Operation Hardtack I was a series of 35 nuclear tests conducted by the United States from April 28 to August 18 in 1958 at the Pacific Proving Grounds. [1] [2]: 212 At the time of testing, the Operation Hardtack I test series included more nuclear detonations than the total of prior nuclear explosions in the Pacific Ocean.
The medical effects of the atomic bomb upon humans can be put into the four categories below, with the effects of larger thermonuclear weapons producing blast and thermal effects so large that there would be a negligible number of survivors close enough to the center of the blast who would experience prompt/acute radiation effects, which were observed after the 16 kiloton yield Hiroshima bomb ...
On 28 June 2024 DoD announced a successful recent end-to-end test of the US Army's Long-Range Hypersonic Weapon all-up round (AUR) and the US Navy's Conventional Prompt Strike. The missile was launched from the Pacific Missile Range Facility , Kauai, Hawaii, [ 12 ] landing more than 2000 miles away in the Marshall Islands . [ 6 ]
A side-effect of the Pascal-B nuclear test during Operation Plumbbob may have resulted in the first man-made object launched into space. The so-called "thunder well" effect from the underground explosion may have launched a metal cover plate into space at six times Earth's escape velocity, although the evidence remains subject to debate.
Six days after the Castle Bravo test, the government set up a secret project to study the medical effects of the weapon on the residents of the Marshall Islands. [32] The United States was subsequently accused of using the inhabitants as medical research subjects without obtaining their consent to study the effects of nuclear exposure. [ 28 ]
In the short and medium term the effects of the iodine and the caesium release will dominate the effect of the accident on farming and the general public. In common with almost all soils, the soil at the reactor site contains uranium , but the concentration of uranium and the isotope signature [ 160 ] suggests that the uranium is the normal ...
A B-2 Spirit dropping Mk82 bombs into the Pacific Ocean in a 1994 training exercise off Point Mugu, California.. With a nominal weight of 500 lb (230 kg), it is one of the smallest bombs in current service, and one of the most common air-dropped weapons in the world.
The 20 g centrifuge at the NASA Ames Research Center. High-g training is done by aviators and astronauts who are subject to high levels of acceleration ('g'). It is designed to prevent a g-induced loss of consciousness (g-LOC), a situation when the action of g-forces moves the blood away from the brain to the extent that consciousness is lost.
