摘要

Theoretically yes, but practically no. To move something from low Earth orbit to the orbit of the moon requires an increase in speed of about 3.2 kilometres per second. When it gets near the moon, it will be travelling faster than 2 kilometres per second relative to the moon -so this would have to be reduced to zero to allow a soft landing. The amount of conventional fuel needed for such accelerations and decelerations would be more than the mass of the International Space Station itself, and this fuel would have to be delivered to it from Earth or a source in space. But the thing that makes it practically impossible is that you would have to bring the whole ISS down softly. The gravity on the moon is much less than on Earth, but this would still require attaching rockets all over the station and having them fire together. And even if it were possible to land the ISS on the moon without breaking it, it is not designed to sit on a surface, even under weak gravity.
