Tech Briefs - July 2024 - Vol. 48 No. 7

Overview

The July 2024 issue of Tech Briefs, titled "Beyond Earth: The Rise of Space Factories," delves into the transformative advancements in space manufacturing and the burgeoning in-space economy. This special edition highlights the shift from theoretical concepts to practical applications in space, showcasing how manufacturing and servicing facilities are evolving from science fiction into reality.

Key Themes and Innovations:

1. In-Space Manufacturing and Servicing: The issue emphasizes the growing importance of in-space servicing, assembly, and manufacturing (ISAM). As commercial space companies develop technologies for transport, communication, life extension, and situational awareness, ISAM is poised to become a core component of the future space economy. This evolution is driven by the need for sustainable practices in space, particularly as the population of objects in low Earth orbit increases.

2. 3D Printing and Flexible Devices: A notable feature in this issue is the exploration of 3D printing technologies, particularly the development of flexible devices without mechanical joints. Researchers at EPFL have created a prototype "finger" using 3D-printable double network granular elastomers, demonstrating the potential for manufacturing supple devices that can bend and stretch. This innovation could have significant implications for robotics and other applications requiring flexible components.

3. Space Sustainability: The issue also addresses the critical topic of space sustainability, focusing on the need to track and manage space debris to prevent collisions and ensure the safety of the space environment. A quiz included in the magazine tests readers' knowledge about space sustainability, highlighting the growing awareness and importance of this issue in the aerospace community.

4. Future of Military Vehicles: An interview with Rick Kewley, Vice President of Product Development and Advanced Engineering at GM Defense LLC, discusses the future of hybrid and electric military vehicles. This segment explores the latest research and development efforts aimed at creating more efficient and sustainable military transportation options, reflecting broader trends in the automotive and defense industries.

5. Technological Advancements: The magazine features various technological advancements in measurement, control, and monitoring tools. It highlights products from leading brands such as ifm efector and AutomationDirect, showcasing innovations like barcode scanners and vision systems that enhance operational efficiency in manufacturing and other sectors.

6. Commercial Space Ventures: The issue provides insights into several commercial space ventures that are pioneering new technologies and business models. These companies are not only focusing on manufacturing in space but also on creating a sustainable ecosystem that supports long-term human presence and activity beyond Earth.

7. Challenges and Opportunities: While the advancements in space manufacturing present numerous opportunities, the issue also addresses the challenges that come with them. These include technical hurdles, regulatory considerations, and the need for international cooperation to ensure the responsible use of space resources.

8. Future Prospects: Looking ahead, the magazine speculates on the future of space factories and the potential for large-scale manufacturing operations in orbit. As technology continues to advance, the possibility of producing everything from satellites to components for deep space missions becomes increasingly feasible.

In summary, the July 2024 issue of Tech Briefs provides a comprehensive overview of the current state and future prospects of space manufacturing. It highlights the intersection of technology, sustainability, and innovation, offering readers a glimpse into a future where space factories play a crucial role in the economy and exploration of outer space.
