermophysical properties of metal alloys
Simulation of the solidification of metal alloys, a key step in certain industrial processes, requires reliable data on their thermophysical properties such as surface tension and viscosity. Researchers propose comparing predictive models with experimental outcomes as a method to assess these data.
Scientists use data on surface tension and viscosity of titanium-based alloys in industrial processes such as casting and crystal growth. Non-Equilibrium Solidification, Modelling for Microstructure Engineering of Industrial Alloys, an ESA (European Space Agency) investigation, examined the microstructure and growth of these alloys using the station’s Electromagnetic Levitator. This facility eliminates the need for containers, which can interfere with experiment results.
European Space Agency (ESA) astronaut Alexander Gerst is shown in the Columbus module of the International Space Station during the installation of the Electromagnetic Levitator.ESA/Alexander Gerst Overview of techniques for measuring thermal diffusion
Researchers present techniques for measuring thermal diffusion of molecules in a mixture. Thermal diffusion is measured using the Soret coefficient – the ratio of movement caused by temperature differences to overall movement within the system. This has applications in mineralogy and geophysics such as predicting the location of natural resources beneath Earth’s surface.
A series of ESA investigations studied diffusion, or how heat and particles move through liquids, in microgravity. Selectable Optical Diagnostics Instrument-Influence of VIbrations on DIffusion of Liquids examined how vibrations affect diffusion in mixtures with two components and SODI-DCMIX measured more-complex diffusion in mixtures of three or more components. Understanding and predicting the effects of thermal diffusion has applications in various industries such as modeling of underground oil reservoirs.
NASA astronaut Kate Rubins works on Selectable Optical Diagnostics Instrument Experiment Diffusion Coefficient Mixture-3 (SODI) DCMix-3 installation inside the station’s Microgravity Science Glovebox.JAXA (Japan Aerospace Exploration Agency)/Takuya Onishi Research validates ferrofluid technology
Researchers validated the concept of using ferrofluid technology to operate a thermal control switch in a spacecraft. This outcome could support development of more reliable and long-lasting spacecraft thermal management systems, increasing mission lifespan and improving crew safety.
Überflieger 2: Ferrofluid Application Research Goes Orbital analyzed the performance of ferrofluids, a technology that manipulates components such as rotors and switches using magnetized liquids and a magnetic field rather than mechanical systems, which are prone to wear and tear. This technology could lower the cost of materials for thermal management systems, reduce the need for maintenance and repair, and help avoid equipment failure. The paper discusses possible improvements to the thermal switch, including optimizing the geometry to better manage heat flow.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
A digital rendering of the completed Axiom Station, which includes the Payload, Power, and Thermal Module, Habitat 1, an airlock, Habitat 2, and the Research and Manufacturing Facility.Credits: Axiom Space In coordination with NASA, Axiom Space modified its planned assembly sequence to accelerate its ability to operate as a viable free-flying space station and reduce International Space Station reliance during assembly.
NASA awarded Axiom Space a firm-fixed price, indefinite-delivery, indefinite-quantity contract in January 2020, as the agency continues to open the space station for commercial use. The contract provides insight into the development of at least one habitable commercial module to be attached to the space station with the goal of becoming a free-flying destination in low Earth orbit prior to retirement of the orbiting laboratory in 2030.
The initial Axiom Space plan was to launch and attach its first module, Habitat 1, to the space station, followed by three additional modules.
Under the company’s new assembly sequence, the Payload, Power, and Thermal Module will launch to the orbiting laboratory first, allowing it to depart as early as 2028 and become a free-flying destination known as Axiom Station. In free-flight, Axiom Space will continue assembly of the commercial destination, adding the Habitat 1 module, an airlock, Habitat 2 module, and the Research and Manufacturing Facility.
“The updated assembly sequence has been coordinated with NASA to support both NASA and Axiom Space needs and plans for a smooth transition in low Earth orbit,” said Angela Hart, manager, Commercial Low Earth Orbit Development Program at NASA’s Johnson Space Center in Houston. “The ongoing design and development of commercial destinations by our partners is critical to the agency’s plan to procure services in low Earth orbit to support our needs in microgravity.”
The revised assembly sequence will enable an earlier departure from the space station, expedite Axiom Station’s ability to support free-flight operations, and ensure the orbiting laboratory remains prepared for the U.S. Deorbit Vehicle and end of operational life no earlier than 2030.
“The International Space Station has provided a one-of-a-kind scientific platform for nearly 25 years,” said Dana Weigel, manager, International Space Station Program at NASA Johnson. “As we approach the end of space station’s operational life, it’s critically important that we look to the future of low Earth orbit and support these follow-on destinations to ensure we continue NASA’s presence in microgravity, which began through the International Space Station.”
