Main Article

On September 7, 2024, Boeing’s Starliner spacecraft made a triumphant return to Earth after more than three months in space. Initially planned as a 10-day Crew Flight Test (CFT) mission, the spacecraft experienced delays that extended the mission significantly. Despite the unexpected issues that arose, NASA affirmed that astronauts aboard the spacecraft would have been safe. The mission represents a crucial step in the development of Starliner as a crew transport vehicle to the International Space Station (ISS).

Steve Stich, the manager of NASA’s Commercial Crew Program, emphasized the confidence NASA has in Starliner’s performance, saying, “If we’d have had a crew on board the spacecraft, we would have followed the same back-away sequence from the space station, the same deorbit burn and executed the same entry. And so it would have been a safe, successful landing with the crew on board.”

NASA and Boeing’s Approach to Safety

Safety has always been the top priority for both NASA and Boeing. The three-month delay in Starliner’s return was prompted by issues with the spacecraft’s thrusters as it approached the ISS. These technical problems, while concerning, allowed NASA and Boeing to reevaluate and troubleshoot the spacecraft’s systems thoroughly. In the words of Stich, “It’s always hard to have that retrospective look. If we’d had a model that would have predicted what we saw tonight perfectly, yeah, it looks like an easy decision to go say we could have had a crewed flight, but we didn’t have that.”

NASA decided to return the spacecraft without any crew. They made this choice after studying the situation carefully. This helped them make sure that any dangers to astronauts were removed before sending humans on board.

The Crew Flight Test (CFT) mission was supposed to be Starliner’s final test before entering regular service as a crew transport vehicle to the ISS. NASA astronauts Butch Wilmore and Suni Williams were initially set to return with the spacecraft, but the thruster issues prompted NASA to revise its plan.

After launching aboard Starliner on June 4, 2024, Wilmore and Williams expected to spend about 10 days in space. However, NASA announced in late August that Starliner would return uncrewed. The decision resulted in the reassignment of Wilmore and Williams to ISS Expedition 71. They will now spend approximately ten months in space and return to Earth aboard SpaceX’s Crew Dragon in 2025.

This shift in plans, while unforeseen, has allowed NASA and Boeing to continue refining the spacecraft’s capabilities. Despite the setbacks, Starliner’s return to Earth went off without a hitch, landing at White Sands Missile Range in New Mexico at 12:01 a.m. EDT (0401 GMT) on September 7, 2024.

As Starliner approached the ISS for docking, engineers observed irregularities with the spacecraft’s orbital maneuvering and attitude control (OMAC) thrusters. These thrusters are crucial for the precise movements necessary to approach, dock, and undock from the ISS. The issue caused a significant delay, and NASA made the decision to delay the spacecraft’s return until they could fully understand and address the problem.

Over the next few months, extensive tests were conducted in White Sands, New Mexico, where NASA and Boeing engineers worked tirelessly to recreate the issues experienced in space. Ultimately, the spacecraft returned safely, with parachutes deploying as expected and landing softly in the New Mexico desert. This achievement demonstrated Starliner’s robustness despite the challenges encountered.

While Starliner completed its mission without its crew, astronauts Wilmore and Williams continue their extended stay aboard the ISS. The two astronauts will now return to Earth aboard a Crew Dragon spacecraft in February 2025. Instead of the planned 10 days in space, they will have spent ten months in orbit.

Despite the delays and challenges, Starliner’s safe return is an important milestone for NASA’s Commercial Crew Program. The program, which seeks to develop spacecraft that can safely transport astronauts to and from the ISS, now boasts two key players: SpaceX’s Crew Dragon and Boeing’s Starliner.

While SpaceX has already completed multiple successful crewed missions, Boeing’s Starliner has faced its fair share of delays. However, the safe landing of the spacecraft in New Mexico marks a significant step forward, bringing Starliner closer to operational status.

According to NASA Administrator Bill Nelson, “Starliner’s safe return is a testament to the dedication and perseverance of both NASA and Boeing teams. We are committed to ensuring the safety of our astronauts, and this mission brings us one step closer to making Starliner an integral part of our human spaceflight program.

With Starliner’s successful landing, both NASA and Boeing look to the future of human space exploration. The spacecraft, once fully operational, will play a critical role in ferrying astronauts to the ISS and potentially other destinations in low Earth orbit.

Boeing’s efforts to address and resolve the technical challenges faced during the CFT mission demonstrate the company’s resilience and determination. As Starliner continues to undergo rigorous testing and refinement, NASA remains confident that the spacecraft will soon be ready to transport astronauts regularly.

