Cosmic glasses for space exploration

How are asteroids and planets formed from stony particles? This question is being explored in an experiment by scientists who have developed beads made of a special type of glass. They form the composition of the rock particles as naturally as possible on a small scale.

Five key findings from 15 years of the International Space Station

The International Space Station is the longest-running continuously inhabited human outpost in space - this year it celebrated its 15th anniversary. As the ISS orbits the Earth it is essentially in a state of free fall, counteracting the Earth?s gravity and providing an ideal platform for science in space.
