DARPA and NASA pick Lockheed Martin for nuclear rocket

NASA and the Pentagon’s Defense Advanced Research Projects Agency have selected Lockheed Martin and BWX Technologies to move forward with development of a nuclear thermal rocket, or NTR, that could blaze a trail for future missions to the moon and Mars.

The Demonstration Rocket for Agile Cislunar Operations, or DRACO, is slated for launch in 2027.

“The DRACO program aims to give the nation leap-ahead propulsion capability,” Tabitha Dodson, DARPA’s program manager for the effort, said today in a news release. “An NTR achieves high thrust similar to in-space chemical propulsion but is two to three times more efficient. With a successful demonstration, we could significantly advance humanity’s means for going faster and farther in space and pave the way for the future deployment for all fission-based nuclear space technologies.”

Dodson told reporters that NASA and DARPA will go 50-50 on the $499 million cost of the project. The two agencies have been working together on the rocket development effort since January.

Aerojet Rocketdyne wins $67M award for Orion thrusters

Aerojet Rocketdyne says it’s received a $67 million contract award from Lockheed Martin to provide propulsion systems for the Orion spacecraft that’ll carry astronauts to the moon during three missions planned for the 2030s.

The contract option for NASA’s Artemis 6, 7 and 8 missions follows up on Aerojet’s work on earlier missions in the Artemis program — including the uncrewed Artemis 1 mission that flew around the moon last year, and the history-making Artemis 3 mission that’s due to put a crew on the lunar surface in the mid-2020s.

“We’re proud to be part of a team that has demonstrated the ability to safely and efficiently carry astronauts on future Artemis missions, effectively ushering in an exciting new generation of human spaceflight,” Aerojet Rocketdyne CEO and President Eileen Drake said today in a news release.

Aerojet says the contract will be managed and performed out of the company’s facility in Redmond, Wash. Work will also be conducted at Aerojet facilities in Alabama and Virginia.

Nuclear deep-space probe gets a new boost from NASA

Seattle-based USNC-Tech has gotten the green light from NASA to continue development of a rapid-response spacecraft that would use a nuclear-powered propulsion system for deep-space exploration.

The company’s proposed Nyx mission is one of six projects receiving Phase II grants from the NASA Innovative Advanced Concepts program, or NIAC. Each grant provides up to $600,000 of support over the course of two years to follow up on Phase I NIAC projects.

USNC-Tech, the advanced-technology arm of Ultra Safe Nuclear Corp., has been working on a next-generation radioisotope thermoelectric generator known as EmberCore. RTGs are basically batteries powered by the decay of radioactive material. They’ve been used for decades for missions ranging from Apollo moonshots to Mars rover treks and deep-space odysseys. EmberCore promises to provide 10 times as much electrical power as the current generation of RTGs.

For the Nyx mission, USNC-Tech envisions adapting EmberCore for an electric propulsion system that could propel a spacecraft to extremely high speeds. “The spacecraft architecture is capable of incredible delta-V on the order of 50-100 km/s,” USNC-Tech’s Christopher Morrison says in the company’s proposal. That would translate to 110,000 to 220,000 mph.

Such spacecraft could theoretically catch up with mysterious interstellar objects like ‘Oumuamua, which zoomed through our solar system in 2017. Other potential missions include detection of objects in the far-flung Kuiper Beltparallax microlensing to look for free-floating planets, and fast trips beyond the solar system’s zodiacal glow.

How power plays could open new frontiers in space

As more and more hardware goes into Earth orbit, and eventually to the moon and Mars, where will the power to run all those machines come from?

That’s one of the questions under consideration at a State of the Space Industrial Base workshop that’s being conducted this week at Seattle’s Museum of Flight.

The workshop, hosted by Space Northwest, is bringing together government, academic and commercial leaders to assess the state of advanced power and propulsion for space missions, as well as the outlook for a Department of Defense initiative known as Hybrid Space Architecture.

Input from the workshop will be combined with insights gained at two other workshops in Florida and New Mexico to help the Pentagon’s Defense Innovation Unit produce its annual report about the space industry’s potential contributions to sustaining America’s leadership on the final frontier.

NASA and DARPA team up on nuclear rocket program

The Defense Advanced Research Projects Agency has taken on NASA as a partner for a project aimed at demonstrating a nuclear-powered rocket that could someday send astronauts to Mars.

