Astronaut fights to keep moon mountain named after wife

When Captain Jim Lovell's Apollo 8 crew reached the moon in 1968, he named a mountain "Mount Marilyn" as a tribute to his wife.
But the former astronaut was disappointed to learn that the International Astronomical Union, which is responsible for naming celestial objects, has disregarded the name.
The IAU recently said that it would consider public opinion in future when naming objects - which has prompted Lovell to ask for "Mount Marilyn" to be recognised as an official name.
Captain Lovell told BBC Radio 5 live's Up All Night: "I kind of figured that being the first explorers there, that we should... at least have the choice of naming something."
