Space golf

Never mind that he has played golf only twice in his life - next week the Russian flight engineer aboard the International Space Station (ISS) is expected to hit a golf ball a record breaking distance in space.

Cosmonaut Mikhail Tyurin plans to begin a spacewalk, set for Wednesday evening, by knocking a lightweight golf ball off a tee placed on the top of the Russian docking port.

"I play ice hockey and my understanding is that it is very similar," he said in an interview during which he discussed the stunt, which is part of the Russian space agency's quest for commercial contributions.

Club maker Element 21 Golf of Toronto is paying the Russians an undisclosed amount for Mr Tyurin's time, which includes plenty of practice swings aboard the space station.

NASA flight director Holly Ridings says the crew is taking the golf stunt seriously and have been doing a lot of practice.

Federal law bars the US space agency from getting any money for its involvement.

NASA held up the golf shot for months while safety experts pored over possible flight paths for the ball to make sure it would not head back toward the station as a dangerous bit of orbital debris.

"Our safety community has done a lot of work to understand and get ready for this task," Ms Ridings said. "There is absolutely no re-contact issue with the space station."

Mr Tyurin, who has been aboard the station since September, is not expected to smack the ball, just tap it with the club. The ball itself weighs just 4.5 grams, instead of the standard issue 45 grams.

Mr Tyurin has to make the shot one-handed because his bulky spacesuit prevents him from bringing his hands together.

Station commander Michael Lopez-Alegria, who is accompanying Mr Tyurin during the spacewalk, will help set-up a camera to film the shot for an upcoming television commercial.

Mr Tyurin's drive is expected to be one for the record books, though not everyone agrees on how long the ball will fly.

NASA predicts it will fall into Earth's atmosphere and be incinerated within three days. Element 21 Golf is betting on it taking three years.

During the Apollo 14 moon mission in 1971, US astronaut Alan Shepard hit a golf ball with a six-iron from the lunar surface and boasted that it travelled "miles and miles" in the low gravity atmosphere.
