The Hubble Telescope, launched in 1990, has captured unparalleled views of the universe, transforming modern astronomy and transfixing the world with its spectacular images. But building this orbiting observatory would prove to be a rollercoaster ride for all involved, requiring engineers, scientists, and astronauts to venture into uncharted territory. From construction to release, from ridicule to redemption, this is the story of the unsung heroes who turned man's quest to uncover the mysteries of the universe into reality.
They are constantly circling hundreds of miles above our heads, driving our daily lives - yet we barely give satellites a second thought. Satellite engineer Maggie Aderin Pocock wants to change all that. She wants to make us realise and appreciate what these unsung heroes of the modern world have done for us. Maggie reveals how satellites have revolutionised exploration, communication, location-finding and spying. She discovers how they have transformed not only the way we see our planet but our understanding of the dangers within it, like volcanoes and earthquakes. Plus, she discovers the jaw-dropping power of the technology used by satellites to make our lives run smoothly.

What if we could travel not just through space, but through time itself? If you could travel through time, would you change the past or the future? What if you found it couldn’t be changed?
