HSC Mast for Extreme Environments

Opterus proposes to develop and test a high-performance high-strain composite (HSC) mast for lunar, Martian, and deep-space applications. Building on the existing TCTM boom and deployer developed for orbital applications, this effort will enhance durability, expand the operational temperature range, assess the effects of lunar regolith damage, and increase lifting capacity for extraterrestrial use. Originally designed for zero-gravity deployment, the TCTM boom must be adapted to withstand extreme temperature fluctuations, regolith abrasion, and gravitational loads. Through environmental testing, Opterus will evaluate structural performance, identify design improvements, and conduct an analytical scaling study to refine the system for long-term reliability. These advancements will position the TCTM boom as a versatile, cost effective, and scalable mast technology for lunar solar arrays, communication towers, and space infrastructure, expanding its utility across planetary and deep-space missions. The intended use of the funding will be to support the testing of the TCTM boom in extreme environments and incorporate the insights into the development of an improved TCTM boom capable of use in these extreme extraterrestrial environments. In addition to enabling critical lunar infrastructure, Opterus has identified an express commercial need for shorter but more mass and volume efficient mast solutions. Opterus is confident this boom technology will enable other applications such as commercial companies pursuing in-situ resource utilization. Improvements to the boom in extreme thermal environments could enable other applications such as deep space exploration.

The main purpose of this Phase I effort is the testing and development of Opterus’ existing Trussed Collapsible Tubular Mast (TCTM) for extreme environments, supporting NASA’s immediate goal of developing lunar infrastructure while also contributing to future Mars habitation efforts. By refining the TCTM design to withstand the harsh conditions of extraterrestrial environments, this effort aims to expand its applicability beyond its current orbital use, enabling a broader range of planetary and deep-space missions. As lunar infrastructure expands, the demand for large, lightweight mast systems to support communications, energy harvesting, and lighting will become increasingly critical. On the Moon, masts will be essential for hoisting large fixed and mobile vertical solar arrays, particularly at the South Pole, where continuous solar exposure can be leveraged for power generation. Additionally, these structures will be required to position communication systems, power-beaming equipment, and lighting solutions for permanently shaded regions. Beyond power and communication, rugged and robust masts could facilitate payload offloading, vehicle plume shield positioning, and compact habitat construction for future crewed missions. The scalability of the High Strain Composite (HSC) TCTM will allow for a wide range of planetary infrastructure applications, ensuring adaptability to evolving mission needs. Beyond lunar and planetary applications, the TCTM boom could play a vital role in deep-space missions. Its rollable, compact stowing capability makes it ideal for deployable boom arms used in deep-space sampling or drilling missions, while its low-mass structure would help reduce thermal regulation demands on spacecraft prior to deployment. This Phase I effort will enhance the TCTM boom for deep-space exploration by improving thermal resilience, minimizing the need for major redesigns or extensive testing beyond mission-specific adjustments. A growing commercial sector is emerging around future lunar infrastructure, with companies targeting a range of industries and mission objectives in the developing lunar and Martian economies. Opterus has engaged with several organizations developing technologies to support this new era of space exploration. Among the most critical sectors in this expanding economy are energy generation and in-situ resource utilization (ISRU), both of which will be essential for sustainable lunar operations. These two industries will be closely linked, as ISRU missions depend on reliable mobile power solutions. Opterus is exploring opportunities ranging from 50kW portable vertical solar array and communication towers to support spacecraft propellant generation on the lunar surface to solar arrays integrated into manned rovers for extended surface exploration. These missions demand highly mobile, scalable, and durable energy infrastructure, often operating autonomously with minimal maintenance over long mission lifetimes. Beyond lunar ISRU, deep-space applications such as asteroid mining and space-based infrastructure will benefit from the boom improvements developed in this Phase I effort. The ability to function in extremely cold environments will support operations like deep-space drilling and sampling with minimal thermal regulation requirements, reducing spacecraft power demands. Additionally, enhanced dust tolerance will be critical for the boom’s survival in harsh conditions, where exposure to ejected material from drilling operations could otherwise degrade performance. By improving the thermal resilience, mobility, and dust tolerance of the TCTM boom, this effort will contribute to future deep-space commercialization, enabling long-duration ISRU missions, asteroid resource extraction, and scalable space infrastructure. These advancements will position Opterus as a key technology provider in the growing lunar and deep-space economies.

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.
