ANS Nuclear Matinee: Mars Rover Curiosity, A Nuclear Powered Mobile LaboratoryANS Nuclear CafeAugust 3, 2012, 6:00AM|ANS Nuclear CafeEarly on Monday morning (1:31AM Eastern Daylight Time), after having traveled 352 million miles, NASA's robotic rover Curiosity is scheduled to touch down inside the Gale Crater on the surface of Mars. Soon after, it will begin looking for clues about possible early forms of Martian life.The Curiosity rover carries much more scientific equipment than previous Mars rovers. How to run so much heavy, power-intensive scientific research equipment for a mobile laboratory on another planet? Nuclear power!Ashwin Vasavada, deputy project scientist for the Mars Science Laboratory, explains in this week's video.Tags:nasanuclear technologyplutoniumspace applicationsShare:LinkedInTwitterFacebook
U.K. launches study into nuclear-powered space explorationA new research contract between the U.K. Space Agency and Rolls-Royce will see planetary scientists working together to explore nuclear power as an energy source for deep space missions in the decades to come. The effort is similar to one that the United States is undertaking through NASA."Space nuclear power and propulsion is a game-changing concept that could unlock future deep-space missions that take us to Mars and beyond," said Graham Turnock, chief executive of the U.K Space Agency, on January 12. "This study will help us understand the exciting potential of atomic-powered spacecraft, and whether this nascent technology could help us travel further and faster through space than ever before."Go to Article
The year in review 2020: Research and ApplicationsHere is a look back at the top stories of 2020 from our Research and Applications section in Newswire and Nuclear News magazine. Remember to check back to Newswire soon for more top stories from 2020.Research and Applications sectionARDP picks divergent technologies in Natrium, Xe-100: Is nuclear’s future taking shape? The Department of Energy has put two reactor designs—TerraPower’s Natrium and X-energy’s Xe-100—on a fast track to commercialization, each with an initial $80 million in 50-50 cost-shared funds awarded through the Advanced Reactor Demonstration Program.

New U.S. space nuclear policy releasedAn artist's concept of a fission power system on the lunar surface. Image: NASAA national strategy for the responsible and effective use of space nuclear power and propulsion (SNPP)—Space Policy Directive-6 (SPD-6)—was released by the White House on December 16 as a presidential memorandum.Space nuclear systems include radioisotope power systems and nuclear reactors used for power, heating, or propulsion. Nuclear energy can produce more power at lower mass and volume compared to other energy sources and can shorten transit times for crewed and robotic spacecraft, thereby reducing radiation exposure in harsh space environments. SPD-6 establishes a road map for getting space nuclear systems into service and sets up high-level goals, principles, and federal agencies’ roles and responsibilities.Go to Article
EU Taxonomy to Include Nuclear Energy as Sustainable Energy Source ANS PositionA PDF version of the letter can be downloaded here. I write on behalf of the American Nuclear Society (ANS) to recommend the EU’s inclusion of nuclear energy as a sustainable energy source securing Europe’s prosperous future. ANS and the 10,000 nuclear technology professionals it represents are committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit humanity.Go to Article
ANS signs agreement with Spanish Nuclear SocietyThe American Nuclear Society and Sociedad Nuclear Española (SNE) on December 10 signed a memorandum of cooperation (MOC) that creates a partnership between the two societies to cooperate in promoting the development of nuclear science and technology for peaceful purposes.Go to Article
IAEA awards fellowships to 100 female students in nuclearThe International Atomic Energy Agency has awarded fellowships to the first group of 100 female students from around the world under a new initiative to help close the gender gap in nuclear science and technology.The Marie Sklodowska-Curie Fellowship Program, named after the pioneering physicist, was launched by IAEA Director General Rafael Mariano Grossi in March to support women pursuing nuclear-related careers.Go to Article
Nuclear tech in space: What’s on the horizon?Illustration of a Mars transit habitat and nuclear electric propulsion system. Image: NASANASA aims to develop nuclear technologies for two space applications: propulsion and surface power. Both can make planned NASA missions to the moon more agile and more ambitious, and both are being developed with future crewed missions to Mars in mind. Like advanced reactors here on Earth, space nuclear technologies have an accelerated timeline for deployment in this decade.Space nuclear propulsion and extraterrestrial surface power are getting funding and attention. New industry solicitations are expected this month, and a range of proposed reactor technologies could meet NASA’s specifications for nuclear thermal propulsion (NTP). Nuclear electric propulsion could increase the feasibility of crewed missions to Mars with a shorter transit time, a broader launch window and more flexibility to abort missions, reduced astronaut exposure to space radiation and other hazards, expanded payload mass capabilities, and reduced cost.Go to Article
NASA and DOE sign MOU on interplanetary nuclear propulsionA “visionary view” of a nuclear thermal propulsion–enabled spacecraft mission. Image: NASASecretary of Energy Dan Brouillette and NASA Administrator Jim Bridenstine on October 20 signed a memorandum of understanding to continue decades of partnership between the Department of Energy and NASA and to support the goals of NASA’s Artemis program. These include landing the first woman and the next man on the moon by 2024 and establishing sustainable lunar exploration—using nuclear propulsion systems—by the end of the decade to prepare for the first human mission to Mars.Go to Article
DOE ends dispute with South Carolina on Pu removalThe DOE is working to remove plutonium stored at its Savannah River Site.The Department of Energy has reached a settlement with the state of South Carolina to remove 9.5 metric tons (t) of plutonium from the state, the agency announced on August 31. Under the settlement, which resolves litigation over the storage of surplus plutonium at the Savannah River Site near Aiken, S.C., the state will receive an upfront lump sum of $600 million in economic and impact assistance payments. In return, the DOE will be allowed more time (through 2037) to remove the plutonium from the state without the threat of lawsuits.The settlement stems from the DOE's termination of the Mixed Oxide (MOX) Fuel Fabrication Facility in 2018. The MOX facility was intended to meet a nonproliferation agreement between the United States and Russia to dispose of 34 t of weapons-grade plutonium by converting it to nuclear fuel for commercial power reactors. Reported to be 70-percent completed when construction was halted, the MOX facility was approximately $13 billion over budget and 32 years behind schedule, according to the DOE.Go to Article
NASA work on lattice confinement fusion grabs attentionAn article recently published on the IEEE Energywise blog heralds “Spacecraft of the Future,” which could be powered by lattice confinement fusion. While lattice confinement fusion is not a new concept and is definitely not ready for practical applications, it has been detected within metal samples by NASA researchers at the Glenn Research Center in Cleveland, Ohio, using an electron accelerator–driven experimental process.Go to Article
