No the moon did not shift orbit. NASA’s search for water continues on the moon. Unless you live on the moon, NASA attempted to crash a rocket on the moon to try to expose water from the underground polar region. All telescopes were on the moon for signs of large plume of debris, many came out disappointed. NASA with high tech sensitive instruments will further analyze the data and convince a strapped nation for more money to go to the moon. Water is the only means now for space travel, without it there is no reason to leave the planet.
