The University and ispace have entered into a strategic consulting agreement to explore lunar night survivability utilizing Radioisotope Heater Units on the Series 3 lunar lander and rovers. The University was awarded funding under Phase I and Phase II of the UK International Bilateral Fund to create mission concepts leveraging the technology on future missions.

The conditions on the lunar surface are extremely harsh with temperatures falling to minus 170 degrees Celsius during the two-week long lunar nights, when sunlight does not warm the surface. To realize long-term missions, new technology and systems are required to survive the cryogenic environment of lunar night.

The Space Nuclear Power group at the University of Leicester has been developing radioisotope power systems for over a decade. These power systems use the heat generated from the decay of radioisotopes, and can be used to provide heat to spacecraft, or converted to electricity to power key subsystems. The technology development has been funded by the European Space Agency (ESA) European Devices Using Radioisotope Energy (ENDURE) program, which has been heavily supported by the UK Space Agency.

Project lead Dr Hannah Sargeant from the University of Leicester School of Physics and Astronomy and Space Park Leicester said: “The radioisotope power technology that has been developed at the University of Leicester, in conjunction with National Nuclear Laboratory, is performing extremely well in our ongoing testing campaigns. In this project, we will be working with ispace to investigate the feasibility of using radioisotope heater units to provide sufficient heat to spacecraft to endure the lunar night.

“The first phase of UKSA International Bilateral Funding was used to work with our international partners to understand their power needs and mission priorities. In Phase 2, we will be conducting both laboratory and concept studies to demonstrate the feasibility of the mission concepts. It will also provide an opportunity to highlight the technology to the civil and commercial space industry and show how it could be used to meet critical power needs for priority missions.”

“Our work with the University of Leicester to transport UK technologies to the Moon and test their effectiveness against the lunar night is another example of the ispace’s unique capability. This collaboration exemplifies the global nature of the cislunar economy, the importance of academic institutions contributing to the vision, and the potential for great achievements,” said Takeshi Hakamada, ispace Founder and CEO. “As lunar exploration continues to gain attention, ispace, through our business entities around the world, is pleased to collaborate with global organizations to advance scientific understanding through transportation to lunar orbit and the lunar surface.”

ispace’s Japan entity is currently in an advanced design and development phase for the Series 3 lander with partial funding through a Japanese government Small Business Innovation & Research grant through the Ministry of Economy, Trade, and Industry. In addition to the lunar Radioisotope Heater Units, ispace is in discussions with a number of entities to transport payloads to lunar orbit and the surface on future missions.

ispace is leveraging its global presence through its three business units in Japan, the U.S., and Luxembourg, for the simultaneous development of Mission 2, currently planned to be launched in 2024, led by its Japanese office, as well as Mission 3, currently planned to be launched in 2026 and led by its U.S. office, and Mission 6, which will utilize the Series 3 lander and is scheduled to be launched by 2027.
