Today, we're blasting off to explore the cosmos. World Space Week celebrates the science and technology that go into exploring our universe, and how it benefits us back on Earth. Space exploration has helped 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 champion the role of space technology in understanding and monitoring Earth's climate.
