Ages 5 and up. The Hubble story is a human story. Hubble overcame much adversity early on in its mission and demonstrated the great heights NASA is capable of achieving against all odds. Much of that is thanks to the 'Hubble Heroes', including scientists, engineers, and the brave astronauts who flew five Space Shuttle missions to service Hubble. Re-live the highs and lows of NASA's Hubble Space Telescope program in this comprehensive 25th anniversary tribute.
