Introduction

Humanity’s dream of traveling to distant stars is inching closer to reality. Project Hyperion is an initiative aiming to design humanity’s first interstellar generation ship capable of supporting human life for the hundreds of years required for interstellar travel. Unlike traditional methods that focus on short-duration missions or robotic probes, this project seeks to create a self-sustaining spacecraft to transport humans to nearby star systems.

The project is particularly exciting because it draws upon modern technologies, interdisciplinary collaboration, and bold design ideas. It offers a prize competition for the best designs, with contributions from around the world to address not only technological challenges but also the societal, biological, and cultural aspects of such a monumental journey.

The History of Generation Ships

The idea of generation ships goes back over a century. Early pioneers like Robert H. Goddard, considered the father of modern rocketry, imagined ships that could travel through space over long periods. His 1918 proposal outlined the possibility of atomic-powered ships carrying humans on interstellar voyages. Similarly, Konstantin Tsiolkovsky in the 1920s expanded on these ideas, suggesting ships that would rely on human crews for the entire journey rather than on suspended animation or robotic probes.

In the 1960s, Robert Enzmann, a NASA scientist, designed the “Enzmann Starship”, a ship that could carry 200 people on a journey to the stars. This design, along with others, laid the groundwork for the concept of generation ships and continues to influence current thinking in Project Hyperion.

Why Generation Ships?

The distances between stars are vast, and even the closest star to Earth, Proxima Centauri, is over 4 light-years away. Current propulsion methods, like conventional rocket engines, would take thousands of years to reach even the nearest stars. Generation ships overcome this issue by relying on slower but more sustainable propulsion methods like fusion. They are designed to support multiple generations of humans as they travel across space.

The self-sustaining nature of a generation ship makes it the only feasible option for long-term space travel. By creating a closed-loop ecological system onboard, it ensures the crew has access to essential resources like air, water, and food. As Project Hyperion aims to demonstrate, this approach offers the possibility of humans living, working, and even thriving in space for generations.

Challenges of Designing a Generation Ship

Designing a generation ship involves a multitude of challenges, which have been addressed by various teams working under Project Hyperion.

1. Propulsion

One of the most critical elements of any interstellar mission is propulsion. To travel to another star system, Project Hyperion suggests relying on fusion-based propulsion, which can allow the spacecraft to reach speeds up to 10-20% of the speed of light. While fusion technology is still in its infancy, this is one of the most promising methods of propulsion for long-distance interstellar travel.

2. Life Support Systems

For the generation ship to work, it must have bioregenerative life support that can continuously regenerate air, water, and food over many generations. The Biosphere 2 project is a prime example of how human life can be sustained in closed environments, offering insights into how the Project Hyperion ship could support life for centuries. The crew will need to recycle resources efficiently, grow food in space, and keep the environment stable.

3. Artificial Gravity

To ensure the health of the crew, artificial gravity is necessary to prevent bone loss and muscle atrophy, which are common in low-gravity environments. By rotating parts of the spacecraft, Project Hyperion would simulate gravity, creating a livable space for human health.

The Society Aboard the Generation Ship

In addition to the technical and biological challenges, there is also the need to address the sociocultural factors of life aboard a generation ship. Over the course of 250 years, the passengers will experience changes in society, culture, and genealogy.

Maintaining a stable society will require careful planning. The crew will need to ensure that cultural evolution, language, and family structures remain intact. Dr. Cameron Smith, an anthropologist, has suggested that understanding how cultures evolve in isolated environments is crucial. According to Smith, “Evolution is at the heart of all life sciences, and it also, in many ways, applies to society. The society aboard a generation ship must adapt to the unique conditions of space travel, and evolve over time to ensure its survival” (Cameron Smith).

Maintaining Genetic Diversity

One significant concern will be maintaining genetic diversity. With only a limited number of humans onboard, the population could become genetically homogeneous, risking the emergence of genetic disorders. For this reason, it may be necessary to incorporate cryogenic sperm banks and embryo storage to ensure genetic diversity over generations.

The Competition: Project Hyperion’s Design Challenge

To solve these challenges, Project Hyperion has opened a competition for designers worldwide. The goal is to create the most effective design for a generation ship that can transport humans across space to another star system. The competition offers a total of $10,000 in prizes, with $5,000 for first place, $3,000 for second, and $2,000 for third.

Designers will need to take into account a variety of factors, including spacecraft size, population capacity, self-sustaining life support, artificial gravity, and interstellar propulsion. The best designs will demonstrate an innovative approach to the practical and theoretical challenges of interstellar travel.

