1) multinational	space mission

5) to carry	life
6) Earth-like	planets
7) Russian-built	Soyuz rocket
8) close	to impossible
9) a whole new phase of	research

1) Why is it difficult to detect planets orbiting other suns?

2) The Cassini-Huygens Mission to Saturn is a multinational space mission

between three space agencies and 17 nations, with a total cost of over $3 billion.

3) Many planetary scientists now believe that meteorites can carry primitive life from one planet to another.

4) Temperature control of a plethysmograph is used to measure minute changes in tissue volume.

5) 14 Jan 2009 for the first time, astronomers have measured light emitted from extra solar planets around sun-like stars using ground-based telescopes.

There are hundreds of points that should be taken into consideration while you are making decisions about what to do after returning to university.

1. The greater the amount of risk that an investor is willing to take on, the greater the potential return.
2. Gravitation, or gravity, is a natural phenomenon in which objects with mass attract one another.
3. Mental and physical stimulation are vital to the well-being of all people, especially elderly adults.
4. A recent U.S. Army study concluded sleep deprivation reduces emotional intelligence and constructive thinking skills.

Because a material that expands will take up a larger volume, its density will decrease.

1. This population ageing can be seen as a success story for public health policies and for socio-economic development/
2. Are there any immediate solutions to the problem of global warming effecting marine life eco-systems at hand?

1) human travel	to Mars.
2) bone density	loss
3) zero gravity	technology
4) age-related	osteoporosis
5) the International	Space Station
6) rapid	ageing
7) to stimulate	skeleton

1) The Perfect Chair ’s ergonomic design and zero-gravity technology positions the body in a neutral position that counteracts gravity’s adverse effects.

2) Although no official deadline for achieving human travel to Mars has been set, a mission to our closest neighbour—136 million to 150 million miles (220 million to 240 million kilometres) from Earth—is imminent, according to some scientists.

3) From age 70, age-related osteoporosis becomes more common in men and can cause spontaneous fractures and increased risk of fractures following falls

4) A method for the prophylaxis or treatment of bone density loss in an animal or human includes the administering to the animal or human an effective amount of necessary vitamins and mineral.

5) The rapid ageing of the population and the strong desires for working by the retired old has become a serious issue on the Japanese pension management

6) Perhaps to stimulate your skeleton means to prevent diabetes. Certainly bone producing cells in mice can pump out a powerful signal that blocks belly fat, and keeps the blood sugar regulated.
