Disclosed is an expansion assembly and method to expand tubulars. In embodiments, an expansion assembly for disposition in a wellbore includes an expandable tubular and an expansion tool that has a swage and a thruster. In addition, the expansion tool has a front anchor assembly that has a front anchor having an open position providing an anchoring relationship with the internal wall and a closed position providing the front anchor with a diameter less than an internal diameter of the expandable tubular. The front anchor assembly also has a sensor positioned on an opposing side of the front anchor from the expansion swage providing that while the sensor is positioned inside the internal wall the front anchor may be in an open position or in a closed position while upon exit of the sensor from the end portion the sensor brings the front anchor in a permanently closed position.