NASA is supporting the design and development of multiple commercial space stations, including Axiom Station, through funded and unfunded agreements. The current design and development phase will be followed by the procurement of services from one or more companies.
NASA’s low Earth orbit microgravity strategy builds on the agency’s extensive human spaceflight experience to advance future scientific and exploration goals. As the International Space Station nears the end of operations, NASA plans to transition to a new low Earth orbit model to continue leveraging microgravity benefits. Through commercial partnerships, NASA aims to maintain its leadership in microgravity research and ensure continued benefits for humanity.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The Spot the Station app was developed in collaboration with the public through a series of crowdsourcing competitions.NASA In its 25th year of operations, the International Space Station continues to symbolize discovery and cooperation for the benefit of humanity. Since 2012, observers have interacted with the space station through NASA’s Spot the Station website, a web browser-based tool that includes interactive maps for users to track the station and find viewpoints closest to their location.
A decade after the website’s release, NASA sought to enhance public access to this capability with a mobile app. NASA released the Spot the Station app on IOS and Android in 2023. As of Dec. 2024, it has more than 770,000 users in 227 countries and territories around the globe, according to Ensemble, who NASA contracts to maintain support of the app.
Revamping the Spot the Station experience was more than just an opportunity for NASA to make improvements; it allowed NASA to gather direct input from users by involving them in the development of the new app. Space Operations web and platform lead, Allison Wolff, pitched the idea to publicly crowdsource the app’s development.
In 2022, Wolff and her team supported the release of three separate crowdsourcing competitions, where global communities were invited to design key components of the new Spot the Station app. Participants submitted functional designs, including an augmented reality component not offered on the web version and interfaces for screens such as login and sign-up windows. Multiple winners were awarded prizes totaling $8,550 across the three challenges.
As the former Innovation Strategist in NASA’s Center of Excellence for Collaborative Innovation, part of the agency’s Prizes, Challenges, and Crowdsourcing program, Wolff was well acquainted with the ingenuity and results that stem from public-private collaborations.
“NASA strives to incorporate inclusion and innovation into how we operate. We also collaborate with minds outside the agency because the best ideas can come from very surprising places,” said Wolff.
Not only were the winning designs used in the final product, but the development team gained valuable feedback and worldwide perspectives from everyone who participated in the competition.
“When you use the power of the crowd and get a consistent message about a component or an interface, that’s a good indicator of what is user-friendly,” said Wolff.
Crowdsourcing continues to enhance the app’s functionality, including translating the app into six languages, including Spanish, French, and German, thanks to user contributions. In addition, the app’s code is open source, enabling anyone to modify and use the code for their own projects and support the tool’s growth. NASA will continue to update and improve the app with feedback from the public.

Photographers at NASA capture the sunset on Tuesday, Jan. 30, 2024, near the headquarters building of the agency’s Kennedy Space Center in Florida.NASA/Ben Smegelsky As NASA’s Kennedy Space Center in Florida wraps up a year that will see more than 90 government, commercial, and private missions launch from Florida’s Space Coast, a look to 2025 shows the missions, partnerships, projects, and programs at the agency’s main launch site will continue innovating, inspiring, and pushing the boundaries of exploration for the benefit of humanity.
“The next year promises to be another exciting one at Earth’s premier spaceport,” said Kennedy Center Director Janet Petro. “We have an amazing workforce, and when we join forces with industry and our other government partners, even the sky is no limit to what we can accomplish.”
New Year, New Missions to Space Station
NASA’s Commercial Crew Program (CCP), based out of Kennedy, and its commercial partner SpaceX plan two crew rotation missions to the International Space Station: NASA’s SpaceX Crew-10 and Crew-11. This also means the return of the Crew-9 mission and later Crew-10 during 2025. CCP continues working with Boeing toward NASA certification of the company’s Starliner system for future crew rotations to the orbiting laboratory.
NASA’s SpaceX Crew-10 members stand between Falcon 9 first-stage boosters at SpaceX’s HangarX facility at NASA’s Kennedy Space Center in Florida. From left are Mission Specialist Kirill Peskov of Roscosmos, Mission Specialist Takuya Onishi of JAXA (Japan Aerospace Exploration Agency), along with NASA astronauts Commander Anne McClain and Pilot Nichole Ayers. SpaceX “Operations in 2025 are a testament to NASA’s workforce carefully planning and preparing to safely execute a vital string of missions that the agency can depend on,” said Dana Hutcherson, CCP deputy program manager. “This is the 25th year of crewed operations for the space station, and we know that with every launch, we are sustaining a critical national asset and enabling groundbreaking research.”
