Astronaut James Lovell may not have made a small fortune after all by selling his checklist and notes from the almost-disastrous Apollo 13 mission (the one made famous in the Tom Hanks movie of the same name). The list, along with handwritten calculations by Lovell, fetched $388,000 at auction in November. Now NASA is saying not so fast, reports AP. It's not so sure that Lovell actually owned the list in the first place, and Heritage Auctions has put the sale on hold while the matter gets settled. (More astronauts stories.)
