Laying down the law

Future space tourists could face even tougher tests than Dennis Tito before
setting foot on the International Space Station, NASA confirmed last week. The
agency is drawing up a set of minimum training requirements for all ISS
astronauts. NASA wants to avoid a repeat of the embarrassing row with its
Russian partners over whether Tito should go to the ISS. The Russian space
company Energia is already in discussion with its next paying customer.
