The Future of Space Exploration

What will the future of space exploration hold? At the moment there are more than 70 government space agencies. These include the American agency, NASA and the European agency, ESA. There are also a number of commercial companies, like SpaceX. All of these groups have plans for the next giant leaps forward in space exploration.

The International Space Station

The International Space Station (ISS) is a spacecraft large enough for several astronauts to live on at once. It orbits the Earth 400 km above our planet's surface, travelling at 27,600 km/hour. This means it completes 1 orbit of the Earth in 90 minutes! You can sometimes see the ISS at night - you don't need a telescope. It looks like a small, bright dot moving quickly across the sky.