If you are interested in the competition or have more questions, you should contact the Initiative for Interstellar Studies.

NASA’s Plans to Resume ISS Spacewalks in 2025

Since its inception, NASA’s International Space Station (ISS) program has been one of the most successful collaborative efforts in space exploration, involving agencies such as the European Space Agency (ESA) and Roscosmos. Spacewalks, also known as extravehicular activities (EVAs), are critical to ISS operations, allowing astronauts to conduct repairs, install equipment, and ensure the space station’s structural integrity.

Table 1: Historical Milestones of ISS Spacewalks

Year Milestone Description
1998 First ISS Spacewalk Conducted to prepare the first modules for assembly.
2013 Water Leak Incident Italian astronaut Luca Parmitano’s helmet filled with water, leading to a temporary suspension of EVAs.
2022 Coolant Leak Incident A helmet water leak led to a seven-month suspension of spacewalks.
2024 Recent Coolant Leak Suspension Spacewalks were suspended in June following a leak in astronaut Tracy Dyson’s suit.

The recent incident in June 2024 halted spacewalks indefinitely after NASA astronaut Tracy Dyson experienced a coolant leak in her spacesuit’s umbilical connector. Although Dyson and her partner, astronaut Mike Barratt, were not in immediate danger, the event emphasized NASA’s strict safety protocols. “We’ll look for the next opportunity… It’s not time-critical or urgent,” stated Dana Weigel, ISS program manager at NASA.

The June 2024 incident involved NASA’s long-used extravehicular mobility units (EMUs). These suits are vital for the station’s external operations, but the recent leak exposed vulnerabilities in their aging design. During a routine maintenance operation, a leak in Dyson’s suit led to the formation of ice particles. NASA responded swiftly, suspending spacewalks to thoroughly assess and resolve the issue.

“Safety is our top priority, and we took immediate steps to address any possible risks for our astronauts,” explained Bill Spetch, NASA’s ISS operations and integration manager.

Table 2: Components of the Extravehicular Mobility Unit (EMU)

With modifications made to the affected spacesuits, NASA has greenlit the tentative resumption of spacewalks for early 2025. Following the coolant leak, NASA addressed the issue by replacing the defective seal and repressurizing the suit to ensure its operational safety.

According to Spetch, “It’s just a matter of when is the right timing.” Spetch clarified that spacewalks will be strategically scheduled around other ISS activities, including crew arrivals and ongoing research experiments. NASA is also developing a new procedure checklist to ensure suit integrity before each EVA.

NASA’s Evolving Approach to Spacesuit Technology

NASA’s EMU suits, originally designed in the 1970s and adjusted over time, are based on designs from the Space Shuttle program. While reliable, the suits face limitations due to their sizing bias toward larger body types, reflecting the historical composition of the astronaut corps. This challenge, combined with recent leak incidents, has prompted NASA to seek newer spacesuit solutions through partnerships with private companies.

In 2023, NASA awarded contracts to firms like Collins Aerospace and Axiom Space to develop next-generation spacesuits. These partnerships are geared toward creating suits that are more adaptable, lightweight, and equipped with enhanced life support and mobility systems.

However, despite Collins Aerospace’s initial involvement, the company withdrew from its contract in 2024. “Their timeline would not support the space station’s schedule and NASA’s mission objectives,” stated a NASA spokesperson. NASA is evaluating alternatives to continue fulfilling ISS requirements while keeping pace with advanced designs suited for lunar missions under the Artemis program.

NASA’s push for spacesuit redesigns aligns with its ambitious plans, particularly under the Artemis program, aimed at establishing a sustained human presence on the Moon and beyond. Spacesuits suitable for lunar conditions will need to offer protection against fine lunar dust, extreme temperature shifts, and potential long-term wear.

Key Design Goals for Next-Gen Spacesuits

  1. Improved Mobility: Enhanced joint flexibility to facilitate movement on rugged terrains.
  2. Adaptability to Body Types: Suits designed to accommodate a wider range of astronaut body sizes.
  3. Lightweight Construction: Lighter materials to reduce energy consumption and improve ease of movement.
  4. Advanced Life Support: Redundant systems for oxygen supply, temperature control, and CO₂ removal.
  5. Modular Components: Interchangeable parts for repairs, reducing the need for new suits.

The Importance of Spacewalks for ISS Operations

Spacewalks remain indispensable to the ISS’s mission, enabling hands-on inspections and upgrades to hardware and infrastructure. Astronauts routinely inspect solar arrays, communications devices, and thermal control systems that require exposure to the harsh space environment. With the next spacewalk cycle approaching, NASA aims to resume maintenance tasks on crucial ISS components.

