“Preparing for Hubble’s Servicing Mission 4 (“SM4”)” begins with a little Hubble Space Telescope before describing some of the repairs, replacements, and tune-ups astronauts have to do to keep it working. It includes some of the “hits” from the camera that was replaced by the WFC3 camera. An accompanying educator’s guide includes discussion questions and answers as well as definitions for key terms.
