On a stage NASA named Ignition, the agency sketched a future in which people stay on the Moon rather than merely visit it, and in which a nuclear-powered craft sets out for Mars before 2028. It is a turn in priorities, from the brief journeys of the past toward a patient presence beyond Earth, and it rests on a simple human need: light and heat that do not depend on the sun.

NASA Unveils 'Ignition' Plan for a Permanent Moon Base and a Nuclear-Powered Mars Mission by 2028
On a stage NASA named Ignition, the agency sketched a future in which people stay on the Moon rather than merely visit it, and in which a nuclear-powered craft sets out for Mars before 2028. It is a turn in priorities, from the brief journeys of the past toward a patient presence beyond Earth, and it rests on a simple human need: light and heat that do not depend on the sun. Whether the schedule holds will be learned not in speeches but in the slow arrival of machines on distant ground.
NASA gathered its plans under the name Ignition and laid out a path toward a permanent human base on the Moon, together with a nuclear-powered spacecraft bound for Mars before the end of 2028. The shift is clear: the agency is placing lasting presence beyond Earth ahead of short missions that come and go.
Administrator Jared Isaacman framed the effort as a national imperative. He pledged a return to the Moon before the end of President Trump's term, a Moon base, and an enduring presence there, and he warned that the race with other great powers would be judged in months rather than years.
The lunar work unfolds in three phases. First come robotic landers, up to 30 of them by 2027, carrying instruments and testing technologies while helping to choose sites near the south pole. The second phase builds the infrastructure of communication, navigation, power and mobility, and crewed flights are expected to grow to several a year. The third phase brings continuous habitation, with long stays, permanent habitats and an outpost that operates rather than visits.
Power sits at the center of it all. Reactors are meant to supply steady electricity through lunar nights of nearly two weeks, when sunlight is absent and life support, science and communications still need energy.
For Mars, NASA intends to launch Space Reactor-1 Freedom, presented as the first nuclear-powered interplanetary spacecraft, to demonstrate advanced nuclear-electric propulsion. Once there, helicopter-style drones are to explore the surface. The plan also tilts resources toward surface operations and long-term habitation, leaving commercial activity in low Earth orbit to private companies. The announcement offers goals and timelines but not budgets or contracts, so the 2027 landers and the late-2028 launch will be the first real measures of whether the schedule holds.
NASA used an event it called "Ignition" to lay out a plan for a permanent human base on the Moon and a nuclear-powered spacecraft bound for Mars before the end of 2028. The roadmap marks a change in priorities: the agency is putting long-term presence beyond Earth ahead of short-term missions.
Administrator Jared Isaacman set the tone. He said NASA is committed to achieving the near-impossible once again: returning to the Moon before the end of President Trump's term, building a Moon base, and establishing an enduring presence. He called for complete alignment on what he described as a national imperative, and said the clock is running in a great-power competition in which success or failure will be measured in months, not years.
The lunar base is organized in three phases. The first is robotic. NASA plans to send up to 30 robotic landers by 2027, carrying scientific instruments and testing technologies meant to support later human missions. Those landers are also expected to help identify the best sites for the base, particularly near the Moon's south pole.
The second phase is infrastructure: communication systems, navigation networks, power generation and mobility tools for astronauts. During this stage NASA expects crewed missions to become more frequent, possibly several a year. The third phase moves to continuous human presence, with long-duration missions, permanent habitats and more advanced surface systems, turning the Moon into an operating outpost instead of a place visited briefly.
Power is central to the design. The base is meant to rely on nuclear reactors for continuous electricity, especially through lunar nights that can last almost two weeks. Solar power depends on sunlight; a reactor does not. Life-support systems, scientific work and communications all need steady supply, and the plan treats nuclear power as the way to provide it.
Mars is the longer-range goal, and nuclear technology figures there too. NASA's statement says it will launch Space Reactor-1 Freedom, described as the first nuclear-powered interplanetary spacecraft, to Mars before the end of 2028. The mission is meant to demonstrate advanced nuclear electric propulsion in deep space. NASA said that approach offers an extraordinary capability for efficient mass transport and enables high-power missions beyond Jupiter, where solar arrays are not effective.
The spacecraft is expected to cut travel time and improve efficiency compared with traditional approaches. Once near Mars, the mission will use helicopter-like drones, similar to earlier robotic explorers, to study the surface and gather data.
The plan also reflects a shift in emphasis. Rather than prioritizing orbital infrastructure, NASA is focusing on surface operations and long-term habitation. That fits with a wider aim of expanding commercial activity in low Earth orbit, leaving private companies a bigger role there while NASA concentrates on deep space.
The coverage describes goals and timelines, not budgets or contracts. What to watch is whether the 2027 landers and the Mars launch by the end of 2028 arrive on the schedule NASA has now set publicly.