NASA is focused on making spacewalks safer and improving the technology used in them. This focus is part of its larger goals. The agency is planning to take on more challenging missions. Spacewalks are also known as EVAs (Extravehicular Activities), which are when astronauts leave their spacecraft to work in space. Earth’s orbit is becoming a busy place. It is important for scientific research and commercial businesses. Reliable and safe spacesuits are necessary. They will be crucial if people are going to live and work in orbit for a long time.

By investing in modern spacesuit technology, NASA is reinforcing its strategy to empower astronauts with advanced tools and equipment. These innovations hold promise not only for ISS operations but also for NASA’s ambitions for lunar and Martian exploration.

Main Article

In a surprising yet prudent move, NASA has decided to remove two astronauts from its forthcoming SpaceX Crew-9 mission. This decision, made to accommodate two astronauts originally scheduled to return to Earth on Boeing’s Starliner, This shows how space missions can be very dynamic and sometimes unpredictable. The Crew-9 mission will now continue with only two astronauts. These astronauts are Nick Hague from NASA and Aleksandr Gorbunov from Roscosmos, which is the Russian space agency.

Boeing’s Starliner, which has been undergoing a historic first test mission with astronauts, encountered significant issues with its propulsion system and thrusters. These problems raised concerns about the spacecraft’s ability to safely return astronauts to Earth. After two months of rigorous tests and safety discussions, NASA concluded that the risk associated with the Starliner’s thrusters was too high to allow for a crewed return.

Instead, NASA decided to bring the Starliner back to Earth uncrewed, scheduled for September 6, 2024. This decision necessitated a reassignment of astronauts Butch Wilmore and Suni Williams, who were to return on the Starliner. The safest and most logical solution was to include them in the Crew-9 mission, thus prompting the removal of two original Crew-9 astronauts, Zena Cardman and Stephanie Wilson.

With the changes, Crew-9 will now be a half-empty flight with only two crew members: Nick Hague and Aleksandr Gorbunov. Hague, who was originally the pilot of the mission, has been promoted to commander, while Gorbunov will remain as the mission specialist.

Nick Hague, a U.S. Space Force commander and former test pilot, has had an illustrious career in space exploration. He has already been to space twice as a NASA astronaut, although his first trip was cut short due to a rocket malfunction during a Soyuz launch in 2018. Despite this setback, Hague and his cosmonaut colleague Alexey Ovchinin safely returned to Earth, and both successfully completed a full ISS mission on their second attempt in 2019.

Aleksandr Gorbunov, on the other hand, will be making his first spaceflight on the Crew-9 mission. His seat is part of a NASA arrangement with Roscosmos, ensuring the continued presence of Russian astronauts on NASA missions, and vice versa. This collaboration is crucial for maintaining international relations and ensuring the success of joint space endeavors.

The decision to reassign astronauts has led to a delay in the Crew-9 launch, which is now scheduled for September 24, 2024. However, this date remains tentative due to complications arising from a separate incident involving SpaceX’s Falcon 9 rocket. The Falcon 9, which was set to launch the Crew Dragon spacecraft for the Crew-9 mission, is currently grounded following the loss of a different Falcon 9 variant during a Starlink satellite mission on August 28, 2024.

The incident has triggered an investigation by the Federal Aviation Administration (FAA), NASA, and SpaceX, adding another layer of uncertainty to the Crew-9 mission timeline. The outcome of this investigation will be critical in determining whether the new launch date can be met or if further delays are necessary.

The Boeing Starliner program has faced numerous challenges since its inception. Despite its initial promise as a competitor to SpaceX’s Crew Dragon, the Starliner has been plagued by technical issues and delays. The propulsion system problems encountered during this test mission are just the latest in a series of setbacks that have raised questions about the spacecraft’s reliability and safety.

However, it is important to recognize the significance of the Starliner program in the broader context of space exploration. Boeing’s efforts to develop a reliable and safe spacecraft for crewed missions are part of a larger push to expand humanity’s presence in space. The Starliner represents a critical component of NASA’s Commercial Crew Program, which aims to reduce dependence on Russian spacecraft and provide the United States with its own means of sending astronauts to space.

Despite the challenges, NASA and Boeing remain committed to the success of the Starliner program. The upcoming uncrewed return of the Starliner will provide valuable data that will be used to address the propulsion issues and improve the spacecraft’s performance in future missions.

