Axiom Space launches semiconductor and astronaut training initiatives

space projects

Axiom Space, a Houston-based commercial spaceflight and space infrastructure company, has launched initiatives in two very different spheres — semiconductors and astronaut training.

On the semiconductor front, Axiom has signed a memorandum of understanding with Japanese chemical company Resonac Corp. to collaborate on semiconductor R&D and manufacturing projects carried out in space. Among Resonac’s products are materials used in chip manufacturing.

Axiom said the deal “paves the way toward leveraging microgravity to advance next-generation chip technologies and accelerate the in-space manufacturing market.”

Under the agreement, Axiom and Resonac will explore the potential production of semiconductor materials and chip packaging in microgravity and low-Earth-orbit environments.

“The unique environment of space offers immense potential for advancing semiconductor materials, especially in crystal growth,” Masato Fukushima, Resonac’s chief technology officer, said in a news release.

The deal will also extend Resonac’s work with Axiom on the development of molding compounds that can reduce “soft errors” when semiconductor devices are exposed to space radiation.

“Our collaboration with Resonac underscores how Axiom Space is enabling global corporations from around the world to leverage space to drive manufacturing innovation across critical technology sectors such as semiconductors,” Axiom astronaut Koichi Wakata, the company’s chief technology officer, said.

In the astronaut training arena, Axiom has tapped Portuguese physiologist Emiliano Ventura as its first “Project Astronaut.” Ventura will apply his expertise in human performance to a pilot program aimed at testing six-month astronaut training protocols.

“His goal is to participate in a future mission and explore, with scientific depth and curiosity, how the human body adapts to microgravity, contributing fresh insights to the current body of research in space physiology,” Axiom said.

Ventura has helped several Axiom crewmembers with physiological needs before and after missions aboard the International Space Station.

Axiom said Ventura’s pilot program will study astronauts’ physiological responses to microgravity during spaceflight. The program eventually will benefit Axiom astronauts heading to the world’s first commercial space station, which is being built by Axiom.

Michael López-Alegria, Axiom’s chief astronaut, said he and the company’s two other astronauts will train with Ventura. The Project Astronaut initiative “strengthens our commitment to enabling safe, effective, and inspiring commercial space missions while supporting scientific objectives worldwide.” López-Alegria said.

Houston scientist launches new app to support mental health professionals

App for that

One Houston-based mental health scientist is launching a new app-based approach to continuing education that she hopes will change the way doctors, therapists, and social workers evolve in their field.

The app, MHNTI, is named for its parent company, the Mental Health Network & Training Institute. It's a one-stop shop for mental health professionals to find trainers, expert consultations, local providers, webinars, and other tools related to licensure certification and renewal.

Free and paid tiers offer different levels of access, but both offer doctors, counselors, and more an easier way to engage with continuing education. When a mental health professional is looking to expand their knowledge in a way that coincides with CE requirements, MHNTI provides it; as easy as using Amazon.

"We built MHNTI for the clinicians craving meaningful, ongoing training that fits real-life schedules," said Dr. Elizabeth McIngvale. "MHNTI is more than an app. It's a movement to support mental health professionals at every career stage."

McIngvale, the daughter of celebrated Houston entrepreneur Jim "Mattress Mack" McIngvale, co-founded MHNTI after becoming one of the leading experts on obsessive-compulsive disorder (OCD) in the United States. Born with the condition herself, she suffered greatly as a child to the point that she required extensive repetitive rituals daily just to function. She responded to exposure with response prevention (ERP) treatment, earned her Ph.D. from the University of Houston, and is now the director at the OCD Institute of Texas.

This is not the first time she used the internet to try to improve the mental health industry. In 2018, she launched the OCD Challenge website, a free resource for people with OCD.

McIngvale's co-founder is New York-based doctor, entrepreneur, and author Lauren Wadsworth, another expert in OCD and other anxiety disorders. Like McIngvale, she understands that the labyrinthian world of continuing education can keep mental health professionals from achieving their potential.

"Mental health providers are often overworked and under-resourced. MHNTI is here to change that," said Wadsworth. "We're creating a space where clinicians can continuously learn, grow, and feel supported by experts who understand the work firsthand."

MHNTI is available in the App Store, Google Play, and for desktop.
