In the quest for lunar and Martian exploration, NASA faces a critical obstacle: limited access to vital data from companies engaged in developing key capabilities for space travel. At the forefront of this challenge lies the development of cryogenic fluid management
technologies, integral for storing and transferring propellants like liquid hydrogen and liquid oxygen in space. This capability is essential not only for lunar landers under development by companies like Blue Origin and SpaceX for NASA's Human Landing System (HLS) program but also for future propulsion systems, including nuclear thermal propulsion.
John Dankanich, NASA's in-space transportation system capability lead, shed light on this issue during a presentation at a recent meeting of the National Academies' Committee on NASA Mission Critical Workforce, Infrastructure, and Technology. Dankanich highlighted that while multiple companies are actively working on cryogenic fluid management technologies funded by NASA, the agency faces hurdles in accessing crucial data necessary for understanding the performance and integration of these technologies with other systems.
The challenge arises from the contractual mechanisms employed in these collaborations. Dankanich explained that data access restrictions within these agreements inhibit NASA's ability to gather telemetry and essential data for model validation, hampering efforts to improve understanding and share insights with the broader scientific community. Even when data is accessible, restrictions on data rights often prevent NASA from distributing it for broader use in model validation.
This issue is particularly pronounced in contracts related to the HLS program, where cryogenic fluid management is viewed as a means to an end—transporting astronauts to and from the lunar surface—rather than a standalone focus area. Consequently, contractual limitations impede NASA's capacity to mandate specific design changes or require instrumentation that aligns with its data needs.
NASA's efforts in cryogenic fluid management extend beyond the HLS program, with several projects funded under Tipping Point awards. However, these agreements, executed as Space Act Agreements, also present challenges. While they provide flexibility and incentivize private investment, they constrain NASA's ability to direct work and access data necessary for technology maturation.
Despite these challenges, companies like SpaceX are pressing forward with initiatives crucial for NASA's lunar exploration goals. SpaceX's Starship lunar lander project, for example, requires advanced cryogenic fluid management capabilities to establish propellant depots in low Earth orbit. While progress is underway, NASA's ability to access and leverage critical data remains constrained by contractual limitations.
As NASA navigates these challenges, collaboration and dialogue between the agency and its industry partners will be vital to finding solutions that balance the needs of both parties while advancing the frontiers of space exploration.
The exploration of the moon and Mars holds immense promise, but overcoming obstacles such as data rights limitations is essential for realizing these ambitious goals. Through continued collaboration and innovation, NASA and its partners can surmount these challenges and pave the way for humanity's next giant leap into the cosmos.
