NASA has selected multiple companies to expand the agency’s Near Space Network’s commercial direct-to-Earth capabilities services, which is a mission-critical communication capability that allows spacecraft to transmit data directly to ground stations on Earth.
The work will be awarded under new Near Space Network services contracts that are firm-fixed-price, indefinite-delivery/indefinite-quantity contracts. Project timelines span from February 2025 to September 2029, with an additional five-year option period that could extend a contract through Sept. 30, 2034. The cumulative maximum value of all Near Space Network Services contracts is $4.82 billion.
Some companies received multiple task orders for subcategories identified in their contracts. Awards are as follows:
Intuitive Machines of Houston will receive two task order awards on its contract for Subcategory 1.2 GEO to Cislunar Direct to Earth (DTE) Services and Subcategory 1.3 xCislunar DTE Services to support NASA’s Lunar Exploration Ground Segment, providing additional capacity to alleviate demand on the Deep Space Network and to meet the mission requirements for unique, highly elliptical orbits. The company also previously received a task order award for Subcategory 2.2 GEO to Cislunar Relay Services. Kongsberg Satellite Services of Tromsø, Norway, will receive two task order awards on its contract for Subcategory 1.1 Earth Proximity DTE and Subcategory 1.2 to support science missions in low Earth orbit and NASA’s Lunar Exploration Ground Segment, providing additional capacity to alleviate demand on the Deep Space Network. SSC Space U.S. Inc. of Horsham, Pennsylvania, will receive two task order awards on its contract for Subcategories 1.1 and 1.3 to support science missions in low Earth orbit and to meet the mission requirements for unique, highly elliptical orbits. Viasat, Inc. of Duluth, Georgia, will be awarded a task order on its contract for Subcategory 1.1 to support science missions in low Earth orbit. The Near Space Network’s direct-to-Earth capability supports many of NASA’s missions ranging from climate studies on Earth to research on celestial objects. It also will play a role in NASA’s Artemis campaign, which calls for long-term exploration of the Moon.
NASA’s goal is to provide users with communication and navigation services that are secure, reliable, and affordable, so that all NASA users receive the services required by their mission within their latency, accuracy, and availability requirements.
These awards demonstrate NASA’s ongoing commitment to fostering strong partnerships with the commercial space sector, which plays an essential role in delivering the communications infrastructure critical to the agency’s science and exploration missions.
As part of the agency’s SCaN (Space Communications and Navigation) Program, teams at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, will carry out the work of the Near Space Network. The Near Space Network provides missions out to 1.2 million miles (2 million kilometers) with communications and navigation services, enabling spacecraft to exchange critical data with mission operators on Earth. Using space relays in geosynchronous orbit and a global system of government and commercial direct-to-Earth antennas on Earth, the network brings down terabytes of data each day.

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.

Credit: NASA/Keegan Barber Liechtenstein signed the Artemis Accords Friday during a ceremony hosted by NASA Deputy Administrator Pam Melroy at the agency’s headquarters in Washington, becoming the 52nd nation to commit to the responsible exploration of space for all humanity.
“Today, as Liechtenstein signs the Artemis Accords, we take another step forward together, united by the promise of international cooperation and discovery,” said Melroy. “Liechtenstein’s commitment strengthens our vision, where space is explored with peace, transparency, and sustainability as guiding principles. With each new signatory, the Artemis Accords community adds fresh energy and capabilities to ensure the benefits of space reach the entire world.”
Director of Liechtenstein’s Office for Communications Rainer Schnepfleitner signed the Artemis Accords on behalf of Liechtenstein. The Ambassador of the Principality of Liechtenstein to the United States Georg Sparber and U.S. Ambassador to the Swiss Confederation and the Principality of Liechtenstein Scott Miller also participated in the event.
“With its participation in the Artemis Accords, Liechtenstein looks forward to advancing space exploration among a strong group of like-minded countries committed to the peaceful use of space for the benefit of all humanity,” Sparber said.
The United States, led by NASA and the U.S. Department of State, and seven other initial signatory nations established the Artemis Accords in 2020, identifying a set of principles promoting the beneficial use of space for humanity. Since then, signatories have expanded to represent a quarter of the world’s countries, with 19 countries signing in 2024.
In addition to an increase in numbers, the Artemis Accords signatories, representing every region of the world, continued to build consensus this year and make significant progress in implementing the accords principles.
NASA co-chaired the Artemis Accords Principals’ Meeting in October, which brought together 42 nations and furthered discussions on the safe and responsible use of space. They agreed on recommendations for non-interference, interoperability, release of scientific data, long-term sustainability guidelines, and registration of space objects to advance implementation.
The Artemis Accords are grounded in the Outer Space Treaty and other agreements including the Registration Convention, the Rescue and Return Agreement, as well as best practices for responsible behavior that NASA and its partners have supported, including the public release of scientific data.

