Idaho Falls is becoming a hub for one of humanity’s most ambitious scientific endeavors: powering spacecraft destined for Mars, the moon, and beyond. The Idaho National Laboratory is playing a critical role in enabling NASA’s deep space exploration programs through advanced nuclear technology, with a high-profile visit from a top NASA official scheduled for Friday underscoring the partnership’s strategic importance.
Jared Isaacman, a NASA official, will tour INL facilities to see firsthand how the laboratory develops the nuclear power systems that keep humanity’s robotic explorers alive in the harsh environments of space. The visit reflects growing recognition that nuclear energy is essential to NASA’s long-term mission objectives—a reality driven home by decades of successful applications across multiple planetary missions.
Powering Mars and Beyond
INL has already demonstrated its expertise in space nuclear technology through proven achievements. The laboratory manufactured radioisotope thermoelectric generators that currently power NASA’s Curiosity and Perseverance rovers on Mars, keeping the vehicles operational in an environment where solar panels become caked with dust and sunlight is limited.
Looking beyond Mars, INL’s contributions extend to even more distant missions. NASA’s New Horizons probe, which traveled nine and a half years to reach the Kuiper Belt and fly past Pluto, also relied on nuclear power systems. These successes showcase the reliability and durability that only nuclear technology can provide when conventional power sources fail in the extreme conditions of deep space.
According to Liza Raley, an INL tour ambassador, “We have made radioisotope thermoelectric generators that have powered the Curiosity and the Perseverance rover that are on Mars.” That track record positions INL as NASA’s trusted partner for even more ambitious missions ahead, as first reported by the Local News 8.
An Accelerated Launch Schedule
The coming months represent a pivotal window for INL-supported space missions. The laboratory is contributing technology to four separate NASA missions set to launch within a compressed 12-month timeframe, demonstrating both the demand for INL’s capabilities and the urgency of NASA’s exploration agenda.
The Dragonfly mission, scheduled for July 2028, will send a rotorcraft to explore Saturn’s moon Titan using radioisotope heater units and a Multi-Mission Radioisotope Thermoelectric Generator developed at INL. That same year, in October 2028, the Rosalind Franklin mission will target Mars with a lander and rover designed for subsurface exploration.
Perhaps most significantly, November 2028 marks the launch of Space Reactor-1, a small fission reactor that will power a nuclear electric propulsion spacecraft bound for Mars. This mission represents a major step forward: instead of relying on radioisotope systems alone, NASA will deploy an actual fission reactor to provide the sustained, high-output power needed for ambitious deep space operations.
Looking further ahead, the Promise rover is scheduled to land on the lunar surface in 2029, powered by a radioisotope thermoelectric generator. NASA is also planning to deploy a nuclear fission reactor to the moon by 2030, establishing the technological foundation for extended human presence on the lunar surface.
The Future of Space Nuclear Technology
INL’s work goes beyond simply powering existing spacecraft designs. The laboratory is actively developing lighter, more compact nuclear reactors and advanced battery systems tailored for space applications. These innovations will enable longer missions, heavier payloads, and more ambitious scientific objectives.
Justin Coleman, director of INL’s Nuclear Reactor Technology Division, explained the philosophy guiding this research: “They don’t need a reactor today. But again, that’s the reason NASA’s looking at a reactor that’ll be launch-ready by 2030.” That forward-thinking approach ensures INL remains on the cutting edge of space exploration technology, as first reported by the Local News 8.
The convergence of INL’s technical excellence and NASA’s mission demands positions Idaho Falls at the center of America’s deep space future. As robotic explorers push further into the solar system and human missions to the moon and Mars move closer to reality, the nuclear technology developed in Bonneville County will be essential to their success.
What Comes Next
With four major missions launching within the next three years and NASA’s 2030 lunar reactor deployment deadline approaching, INL continues expanding its capabilities to meet demand. The Friday visit from NASA leadership signals continued confidence in the partnership—and hints at an even deeper collaboration as humanity’s space exploration ambitions grow increasingly ambitious.
