How do you sneeze in a spacesuit? Aim low!

CAPE CANAVERAL, Florida (Reuters) – Veteran spacewalker David Wolf had some advice on Tuesday for those wondering how to sneeze in a spacesuit.

"Aim low, off the windscreen, because it's going to mess up your view and there's no way to clear it," said Wolf, who admitted being in just that predicament during Monday's spacewalk outside the International Space Station.

Wolf and his shuttle Endeavour crewmates took a break from their construction work at the space station to answer questions sent in by followers of commander Mark Polansky's Twitter feed, a web-based short messaging service.

The astronauts are four days into a planned 11-day stay at the orbital outpost, a $100 billion (60.8 billion pound) project by 16 countries.

On Tuesday, the astronauts transferred a locker of science experiments that will be mounted on a new platform on the station's Kibo laboratory.

Wolf and rookie astronaut Chris Cassidy are scheduled to make the third of five spacewalks planned during the Endeavour mission on Wednesday. Their job is to replace batteries in one of the station's solar power panels.