NASA has taken a big step forward in how engineers will assemble and stack future SLS (Space Launch System) rockets for Artemis Moon missions inside the Vehicle Assembly Building (VAB) at the agency’s Kennedy Space Center in Florida.
The VAB’s High Bay 2 has been outfitted with new tooling to facilitate the vertical integration of the SLS core stage. That progress was on full display in mid-December when teams suspended the fully assembled core stage 225 feet in the air inside the high bay to complete vertical work before it is stacked on mobile launcher 1, allowing teams to continue solid rocket booster stacking simultaneously inside High Bay 3 for Artemis II.
The fully assembled SLS (Space Launch System) core stage for the Artemis II test flight is suspended 225 feet in the air inside the newly renovated High Bay 2 at Kennedy’s Vehicle Assembly Building. The core stage was lifted to enable engineers to complete work before it is stacked on mobile launcher 1 with other rocket elements. With the move to High Bay 2, technicians now have 360-degree tip to tail access to the core stage, both internally and externally.NASA With the move to High Bay 2, technicians with NASA and Boeing now have 360-degree tip to tail access to the core stage, both internally and externally. Michigan-based supplier Futuramic Tool and Engineering led the design and build of the Core Stage Vertical Integration Center tool that will hold the core stage in a vertical position.
“High Bay 2 tooling was originally scheduled to be complete for Artemis III. We had an opportunity to get it done earlier and that will put us in a good posture to complete work earlier than planned prior to moving the core stage for Artemis II into the full integrated stack over into in High Bay 3,” said Chad Bryant, deputy manager of the NASA SLS Stages Office. “This gives us an opportunity to go in and learn how to rotate, lift, and move the core stage into the high bay.”
This move also doubles the footprint of useable space within the VAB, giving engineers access to both High Bay 2 and High Bay 3 simultaneously, while also freeing up space at NASA’s Michoud Assembly Facility in New Orleans to continue work on the individual elements for future SLS core stages.
High Bay 2 has a long history of supporting NASA exploration programs: during Apollo, High Bay 2, one of four high bays inside the VAB, was used to stack the Saturn V rocket. During the Space Shuttle Program, the high bay was used for external tank checkout and storage and as an extra storage area for the shuttle.
Under the new assembly model beginning with Artemis III, all the major structures for the SLS core stage will continue to be fully produced and manufactured at NASA Michoud. Upon completion of manufacturing and thermal protection system application, the engine section will be shipped to Kennedy for final outfitting.
The 212-foot-tall SLS (Space Launch System) core stage for NASA Artemis II is seen being moved from a horizontal position to a vertical position in High Bay 2 at the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida. With the move to High Bay 2, NASA and Boeing technicians now have 360-degree access to the core stage both internally and externally. (NASA) “Core stage 3 marks a significant change in the way we build core stages,” said Steve Wofford, manager of the SLS Stages Office. “The vertical capability in High Bay 2 allows us to perform parallel processing from the top to bottom of the stage. It’s a much more efficient way to build core stages. This new capability will streamline final production efforts, allowing our team to have 360-degree access to the stage, both internally and externally.”
The fully assembled core stage for Artemis II arrived July 23, 2024, at Kennedy, where it remained horizontal inside the VAB transfer aisle until its recent lift into the newly outfitted high bay.
Teams at NASA Michoud are outfitting the remaining core stage elements for Artemis III and preparing to horizontally join them. The four RS-25 engines for the Artemis III mission are complete at NASA’s Stennis Space Center in Bay St. Louis, Mississippi, and will be transported to NASA Kennedy in 2025. Major core stage and exploration upper stage structures are in work at NASA Michoud for Artemis IV and beyond.
NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, supporting ground systems, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.