The collaboration between SpaceX and NASA has been a cornerstone of recent advancements in space exploration. SpaceX’s Crew Dragon spacecraft has proven to be a reliable and safe vehicle for transporting astronauts to and from the International Space Station (ISS). The success of the Crew Dragon missions has allowed NASA to focus on other critical areas of space exploration, including the Artemis program, which aims to return humans to the Moon by the mid-2020s.

The recent challenges with Boeing’s Starliner and the Falcon 9 incident highlight the inherent risks and complexities of space exploration. However, they also underscore the resilience and adaptability of NASA and its commercial partners.

  • SpaceX is working closely with NASA to reconfigure the mission and ensure the astronauts’ safe return.
  • The decision reflects NASA’s confidence in SpaceX and the Crew Dragon’s reliability for human spaceflight.

The Reason SpaceX Crew Dragon Was Selected for Sunita Williams’ Return

Eighty days after launching from Cape Canaveral Space Force Station in Florida aboard Boeing’s Starliner mission, astronauts Sunita Williams and Butch Wilmore were scheduled to return to Earth. However, their return journey faced significant delays due to technical issues with the Starliner spacecraft. These problems, primarily helium leaks and thruster malfunctions, posed considerable risks, leading NASA to explore alternative solutions.

The Decision to Switch to SpaceX’s Crew Dragon

With safety as the top priority, NASA ultimately decided to switch from Boeing’s Starliner to SpaceX’s Crew Dragon for the astronauts’ return. This decision was influenced by several factors, including SpaceX’s proven track record in human spaceflight. Since 2020, Crew Dragon has successfully transported multiple crews to and from the International Space Station (ISS), earning a reputation for reliability and safety.

NASA Administrator Bill Nelson highlighted the agency’s extensive experience with spaceflight, both successful and unsuccessful, as a critical factor in their decision-making process. He stated, “Spaceflight is risky, even at its safest and even at its most routine. And a test flight, by nature, is neither safe, nor routine.” NASA’s careful consideration of past experiences, including the tragic loss of two space shuttles, underscored the importance of a robust safety culture where information can be shared openly and without hesitation.

Boeing’s Starliner program has faced numerous challenges over the years. Despite being a key player in NASA’s Commercial Crew Program, the spacecraft has struggled with technical issues that have delayed its progress. The latest setbacks, involving helium leaks and thruster problems, raised serious concerns about the Starliner’s readiness for a safe return mission.

  1. Helium Leaks: One of the critical issues with the Starliner was the helium leaks in its propulsion system. Helium is used to pressurize the fuel tanks, and any leakage can lead to a significant reduction in the spacecraft’s ability to maneuver safely.
  2. Thruster Malfunctions: In addition to the helium leaks, the Starliner experienced thruster malfunctions. Thrusters are essential for controlling the spacecraft’s orientation and performing maneuvers, especially during re-entry and landing. Any malfunction in this system could jeopardize the safety of the astronauts onboard.

Due to these unresolved issues, NASA deemed it too risky to bring Williams and Wilmore back to Earth using the Starliner. Instead, they opted for SpaceX’s Crew Dragon, a spacecraft with a proven safety record.

SpaceX’s Proven Track Record

SpaceX has been a key partner in NASA’s human spaceflight efforts since the early 2000s. The company’s Crew Dragon spacecraft has played a vital role in NASA’s Commercial Crew Program, successfully transporting astronauts to and from the ISS since 2020.

Crew Dragon first made headlines in 2020 when it completed its first crewed test flight, earning NASA’s certification for operational missions. Since then, SpaceX has conducted multiple crewed missions, demonstrating the spacecraft’s reliability and safety. Over the past four years, Crew Dragon has carried a dozen crews to and from the ISS, solidifying its position as a reliable workhorse for human spaceflight.

Gwynne Shotwell, SpaceX’s President and Chief Operating Officer, expressed the company’s commitment to ensuring the safe return of Williams and Wilmore. She stated, “SpaceX is ready to work with NASA to bring back astronauts Butch Wilmore and Suni Williams on the Crew Dragon spacecraft. We are fully committed to supporting NASA in any way necessary to ensure the success of this mission.”

Reconfiguring the Crew-9 Mission

The decision to use Crew Dragon for the return mission required significant adjustments to SpaceX’s upcoming Crew-9 mission. Originally scheduled as a routine mission to transport a four-person crew to the ISS, Crew-9 will now be reconfigured to accommodate Williams and Wilmore.

