Axiom Space tacked on an additional $175 million to a previously announced capital raise, bringing the oversubscribed round to a total of more than $525 million.

Axiom shared in February that it had secured $350 million in a financing round led by Type One Ventures and Qatar Investment Authority. In the latest release from the company, Axiom reports that Japan-based MUFG Bank Ltd. joined the round as a new investor, in addition to continued participation from existing backers.

The funding will go toward developing the company's commercial space station, known as Axiom Station, and the production of its Axiom Extravehicular Mobility Unit (AxEMU) under its NASA spacesuit contract.

“Investor interest in this round outpaced what we set out to raise, which speaks to the moment we’re in,” Jonathan Cirtain, CEO and president of Axiom Space, said in the news release. “Our partners see what is possible in low-Earth orbit, and they see who is positioned to lead it.”

Axiom announced last month that it planned to open a Japanese subsidiary July 1. Earlier this week, it also shared plans to establish Axiom Space Switzerland, a wholly owned subsidiary based in Lucerne that is also expected to begin operations this summer.

The Switzerland subsidiary aims to establish Axiom's presence in Europe and help it partner with the European Space Agency and other space organizations and companies on the continent.

“Europe is a founding leader in the creation of the commercial space economy, and Switzerland is uniquely positioned to convene the government agencies, research institutions, and industrial entities that will shape its next decade,” Cirtain added in a separate release. “Axiom Space Switzerland facilitates the scaling of development and deployment of the infrastructure that will succeed the International Space Station.”

Houston-based Axiom Space and Nokia are partnering to incorporate high-speed cellular-network capabilities in Axiom's technology.

Nokia will integrate advanced 4G/LTE communication capabilities in the Axiom Extravehicular Mobility Unit, or AxEMU, spacesuit supporting HD video, telemetry data, and voice transmission that can span over multiple kilometers on the moon. The advancement will enable Artemis III crew members to capture video and communicate with mission controllers on Earth in real-time while on the moon.

Nokia will deploy the first cellular network on the moon as part of Houston-based Intuitive Machines’ IM-2 mission. The mission is scheduled to be delivered to the launch site before the end of the year. Nokia will attempt to show how cellular connectivity can facilitate communications during lunar or Mars missions in the future. Nokia’s Lunar Surface Communications System (LSCS) is pioneered by Nokia Bell Labs’ research and innovation. It will be deployed during IM-2 and will be adapted for use in the AxEMU spacesuit.

“Just as astronauts will need life support, shelter and food, they will need advanced networks to communicate with each other and go about their crucial work,” Thierry E. Klein, president of Bell Labs Solutions Research at Nokia, says in a news release. “Bell Labs has a long history of working on space projects, and Nokia is a leader in designing and building networks that connect the world. We are taking advantage of the same standards-based technologies that connect billions of devices on Earth every day, while bringing new innovation and technologies to bear on the specific challenges encountered in space."

Axiom Space was awarded $57.5 million from NASA to make the 4G/LTE network modification to the lunar spacesuit for the Artemis III mission, which builds upon its first Artemis task order in 2022 that is valued at $228 million. Axiom Space’s spacesuits provide astronauts with capabilities for space exploration while providing NASA with commercially developed human systems necessary for life and communications on the moon.

“Axiom Space is excited to work with Nokia to build on the advanced capabilities of our next-generation spacesuit,” Russell Ralston, Axiom Space executive vice president of extravehicular activity, adds. “Adding high-speed 4G/LTE network capability on the Moon will serve as a vital bridge linking astronauts to Earth, facilitating crucial data exchange, and enabling high-definition video communication over long distances.”

Houston space tech company secures third NASA mission, reveals new spacesuits

ready for liftoff

A Houston-based space tech company has revealed details on two of its commercial partnerships with NASA.

NASA and Axiom Space have again signed a mission order for a private astronaut mission to the International Space Station. The mission will commence sometime in November or on and will be from the agency’s NASA’s Kennedy Space Center in Florida. Axiom Mission 3 is the third mission of its kind and, according to a statement from NASA, is expected to be a 14-day trip.

The ISS's Multilateral Crew Operations Panel will approve four proposed crew members and two back up crew submitted by Axiom for the Ax-3 mission. The crew will be expected to train for their flight with NASA, international partners, and SpaceX beginning this spring, according to NASA.

