Networks Keeping NASA’s Artemis II Mission Connected
NASA’s Artemis II mission will transport four astronauts around the Moon, bringing the agency one step closer to sending the first astronauts to Mars. Throughout Artemis II, astronaut voice, images, video, and vital mission data must traverse thousands of miles, carried on signals from NASA’s communications systems.
Through Artemis, NASA is establishing an enduring presence in space and exploring more of the Moon than ever before. To achieve this, Artemis missions rely on both the Near Space Network and the Deep Space Network. These networks, with oversight by NASA’s SCaN (Space Communications and Navigation) Program office, use global infrastructure and relay satellites to ensure seamless communications and tracking as Orion launches, orbits Earth, travels to the Moon, and returns home.
“Robust space communications aren’t optional; they’re the essential link that unites the crew and the exploration team on Earth to ensure safety and mission success, as I learned firsthand living and working aboard the International Space Station,” said Ken Bowersox, associate administrator for NASA’s Space Operations Mission Directorate at the agency’s headquarters in Washington. “From real-time conversations with mission controllers, to the data that drives critical decisions and research, and even calls home — space communications keep astronauts connected to mission managers, technical experts, loved ones, and everyone on Earth who wants to share in the excitement of our exploration missions. As we push farther into deep space, reliable communications links will enable more challenging missions and maximize the benefit for all of us on Earth.”

Specialists will operate its networks in tandem to enable data exchange between spacecraft and mission controllers on Earth. NASA’s Mission Control Center at the agency’s Johnson Space Center in Houston will track the Space Launch System rocket, Interim Cryogenic Propulsion Stage, and Orion spacecraft through coordinated handoffs between the networks’ multiple assets on Earth and in space for the duration of the mission.
Using ground stations around the globe and a fleet of relay satellites, the Near Space Network will provide communications and navigation services during multiple stages of the Artemis II mission operations. The network, managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland, has a long legacy of supporting human spaceflight missions near Earth.
After Orion’s translunar injection burn, which will set the spacecraft on its planned orbit around the Moon, primary communications support will transition to the Deep Space Network, managed by NASA’s Jet Propulsion Laboratory in Southern California. The network’s international array of giant radio antennas, located in California, Spain, and Australia, provides a near-continuous connection to Orion and its crew.

“Reliable communications are the lifeline of human spaceflight,” said Kevin Coggins, deputy associate administrator for the SCaN Program at NASA Headquarters. “Our networks help make missions like Artemis II possible and set the stage for even more ambitious space exploration in the years ahead. These achievements are driven not only by NASA’s infrastructure but also by strong collaboration with our commercial partners, who play a critical role in advancing the capabilities and resilience of space communications.”

In addition to traditional radio network support, the spacecraft will host the Orion Artemis II Optical Communications System, a laser communications terminal that will transmit real science and crew data over laser links. Demonstrations like the recent Deep Space Optical Communications payload have proven laser communications systems can send more than 100 times more data than comparable radio networks, even millions of miles away from Earth. While laser communications will not be on Artemis III, the Orion Artemis II Optical Communications System could pave the way for future laser communications systems at the Moon and Mars.

NASA / Dave RyanThe Orion Artemis II Optical Communications System payload is only one piece of NASA’s larger mission to improve lunar and deep space communications. Orion will experience a planned communications blackout lasting approximately 41 minutes. The blackout will occur as the spacecraft passes behind the Moon, blocking radio frequency signals to and from Earth. Similar blackouts occurred during the Apollo-era missions and are expected when using an Earth-based network infrastructure. When Orion reemerges from behind the Moon, the Deep Space Network will quickly reacquire Orion’s signal and restore communications with mission control. These planned blackouts remain an aspect of all missions operating on or around the Moon’s far side.
Each Artemis mission will build upon existing capabilities, including data processing and handling. For the Artemis II flight test, data from Orion will be compressed after it reaches Earth to manage the large amount of information. Data compression will reduce image and video quality and give priority to crew communications and mission data.

This network of orbiting satellites will deliver persistent, high-bandwidth communications and navigation services for astronauts, landers, and orbiters on and around the lunar surface. In 2024, NASA selected Intuitive Machines to develop the first set of lunar relays for demonstration during the Artemis III lunar surface mission.
From liftoff to splashdown, NASA’s evolving networks will serve as the crew’s link home, ensuring that humanity’s return to the Moon stays connected every step of the way.