  1. Revised Crew Composition: To make room for the returning astronauts, SpaceX and NASA will need to revise the crew composition for the Crew-9 mission. This means selecting which astronauts will not fly to the ISS as initially planned and ensuring that the spacecraft can safely accommodate the additional passengers.
  2. New Spacesuits and Supplies: Along with the crew adjustments, new Dragon spacesuits for Williams and Wilmore will be sent to the ISS in the coming months. These suits are designed specifically for the Crew Dragon spacecraft and are essential for ensuring the astronauts’ safety during the return journey. Additionally, other necessary supplies will be sent to the ISS to prepare for the reconfigured mission.

NASA’s Focus on Safety

NASA’s decision to switch from Starliner to Crew Dragon underscores the agency’s unwavering commitment to safety in human spaceflight. The agency conducted a thorough review of its options, considering the risks associated with each spacecraft and drawing on its extensive experience with spaceflight.

NASA Administrator Bill Nelson emphasized the importance of a strong safety culture within the agency. He pointed out that NASA’s past failures, including the loss of two space shuttles, were partly due to a lack of open communication and a culture that did not prioritize safety above all else. “We lost two space shuttles as a result of there not being a culture in which information could come forward,” Nelson said.

SpaceX’s Collaboration with NASA

The successful collaboration between SpaceX and NASA has been a key factor in the success of the Commercial Crew Program. Since the early days of the partnership, both organizations have worked closely together to develop and certify the Crew Dragon spacecraft for human spaceflight.

  1. Joint Testing and Certification: The partnership between SpaceX and NASA has involved rigorous testing and certification processes to ensure the safety and reliability of the Crew Dragon spacecraft. These efforts have paid off, with Crew Dragon successfully completing multiple crewed missions without any major incidents.
  2. Continued Collaboration: As SpaceX prepares for the reconfigured Crew-9 mission, the company will continue to work closely with NASA to ensure that all safety protocols are followed and that the mission is a success. This collaboration includes ongoing communication between SpaceX’s engineers and NASA’s mission control teams, as well as joint decision-making on critical aspects of the mission.

While the decision to switch to Crew Dragon is a setback for Boeing’s Starliner program, it does not mark the end of the road for the spacecraft. NASA and Boeing remain committed to resolving the technical issues plaguing the Starliner and ensuring that it can be safely used for future missions.

Boeing has already begun work on addressing the helium leaks and thruster malfunctions that led to the recent delays. The company is also conducting a thorough review of the spacecraft’s systems to identify any other potential issues that could affect its performance.

  1. Empty Return Flight: To further assess the Starliner’s performance and safety, Boeing plans to fly the spacecraft back to Earth empty in early September. This uncrewed return flight will allow the company to test the spacecraft’s systems without risking the safety of any astronauts.
  2. Continued Development and Testing: Following the empty return flight, Boeing will continue to work on improving the Starliner, with a focus on addressing the issues identified during the recent mission. The company is committed to working with NASA to ensure that the Starliner meets all safety requirements and is ready for future crewed missions.

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

  • Axiom Space and Nokia are developing a 4G/LTE communication system for Artemis spacesuits.
  • The LSCS technology will offer high-speed communication for astronauts on the lunar surface.
  • 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:

  1. Network in a Box: This includes a base station, antennas, and other supporting systems installed on the Human Landing Services lander.
  2. 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.

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. This adaptability is crucial as NASA plans more complex missions, including establishing a permanent lunar base and eventually sending humans to Mars.

Axiom Space was founded in 2016 by Michael T. Suffredini and Kam Ghaffarian. Suffredini, previously the program manager for the International Space Station (ISS) from 2005 to 2015, brought extensive experience in space operations. Ghaffarian, an engineer and entrepreneur, sold his company, Stinger Ghaffarian Technologies, Inc., a major NASA contractor, to KBR in 2018. Together, they targeted the emerging commercial spaceflight market with the vision of building a privately funded space infrastructure.

In its early stages, Axiom Space focused on securing key partnerships and contracts. The company was selected by NASA to provide the first commercial destination module on the ISS, a significant milestone in its journey toward establishing a commercial space station.

NASA Contracts and Commercial Spaceflight

In 2020, Axiom Space was awarded a $140 million contract by NASA to provide at least one habitable spacecraft to attach to the ISS as part of the Next Space Technologies for Exploration Partnerships (NextSTEP) initiative. This contract underscored NASA’s confidence in Axiom’s capabilities and vision. Axiom’s modules are designed to attach to the Harmony forward port on the ISS, with plans to include a node module, a research and manufacturing facility, a crew habitat, and a “large-windowed” module for Earth viewing.

