NASA officials refused to comment Monday on published reports that both NASA and a private contractor overlooked test results that detected the Hubble Space Telescope's crippling mirror flaw before launch.

NASA is to release results of a five-month, independent investigation into the woes of the $1.5 billion space telescope Tuesday afternoon.The Washington Post and Hartford Courant on Monday said the report will attack both NASA and Perkin-Elmer Corp., of Danbury, Conn., the company that made the faulty mirror that has blurred Hubble's vision.