NASA also plans several Commercial Resupply Services missions, utilizing SpaceX’s Dragon cargo spacecraft, Northrop Grumman’s Cygnus spacecraft, and the inaugural flight of Sierra Space’s cargo spaceplane, Dream Chaser. The missions will ferry thousands of pounds of supplies, equipment, and science investigations to the crew aboard the orbiting laboratory from NASA Kennedy and nearby Cape Canaveral Space Force Station.
The SpaceX Falcon 9 rocket carrying the Dragon spacecraft lifts off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida on Tuesday, Nov. 4, on the company’s 31st commercial resupply services mission for the agency to the International Space Station. Liftoff was at 9:29 p.m. EST. SpaceX In addition to the agency’s crewed flights, Axiom Space’s fourth crewed private spaceflight mission, Axiom Mission 4 – organized in collaboration with NASA through the International Space Station Program and operated by SpaceX – will launch to the orbital outpost.
Reestablishing Humanity’s Lunar Presence
Preparations for NASA’s Artemis II test flight mission are ramping up, with all major components for the SLS (Space Launch System) hardware undergoing processing at Kennedy, including the twin solid rocket boosters and 212-foot-tall core stage. Teams with EGS (Exploration Ground Systems) will continue stacking the booster segments inside the spaceport’s VAB (Vehicle Assembly Building). Subsequent integration and testing of the rocket’s hardware and Orion spacecraft will continue not only for the Artemis II mission, but for Artemis III and IV. Technicians also continue building mobile launcher 2, which will serve as the launch and integration platform for the SLS Block 1B configuration starting with Artemis IV.
Teams with NASA’s Exploration Ground Systems transport the agency’s 212-foot-tall SLS (Space Launch System) core stage into High Bay 2 at the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on Wednesday, Dec. 11, 2024. The one-of-a kind lifting beam is designed to lift the core stage from the transfer aisle to High Bay 2 where it will remain while teams stack the two solid rocket boosters on top of mobile launcher 1 for the SLS core stage.NASA/Kim Shiflett “Looking ahead to 2025, teams will embark on a transformative year as we integrate the flight hardware for Artemis II, while simultaneously developing the foundation for future Artemis missions that will reestablish humanity’s presence on the Moon,” said Shawn Quinn, EGS program manager.
A key part of the Artemis campaign, NASA’s CLPS (Commercial Lunar Payload Services) initiative will continue leveraging commercial partnerships to quickly land scientific instruments and technology demonstrations on the Moon. Firefly Aerospace’s first lunar CLPS flight, Blue Ghost Mission 1, will carry 10 NASA science and technology instruments to the lunar surface, including the Electrodynamic Dust Shield, a technology built by Kennedy engineers. Intuitive Machines, meanwhile, will embark on its second CLPS flight to the Moon. Providing the first in-situ resource utilization demonstration on the lunar surface, IM-2 will carry the Polar Resources Ice Mining Experiment-1 (PRIME-1), which features The Regolith and Ice Drill for Exploring New Terrain from Honeybee Robotics, as well as the Mass Spectrometer Observing Lunar Operations built by Kennedy. Both flights are targeted to lift off from Kennedy’s Launch Complex 39A during the first quarter of 2025.
As part of NASA’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign, Firefly Aerospace’s Blue Ghost Mission One lander will carry 10 NASA science and technology instruments to the Moon’s near side.Firefly Aerospace In development for Artemis IV and beyond, Gateway will be a critical platform for developing a sustained human presence beyond low Earth orbit. Deep Space Logistics (DSL) is the Gateway Program project office at Kennedy responsible for leading the development of a commercial supply chain in deep space. In 2025, DSL will continue developing the framework for the DSL-1 mission and working with commercial provider SpaceX to mature spacecraft design. Upcoming milestones include a system requirements review and preliminary design review to determine the program’s readiness to proceed with the detailed design phase supporting the agency’s Gateway Program and Artemis IV mission objectives.
Science Missions Studying Our Solar System and Beyond
NASA’s Launch Services Program (LSP), based at Kennedy, is working to launch three ambitious missions. Launching early in the year on a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California, SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) is a space telescope to survey the universe using visible and near-infrared light, observing more colors than ever before and allowing astronomers to piece together a three-dimensional map of the universe with stunning accuracy. Launching with SPHEREx, NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission will study how the mass and energy of the Sun’s corona transition into the solar wind.