DARPA had already been working with commercial partners — including Blue Origin, the space venture created by Amazon founder Jeff Bezos, as well as Seattle-based Ultra Safe Nuclear Technologies, or USNC-Tech — on the Demonstration Rocket for Agile Cislunar Operations program, also known as DRACO. USNC-Tech supported Blue Origin plus another team led by Lockheed Martin during an initial round of DRACO design work.

Now DARPA and NASA will be working together on the next two rounds of the DRACO program, which call for a commercial contractor to design and then build a rocket capable of carrying a General Atomics fission reactor safely into space for testing. The current plan envisions an in-space demonstration in fiscal year 2027.

“With the help of this new technology, astronauts could journey to and from deep space faster than ever – a major capability to prepare for crewed missions to Mars,” NASA Administrator Bill Nelson said today in a news release.

Nuclear power in space? Pentagon boosts two projects

Two Seattle companies have won Pentagon contracts to develop nuclear-powered prototypes for space applications, with orbital demonstrations set for 2027.

The Defense Innovation Unit says Ultra Safe Nuclear Technologies has been tasked with demonstrating a chargeable, encapsulated nuclear radioisotope battery called EmberCore for propulsion and power applications in space.

Plutonium-powered radioisotope batteries have been in use for decades, going back to the Apollo era. For example, NASA’s Perseverance and Curiosity rovers are relying on such batteries to provide the heat and electricity for their operations on Mars.

EmberCore would provide 10 times as much power as those batteries, producing more than 1 million kilowatt-hours of energy using just a few pounds of fuel.

Another Seattle-based venture, Avalanche Energy, will receive backing from the Defense Innovation Unit to continue development of a compact fusion device known as Orbitron. The device, which is about the size of a lunchbox, would use electrostatic fields to trap ions in conjunction with a magnetron electron confinement system.

The resulting fusion reaction would produce energetic particles for generating either heat or electricity, which can power a high-efficiency propulsion system.

Space nuclear power is nearing critical mass

The idea of putting nukes in space may sound like a national security nightmare, but the right kind of nukes are likely to be a must-have for long-term space exploration.

At least that’s the way a panel of experts at the intersection of the space industry and the nuclear industry described the state of things this week during the American Nuclear Society’s virtual annual meeting.

“In order to do significant activity in space, you need power. And in order to get that power … it’s complicated,” said Paolo Venneri, CEO of a Seattle-based nuclear power venture called USNC-Tech.

Even if you build a hydrogen fuel production plant on the moon, or a methane production plant on Mars, the power to run those plants has to come from somewhere. And studies suggest that solar power alone won’t be enough.

“The sun, it’s great, but only within a certain region of the solar system,” Venneri said. “And so if you want to have sustained high-power applications, you need a nuclear power system.”

President Trump boosts nuclear power in space

In what’s likely to be one of the last space policy initiatives of his administration, President Donald Trump today issued a directive that lays out a roadmap for nuclear power applications beyond Earth.

Space Policy Directive 6 calls on NASA and other federal agencies to advance the development of in-space nuclear propulsion systems as well as a nuclear fission power system on the moon.

“Space nuclear power and propulsion is a fundamentally enabling technology for American deep space missions to Mars and beyond,” Scott Pace, the executive secretary of the National Space Council, said in a White House news release. “The United States intends to remain the leader among spacefaring nations, applying nuclear power technology safely, securely and sustainably in space.”

Space-based nuclear power isn’t exactly a new idea: NASA and the Atomic Energy Commission considered thermal nuclear propulsion – a concept that would have involved heating up propellants with a nuclear reactor – way back in the 1970s as part of Project NERVA.

A different kind of nuclear power, which relies on using the heat from radioactive decay to generate electricity, has been used to power space hardware ranging from Apollo lunar surface experiments to the Curiosity rover on Mars. (NASA’s Perseverance rover, which is due to land on Mars in February, also has a radioisotope power system.)

NASA once considered putting a nuclear electric propulsion system on a spacecraft known as the Jupiter Icy Moons Orbiter, but that mission was canceled in 2005. Now there’s renewed interest in missions that require more power than can be generated by solar arrays – and that’s reviving interest in nuclear power for space applications.