Starliner’s role in NASA’s future space missions goes beyond just ISS transport. The spacecraft’s design is adaptable, and Boeing has hinted at potential uses for missions to the Moon or Mars. With NASA’s Artemis program ramping up, Starliner could one day be a part of humanity’s return to the lunar surface.

The Role of NASA’s Commercial Crew Program

The Commercial Crew Program (CCP) has been a cornerstone of NASA’s efforts to foster collaboration with private companies in advancing human space exploration. By partnering with Boeing and SpaceX, NASA has sought to develop multiple spacecraft capable of transporting astronauts safely to and from space. This collaboration allows NASA to focus on deep space exploration, while companies like Boeing and SpaceX focus on low Earth orbit operations.

Table 1: NASA’s Commercial Crew Program Key Players

The system will enhance scientific operations by enabling real-time data transmission and high-definition video streaming.
The technology provides redundancy for existing communication links, offering increased safety and reliability.
The LSCS system will be tested on the moon during a robotic mission scheduled for late 2024.
The partnership is part of a larger effort to develop a sustainable lunar infrastructure for future missions.

A New Era in Lunar Communication: Axiom Space and Nokia’s Groundbreaking Partnership

The race to establish a sustainable human presence on the moon has led to some of the most innovative partnerships in space exploration history. Among these, the collaboration between Axiom Space and Nokia stands out as a significant leap forward. Announced on August 21, 2024, this partnership aims to integrate cutting-edge 4G/LTE wireless communication technologies into the spacesuits that Axiom Space is developing for NASA’s Artemis program.

At the heart of the Axiom-Nokia collaboration is the Lunar Surface Communications System (LSCS), a sophisticated communication network designed to support the Artemis spacesuits. The LSCS system will consist of two main components:

Network in a Box: This includes a base station, antennas, and other supporting systems installed on the Human Landing Services lander.
User Module: Integrated within Axiom’s spacesuits, this module will enable astronauts to connect to the LSCS seamlessly.

The system aims to provide redundancy for existing communication channels, such as UHF and Wi-Fi, while significantly increasing bandwidth. This enhancement allows for high-definition video streaming, real-time data transmission, and improved communication between astronauts and mission control.

The Artemis program, a critical part of NASA’s long-term lunar exploration goals, seeks to return humans to the moon by 2026. Axiom Space’s involvement in developing the next-generation extravehicular activity (EVA) suits is crucial to this mission. The addition of Nokia’s 4G/LTE technology will elevate the capabilities of these suits, allowing astronauts to perform more complex tasks with higher efficiency.

Russell Ralston, Axiom Space’s executive vice president of extravehicular activity, highlighted the importance of this technology in a recent interview. “From a suit perspective, we like this because it will give us a lot more capability and it gives us a little bit more redundancy in the communications,” he said. The LSCS technology offers a unique blend of reliability and versatility, providing astronauts with multiple communication options based on mission requirements.

One of the most significant benefits of the LSCS technology is its potential to revolutionize scientific operations on the lunar surface. The system enables scientists and geologists supporting the mission from Earth to gain a clearer, real-time understanding of the crew’s observations. By streaming high-definition video directly from the suit’s cameras, mission control and research teams can collaborate more effectively, making informed decisions with minimal delay.

“From a scientific perspective, what it means is all of the scientists and geologists supporting the NASA mission in real-time will have much better insight into what the crew is seeing,” Ralston explained. “People will connect with the mission a lot more closely when they can see it in such rich detail.”

Axiom Space and Nokia Partnering for Cutting-Edge Wireless Spacesuit Technology

Before being incorporated into Axiom’s spacesuits, Nokia’s LSCS system will undergo rigorous testing during the IM-2 mission, the second robotic lunar lander mission by Intuitive Machines. This mission, scheduled for late 2024, will test the system’s ability to provide communication between the lander, a rover, and a “hopper” developed by Intuitive Machines. While the success of this mission is not a must for using LSCS on Axiom’s suits, it provides valuable insights for future Artemis missions.

Thierry Klein, president of Bell Labs Solutions Research at Nokia, noted that the technology could be adapted for future missions involving a lunar rover. Nokia is also exploring how this technology could be utilized in a commercial lunar economy over the next 10 to 15 years through its participation in DARPA’s LunA-10 study.

NASA’s commitment to developing advanced spacesuit technology is reflected in its recent $57.5 million task order to Axiom Space, part of the larger Exploration Extravehicular Activity Services (xEVAS) contract. This task order funds the integration of the LSCS technology into the Artemis suits, marking a significant milestone in the development process.