The company’s first commercial astronauts flew to the ISS in 2022 on Axiom Mission 1, marking a significant milestone in commercial spaceflight. This mission was operated by Axiom’s Mission Control Center in Houston and utilized SpaceX’s Falcon 9 rocket and Crew Dragon spacecraft. The mission demonstrated Axiom’s ability to plan, manage, and execute crewed spaceflights.

Axiom Station

Axiom Space’s ultimate goal is to build and operate the world’s first commercial space station, known as Axiom Station. The company plans to launch its modules individually and assemble them in orbit, initially attaching them to the ISS. Before the ISS is retired and reenters Earth’s atmosphere, Axiom plans to detach its modules and operate independently as Axiom Station.

Design and Features

The interior of Axiom Station, designed by French architect Philippe Starck, features walls covered with tufted padding and studded with hundreds of color-changing LEDs, creating a futuristic and comfortable environment. The station will include amenities such as high-speed Wi-Fi, video screens, picture windows, and a glass-walled cupola for stunning views of Earth.

Axiom Space intends to maintain at least one astronaut continuously aboard the station to manage research projects and station repairs. The company’s renderings show how modules might be berthed and relocated on the ISS by the Mobile Servicing System, specifically the Canadarm2, which could continue its operations on Axiom Station after the ISS’s retirement.

Launch Timeline

The first module of Axiom Station is targeted for launch in late 2026, with the station expected to be completed by the late 2020s. Up to three Axiom Space modules could attach to the ISS, with the first docking to the forward port of Harmony. The company plans to send private astronauts to these modules for various missions.

The launch clock isn’t set yet, but the hardware is lined up for what would become the most powerful rocket to ever send humans into space during a moonbound trip the likes of which has not happened in more than 50 years. The biggest piece of the Space Launch System rocket, the 212-foot-long core stage, crept its way into the massive Vehicle Assembly Building on July 24, where work will begin to prepare it for the Artemis II launch set for no earlier than September 2025.

“The clock’s already started,” said John Honeycutt, NASA SLS program manager. “We’ve got a great deal of work to do to get the rocket ready to go fly.”

The core stage sports four RS-25 engines converted by Melbourne-based L3Harris’ Aerojet Rocketdyne from the retired stock of the Space Shuttle Program. Two of the engines have previously flown on a combined 20 shuttle missions, while the other pair are making their debuts. Engine 2047 flew on STS-135, the final launch of the program on Space Shuttle Atlantis in 2011.

Also no stranger to KSC are the casings from the two solid rocket boosters fabricated by Northrop Grumman. They had previously supported space shuttle missions but were regularly fished out of the ocean for refurbishment. Those two boosters sit broken down into five segments each just north of the VAB at the Rotation, Processing, and Surge Facility.

Combined, the core stage and the boosters provide 8.8 million pounds of thrust on liftoff. Their next launch will make the SLS the most powerful rocket to ever send humans into space. NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch with Canadian astronaut Jeremy Hansen will ride in the Lockheed Martin-built Orion capsule for what’s planned to be a 10-day trip around the moon.

Doug Hurley, a former NASA astronaut and now an executive with Northrop Grumman who flew on both shuttle missions and the first human spaceflight of SpaceX Crew Dragon, has tried to give the astronauts an idea of what their ride might be like.

“The ride on the booster for 126 seconds, I just said it’s gonna be the most incredible ride of your life. Because really, the acceleration is eye-watering,” Hurley said.

The shuttle rides used boosters made up of four segments versus the five that are stacked for SLS, and with Orion on top of the core stage, it will be more like the Apollo astronauts’ rides on the Saturn V rocket.

“Being on the top of the stack and feeling the steering … can’t wait to hear the story,” he said.

Their goal is to ensure the Orion capsule’s life-support systems work, setting up the Artemis III mission no earlier than September 2026. That mission aims to return humans, including the first woman, to the lunar surface for the first time since the Apollo 17 mission in 1972.

The Artemis II quartet, though, will still travel more than 230,000 miles from Earth, and while not landing on the moon, flying beyond low-Earth orbit is a feat that also has not been accomplished by humans since the final Apollo flight. Glover will become the first Black man to make the trip, Koch the first woman, and Hansen the first Canadian. All 24 of the astronauts who made the trip during nine Apollo missions to the moon between 1968 and 1972 were white American men. Six of those missions sent 12 of those men to the lunar surface.

