The ATBT (Atmospheric Test Ban Treaty) of 1963.
The Partial Test Ban Treaty, signed in 1963, prohibited nuclear testing in the atmosphere, underwater, and in space. This treaty was signed by the United States, the Soviet Union, and the United Kingdom.
That is called the Partial Test Ban Treaty. It was signed in 1963 and banned the testing of nuclear weapons in the atmosphere, outer space, and underwater.
The Limited Test Ban Treaty, signed in 1963, prohibited nuclear tests in the atmosphere, in outer space, and underwater. This allowed for a reduction in tensions between the USA and the USSR by lessening the risk of radioactive fallout and environmental damage caused by nuclear tests.
It's possible, though it's (probably... see below) prohibited by both the Outer Space Treaty and the Partial Test Ban Treaty of 1963. All countries known to possess nuclear weapons capability, with the exception of North Korea, have ratified at least one of these (North Korea has signed, but not ratified, the Outer Space Treaty).Whether or not a non-weapon nuclear explosion (for example: using a nuclear device as a sort of improved dynamite for, say, mining purposes) would violate the Outer Space Treaty is an interesting legal question, since the treaty expressly refers to nuclear weapons and goes on to say that the use of any equipment or facility necessary for peaceful exploration shall not be prohibited. This could potentially eventually become important.
Yes, why couldn't they? An ICBM carries its nuclear warhead into space and then releases it allowing it to fall from space onto its target. Several hydrogen bomb tests had been performed by the US in space in the early 1960s (one of these caused a delay to a Gemini space mission due to a radiation belt it created that could hurt the astronauts). A project to build spacecraft propelled by nuclear explosions called Project Orion began in the middle 1950s and was stopped in 1963 when the Atmospheric Test Ban Treaty prohibited nuclear explosions in space.
Limited Nuclear Test Ban Treaty
The Partial Test Ban Treaty, signed in 1963, prohibited nuclear testing in the atmosphere, underwater, and in space. This treaty was signed by the United States, the Soviet Union, and the United Kingdom.
The Limited Test Ban Treaty forbids nuclear testing in all areas except underground. Nuclear testing in the atmosphere, under water, and in outer space are all banned.
The Limited Test Ban Treaty of 1963.
Prohibits nuclear weapon test explosions and any other nuclear explosions in three environments: in the atmosphere, in outer space and underwater, but does not prohibit underground nuclear explosions
August 5th, 1963 Three of the four nuclear powers sign a limited treaty that bans most, but not all, nuclear weapons testing. The 1963 treaty only banned "Atmospheric" tests (in the air, space, and underwater) not "most". Testing just moved underground and continued at about the same pace, maybe even faster for a while.
The Nuclear Test Ban Treaty of 1963 allowed underground nuclear testing because it was difficult to monitor. The treaty focused on banning testing in the atmosphere, underwater, and in outer space due to the health and environmental risks associated with the release of radioactive fallout. Underground testing was considered less harmful and easier to conceal.
On August 5, 1963, representatives of the United States, Soviet Union and Great Britain signed the Limited Nuclear Test Ban Treaty, which prohibited the testing of nuclear weapons in outer space, underwater or in the atmosphere.
That is called the Partial Test Ban Treaty. It was signed in 1963 and banned the testing of nuclear weapons in the atmosphere, outer space, and underwater.
