Senator Barbara Mikulski gestures as she speaks with a member of the Hubble flight operations team. He sits at a long desk with another team member. The desk is covered with computers, keyboards, stacks of paper bound together with o-rings so it can be flipped through easily, and a small Hubble model. Other figures are visible in the background, including someone holding a boom mic to capture their interaction.

Sen. Barbara Mikulski

Following a successful Servicing Mission 4, Senator Barbara Mikulski talks with Michael Prior, Hubble Space Telescope operations manager, while visiting the Space Telescope Operations Control Center at NASA's Goddard Space Flight Center in Greenbelt, Maryland. Mikulski was the longest-serving female senator in the history of the U.S. Congress and an influential leader in space policy.
