The prototype space shuttle that arrived in New York City by air earlier this spring is on the move again, this time by sea.
The Enterprise had been parked at Kennedy Airport since it flew from Washington to New York atop a 747 jet.
The shuttle was placed on a barge Saturday and readied for a slow journey through the harbor to its permanent home at the Intrepid Sea, Air & Space Museum on Manhattan's West Side.
The barge was being taken across New York Harbor to Port Elizabeth, N.J. on Sunday.
Then, on Tuesday, a tugboat is to move the Enterprise to the Intrepid, a decommissioned aircraft carrier.
Plans are in place for a floating crane to lift the spacecraft onto the flight deck.
Here is a photo gallery of the shuttle's journey toward its new home.
