Deneen Lewis: Hubble Electrical Engineer

Deneen started working on the Hubble project as an electrical engineer in her first job out of school. She has been involved in three of the servicing missions to repair and upgrade Hubble.

During the final space shuttle visit to Hubble, Servicing Mission 4 in 2009, she developed the bulk of the “command plan,” the carefully ordered procedure for dealing with Hubble’s electrical power system.

She helped develop the procedures and computer code to send the commands that controlled Hubble’s batteries, as well as the commands that turned on and off the relays that allow power to flow to the batteries and other electronics.

This video features Deneen going over her unique bond with the Hubble Space Telescope.
