How many nuclear bombs have been used?
Nuclear bombs have been tested since 1945. (Image credit: Getty Images) On July 16, 1945, the U.S. conducted the world's first nuclear bomb test in the New Mexico desert as part of the Manhattan Project, which led to the detonations of atomic bombs on Hiroshima and Nagasaki just weeks later. Since then, at least seven
Breakthrough Nuclear Power for NASA Space Missions
Using low-bandgap III-V materials such as InAsSb in nanostructured arrays to limit potential loss mechanisms, a 25x improvement in mass specific power and ten thousands times decrease in volume from a MMRTG is an early estimate, with higher performance possible depending on operating conditions. TRC technology will allow a proliferation of small versatile spacecraft with
How hot salt could transform nuclear power
Startup Kairos Power has reached two milestones recently for its molten salt-cooled reactor.Kairos Power For more than a month in total, 12 metric tons of molten salt coursed through pipes at Kairos Power in Albuquerque, New Mexico. The company is developing a new type of nuclear reactor that will be cooled using this salt mixture
Poppyseed-sized nuclear fuel cells might power a NASA moon base
Nuclear fuel cells the size of poppy seeds could power NASA’s Artemis lunar base once it begins operations around 2030. Designed by researchers at Bangor University’s Nuclear Futures Institute in the UK, the miniscule power source—dubbed “Trisofuel”—is intended to run on a micro nuclear generator roughly the size of a small car created by Rolls
A third nuclear age? What to expect from US-South Korea summit.
When South Korea President Yoon Suk Yeol arrives at the White House Wednesday for a state visit, conversations are likely to focus heavily on nuclear weapons – and not just the threat posed by North Korea’s growing arsenal. After decades of nuclear nonproliferation consensus, many experts place the world on the doorstep of what could
Regulators: Nuclear plant leak didn’t require public notice
Minnesota regulators knew four months ago that radioactive waste had leaked from a nuclear power plant in Monticello — but they didn’t announce anything about the leak until this week.The delay in notifying the public about the November leak raised questions about public safety and transparency, but industry experts said Friday there was never a
NASA is going back to an old idea as it tries to get humans to Mars. It is teaming up with the Defense Advanced Research Projects Agency (DARPA) to test a nuclear thermal rocket engine in space with the aim of using the technology for crewed missions to the red planet. The agencies hope to
