Final spacewalkers of Nasa's 30-year shuttle mission

159 space walks totalling 1,000 hours to build the station and keep it running

These stunning images capture the final stage of the construction of the International Space Station.

But as they marked the beginning of a new era in space exploration, the spacewalk undertaken by Gregory Chamitoff and Mike Fincke also represented an end - of Nasa's 30-year shuttle programme.

All future spacewalks - including one during the final shuttle voyage this summer - will be performed by full-time space station residents.

'This space station is the pinnacle of human achievement and international co-operation,' spacewalker Gregory Chamitoff observed before heading back inside.

'Twelve years of building and 15 countries and now it's the Parthenon in the sky and hopefully the doorstep to our future. So congratulations everybody on assembly complete.'

The two astronauts completed construction of the International Space Station with the smooth addition of an extension boom.

Mr Chamitoff said it was fitting for Endeavour to be present for the last spacewalk by a shuttle crew - conducted on the next-to-last flight of the shuttle era - since it was present for the first in December 1998. It was the fourth spacewalk in a week for the Endeavour astronauts, who will head back to Earth in just a few days.

Mr Chamitoff and his spacewalking partner, Mike Fincke, teamed up with robot arm operator Gregory Johnson to accomplish the last construction job.


The space shuttle Endeavour first made the voyage to the International Space Station in 1992

Mr Fincke is due to pass the US record of 377 days in space. He spent six months living on the space station - twice. This is his first shuttle trip; he previously rode Russian Soyuz rockets into orbit.

'I could not share this moment with a group of better people, including our friends on the ground,' he radioed.

Endeavour and its crew of six will leave the space station late on Sunday night. Landing is set for the pre-dawn hours of Wednesday during a rare touchdown in darkness.

Tuned in: Hospital takes classical approach to soothe newborns... by playing Mozart through headphones

Lullaby: Newborn Nela listens to Mozart in Slovakia


A clinic in Slovakia has found a way to comfort newborn babies that are separated from their mothers for treatment - classical music.

Using regular size headphones that appear gigantic on the babies' tiny heads, the maternity ward in Kosice-Saca hospital has them listening to Mozart or Vivaldi.

During a recent visit to the clinic, chief Dr. Slavka Viragova said the music functions as a replacement for a mother's voice and is helping the babies breathe regularly and maintain a proper heart beat.

It seems to have struck a chord with two-day-old Nela, below.

Dr. Slavka Viragová, who launched the music project, claims that Mozart helps the infant to recall the mother when she is not with them.

She said: 'The birth trauma is enormously stressful for the baby. Music therapy helps a baby to gain weight, get rid of stress and handle pain better.'

The babies listen to soothing music 5-6 times a day, from Mozart to natural forest sounds. Nurses also use the method to care for premature babies as it helps to stabilise their breathing.

Is it a unicycle? Is it a motorbike? Unveiled: The transforming 'dicycle' that can fit in a lift

Transformers: The electric-powered Uno III Streetbike - or U3 - can convert itself with the push of a button from a conventional motorbike to unicycle-style machine


Dispatch riders and couriers know the fastest way to weave through heavy traffic is on a motorbike.

But for those jams even two wheels can't navigate, a new solution has been developed.

Just like a Transformer, the Uno III Streetbike - or U3 - can convert itself with the push of a button from a conventional motorbike to unicycle-style machine.


Robots in disguise: The Tron style motorcycle leathers are optional


The electric-powered machine balances on two parallel rear wheels, the front retracting between them to allow it to manoeuvre through spaces so tight it can be driven into a building - and even fit in the lift.

Then, when it's time to zoom off into the sunset, the front wheel slides forward as the rear pair move back, giving the vehicle the stability to pick up speeds of up to 30mph.

It can travel between 30 to 35 miles on a single three to four hour charge.


Through the evil eye: This diagram shows the mechanism which allows the U3's transformation


Now the remarkable vehicle is being produced by his own motor design company in Cambridge, Massachusetts, called BPG Motors.

Small enough to fit in indoors, but powerful enough to tackle the road, the makers hope the cutting edge $7,500 (£4,600) ride will revolutionise the morning commute.
