What is the Key to Sustainability in the Final Frontier?

On the Space to Grow podcast, Astroscale's Chris Blackerby and Charity Weeden discuss the technology, international policy, and scalability required for sustainable space exploration. They draw on experience spanning civil, commercial, and defense sectors to address the next generation of space sustainability challenges, including orbital debris and responsible use of space.

Key takeaways

01

Sustainability in space requires coordination across civil, commercial, and defense sectors.

02

International policy frameworks are critical to governing debris removal and orbital resource management.

03

Scalable technology solutions are essential for the long-term viability of space operations.

On the Space to Grow podcast, Astroscale’s Chris Blackerby and Charity Weeden bring their compelling experience and expertise to map out the technology, international policy, and scalability that will define the next generation of space exploration.

There are three distinct areas of space exploration—civil, commercial, and defense. It’s rare to find a leader that has contributed to all three. Space to Grow welcomed such a pioneer, Pamela Melroy. Melroy spoke with hosts Chris Blackerby and Charity Weeden about her career and the importance of all three aspects cooperating.

Melroy has an impressive career. She was an astronaut, flying three times, and was commander of one of those missions. She held other positions at NASA, the FAA, DARPA, and Lockheed Martin. Now she’s the Director of Space Technology and Policy for Nova Systems, an engineering and technology solutions partner.

Melroy described her career path. “I wanted to be an astronaut and didn’t outgrow it. I had a singular focus on it.

“Sustainability is a national problem, and cooperation essential. The International Space Station represents this. It requires trust to go forward.” – Pam Melroy

Then it was time to stop flying, and I wanted to keep working on important things and another mountain to climb.” It became mountains as she traversed through all aspects of the space world, learning and adapting along the way.

Her experience taught her that the three areas of space were in deep silos. Each has different agendas, motivations, and priorities. Those don’t always align, even for many fundamental areas. She noted the example of servicing satellites. “NASA knows all about it, and I did it in space. However, there’s a fundamentally different approach to the problem.”

Additionally, there is the complex problem of space debris removal, requiring international collaboration, but it’s not happening. Melroy said, “It’s easy to point the finger at the policy issue as holding us back. Sustainability is a national problem, and cooperation essential. The International Space Station represents this. It requires trust to go forward.”

Quotient Sciences launches Phase I study of what it calls the first AI-formulated drug in the clinic

Quotient Sciences launches Phase I study of what it calls the first AI-formulated drug in the clinic

Quotient Sciences has initiated a Phase I clinical study at its UK facility for an oral solid dose formulation designed using artificial intelligence — what the company believes is the first AI-formulated drug to reach human clinical evaluation. The study, cleared by the UK's Medicines and Healthcare products Regulatory Agency, will assess safety and pharmacokinetics in healthy volunteers. The program, which used Intrepid Labs' machine learning algorithm, signals a broader shift in how contract drug development organizations are integrating AI across formulation and clinical workflows.

  • 01Quotient Sciences initiated a Phase I study of an AI-designed oral solid dose formulation at its UK facility following MHRA approval — the first such case the company believes has been reported.
  • 02The formulation was developed using Intrepid Labs' advanced machine learning algorithm in combination with Quotient Sciences' Translational Pharmaceutics platform.
  • 03The milestone is part of a broader CRDMO strategy to embed AI-enabled approaches across formulation development and clinical workflows, with implications for the wider contract pharma sector.

Quotient Sciences launches Phase I trial of what it calls the first AI-formulated drug to reach the clinic

Quotient Sciences has initiated a Phase I clinical study of an oral solid dose formulation designed using AI, cleared by the UK's MHRA and conducted at the company's UK facility. The trial—built on machine learning algorithms from partner Intrepid Labs and Quotient's Translational Pharmaceutics platform—aims to validate AI as a direct contributor to formulation design rather than just an upstream analytical tool. Benchling characterizes the broader moment as biotech entering a "builder phase," in which leading organizations embed AI capability at the bench level rather than running isolated pilots.

  • 01Quotient Sciences has dosed healthy volunteers in a Phase I study it describes as the first clinical evaluation of an AI-designed oral formulation, following approval from the UK's MHRA.
  • 02The formulation was developed using advanced machine learning algorithms from Intrepid Labs, integrated with Quotient Sciences' Translational Pharmaceutics platform.
  • 03Benchling identifies a sector-wide shift toward embedding AI capability directly at the bench, moving beyond isolated pilots to structural adoption across biotech R&D.
