The Future of Cryogenic Fuel Storage
Another significant aspect of the CRS-34 Dragon's return is the hardware and data it carries, including drives containing fluid-physics data. This data could help validate models and contribute to the design of more efficient cryogenic fuel storage systems for long-duration missions. Many spacecraft use cryogenic fuels for propulsion, but temperature swings in space can cause these extremely cold fuels to slowly evaporate and escape their tank, reducing fuel efficiency and complicating mission planning.
What makes this experiment particularly intriguing is the potential for space-based research to inform the design of more efficient and sustainable cryogenic fuel storage systems. By understanding how gases that do not condense into liquids at cold temperatures affect pressure control and fluid behaviors in propellant tanks, we could develop new technologies that could revolutionize space exploration and make long-duration missions more feasible and sustainable.
The Promise of Semiconductor Research
The CRS-34 Dragon also carries samples from NASA's In-Space Production of Semimetal-Semiconductor Composite Bulk Crystals in Microgravity (SUBSA-InSPA-SSCug) investigation. This study manufactured semimetal-semiconductor composite alloy crystals in space, which have applications in many electronics, including sensors and lasers. Researchers believe microgravity could enable the production of significantly greater and higher-quality crystals, supporting the development of next-generation semiconductor technologies.
