Kevin Mazur/WireImage.comPaul McCartney and NASA's relationship has always been out of this world, but could a little monkey business now come between them?
Read on to find out why McCartney isn't too pleased with the space agency these days...
The former Beatle is unhappy with NASA's recent animal testing, which PETA alleges is cruel and even deadly to our furry friends. In a letter to NASA Administrator Charles Bolden, the singer blasts the space program for apparently funding radiation testing done on spider monkeys.
"I believe NASA has the ingenuity to investigate the health effects of space travel without confining and experimenting on animals," McCartney wrote.
McCartney reminded Bolden of his history with NASA, including a performance for an orbiting space shuttle in 2005. The agency also beamed the Beatles' classic "Across the Universe" into outer space in honor of the 40th anniversary of the song and the 50th anniversary of NASA's founding.
"It would be terribly disappointing if in our zeal to explore new frontiers and to learn about the fascinating universe where we live we began to regress in our treatment of the animals with whom we share this planet," McCartney wrote. "May I appeal to you to cancel this experiment."
Reps for NASA did not immediately comment.
