A blue moon

Today, we're blasting off to explore the cosmos. World Space Week is a celebration of all the science and technology that go into exploring and researching our universe, and how it benefits us back on Earth. As well as helping us to understand the universe we live in, space exploration has played an important role in helping scientists develop new medicines, create new power sources and even improve farming techniques. This year's theme is Space and Climate Change; events will be held in 83 countries to celebrate the vital role that space technology plays in understanding and monitoring how Earth's climate is changing.