NASA Telescopes Spot Surprisingly Mature Cluster in Early Universe
A new discovery captures the cosmic moment when a galaxy cluster – among the largest structures in the universe – started to assemble only about a billion years after the big bang, one or two billion years earlier than previously thought. This result, made using NASA’s Chandra X-ray Observatory and James Webb Space Telescope, will lead astronomers to rethink when and how the largest structures in the universe formed. The findings are described in a paper published [Wednesday] in the journal Nature.
The object, known as JADES-ID1 for its location in the “JWST Advanced Deep Extragalactic Survey” (JADES) has a mass about 20 trillion times that of the Sun. Astronomers classify JADES-ID1 as a “protocluster” because it is currently undergoing an early, violent phase of formation and will one day turn into a galaxy cluster. However, JADES-ID1 is found at a much larger distance – corresponding to a much earlier time in the universe – than astronomers expected for such systems, providing a new mystery of how it could form so quickly.
“This may be the most distant confirmed protocluster ever seen,” said Akos Bogdan of the Center for Astrophysics | Harvard & Smithsonian (CfA) who led the study. “JADES-ID1 is giving us new evidence that the universe was in a huge hurry to grow up.”
Galaxy clusters contain hundreds or even thousands of individual galaxies immersed in enormous pools of superheated gas, along with large amounts of unseen dark matter. Astronomers use galaxy clusters to measure the expansion of the universe and the roles of dark energy and dark matter, among other important cosmic studies.
“It’s very important to actually see when and how galaxy clusters grow,” said co-author Gerrit Schellenberger, also of CfA. “It’s like watching an assembly line make a car, rather than just trying to figure out how a car works by looking at the finished product.”
The Chandra and Webb data reveal that JADES-ID1 contains the two properties that confirm the presence of a protocluster: a large number of galaxies held together by gravity (Webb sees at least 66 potential members) that are also sitting in a huge cloud of hot gas (detected by Chandra). As a galaxy cluster forms, gas falls inward and is heated by shock waves, reaching temperatures of millions of degrees and glowing in X-rays.
What makes JADES-ID1 exceptional is the remarkably early time when it appears in cosmic history. Most models of the universe predict that there likely would not be enough time and a large enough density of galaxies for a protocluster of this size to form only a billion years after the big bang. The previous record holder for a protocluster with X-ray emission is seen much later, about three billion years after the big bang.
“We thought we’d find a protocluster like this two or three billion years after the big bang – not just one billion,” said co-author Qiong Li from the University of Manchester in the UK. “Before, astronomers found surprisingly large galaxies and black holes not long after the big bang, and now we’re finding that clusters of galaxies can also grow rapidly.”
After billions of years JADES-ID1 should evolve from a protocluster into a massive galaxy cluster like those we see much closer to Earth.
To find JADES-ID1, astronomers combined deep observations from both Chandra and Webb. By design, the JADES field overlaps with the Chandra Deep Field South, the site of the deepest X-ray observation ever conducted. This field is thus one of the few in the entire sky where a discovery such as this could be made. In an earlier study, a team of researchers led by Li and Conselice found five other proto-cluster candidates in the JADES field, but only in JADES-ID1 are the galaxies embedded in hot gas. Only JADES-ID1 possesses enough mass for an X-ray signal from hot gas to be expected.
“Discoveries like this are made when two powerful telescopes like Chandra and Webb stare at the same patch of sky at the limit of their observing capabilities,” said co-author Christopher Conselice, also from the University of Manchester. “A challenge for us now is to understand how this protocluster was able to form so quickly.”

Visual DescriptionThis composite image features what may be the most distant protocluster ever found; a region of space where a large number of young galaxies are being held together by gravity and hot gas. The image is presented twice, once with, and once without, annotations.
The image includes scores of glowing dots and specks of light, in white and golden hues, set against the blackness of space. This layer of the composite visual is from a deep infrared imaging project undertaken by the James Webb Space Telescope. The specks range from relatively large oval galaxies with discernible spiral arms, and glowing balls with gleaming diffraction spikes, to minuscule pinpoints of distant light. Several of those pinpoints have been circled in the annotated image, as they are part of the distant protocluster.
Layered onto the center of this image is a neon blue cloud. This cloud represents hot X-ray gas discovered by Chandra in the deepest X-ray observation ever conducted. In the annotated image, a thin white square surrounds the blue cloud. This represents Chandra’s field of observation. The X-rays from the distant protocluster located within this box are included in the composite image.
The protocluster, dubbed JADES-1, has a mass of about 20 trillion suns. It is located some 12.7 billion light-years from Earth, or just a billion years after the big bang. The discovery of a protocluster of this size, at this epoch in the early universe, will lead scientists to re-examine their ideas for how galaxy clusters first appeared in the universe.
