In this April 11, 1970 file photo, Apollo 13 commander James A. Lovell Jr., foreground, speaks during a news conference in Cape Kennedy, Fla. before the spacecraft launched on its ill-fated journey to the moon. At center is astronaut Fred Haise. NASA is questioning whether Lovell has the right to sell a 70-page checklist from the flight that includes his handwritten calculations crucial in guiding the damaged spacecraft back to Earth. The document sold at a November auction for $388,000. (AP Photo)
