New Mexico (1945)
Los Alamos, NM produced at least the first 9 atomic bombs built, 5 of these were detonated. 3 in tests and 2 in combat.
Einsteinium was identified for the first time in nuclear tests debris from Eniwetak by Albert Ghiorso and co-workers in 1952; after this isotopes of Es were prepared in laboratory.
To be able to monitor unconditionally all nuclear tests. If nuclear tests are allowed freely, no third party would have rights to observe and provide expertise, no error reporting available, no standard recollection of facts, no responsibility recorded.Read more: Why_is_the_nuclear_test_ban_treaty_important
The first nuclear explosion (Trinity test) was on a 100 foot steel tower in New Mexico (but was not dropped). The first atomic bomb dropped on US soil was on Frenchman Flat on January 27, 1951 in the Nevada Test Site. Above ground tests continued there until July 17, 1962. Underground tests continued until September 23, 1992. Underground tests of subcritical masses continue to this day. A variety of underground tests were performed in several states including Alaska, Colorado, and New Mexico.
No, however in the 50s & 60s we tested nukes in Nevada. The fallout from these above ground tests did not miss a single state of the lower 48 as well as entering parts of both Canada and Mexico. See the maps in the book "Under the Cloud".

France conducted a series of underground nuclear tests primarily at the Mururoa Atoll and Fangataufa Atoll in French Polynesia. These tests took place from 1966 until 1996 and were part of France's nuclear weapons program. The tests faced significant international criticism and protests due to environmental and health concerns.
India conducted its first successful nuclear test in 1974, known as "Smiling Buddha." It was considered a peaceful nuclear explosion for energy purposes. India conducted further nuclear tests in 1998, officially declaring itself a nuclear-armed state.
The first test at Pokhran was in 1974, there were more tests in 1998
it was first noticed with the nuclear bomb tests.
No their scientists were pursuing the idea but later stopped and focused working on the V1 and V2 rockets
There were no nuclear tests in Mississippi.
As of October 2023, there have been over 2,000 atmospheric nuclear tests conducted worldwide. The majority of these tests occurred between 1945 and 1980, primarily by the United States, the Soviet Union, and the United Kingdom. Following the 1963 Partial Test Ban Treaty, which prohibited atmospheric tests, the number of such tests significantly declined. Today, only a few nations continue to conduct nuclear tests underground, with atmospheric tests being largely banned.
Nevada, at NPG/NTS just north of Las Vegas.
No, underground nuclear tests cannot alter the Earth's axial tilt. The axial tilt of Earth is determined by gravitational interactions with other celestial bodies and is not influenced by nuclear tests.
Nevada hosted the most nuclear tests in the United States, primarily at the Nevada Test Site (now known as the Nevada National Security Site). Between 1951 and 1992, over 900 nuclear tests were conducted there. This extensive testing played a significant role in the development and demonstration of U.S. nuclear capabilities during the Cold War era.
