What's happening on the space station?

By Zaina Adamu, CNN

High above us, beyond the skies, is the International Space Station, which weighs nearly 1 million pounds and has a wingspan the length of a football field. It has nine rooms, two bathrooms, two kitchens and two mini-gyms, and it is the largest spacecraft orbiting the Earth.

NASA announced this week that an instrument called ISS-RapidScat will be launched to the station in 2014 to improve weather forecasts, by doing things like monitoring hurricanes. It will also help scientists explore the Earth's global wind field; tropical clouds and tropical systems are affected by wind variations caused by the sun.

Another experiment on board is called InSPACE, which stands for "Investigating the Structure of Paramagnetic Aggregates From Colloidal Emulsions." All that means that scientists are studying magnetorheological fluids, which are complex substances that change form or harden when exposed to magnetic fields. These substances could one day be useful in robots, NASA says, acting as a "blood" to make the movement of joints and limbs like that of a living creature.