NASA’s SPHEREx space observatory was photographed at BAE Systems in Boulder, Colorado, in November 2024 after completing environmental testing. The spacecraft’s three concentric cones help direct heat and light away from the telescope and other components, keeping them cool. BAE Systems IMAP (Interstellar Mapping and Acceleration Probe), scheduled to launch from Cape Canaveral in late 2025, will help map out thethe heliosphere – the magnetic environment surrounding and protecting our solar system. Carrying 10 instruments to make its observations, the IMAP mission is targeting the L1 Lagrange Point, an area between Earth and the Sun that is easy for spacecraft to maintain orbit, along with two Sun observing rideshare missions – NASA’s Carruthers Geocorona Observatory and the National Oceanic and Atmospheric Administration’s SWFO-L1 (Space Weather Follow-On at L1). Also launching in late 2025 on a Falcon 9 from Vandenberg is the second of two identical satellites, Sentinel-6B, which will monitor global sea levels with unprecedented precision. Its predecessor, Sentinel-6 Michael Freilich, has been delivering crucial data since it launched in 2020, and Sentinel-6B will ensure the continuation of this mission through 2030.
“Our missions launching next year will include groundbreaking technologies to help us learn more about the universe than ever before and provide new data for researchers that will have positive benefits here on Earth,” said LSP’s Deputy Program Manager Jenny Lyons.
NASA’s ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers) identical dual spacecraft are inspected and processed on dollies in a high bay of the Astrotech Space Operations Facility near the agency’s Kennedy Space Center in Florida on Thursday, Aug. 22, 2024. As the first multi-spacecraft orbital science mission to Mars, ESCAPADE’s twin orbiters will take simultaneous observations from different locations around the planet and reveal the real-time response to space weather and how the Martian magnetosphere changes over time.NASA/Kim Shiflett The program’s support for small satellite missions next year includes several missions to monitor the Sun, collect climate data, and more. NASA’s ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers) mission to explore Mars’ magnetosphere will lift off from Cape Canaveral’s Launch Complex 36 on NASA’s inaugural flight of Blue Origin’s New Glenn rocket. Some of these small satellite missions are part of NASA’s CubeSat Launch Initiative, which offers the next generation of scientists, engineers, and technologists a unique opportunity to conduct scientific research and develop and demonstrate novel technologies in space.
Building the Spaceport’s Future
Teams expect a busy year of construction projects to accommodate new missions, hardware, and milestones. In preparation for Artemis IV, mobile launcher 2 construction and modifications in the VAB’s High Bays 3 and 4 for the larger SLS Block 1B configuration will ramp up. Teams also will upgrade the spaceport’s Converter Compressor Facility (CCF) to meet the helium needs of its commercial launch partners and the Artemis campaign, increasing efficiency, reliability, and speed of pumping helium to rockets. Upgrades to the CCF’s internal infrastructure are also part of Kennedy’s plan to earn the U.S. Green Building Council’s Leadership in Energy and Environmental Design certification, joining nine other Kennedy facilities in achieving that rating.
Photographers at NASA capture the sunset on Tuesday, Jan. 30, 2024, near Vehicle Assembly Building at the agency’s Kennedy Space Center in Florida. The iconic Vehicle Assembly Building, currently used for assembly of NASA’s Space Launch System rocket for Artemis missions, remains the only building in which rockets were assembled that carried humans to the surface of another world. NASA/Ben Smegelsky “Kennedy’s spaceport will continue to see its launch cadence grow, and we have to meet our program and commercial partner needs in the most efficient way possible,” said Sasha Sims, deputy director of Kennedy’s Spaceport Integration and Services Directorate. “Process improvements and integrated approaches should improve the speed at which government and commercial construction takes place while also improving Kennedy’s infrastructure so that it’s robust, sustainable, and able to support America’s future in space.”
Driving down acquisition costs, increasing competition, and using innovative contracting mechanisms for construction are just some of the initiatives to maximize efficiency and reliability in 2025. The center’s “Critical Day” policy prohibits certain types of work during launches requiring full flight range support but will no longer apply to commercial launches where minimal flight range support is required, training events, static fires, exercises, tests, rehearsals, nor other activities leading up to or supporting launches. This policy change is expected to create more flexibility and free up over 150 days annually for construction, maintenance, and other essential work needed to keep the spaceport running smoothly.
Finally, Kennedy will continue carrying Apollo’s legacy through Artemis. Seeds that traveled aboard the Orion spacecraft during the Artemis I mission will be planted at the spaceport, honoring the legacy of the original Moon Trees that grew from seeds flown on Apollo 14. The Florida spaceport will become one of the select locations across the country where the “new generation” of Moon Trees will take root and provide living testimony to the agency’s continuing legacy of lunar exploration.
“With so many missions and initiatives on the horizon, I’m looking forward to another banner year at Kennedy Space Center,” Petro said. “We truly are launching humanity’s future.”
