Nuclear Power Could Help Future Moon Missions 'Survive the Night'
The heater will provide 5 watts of thermal energy to help spacecraft survive the 14-day lunar night.
- On Wednesday, Firefly Aerospace announced a partnership with Zeno Power to integrate a nuclear heating system onto a Blue Ghost lunar lander, with launch targeted for no earlier than 2028.
- Following the 2025 mission where Blue Ghost ceased functioning after sunset, the collaboration aims to overcome the extreme cold temperatures that disable solar-powered equipment during the lunar night.
- Zeno's Survive-the-Night package features a five-watt Radioisotope Heater Unit containing americium-241 that generates heat through radioactive decay, allowing critical lander components to operate through the 14-day lunar night.
- Ray Allensworth, Vice President of Spacecraft at Firefly Aerospace, said the technology will "extend missions beyond sunset" and support long-duration surface operations required for NASA's Moon Base initiative.
- Firefly maintains a manifest including future missions to the Moon's far side scheduled for no earlier than 2027 and a separate mission targeting the Gruithuisen Domes set for 2028 or later.
