In this second video of NASA's Hubble Memorable Moments series celebrating Hubble's 25 years, the team scrambles to work out an unusual solution to a problem encountered during an instrument repair. The Space Telescope Imaging Spectrograph, or STIS, was installed on Hubble during Servicing Mission 2 in 1997. The versatile instrument was heavily used until a power supply failure in 2004. The Hubble team spent years preparing for a complex repair task in 2009 on the final servicing mission. But no matter how prepared you are, there is always the possibility of an unexpected obstacle.
