A 5-watt nuclear heater is planned to keep lunar equipment operating through 14 days of darkness
Firefly Aerospace (FLY) has partnered with Zeno Power to include a 5-watt americium-241 radioisotope heater on a 2028 Blue Ghost lunar mission. The payload aims to demonstrate technology for operating through the 14-day lunar night, supporting NASA's Moon Base initiative. The mission follows Firefly's successful 2025 lunar landing and upcoming far-side missions.

The 30-second read
Why it matters
The partnership positions Firefly as a pioneer in lunar night operations, potentially attracting further NASA CLPS contracts.
Market read
New payload agreement adds a novel capability to Firefly's lunar services, modestly relevant for investors tracking space sector growth.
What to watch
Potential need for additional safety approvals and the unknown financial terms of the contract.
Background
Firefly Aerospace is a small‑to‑medium lift launch and lunar lander provider; Zeno Power develops radioisotope heater units for extreme environments.
Ticker impact
Firefly Aerospace announced a commercial payload agreement with Zeno Power to fly a 5‑watt americium‑241 radioisotope heater on its Blue Ghost lunar lander, scheduled for no earlier than 2028.
Potential modest upside as the market prices in the contract and technology differentiation; upside limited until launch milestones are met.
The agreement is a fresh contract but without disclosed dollar value; impact depends on execution risk and future NASA funding.
Market effects
Highlights growing demand for lunar thermal management tech, may benefit broader space‑hardware sector.
U.S. space and defense companies could see modest interest.
Demonstrates U.S. leadership in lunar infrastructure, may influence international lunar contracts.
Counterpoint
Execution risk and regulatory hurdles for radioisotope devices could delay or cancel the payload, limiting upside.
