@NASAHubble Launch New Mini-Series hosted by John Grunsfeld

@NASAHubble is launching a new 6-part mini-series on Instagram about the tools used on Hubble’s servicing missions. Hubble was uniquely designed to be servicwed in space so that components could be repaired and upgraded. Astronauts performed challenging spacewalks on five servicing missions from 1993 to 2009 to keep Hubble operating so that it could change our fundamental understanding of the universe.

Starting tomorrow (Tuesday 16 April), @NASAHubble will release a new episode each Tuesday for the next 6 weeks.
