Lancaster, Pennsylvania, September 8, 2021 / PRNewswire / -NASA, Advanced Cooling Technologies, Inc. at (ACT) $ 3.7 million We have completed the design of the Volatiles Investigating Polar Exploration Rover (VIPER) and have a contract to manufacture a thermal flight control system.
A key part of the Artemis program, VIPER is a golf cart-sized rover that roams the South Pole of the Moon for miles and provides close-up views of the location and concentration of ice during a mission of about 100 days. .. The Artemis program achieves many âfirstsâ for NASA and the global space community. VIPER is NASA’s first lunar robot rover and the first resource mapping mission on the surface of another celestial body. In addition, the thermal control system jointly developed by ACT and NASA will be the first system to maintain 100 days of mission operation in the shadows. âIt’s exciting to demonstrate some of the best passive thermal management solutions for these important missions,â he said. Bill Anderson, chief engineer of ACT.
As part of the agreement, Advanced Cooling Technologies (ACT) will offer a combination of high-performance passive thermal technologies specifically designed to meet the challenges associated with long-range lunar missions.
- Loop heat pipe (LHP) with integrated heat control valve (TCV)
- Ammonia constant conductance external heat pipe (CCHP)
- Honeycomb radiator panel with integrated constant conductance heat pipe (CCHP)
In addition to flight articles, ACT will work with the team at NASA’s NASA Johnson Space Center to provide thermal analysis, verification and thermal testing at the system and subsystem level. Houston And NASA’s Marshall Space Flight Center Huntsville, Alabama..All flight items will be delivered by June 2022, Meets NASA’s important launch schedule. The images below show VIPER mockups and various aspects of the thermal control equipment developed during the technical demonstration phase.
As mentioned above, one of the most difficult aspects of the VIPER mission is to operate in a shady state. Due to the moon’s slow rotation relative to the sun, the ambient temperature drops downward. 100K (-280F) About 14 Earth days. This has been avoided in the past, including the Apollo program, which landed on moonlight morning. To enable long-term scientific missions to the Moon, electronics must be maintained above a viable temperature in the shadows. The hardware developed by ACT dramatically reduces the amount of heat needed for survival from hundreds of watts to tens of watts. This greatly reduces the amount and mass of solar energy required for the rover. Ultimately, it extends the lifespan and functionality.
This program follows on from the technical demonstration program, which ended earlier this year. During this phase, ACT provided NASA with an Engineering Demonstration Unit (EDU) to further verify and test the performance of the thermal equipment. The collaboration between NASA and ACT dates back more than 10 years since ACT was established as a company in 2003. Many of VIPER’s temperature-controlled critical technologies have been developed and created as part of the Small Business Innovation Research program. (SBIR). A development program more than 10 years ago. âNASA and ACT have been working on these technologies for many years, and the team is thrilled to have the opportunity to create a product that will fly to the moon,â he said. Ryan spangler, Chief Aerospace Engineer at ACT.
This program was also made possible through continued investment in ACT’s space system capabilities. ACT is a global leader in space heat pipe capabilities with system-level design and expertise in manufacturing high-quality, reliable hardware. Over the past five years, ACT has dramatically increased CCHP production, reaching over 50 million failure-free flight hours, gaining a spaceflight legacy with the copper-water space heat pipe (SCWHP), Mars, we have cutting edge technology for future extreme environments missions such as Mars. , And Jupiter (in addition to the moon!).
