Good Movie - But I have a question

Rating: 8/10 (27 November 2014)

Movie is exceptionally good - The fate of the earth seems to be realistic and the future of human beings are depicted very well. The CG work and the overall performance of all the characters including the robots TARS / CASE. The pace of the movie is also maintained well from the point when cooper leaves his family behind and leaves home. The depiction of saturn was simply WOW.
One question: I understand that once cooper passes all the necessary codes to solve the equation the tesseract dissolves away. But how did Cooper and TARS managed to escape the black hole and passed through the worm hole without the ship and reached the cooper station.
