The primary task assigned to ACT was ensuring VIPER's ability to "Survive Lunar Night"-a challenge that involves prolonged periods of darkness, with temperatures plummeting to liquid nitrogen levels on the Moon. In overcoming this engineering hurdle, ACT shipped the meticulously developed TMS to NASA's Johnson Space Center in Houston, where it is scheduled for its final integration into the VIPER rover.

The core of the Thermal Management System consists of four Loop Heat Pipes (LHPs) and a quartet of radiators. These LHPs play an essential role in regulating the heat generated by VIPER's science instruments and avionic systems during lunar excursions. Functioning akin to a circulatory system, these advanced heat pipes efficiently divert heat away from mission-critical hardware. The radiators then dissipate this heat into the Moon's harsh environment, negating the risks of overheating and thereby increasing the longevity of the rover.

An intriguing facet of the TMS is ACT's proprietary passive thermal control valves integrated into each Loop Heat Pipe. These valves afford a level of finesse in thermal regulation by temporarily disabling heat rejection. This innovation allows the rover's scientific instruments and avionic systems to maintain operational temperatures during the extremely cold lunar nighttime, a key to the mission's success.

To add another layer of reliability, ACT also incorporated cross-linking Constant Conductance Heat Pipes (CCHPs). Though CCHPs are already a staple in space applications, ACT's design employs the Moon's partial gravity to enhance both heat transport capabilities and vibration management. This dual-purpose design links two separate surfaces of the rover, providing redundancy in thermal transport.

Throughout the project's lifespan, ACT maintained a symbiotic relationship with NASA, ensuring the Thermal Management System met all of the space agency's stringent criteria. "The successful development and delivery of the Thermal Management System for the NASA VIPER mission exemplifies ACT's unwavering commitment to pushing the boundaries of thermal management technology in support of space exploration," said Bryan Muzyka, ACT's VP of Sales and Marketing. "We are honored to have worked with NASA on this mission and are extremely proud of the large team that worked on this program. We look forward to witnessing VIPER's groundbreaking discoveries on the lunar surface."

As NASA continues to expand its celestial frontiers, ACT's contributions in thermal management stand as a testament to the firm's innovation and expertise. With the TMS now awaiting final integration, ACT establishes itself as an indispensable player in the ongoing journey of lunar exploration.
