John bouncing out of this world!
Perth repeated its 1962 light show
The veteran astronaut, John Glenn, who is on board the space shuttle Discovery, is continuing a series of experiments into ageing.
Senator Glenn, 77, has swallowed a radio transmitter and a temperature sensor contained in a capsule the size of a large vitamin pill.
During a break from work, he told mission control in Houston that he was enjoying the weightless environment but said it was bringing its own problems.
"This morning I had oatmeal and raisins. I guess with old folks you normally think it goes down an old man's necktie but this time it wound up on my glasses, so you have to think of things like that."
He was restrained by straps when he became the first American to orbit the earth in 1962.
Senator Glenn has once again seen the Australian city of Perth lit up 340 miles (547 km) below him.
The view was recreated at around 0050 local time on Saturday, when lights at major stadiums, skyscrapers and thousands of homes were turned on to provide a bright contrast with the darkness of the surrounding desert.
"The lights show up very well," Senator Glenn said from Discovery. "Please thank everybody for turning them on, will you?"
The 77-year-old senator has said he was having a wonderful time on his trip.
"This is beautiful. The best part of it is, to do a trite old statement, zero-G and I feel fine."
As he took off Senator Glenn gave the thumbs up sign to the onboard video camera and shook hands with some of his six fellow astronauts.
On Friday he was due to start medical tests - during his nine-day voyage, he is to be the subject of numerous experiments to find out about the ageing process and to see how older people fare in space.
Discovery blasted off successfully on Thursday, but lost an aluminium panel two seconds into the flight.
However, mission control said the mishap should not affect the voyage or its landing.
The launch was delayed slightly by an aeroplane entering airspace above the craft.
President Bill Clinton and a host of Hollywood stars were among the 250,000 spectators who watched the takeoff.
Discovery is a luxurious ship compared to the cramped rocket Glenn used in 1962.
The crew of seven will perform more than 80 experiments and release a satellite for two days of solar studies.
Apart from the US crew, the shuttle is also carrying a Japanese researcher and a European Space Agency astronaut from Spain.
