Cost. Nothing more nothing less. The technology exists, it's just the "dollars".
No space station has been built there yet.
The moon is significantly larger than a space station. The moon is a natural satellite that measures about 3,474 kilometers in diameter, whereas a space station, like the International Space Station, is much smaller, typically spanning around 100 meters in length.
The program that took astronauts to the moon was Apollo. It was not a space station.
No space station has orbited the moon. The first earth-orbiting space station was Skylab.
There has never been a woman on the moon. Helen Sharman was the first British woman in space (and the only person of sole British nationality to go into space), but she never went to the moon. She was 27 years old and 11 months old when she visited the Mir space station.
She has never been to the Moon. The furthest she has been is low Earth orbit.
Salyut were a series of space stations built by the Soviet Union in the 1970's-early 1980's in response to the American moon landings and Skylab space station. They were intended to show the USSR had the upper hand over the US in space station technology after the failure of the Soviet moon program. In total nine Salyut space stations were flown, being replaced by the larger and more sophisticated Mir space station in 1986.
None. The space shuttle is not built for moon landings.
In 1960 the "space race" began between the US and Soviets. Both worked to get to the moon first and in 1969 the US landed on the moon. The Soviets never have landed. The space race was just another outcome of the Cold War. The ability to launch a rocket has military advantages whether it has a payload for space or for military uses.
Dave Williams has not bin on the moon, nor did any other Canadian astronaut has.
The moon is a different environment than low Earth orbit where the International Space Station is located. Building a space station on the moon would require different technology, resources, and infrastructure compared to one in low Earth orbit. Additionally, the moon's surface is not a stable platform for long-term habitation due to factors such as extreme temperature variations and lack of atmosphere for protection.
The Moon, The International Space Station.
