KEY POINTS:
The international space station is about to get all the comforts of a modern, high-end, "green" home: a fancy recycling water filter, a new fridge, extra bedrooms, workout equipment and the essential half-bath.
Later this week, space shuttle Endeavour's seven astronauts will carry up all the frills for more luxurious space station living - and a larger household. Liftoff is set for Saturday.
It will be a home makeover in the extreme. The space station will go from a three-bedroom, one-bath house with kitchenette to a five-bedroom, two-bath house with two kitchenettes and the latest gizmos Nasa has to offer.
