WASHINGTON (AP) [–] The United States expressed doubt on Monday about Iran’s claim that it safely returned a monkey from space, saying it is questionable that the monkey survived [–] or if the flight happened at all.

State Department spokeswoman Victoria Nuland said a lot of questions remained “about whether the monkey that they reportedly sent up into space and reportedly came down was actually the same monkey, whether he survived.”

“The Iranians said they sent a monkey, but the monkey that they showed later seemed to have different facial features,” Nuland told reporters. “He was missing a little wart.”

Tehran blames the confusion on Iranian media for initially using a photo of a backup monkey. It says the monkey orbited and returned safely, and President Mahmoud Ahmadinejad added Monday that he would consider being Iran’s first astronaut in space.

Nuland described Ahmadinejad’s proclamation as an “interesting choice,” but was more diplomatic than Sen. John McCain, R-Ariz., who joked about Ahmadinejad’s ruminations earlier Monday.

“Wasn’t he just there last week?” McCain said in a tweet and linked to a story about the space-orbiting monkey.

Jonathan McDowell, a Harvard astronomer who tracks rocket launchings and space activity, backed up Iran’s claim that monkey space flight was real. However, he had a slightly different explanation for the photo mix-up, saying the simian with the mole died during a failed space mission in 2011.

Iran has never confirmed that a monkey died in 2011, or that there was a failed mission that year.

Tehran says its goal is a manned space flight.

Washington and its allies worry the program may be cover for ballistic missile technology development.
