Can astronauts lose internet behind the Moon?

When astronauts are behind the Moon, the Moon itself physically blocks radio waves needed for internet and other communications with Earth. This means they can't just stream Netflix or check their emails until they swing back into line of sight. Space agencies use satellites and relay stations to reduce these dead zones, but the Moon's bulk makes total coverage tricky. So, yes, internet dropout behind the Moon is real — no magic space Wi-Fi boosters exist yet.
