Remembering James Lovell FILE - In this December 1968 file photo, Apollo 8 crew, from left: Commander Frank Borman, Lunar Module pilot William A. Anders and Command Module Pilot James A. Lovell, Jr. Dec. 21, 2008 sees the 40th anniversary of the launch of the Apollo 8 mission bringing Mission Commander Frank Borman, Command Module Pilot James Lovell and Lunar Module Pilot William Anders. With the death of John Glenn, the last of the Mercury 7 astronauts, and the 2012 death of Neil Armstrong, more of early U.S. space history is fading. But many veteran Apollo and Gemini fliers still carry the rocket flame of those pioneering space exploration days. (AP Photo/File) (Uncredited/ap)

Lovell Jr., left, opens the astronauts televised news conference at the Manned Spacecraft Center, Houston, by saying "I'm not a superstitious man" alluding to the number 13 and the trouble that befell the flight. With Lovell are his fellow crew members, command module pilot John Swigert, center, and lunar module pilot Fred Haise. With their moon-bound spacecraft wrecked by an oxygen tank explosion on April 13, 1970, the astronauts urgently radioed, "Houston, we've had a problem here." Screenwriters for the 1995 film "Apollo 13″ wanted to punch that up. Thus was born "Houston, we have a problem." (AP Photo) (AP)
