The first man to walk on the moon is recovering from heart surgery just days after his 82nd birthday.

Neil Armstrong is recovering from a heart surgical proceedure he had Wednesday. No one knew about the incident that led to this surgery, however, his wife, Carol, told a NASA spokesperson that he is doing well.

Although no one knows where he is recovering, many people have been sending him ‘get well’ wishes. NASA Administrator Charles Bolden wished Armstrong a quick recovery from cardiac bypass surgery in a Facebook statement and a message from Aldrin’s twitter wished him well.

Armstrong commanded the Apollo 11 spacecraft that landed on the moon on July 20, 1969. He spent nearly three hours on a moonwalk with fellow astronaut Edwin “Buzz” Aldrin.