“Axiom Space’s selection to lead the next private astronaut mission to the International Space Station enables us to continue expanding access to nations, academia, commercial entities, and emerging industries to research, test, and demonstrate new technologies in microgravity,” says Michael Suffredini, CEO and president of Axiom Space, in the release. “As NASA’s focus shifts back to the Moon and on to Mars, we are committed to transforming low-Earth orbit into a global space marketplace, where access to space moves beyond the partners of the space station to nations, institutions and individuals with new ideas fueling a thriving human economy beyond Earth.”

Axiom's historic first commercial launch was in spring of 2022, and Ax-2, which will launch the first Saudi astronauts to visit the ISS, is expected to launch this spring. In addition to these two missions, Axiom has been tasked by NASA to develop spacesuits and space station technology.

After several months of working on the suits, Axiom has revealed the details of the technology that will be worn by NASA astronauts returning to the moon on the Artemis III mission that's scheduled to land near the lunar south pole in 2025.

“We’re carrying on NASA’s legacy by designing an advanced spacesuit that will allow astronauts to operate safely and effectively on the Moon,” says Suffredini in a statement from the company. “Axiom Space’s Artemis III spacesuit will be ready to meet the complex challenges of the lunar south pole and help grow our understanding of the Moon in order to enable a long-term presence there.”

Called the Axiom Extravehicular Mobility Unit, or AxEMU, the prototype was revealed at Space Center Houston’s Moon 2 Mars Festival today, March 15. According to Axiom, a full fleet of training spacesuits will be delivered to NASA by late this summer.

At the same time as the Ax-3 mission announcement, NASA also announced that it has selected Firefly Aerospace of Cedar Park, Texas, to carry multiple payloads to the far side of the Moon. According to NASA, the commercial lander will deliver two agency payloads, as well as communication and data relay satellite for lunar orbit, which is an European Space Agency collaboration with NASA.

The contract — awarded for around $112 million — is targeted to launch in 2026 through NASA’s Commercial Lunar Payload Services, or CLPS, initiative, and part of the agency’s Artemis program. It's the second award to Firefly under the CLPS initiative.

“The diversity of currently available commercial orbital human spaceflight opportunities is truly astounding. NASA’s commercial crew flights to the space station for our government astronauts paved the way for fully private missions to space like Inspiration4 and Polaris as well as private astronaut missions to the orbiting laboratory like the one we are announcing today,” says Phil McAlister, director of commercial space at NASA Headquarters in Washington, in the release. “We are starting to see the incorporation of space into our economic sphere, and it is going to revolutionize the way people see, use, and experience space.”

Houston brain health co. secures $6.5M for rare disease study

neuro funding

Houston-based Goldenrod Therapeutics, part of Fannin Partners' portfolio, has announced the initial close of a $6.5 million series seed preferred stock round.

The round was led by Ataxia Ventures and an affiliate of Fannin, according to a news release.

Goldenrod Therapeutics plans to use the funding to support manufacturing, formulation optimization, IND-enabling studies and a Phase I study of its drug to treat brain inflammation, known as 11h.

The study will consider how 11h, which blocks the enzyme PDE4, could treat Friedreich’s ataxia (FA), a rare genetic disease that affects movement, speech and balance. To date, other PDE4 inhibitors have proven to regulate neuroinflammation and neuronal signaling, but have had adverse gastrointestinal side effects or have not reached enough of the central nervous system, according to Goldenrod.

The company says its 11h is expected to have "broad applicability" with limited emetric side effects.

“Our 11h program is a next-generation, orally bioavailable, brain-penetrant PDE4 inhibitor, where researchers overcame longstanding limitations associated with earlier PDE4 inhibitors," Dr. Dev Chatterjee, CEO of Goldenrod, said in the news release. "We believe this creates the potential for a best-in-class therapy for Friedreich’s Ataxia and a potential foundation for development across multiple neurodegenerative and neuroinflammatory disorders.”

11h was first developed at the University of Nebraska Medical Center (UNeMed). Houston-based Fannin Partners in-licensed the product 2020 and landed SBIR Phase I funding to support its initial development for opioid use disorder soon after.

Goldenrod has also received funding to study 11h's effectiveness for multiple sclerosis, methamphetamine addiction and cocaine addiction.

Goldenrod says it is developing 11h to target a variety of neurological and inflammatory conditions, including Alzheimer's disease, multiple sclerosis, ALS, substance use disorders, Batten disease, pain and traumatic brain injury.
