Tomorrow: @UChicagoSCRC's "Science and Conscience: Chicago’s Met Lab and the Manhattan Project" opens at #UChicago. Exploring the research & activism of #UChicago scientists after the first controlled #nuclear chain reaction. #CP1#AtomicAge https://t.co/P1hHHhRFlB
@NASA's #Kilopower space nuclear reactor project, which could someday power a colony on Mars, reached an important milestone when the core was taken critical for the first time. Critical is the point at which the fission chain reaction in the reactor core is self-sustaining.