Delays and Uncertainty

The 2025 launch date for Artemis’ first human spaceflight is nearly a year behind the schedule laid out after the successful launch of Artemis I in November 2022. A roughly two-year gap between the uncrewed debut and the first crewed mission was thought to be enough time to pore over the Artemis I data and work through any issues. But a series of major bumps in the road became evident and one of them has yet to have a final solution revealed by NASA.

That’s the fact that the protective coating on Orion’s heat shield lost a lot more material, some in fist-sized chunks, than what was expected. The ultimate solution for the Orion capsule will be the major domino holding up the process of stacking the SLS to get ready for launch. Managers won’t begin putting it together vertically until they know there will be a spacecraft coming to top it off, but even though this is the second time around, NASA managers expect to face some hurdles.

“There’s always something that happens, you know, something spills on something, some test didn’t work as planned,” said Chris Cianciola, the SLS deputy program manager. “So you triage it all the way. You don’t want to wait ’til you get out to the launch pad to find out you got a problem.”

For now, a completed Orion capsule is expected to be delivered to the VAB by Oct. 31. If NASA signals no delay, then the first placement of the solid rocket boosters in the VAB could begin in September. NASA has built in a one-year lifespan limiter for the solid rocket boosters, a clock that starts ticking the moment the second segment is placed atop the first. That’s expected to happen in the late fall, which would keep Artemis II on its launch target timeline.

Another limiting factor in stacking is getting back to the VAB the mobile launcher on which SLS and Orion will sit. Currently parked at KSC’s Launch Pad 39-B, it has had to go through a series of repairs after the Artemis I launch tore parts of it to shreds.

“These are the largest solid rocket motors on the planet, and when that vehicle lifts off from the mobile launcher, that plume has to go someplace,” said Shawn Quinn, program manager for Exploration Ground Systems (EGS) based at KSC. “As the vehicle gets higher up, that plume spreads out, and it’s a very, very strong force. … Forget about the heat for a moment, but if the person was standing there, they’d be blown out to kingdom come.”

EGS crews also have had to install emergency exit apparatus such as the zipline cages and crew access arm changes so the humans on board can have a chance to survive if something goes wrong on the pad. Quinn said that work is “nearly done” and the mobile launcher should be back at the VAB in time for stacking.

Cost and Criticism

The Artemis program now controls the majority of NASA’s annual budget this year, surpassing the overall science mission budget for the first time as the agency’s top-funded segment. The enacted fiscal 2024 budget comes out to more than $7.6 billion of NASA’s overall $24.875 billion budget. Because the Artemis program involves so many commercial partners, it has a lot of support across Congress, which ultimately approves the budget. So while the science budget request was cut by more than $500 million from the Biden administration request this fiscal year, the Artemis campaign programs were nearly fully funded.

NASA’s Office of the Inspector General has continued to audit the growing costs of the Artemis program, with a 2023 report stating that the Artemis III missions will cost the country $93 billion since its inception in 2012. That’s billions more than envisioned with delays and cost increases plaguing the leadup to Artemis I. The SLS rocket represents 26% of that cost to the tune of $23.8 billion, with a giant chunk spent on the first and second launch hardware.

The audit forecasts future SLS launches to cost more than $2.5 billion each, although NASA has laid out a plan to reduce those costs by half, something the OIG deemed “highly unrealistic” and a threat to its deep-space exploration plans. The audit, though, notes that while SLS is the only viable option now for NASA, competition from SpaceX Starship and Blue Origin’s New Glenn rockets may help level the playing field for NASA’s plans.

“Although the SLS is the only launch vehicle capable of transporting both crew and cargo to the moon in a single mission, its high cost threatens the affordability and sustainability of NASA’s Artemis missions,” the audit stated. “The Agency has taken steps to lower production costs by requiring future SLS rockets to be produced with new, non-refurbished RS-25 engines and solid rocket booster segments. NASA also seeks to reduce per-mission costs to $1.5 billion or less, a goal we find highly unrealistic based on current costs.”

In its response, NASA said it would be up to private companies such as SpaceX and Blue Origin to take up the challenge to provide the vehicles for the next missions to deep space with a target of 2040 for humans to land on Mars. Even for now, a version of Starship is slated to provide the human lunar lander for the Artemis III mission.

But for now, the focus is on getting SLS ready for humans to make the trip around the moon and back. Honeycutt said that while there were still a lot of milestones to hit before launch, he expects to be able to meet them.

“We got to stay focused,” he said. “We don’t have the budget to start over. We got to press forward with what we got and make it work.”