Axiom Space is now entering the critical design review (CDR) phase of suit development, a period that will continue into early 2025. “We’re approaching that point in time where the design is really solidifying,” Ralston said. He emphasized the importance of having Nokia’s technology incorporated before the CDR phase is completed, ensuring that the final design fully integrates the LSCS capabilities.

Artemis 3 Mission	No earlier than 2026	First use of Axiom’s LSCS-equipped spacesuits on a crewed lunar mission.

The LSCS technology is designed to be user-friendly, with seamless integration into the spacesuits. Astronauts can choose between different communication options based on their mission needs, whether it be UHF, Wi-Fi, or 4G/LTE. This flexibility allows for tailored communication strategies that can adapt to the unique challenges of each lunar mission.

Moreover, the LSCS system is built to operate efficiently at distances of up to two kilometers from the lander, meeting NASA’s requirements for the Artemis 3 mission. However, Nokia’s testing has shown that the system can potentially exceed this range in certain configurations, opening the door for even more ambitious lunar exploration activities in the future.

The collaboration between Axiom Space and Nokia is not just about enhancing communication for lunar missions; it’s part of a broader vision to establish a sustainable lunar economy. Nokia’s participation in DARPA’s LunA-10 study reflects this ambition. The study explores how communication networks like LSCS could support commercial activities on the moon, from mining operations to lunar tourism.

As the technology matures, it could become a critical infrastructure component for a thriving lunar economy, enabling everything from autonomous robotic operations to real-time video feeds for remote lunar workers.

The integration of Nokia’s LSCS into Axiom’s spacesuits represents a new standard in spacesuit technology. By combining cutting-edge wireless communication with robust, adaptable suit design, Axiom Space is setting the stage for a new era of lunar exploration.

The modularity of the LSCS allows for future upgrades and modifications, ensuring that the suits remain relevant as NASA and its partners push the boundaries of human exploration.

NASA’s Lunar Orbiter Discovers Hidden Tunnels Beneath the Moon’s Surface

The presence of conduits below the lunar surface has been theorized and extensively debated for at least 50 years. The analysis of NASA Lunar Reconnaissance Orbiter (LRO) radar data reveals what lies below the Mare Tranquillitatis. A team of international scientists, led by the University of Trento, Italy, has published a research study making a milestone discovery about the Moon. For the first time, scientists have demonstrated the existence of a tunnel in the lunar subsurface, which appears to be an empty lava tube. The research study was published on July 15, 2024, in the journal Nature Astronomy and is the result of an international collaboration.

Evidence of Lunar Caves

“These caves have been theorized for over 50 years, but it is the first time ever that we have demonstrated their existence,” explains Lorenzo Bruzzone, professor at the University of Trento. How was this demonstration achieved? Bruzzone explains: “In 2010, as part of the ongoing LRO NASA mission, the Miniature Radio-Frequency (Mini-RF) instrument acquired data that included a pit in Mare Tranquilitatis. Years later, we have reanalyzed these data with complex signal processing techniques we have recently developed and discovered radar reflections from the area of the pit that are best explained by an underground cave conduit. This discovery provides the first direct evidence of an accessible lava tube under the surface of the Moon.”

Techniques and Technology in Lunar Research

“Thanks to the analysis of the data we were able to create a model of a portion of the conduit,” continues Leonardo Carrer, a researcher at the University of Trento. “The most likely explanation for our observations is an empty lava tube.” The Mini-RF principal investigator, Wes Patterson, from the Johns Hopkins Applied Physics Laboratory adds, “This research demonstrates both how radar data of the Moon can be used in novel ways to address fundamental questions for science and exploration and how crucial it is to continue collecting remotely sensed data of the Moon. This includes the current LRO mission and, hopefully, future orbiter missions.”

Implications for Lunar Exploration

The study, partially funded by the Italian Space Agency, also involved researchers from the University of Padua and La Venta Geographic Explorations APS, who contributed to the geological analyses and the modeling of the identified conduit. The study has scientific importance and implications for the development of missions to the Moon, where the environment is hostile to human life. Surface temperatures on the illuminated side of the Moon can reach 127°C (261°F), while temperatures on the unilluminated side can drop to -173°C (-279°F). Cosmic and solar radiation can be as much as 150 times more powerful on the lunar surface than we experience on Earth, and there is a constant threat of meteorite impact. These conditions drive a need to find safe sites for the construction of infrastructure that can support sustained exploration. Caves such as this one offer a solution to that problem.
