Taiwan's telecommunications infrastructure has recently become a target in the cross-strait conflict with China. With submarine cables vulnerable to damage, Taiwan is branching into space to ensure the country's communication resilience remains strong. In recent years, satellite providers such as Starlink have helped millions around the world access internet services, and satellites have become an obvious choice for countries interested in strengthening their telecommunications infrastructure. But how many of us really understand these advanced space technologies? We've invited Wu Jong-shinn, aerospace engineer and director of the Taiwan Space Agency, to explain how satellites work and how they benefit society. Wu Jong-shinn draws on his extensive experience in aerospace engineering to explain the relationship between telecommunications and space—and why space matters. You may be wondering: Why are so many countries investing in space technology right now? What does space have to offer the average person? How crucial are satellites to our daily lives? And with so many unsolved problems down here on Earth, is space technology truly worth investing in right now? Wu Jong-shinn answers these questions and more in this episode of "Now You Know."
