Yes. No one has found water or ice on the moon.
Europa is a moon of Jupiter known for its ice-covered surface. Beneath this icy crust, scientists believe there may be a subsurface ocean of liquid water, making it one of the most promising places in the solar system to search for signs of extraterrestrial life. The surface features include ridges and cracks, indicating geologic activity.
Your on it.
