3. National disgrace

A devastating discovery is turning the crown jewel of astronomy into an embarrassing failure. Hubble isn’t seeing the universe as it should. Why are the pictures blurry? Nasa’s revolutionary telescope is in orbit and the space agency should be celebrating. Instead, it launches an investigation.

Nasa’s Director of Astrophysics, Charlie Pellerin, has been on holiday in Japan. He returns to hear the devastating news. Meanwhile, it’s chief Nasa scientist, Ed Weiler’s job to face the press, and tell the world the truth.

What’s gone wrong? How are they going to fix it? Three hundred and eighty miles above Earth, Hubble floats alone in the darkness, with the problem hopelessly out of reach.
