On this #MemorialDay, we honor all the men and women who have served our country in the military, including many of the astronauts who deployed and serviced Hubble. This year we remember astronaut Bruce McCandless, whom we lost in December 2017. His remarkable career as a Navy captain and NASA astronaut included helping to deploy Hubble in 1990.