In January 2031, a specially designed spacecraft by SpaceX, known as the U.S. Deorbit Vehicle, will undertake the critical task of de-orbiting the ISS. On July 17th, NASA held a live press conference to unveil the details of this mission, including a first look at the modified SpaceX Dragon capsule responsible for the deorbit process.

Unveiling the U.S. Deorbit Vehicle

During the press conference, NASA revealed several key features of the U.S. Deorbit Vehicle. SpaceX shared details and an image of the special Dragon via their official X account (formerly Twitter). According to SpaceX, the modified spacecraft will have six times the propellant and four times the power of today’s Dragon spacecraft. The image released shows a robust service module replacing the trunk used by the standard Crew Dragon vehicle. This new service module is larger and equipped with additional fold-out solar arrays, as well as hull-mounted solar panels, to provide the necessary power for the mission.

The modified Dragon capsule also appears to have more Draco engines than the standard Crew Dragon vehicle. The standard Crew Dragon is equipped with 18 Draco engines, each capable of generating 400 Newtons (90 lbf) of thrust, totaling 7,200 N (360 lbf) of thrust. The U.S. Deorbit Vehicle is expected to have 72 Draco thrusters arranged concentrically, capable of generating close to 30,000 Newtons (1,440 lbf) of thrust. This significant increase in thrust power is crucial for the controlled deorbit of the massive ISS structure. The image also shows the spacecraft docking with the Kibo module operated by the Japan Aerospace Exploration Agency (JAXA).

Contract and Development

NASA announced the selection of SpaceX in late June to develop the U.S. Deorbit Vehicle as part of a single-award contract valued at up to $843 million. While SpaceX is responsible for the development of the spacecraft, NASA will take ownership once it is complete and operate it throughout the mission. The spacecraft, along with the ISS, is expected to break up during re-entry, with the remains landing in the “spacecraft cemetery” in the South Pacific. The contract for the launch services has not yet been awarded but is expected to be announced shortly.

SpaceX’s Broader Role in Space Exploration

In addition to the U.S. Deorbit Vehicle, SpaceX is heavily involved in other significant NASA missions. SpaceX is developing the Human Landing System (HLS), specifically the Starship HLS, which will transport astronauts to the lunar surface as part of the Artemis III and IV missions. Furthermore, SpaceX has been contracted to launch the core elements of the Lunar Gateway—the Power and Propulsion Element (PPE) and the Habitation and Logistics Outpost (HALO)—into lunar orbit using a Falcon Heavy rocket in November 2025.

The ISS: A Platform for Scientific Advancement

Since its launch in 1998, the ISS has served as a unique platform for scientific research and technological demonstrations that are not possible on Earth. The ISS is a collaborative effort involving five space agencies: NASA, the Canadian Space Agency (CSA), the European Space Agency (ESA), JAXA, and the Russian State Space Corporation (Roscosmos). Throughout its operational lifetime, the ISS has hosted a wide range of experiments, including studies on the effects of microgravity and space radiation on human, animal, and plant physiology. This research is crucial as NASA and its international partners plan for long-duration missions to the Moon and Mars in the coming decades.

A Symbol of International Cooperation

Beyond its scientific contributions, the ISS stands as a symbol of international cooperation and peaceful use of outer space, in line with the Outer Space Treaty and its core philosophy that “space is for all.” NASA, CSA, ESA, and JAXA have all committed to operating the ISS through 2030, while Roscosmos has committed to continue operations until at least 2028. The safe deorbit of the ISS is a shared responsibility among all five space agencies, ensuring a controlled re-entry and disposal process.

Enhanced Capabilities of the U.S. Deorbit Vehicle

The U.S. Deorbit Vehicle is a big improvement over the current Dragon spacecraft. It has six times more fuel and four times more power. This modified spacecraft can de-orbit the ISS. De-orbiting means guiding the space station back into the Earth’s atmosphere.

The vehicle has a strong service module. A service module is the part of the spacecraft that holds the main systems, like power and propulsion. It also has more solar panels to collect energy from the sun. Additionally, it comes with more Draco engines. Draco engines help the spacecraft move in space. All these upgrades are important. They help the spacecraft do its job well.

The service module is particularly noteworthy. Unlike the standard Crew Dragon vehicle, which uses a trunk for storage and supports various mission operations, the U.S. Deorbit Vehicle’s service module is larger and more powerful. The additional fold-out solar arrays and hull-mounted solar panels ensure that the spacecraft has the necessary power to sustain its systems and perform the de-orbit burn.
